How much "boost" through a stock 14
I've boosted a few busas but how many #'s can a person push through a stock 14 engine safely. I've heard 4, 5, 6, 7 lbs. ??????????? pump gas only.

Im running 8 lbs of boost on pump gas. I have a schnitz EFIR that pulls 6* of timing
at 5 lbs boost off a presure switch.
I've got near 10K miles on my turbo bike with no problems.

If you plan on drag racing somewhat,7-8 lbs with good fuel and pull 5 degrees of timing. Bob's set up has lived this long for a reason its wright!! Beleive it or not it matters what kit you use as to tune up,but most of the 14s we do go out of here with 8lbs at 275hp and then some on average. The 14s hold up very well at this level and the only weak point at this conservative tune is the clutch for racing. You may want to use a lock up'or at the very least space the springs for street duty. Weak is probably the wrong word to discribe the 14 clutch but you get the jist of it. Bill...

Damn Bob, is the 14 your only means of transportation? LOL.
Bob, do you know how much power the bike makes with that amount of timing being pulled out of it at that boost level?
Jessejames, how about you, are you using a timing retard at all or nothing?

bob told me 297~ RWHP....
I decided to go with the same setup, but external wastgate, for progressive boost

Bob's got a KLR but rumor has it that he's working on a twin turbo set-up with intercoolers and maybe a dry shot to help the Killer when it's building boost. :0

Jesse is NOT pulling anytiming out but we are using race gas ... With pump gas i would think about pulling some timing out just to be safe ..

Here is the EFIR and presure switch set at 5 psi to pull timing.

GOOD INFO! Just curious why different kits vary in lbs of boost... 6 lbs is 6 lbs on a mr turbo or a muzzy kit?

Its more about the turbo and the amount of air it moves.
My bike wil make a pound and a half of boost in high gear cruising down the freeway !

Boost can be controlled by a spring, electronics or a combination. Also 8psi at 180F is not the same as 8psi at 225F......temps are a bigger factor on boost.

AV gas boys mix your own and increase the boost lvl's just as long as u have done the engine work... If you can get the bike running at 0psi atmosperic pressure you should see a performance gain and fuel savings. At 0 psi your already spooled up and ready to snap... Wild on the road. I couldnt imagine 1psi cruzing down the road... Ready to launch... Crazy!... I found the setup constantly building speed and power above equal to or above atmospheric pressure. With my set up anyways... I cant wait till I get 1 of these jems on my bike... Turbonetics... Ceramic bearings... Tell them where you want the boost. THey will design a turbo for ya's... They just need some information.

Bob that does not make any sense. I assume you run a wastegate spring and it opens at the proper poundage. Also building 1.5 lbs at crusing speed on the interstate shouldn't do anything but help a super quick spool to the wastegate spring pressure. Again 6 lbs is 6 lbs no matter how you get there. Unless your running an intercooler {and not many people do on a stage 1} I'm just curious as to all the different info on the amount of boost to safely push through a stock 14, 11.0-11.5afr, no timing pulled, average temp{55-95 degrees} pump gas. I also realize as an engine gets heat soaked detination is more of a possibility. I value your opinion Bob in that you have many miles under your belt on a turbo 14.

Dunkin,
you seem pretty worked up about what a 14 does on turbo, especiallly for a guy ridin a turbo busa... whazzaaaaap! ?   .
on a more serious note, yes, i value bobs opinion too, and I will return to lurking mode, and wait for response as well!

I have set up a number of turbo bikes over the years. I've been to the school of hard knocks.
Proper fuel for your boost level is a must ....... controlling detination is a must.
I've known people that have thrown a turbo on their bikes and did not make it 10
miles down the road and the motor was smoked, then they blamed it on the turbo !
Take a look in the mirror ....... thats what wrong with your bike.
I can tell you this 11.0 AFR is safe ....... 11.5 AFR is more power.
8 lbs of boost on pump gas will work. (with timing pulled out)
6 lbs boost max without pulling any timing.
BTW: Your correct about 6 lbs of boost is 6 lbs, but the impeller that you choose is what
makes the difference.

Dang that bike looks clean... I look after mine and I still dont think it is that clean...
I guess it has to do with where you live and ride...

Me worked up nah, turbos excite me what can I say. I'm thinking of doing a mild build on a zx 14.

I like both bikes, in fact I like almost all bikes, but especially fast ones....

Dub give us some more insight on your upcomming build. I've got a feeling you're going full tilt on your bike. Lee Sheirts told me pound for pound {boost} the zx is a little stronger than the busa. Sealing the frame is the only complaint He had. He could only run 12-13 lbs with out boost leaks. Velocity is building 2 prostreet 14's as we speak for a couple of fellows in South Africa. I was up in their shop 2 weeks ago and asked them about the frame sealing. Barry showed me some o-ringed plates he fabricated to hold 30 lbs of boost {600 hp} He told me these bikes would be fast as shit{7.20's} IF He wasn't sponsered by Suzuki He would consider running one himself. I'd love to go full tilt on a 14 but I've blown a big wad on the 08 busa turbo

I don't want to ruin the surprise, but I am shaving about 80 lbs off a stock zx14, in ways nobody has seen yet. Turbo build will be mild, 9-12 psi, motor built to handle much, much more than that.
Sadly, due to my location and poor timing, it will be 6-8 weeks before it is all done.
I had to wait and see what my income situation was going to be, before making a move to spend loads on the bike,
I have another extensive contract in the petroleum industry so its a go.
I almost went gsxr1000 turbo, and pulled out on that idea last minute.
The 14 has an awesome foundation, clutch, bottom end, and tranny.
looks good Duncan.
Is that arm thompson, or McIntosh?

I understand Dubious, can't wait to see what your gona through at us. Your very smart for building the motor fully initally, because I've never known anyone who doesn't want to "TURN UP THE BOOST"...... That arm your asking about is a Velocity custom arm.
