You do realize that the zfr and wr-3 are both efr6758's right? Granted I don't know the turbine wheel specs for the wr-3 but I would have to think they are both pretty similar.

 

I know I know. I say I'll go bigger but I really can't justify it. I think really that whatever I'm at now is almost too much from time to time. Like anything over this would be overkill and the power would be completely useless. I'm just gonna stick it out and ride with the zfr!

Hey hey. Don't be yelling at me. I'm lazy. Haha.

At least I have a bigger turbo.

Hahaha. How about it. I do remember telling you that...

Maybe but you are looking at 29-30 psi and a big torque shock to your trans at 3800-4000. Sams trans did not last long at 27-28 psi with the zfr on 93.

 

Well yea if you're going wot all the time

 

29 psi 100 octane, do it. That video of ZZP with 3rd gear just going from 60-100.. Yea that's what it will do.

 

Ya I definitely beat my old trans to death. I'm surprise it lasted that long. Only like 3-4k mikes with the zfr and it was done for.

I wonder what psi ect it would take to hit 500whp on the zfr with the following mods:

Fueling: bigger injectors, cams/lobe, (5th injector needed?)

Motor: stock block, zzp rods, wiseco pistons, arp head studs, ect

Area47 tuned full e85

 

I wouldn't do full e85. I don't think you can hit 500whp+ on that gas. 35 psi I'm gonna guess LOL

 

the most you will hit with a 6758 is 500 crank and . 500whp 40lbs a boost probablly if not more

 

Really? 40lbs holy crap, I was thinking 30lbs would be close to high 400s

 

Yes full e-85 will require a 5th injector at that power level.

 

Zzps zfr dyno graphs show they hit 515whp with 28.8lbs and 540whp with 35.2lbs, although that might be with the 2.1lnf.

 

Meh depending on the fueling, I sort of disagree. On e35 at 25.5psi I hit 421whp with a 6758 which is just shy of 500bhp factoring in a 15% drivetrain loss.

Full e85? **** man, I need a 5th injector now to safely go past 25psi and that's an e35 blend. Never mind straight e85! Upgraded can lobe and 5th injector would probably be an absolute must with that sort of fuel demand at that power level.

 

And no one has come even close those numbers with a zfr. Zzps dyno reads high.

 

Well I've been running cams with the upgraded fuel lobe for a couple months now on full e, but going to put the bigger lnf injectors and a 5th injector in also most likely.

 

True, but I don't think many people have pushed a zfr to 35lbs with the same mods and fueling

 

10% driveline loss is more like it :p

 

515 whp at 29 psi is still a lot higher than anyone has made with a zfr.

 

I think people look at my wr3 graph and forget it's not a 6758, it was a custom letup with PTE Which was planned to be released then things happened which stopped that from happening. Pwerks then switched to using an efr system. Mine is a little bit bigger then the 6758, and spools slower. Although I don't mind cuz I'm really not hammering down hoping to get full spool by 4k anyways haha

 

I wouldn't be so sure. A GMS1 car made 264whp on ZZP's dyno. Don't go spreading false information.

Their 'lofty numbered' ZFR car trapped 136mph, much higher than anyone elses ZFR; thus the 500+ doesn't seem out of line.

 

Sorry but their mustang dyno reads high. GMS1 on a properly calibrated mustang dyno is around 230 whp.

 

that was an over exaggeration. at 25psi on 93 with hp tuners old beta i made 416whp at 25psi at 6500 with a whole lot of room to grow and make more if i wanted to supply more fuel and boost.

 

That car is damn fast if it trapped 136 on a zfr.

 

lurker chiming in here;

I thought that a properly calibrated dyno was registering a little over 230whp for stock SS/TC's??

 

I always thought it was 240whp.
