Muzzy Race Cams and Pro Pipe Test Results
Just finishing installing the Muzzy race cams and pro pipe on my 1361 ZX-12R. First we installed the cams and tested the horse power gain without changing anything else. This test was done with Muzzy's regular exhaust pipe. The cams were degreed per their recomendations. Then we left the bike on the dyno and changed the exhaust pipe to their pro pipe. We didn't change anything else. The following are the test results. All numbers are SAE corrected. Pump gas, 93 octane was used. The dyno was a Dynojet 250. All numbers are the best results obtained.
Race Cams : power went from approx. 203 hp to 207.3 hp
Pro Pipe : power went from 207.3 hp to 208.4 hp
I was pretty happy witht the gains obtained with the cams but very disappointed with the pro pipe results. Was wondering if anyone one else has tested the pro pipe and what their results were. Muzzy's suggested to raise the rev limiter from 11,700 to 13,000 and better gains will be made from the pipe. I have not done this yet.

13,000 is a lot of "R's" On a Stroker crank!

Seems like you need to finish the testing per Muzzy recommendations before you can evaluate how unhappy you might be with the new exhaust. JMO.

Whats the mean piston speed at 13,000 with the 1361 crank?

so you picked up 1 horsepower PEAK swapping pipes but what about area under the curves for both I would like to see the actual charts let me know if you need a hosting source I can post them. 4hp on cams that's it? what about the curve do they hold on longer than before?

This info was exactly what I've been waiting for, Thanks!. One thing though, Muzzy does say you need to re-map w/their pipe. I almost think it's possible to lose power on a different pipe w/o a proper map, and probably the same would be true w/the Cams. Please Keep us updated. This kind of info is exactly what is needed!

How do you raise the rev limiter?? Do you have to switch to the EMS??

I talked with the dyno operator for Tim's bike for quite a while.
The fuel curve was right, he know's what he is doing.
The pipe lost considerable power and torque through out the midrange, losing some was expected.
We all assumed the bike would show an increase with the Pro pipe by simply bolting it on and adjusting for fuel. Now it seems a pricey box is needed to raise the rpm limiter, WHEW!!

Fast cost money. Faster costs more money. Fastest, well, I think money is no longer a factor, because if you have to ask, you can't afford it!

k bryant,
It's not just a question of spending more money, Tim can afford it....The problem is that nothing was mentioned that the rpm ceiling had to be raised for the pipe to work, only a large displacement engine like a 1361 or a higher reving small engine would benefit.
Bergie,
I'll see if I can get a copy of the dyno charts and send them to ya.

Agreed. Leaving that info out about the rpm ceiling is kinda a bummer. My "tongue-in-cheek" (sunshine smilely face winking noted) statements are unfortunetly a reality of wanting to go fast.

The ZX-12R "Pro Pipe" is a new design from Muzzys specifically for ZX-12 race engines. Designed for larger displacement and higher revving race engines without regard for "street" performance needs, this pipe is a four into one, large tube tapered design incorporating a high flow merge type collector. The pipe features TIG welding throughout, separate spring mounted head and tail pipes, and aluminum mount flanges. Power increases of up to 6% over the standard Muzzy 4-2-1 pipe can be achieved, but the exact increase will depend on your particular engine's configuration and flow requirements; that is a 1270 with a very high RPM limit or a larger engine such as a 1361 and larger would benefit the most. The ability to run a higher than stock rev limit will allow you to take the greatest advantage of this pipe's increased flow capability.
Titanium system weighs 9.4 pounds, the stainless system is 12.9 pounds
Note: We do not recommend this pipe on a stock ZX-12 as this is not the intended use of this design and performance may not be satisfactory on a stock displacement, stock compression engine.
Right on Muzzys site..

My intent on posting these numbers was to just ell everyone the results I obtained from these two products. Everything Muzzy's says on their web site is true. To gain 4-5 hp from thier cams is a pretty impressive gain over stock cams. We all know how good the stock cams are. Just expected to gain a little more peak power out of the Pro pipe at the normal rev limiter.
Was hoping for a 2% gain.
Rac4it - I will attempt to post the dyno charts as soon as the dyno operator gets back into town. He has the software. There is a big drop in the horse power and torque in the midrange using the pro pipe. Torque drops about 8 ft-lbs max and horse power drops about 6 hp max. This does not bother me. Looking for top end performance. From 9000 rpm up, the Pro pipe out performs theit regular pipe by approximately 2-3 hp until they almost merge at the rev limiter.

Question for SWFT. The EMS is universal to ALL FI bikes..correct?? THe same system for the ZX12 is also used for the Busa...correct?

zxlnt,
You are correct.
What I was referring to was the original post about this pipe. Doug said to re-map for best results, nothing about upping the rev-limiter.
I do understand that for maximum results the bike needs to spin higher but I was honestly expecting more at 11,600.
I stand corrected (half-way)...:-)

tn1361,
thanks for taking the time to post the results. This is exactly the kind of info which is useful to us "non-pro" guys.
You ought to splash some Nutec SP5 in yr tank. 5-7% hp increase is what I got with NO mapping changes.
I assume you had the Muzzy cams at 105/107 (their rec).
what were yr stock cams set at? 105/100??? other???

I have never run nutec in my bike. Dyno operator claims the remapping is not necessary with nutec. 5-7% hp increase is a hugh increase. Hmmmmm. Might have to try it.
Yes, the new Race cams are set at 105/107. My stock cams were set at 105/100. The shape of the hp and torque curves did not change that much between the two settings.

With my 13:1 1361 I got 3-5% incr, but with higher compression on my 1427 I got 5-7%...
