Muzzy Fuel Pump=PC3 Adjustments?
Just finished installing the Muzzy pump on my bike. I was wondering if anyone knows approximately how much richer, if any, the bike will run without adjusting the PC3 and how many numbers had to be taken out of the box. I'm sure all bikes may not respond the same way, just trying to get a starting point. Don't have the time for a re-mapping before the next big race.

good question...prolly easier to plumb in a fuel pressure gauge to see how much higher it is?

If i remember correctly, there is no "actual" change that can occur. The fuel pressure regulator remains the same, so the muzzy fuel pump is cool because you get a nice Muzzy sticker. Unless you increase your fuel consumption enough to lower the fuel pressure, the stock fuel pump is not even being challenged. The volume of gas that the injectors utilize is control by the pulse width(pc3 up to 45) and the actual injectors. Both of these are not capable of being maximized by our motors without flooding the engine. IE all the negative numbers in the maps!!! Nobody needs 45's to establish the correct 13:1 a/f ratio on any size kawasaki motor. There has been a past discussion on this subject. Others here have a greater technical and mathmatical info on the usage and limits of the fuel injection system.

Kevin was claiming a nice dyno increase by simply installing the fuel pump. *shrug
Ive noticed an improvement (on the street) with running all 45s above 8k or so both on motor and on spray.
Plugs were a bit toasty..but not damaged.

YCIS, your improvement i am not challenging.....bolt on improvement?! I don't remember Kevin stating that ONLY the bolt on made any changes. Think about it, if the amount of fuel is contoled by 3 things:
1) Fuel pressure
2) Pulse width
3) Injector holes total volume
1a) Maximum Fuel pressure at the injectors is controled by the pressure relief valve not the fuel pump. So a the high volume pump cannot increase the fuel pressure.
2b) Pulse width is control by the oem computer or computer plus power commander.
3c) Injector holes can only allow a certain volume of gas to flow through per milisecond. That volume is fixed based on the diameter of the holes. Lengthening the pulse increases the open time or squirt time. Increase pressure will also increase the amount of gas that can get squirted in the same pulse width. But the pressure is regulated by the relief valve.
Conclusion, unless more things are changed, the muzzy fuel pump will NOT add to anything to any size motor over the stock fuel pump. Tech heads please correct me if i am wrong!!!

After installing the MuzzPump...I remapped (tunning link) the 100% throttle and got...180+HP (have to look again for exact #s) that's the highest HP from John's bike to date...The link DID take fuel out for sure...I DO remember that...
Busy as can be but...I have to map a GSXR750 shortly and will look at John's maps to see how much fuel was taken out...
Don't get pissed if I don't make it back today...

Ra12, I don't have time to go into it right now (It's late and it's been a long day at the track) but you're not exactly on target here. The stock fuel pump starts to loose efficiency at about 200 hp. You are on the edge as you approach that. The big pump puts you back in the meat of the pump efficient curve....
The new pump usually requires about a 3% lean out to keep the same A/F

Thanks guys. My 1361 is already at 204hp and it just received a shot of nitrous. That's the only reason for the bigger pump.

I would suspect Doug is talking about real live horsepower without the drugs and steroids of NOS! Fuel is horsepower and to get two hundred ponies with fuel is a trick and it is not nearly the same trick as using NOS with the fuel.

Zhooligan, you know EXACTLY what he(DOUG) is or not talking about and EXACTLY what I am saying. These are just motors, ie: simple AIR PUMPS!!!!! What part of getting 200hp is a trick?! (Maybe the trick part is how you get your dyno or your friends get their dyno to read over 190hp from a 1270 and also the way you and your "friends" word the responses?!) Sometimes i wonder if you guys consult an insurance defense attorney to respond to these post.........cause the TWIST on stuff is absolutely sickening!!!!! BARFFFFFFFF!!!!!!!!!
What parts of our electric fuel pumps become LESS EFFICIENT(twist) after the motor reaches 200hp?! We all know that they don't run faster or slower, they just run....on to pump until proper pressure.
The physical limitations of the fuel pump is NOT hp related! It is capacity related! If the fuel pump provides enough gas to make 200hp, then it will always provide enough gas to make 200hp!!! All car racers using carburators know that when you press the pedal to the floor and the engine starts sucking more air than gas,,,,,,,ie lean,,,,,then the motor starts to sputter and cuts out, just like running out of gas. Do we then say that the carburator is BECOMING LESS EFFICIENT. Do we say we need more fuel pressure?! NO,,,,we say we need a bigger Carburator that can allow more fuel to flow.....ie bigger cfm Holley....Then fuel pump can be enlarged. To get what the "Muzzy fuel pump" is supposed to deliver, then you have to replace then entire fuel injection system!!! It is simply an electric fuel pump that turns on and off!!!!!!!!! You can go to NAPA or AutoZone and see that there are many sizes of fuel pumps. Big ones and small ones. They all just turn on and off. Fuel pumps do NOT measure anything!!!! No more than the windshield wiper sprayer becomes less efficient if more bugs are on the windshield!!!
POINT::::They just pump fuel!!! What physical components has been change in the Muzzy pump to make it different from the OEM?!?!
Because our Fuel injections on all our bikes are the SAME!!!!!! The computer on all our bikes are the SAME!!!! The pressure relief valve in the fuel system on all our bikes are the SAME!!!!!!! Pushing more fuel WITHOUT more oxygen is called "flooding your motor!!!"
One last question for Zhooligan or Doug,,,,,,,,,,How long does it take for the OEM fuel pump to pump the gas tank empty if it is not hooked up to the fuel injection. 1min?! 2min?! 3min?! 4min?! 5min?! 10min?! 15min?!

I am not certain how much of your post is insult versus question, facts etc. Let's address the pump issue first. I personally have know idea how many gallons or litres the stock pump can pump per minute and or the same for the Muzzy pump. I do know that the Muzzy pump can provide more fuel. I also know that horsepower is a results of combustion. Combustion requires fuel, the more fuel the more combustion as long as adequate air is available. My comment above was intended to point out that in the case of Nitrous you not only had the gas / fuel that is supplied by the pump but also the Nitorus that is supplying additional fuel or at least an accelerant that gets more out of the same amount of fuel. As for Napa etc having all types of pumps etc. not sure where you are heading there. But lets look at a 550 cubic (probably more cubes thene that)inch AA fuel dragster. Do you honestly think it will make 2000 04 5000 horsepower as they claim to make these days with you Napa fuel pump? The pump only has to deliver about 25 gallons of fuel in 4 seconds or so. Of course not. And that is why they have a special fuel pump capable to deliver the needed fuel. And it is this theory that sells Muzzy pumps. Your hot rods that you speak of have a mechanical fuel pump that provides enough fuel to carburator(s) that you have not encountered fuel starvation yet. I don't claim to know if and when a ZX12 fuel pump will reach it's capacity. I suspect that Muzzy has spent a few dollars in research and have a better idea. I value Doug Meyers opinion on the 12 more then yours as I would value your opinion in your area of expertise as well.
As for the comment about getting your friends dyno's to say this and that and effectively calling folks a liar.... I can't speak for everyone but I can for myself. The dyno that my business owns has never been considered a happy dyno. In fact most people wine and cry about it because it seperates the bullshit from the truth. I don't know how long it takes to pump the tank empty, Nor do I intend to check it. My tank is a gallon larger then stock so even that data would be wrong in your book. I can tell you that perhaps we will have a chance to meet on the street and see if you find the smell of my exhaust rich or lean.
As for the twist being sickening, I am not certain where that shit came from. Again I merely threw out a theory based on naturally asperated horsepower versus NOS enhanced. Apparently that twisted something that makes you uncomfortable. Because I know this for sure, my posts have not been bashful. I have not accused anyone of making me sick or tried to infer that they are dishonest and stupid unlike your post above.
Oh by the way the comment about the parts all being the same, the computers the same, pumps etc. Thats a very naive statement. They are all built to a range of tolerances. On a given day or given bike there are parts and pieces that are miles apart on the same bike. We have seen as much as 4 horsepower difference in the ignition box on an R6. Take 6 different R6s and swap the ignition box and out of the six one box will make more power that the others regardless of the bike it is put on. And unfortunately 1 of the boxes will make less on all of the bikes. Look at the head on your ZX12 and set it next to 6 other stock heads. You will find the ports, fit and finish to be different on all 7 of the heads. Some guys luck out and get the good head and some don't. It is safe to say the bikes are made to be similar. If you remember the IROC seris, the cars were all identically prepared in everyway. Except there was always a car that everyone agreed made more power and was faster then the others as well as there was always one slower then the others. So again before you get pissed off and start insulting people you might want to take a look at reality. Muzzy and Doug Meyer can't say for certain that a 1270 kit will make exactly 192.4 horsepower because there will be 1270's that will make 185 and an occasional one making 200. I have never seen one myself make 200. low 190's yes.

Facts are facts and the numbers don't lie!!! Just address the numbers concerning how long it takes for the OEM pump to empty any tank if you know the volume of a full tank,,,,,,You don't want to address (as stated) because the conclusion and "FACTUAL" implications are not comfortable to some.
quote:

Zhooligan, this is exactly what i am talking about!!! The ROMANTIC THEORY about using a "special Muzzy pump" to get more power sells pumps!!! (Dang you worded that good!!!) That is misleading!!! I have withheld many a comment on many "misleading" implications by several popular folks. Half truths and incomplete information and better yet the redefining of terms is unneccessary and I for one am very tired of it. Just like when Kevin was asking for information about carrillo rods. You, Doug and anyone else that has stroked this motor KNOWWWWWWSSSSS exactly where those bolt heads hit. You know exactly, what needs to be done to the starter gear, and exactly if the counterbalancer even does anything. Yet, when ask by Kevin, you cannot even give a complete answer!!! I just watched and read your responses until i was pissed. So then when I respond, you make a wise crack and redirect the focus of the thread to YOUR choice of what you did with your motor. If you don't really want to help, then just be quiet!!! Kevin, email me privately and I will tell you anything you want to know without the secrets!!!
Secondly, last time i checked my motor was built according to specs measure to .001 inch. There are tolerances of course, but those tolerances are in thousanths of an inch!!!!! Every motor is different yes, but lets keep that in perspective. Because any part can be interchanged they are not different enough. My motor varies from pull to pull so what is your point?! Is that because the tolerance in my motor are changing between pulls?!?! If you are trying to explain your HP based on engine tolerances and you have a "fast" monday motor, then that died when you made the first mod.
My original point to begin with in this topic was strictly regarding the FACTS about the OEM pump!!!
But, since you want to press the issue, I have a NEW question......
1)What was the difference between the Muzzy clutches vs OEM clutches?!?!?!?!?!
2)Or the Falicon billet clutch basket vs Muzzy billet clutch basket?!?!
3)Or the MTC snowflake vs the Muzzy lockup?!?!
I personally don't care that things can be the same with a different name, just keep all the information very truthful!!! The desire for money can sometimes lead to misleading or incomplete information.

You are saying that I am witholding information such as the bolt heads issue on the Rods? Interesting. I own a Construction Company as well as some Gas Stations. I am Carpenter, I have degrees in Civil Engineering, Architecture, Construction Management,Education and yes law. I am the true definition of an educated idiot. Motorcycles, cars, trucks, skydiving, hang gliding, and scuba diving are some of my hobbies. My tow vehicle, a Dodge 1 ton Cummins makes 556 horsepower at the rear wheels and 1367 ft pounds of torque. Good enough to get me a 119 mile an hour ticket pulling the race trailer!! If it can be tuned or modified I mess with it. I am an Expert Road racer, a Moto Crosser with a National #1 over 40 expert plate in my cabinet, I can ride or drive the wheels off of most anything, and I can be a pretty damn good mechanic when I want to be. That said, I hate working on my own shit. Consequently, I usually pay proffesionals to build and work on my stuff. My race bikes, street bikes, works engines etc. are all built by Mike Velasco of MVR. I have in fact paid Mike hundreds of thousands of dollars over the past years to build my stuff, as well as be my crew chief and head mechanic for the race teams etc. I rent space in his shop for the dyno business, and I stop in at his/our shop fairly often, and yes I do on occassion peek over his shoulder but I do not even pretend to understand the black magic and science that he puts into his engines. These are the engines that set and hold the records on road race tracks all over this country and for that matter the world. And it his experience and expertise that I pay for. That said my answer on the rods for example was as forthcoming as I could be. I posted the clearance issue the moment (a couple of months ago) I heard and saw it. I didn't fucking personally grind or touch a thing, nor did I say so, in regards to the work. I have nothing to hide. And I would challenge you to give a detailed explanation of how and what had to be ground and shimmed to make it work if you had done the work. And I certainly did not hire Velasco to make an installation manual nor did Carillo provide any instructions.
I have however spent hundreds if not thousands of hours watching, kibittsing and participating in the mapping of many a motorcycle engine. My own bike is a result of thousands and thousands of dollars spent along with hours and hours of dyno work. I believe Doug made a statement about the best results usually are had by those who have put the most work and or time in their engines. My 1361 demonstrates that. I have always lived by ZX12 Girls moto "if you can't beat it by a faster bike".
As for the comment about the differences between Muzzy parts and others? It's pretty simple for me. They have taken the time to put together a good selection of kits and products that fit and work. Whether they are the same as other products or the same product repackaged etc. I don't care. I know that their clutch basket and hub works. The clutch gets oiled where the stock set-up doesn't. And I can find the part without issue. And I know where to look next month and next year when I need replacement parts. I have not actually seen Muzzy or any other vendor blast anybody elses stuff on this board. Maybe I have missed something there but I don't think so.
I don't know what it is you do for a living, but I would assume you expect to be paid for your work. I don't build buildings for free, nor do I give gas away. Actually, these days the market is such that I do sell my gas for less then I actually pay for it in hopes to get people into the convenience store. Boy is that fucked. What I find interesting about your statements above is that you apparently believe that MUZZY and or Doug should provide you with their R&D for free. When is the last time Factory Kawasaki or Honda or any other manufacture got on line with you and shared their secrets. Or even talked to you? Did I hear "NEVER". I have appreciated the technical info given by Muzzys as well as others on the board. Your point of view reminds me of the people that show up at the shop and want us to put their bike on the dyno for free the first time and tell them where they need to add and or subtract fuel so they can map their bike at home. They actually get upset that we charge them for the use of the Dyno. In this case Doug shared some information, you didn't like it so he is a liar and not being truthful, and I am a liar because I threw out a possible explanation about Dougs comment about 200 hp being the area where the pump sees it's limits. This board is susposed to be entertaining and fun.
Let me also say this, when I have been asked specific information, usually by e-mail I have gone out of my way to answer questions and or find out information. As a matter of fact, I answered 4 E-mails from people on the board tonight. What I find very offensive is your inference about truth, your being truthful and apparently myself and others being untruthful. And it would appear that if I don't know the answer I am being less than truthful. I personally find that offensive, and frankly it pisses this oldman off.
The last comment about money. That is really funny to me. I have not made so much as fucking dime off of this board or anyone as a result of this board. I can say that people on this board have received from myself and or my business free information, free dyno services, as well as free parts, pieces and accessories that I have had bought for my 12 and not used. I have even paid the fucking shipping costs.
I don't mind sharing ideas and information, but this kind of bullshit is just that bullshit. There are many things I can tolerate but being referred to as dishonest is not one of them. If you really want to call me a liar, e-mail me a time and place you would like to do so to my face and I'll be there. If I have taken you out of context I apologize. But I do want to make this clear I have never been less then candid, nor do I have any agendas on this board. I joined this board to share ideas and fun stuff. Not to argue.

hahahahahha,,,,,,,,I see that i have pressed a button!!! I also see that not once has my tech QUESTIONS been answered or addressed.... You are TOO SMART (by your own admission) to not be able to discuss the technical aspects of a electric pump. So the avoidance is speaking the answer. I give you and Doug permission to make me look stupid by answering the easy questions about the ELECTRIC PUMP!!!
Zhooligan, this thread is not designed for you to have to validate yourself as I already believed that your accomplishments were/are quite respectable and frankly I could use to listen to you in many areas to be MUCH MORE successful.
I AM NOT CALLING YOU A LIAR!!!!!!!!!!
Exaggerations, half truths and incomplete information is techniqually a lie, as we teach our children that this is wrong. But, for the intent of this board and particularly this thread it is not that serious. I repeat,,,I AM NOT CALLING YOU A LIAR!!!!!!
I simply would like the issues about the FUEL PUMP to be addressed! Yes, I do believe that all things about the Muzzy products are not CLEAR!!! It is the Non-Clearity that expectations get messed up for the consumer. It is also this Non-Clearity that gives companies room to use a "Theory" to sell the product. When in fact the description or name or the product leads the mind to think in a direction that the product can not or does not actually uphold. Motrin is a prime example of this......Motrin is sold in 800mg tablets or larger. Motrin is an expensive pain reliever and anti-inflamitant. However, we are not told by the COMPANY that motrin is advil. When the company makes a 800mg advil tablet they RENAME it and call it motrin and charge more!!! This to me is srewd and disceptive business practices. This is what i am exploring in the thread to VALIDATE that Muzzy's would not to such a thing to their customer base. However, my simple questions are definitely not being answered about the fuel pump, and results such as YCIS and hundreds of others are having to me screams,,,,,,,,,ADVIL!!!!!!
This board is about the sharing of words about the bike that we own and enjoy. However, i will demand that WE ALL be treated with truth and intelligence as good loyal consumers. If we are getting the royal "TRICK" then we all need to chime in and demand that a greater level of integrity be practice when marketing products!
ANSWER MY QUESTIONS PLEASE!!!!!!!!!

Thanks for your response. I will let Doug respond to the pump question as I am not a hydraulics expert. And I don't have specs on any of the pumps anyway. And for the record Dug Meyer and I are very old friends. Afterall we met once (1) at the Muzzy breakfast at Laguna Seca this year. He said hello I am Doug Meyer and I said hello I'm Zhooligan. I won a T-shirt because I was voted as the guy (at the breakfast)who had spent the most on his 12.
I'll see if I can Necromancer back onto the site. He is a hydraulic engineer and would probably have a near orgasmic experience doing the math! Of course if it were all math then there would be no need for the actual race!

I believe Muzzy said that their pump would support roughly 350hp or was it 350 lbs/hour? Anyways, not every fuel pump advertisement goes by GPM. Lbs/hour is another way of stating flow. Basically, their pump will pump and lot more than a stocker and if you have a badass motor, you might need one. If your bike isn't running out of gas, you probably don't. If you're concerned about being on the ragged edge of the stockers capability, buy the Muzzy. I don't have to worry about about being short on fuel now, especially when I hit the button.

I ran into a "Fuel Delivery" related problem not too long ago....see the "Engine Hurt/1270?" thread.
1) The stock pump is a 200 lb/hr. pump. Min. flow rate is 83 ml or more in 3 sec. I got 110 ml in 3 sec on my stock pump.
Muzzy pump is a 350 lb/hr. pump and flowed 240 ml in 3 sec.!!
2) When I had my injectors cleaned and inspected by R.C.Engineering, I was given this info.....
Before clean and service (as received)
B.S.F.C. of .50 : 192.8 h.p. at 80% Duty Cycle / 43 psi.
Average Flow rate : 316.3 cc/min.
After Cleaning.....
B.S.F.C. of .50 : 195.2 h.p. at 80% Duty Cycle / 43 psi.
Average Flow rate : 320 .3 cc/ min.
Crunch the #'s......
My stock fuel system was "Good " for 192.8 h.p. w/ stock pump and injectors w/ @ 13,000 mi. on them.
My 12 at the time was making 173 h.p. on the dyno. Add 8% for ram air above 150 mph : 186.84 h.p.
Now throw in VP-MR1 fuel (100% mix) and jet(REMAP) accordingly. The VP is good for another 5%!!
Due to the fact that VP is oxigenated....I had to richen the map quite a bit! I exceeded the 80% duty cycle!
With @ 196 h.p. on tap the morning I did a top speed run out here in the desert last spring....I exceeded my fuel systems ability's and melted a piston!!
Doug ran into simular problems (Don't know what fuel he used) at Bonneville and hurt a couple pistons before discovering the source of the problem.
I now run the big pump w/ my 1270 and good thing!! I had to richen my map that was done at Dynojet(Vegas) up to 25% almost everywhere!!
Result : 202.5 h.p.
