[QUOTE=40rty;6673532]Bahahaha ferrea valves??? no wonder you have to get things little by little. Yea, they are a good brand and all but your going to be paying a arm and leg for valves you can get elsewhere with the same strength and quality.


Also, one minute you have a turbo in mind the next you change to another, "would you like chicken or Lasanga, Sir.... Chicken or Lasanga..SIR!? Make up your mind already.


Really 40rty?...lol, come on man, don't bust my ***** on this stuff. I just wanna make sure I do the things that i wanna do, and in the right order

Ferrea valves are only like 350, and i want quality parts. Plus changing out my valves will give me piece of mind about the huge carbon build up we all have in these cars.
Lastly, i wanted the ZFR from the beginning, but when they said it was gonna be another 6 months or never, i started trying to find a replacement that is as good. The Pwerks looks to still be awesome, but not for the money...If it was 1200-1500, then i would get it.
I am trying to have a reliable, 425whp +/400wtq daily driver on 93 gas alone...

 

[QUOTE=AARON-SS-TC;6673695]This is just me but i dont think ull get 425whp on just 93... Might be able to get close to 400whp on a really aggressive tune, but im no tuner lol maybe someone else would like to chime in

 

I trapped 137mph in the 1/4 on the stock manifold. How bad could it really be?

 

[QUOTE=ixxgh0stxxi;6674064]Why do you say that? My car made 400/400 on a conservative 23psi tune and with **** not hooked up right lol. I was seeing right around 40-42ish maf lb/min with the original tune and around 47 -50 maf lb/min running 26psi and more timing. It's defiantly possible..

 

I always thought ur setup was a litte different than ours couse u have the tubular mani and stock efr exhaust housing so I didnt take ur car into consideration lol I don't know if those things helped to make a bit more power...

 

I believe i was talking about the bnr turbo on that reply to barely getting 400whp..

The zzp zfr turbo should be easy to get over 400whp

DAMN, MATT RAN A 10.99 ON THE ZFR??? WOW

 

I honestly couldn't say if it is better or worse, but zzp has proven the stock manifold to work just fine.

 

That's true.. how much did u get off just 93 with ur **** running right?

 

Only put the car on the Dyno that one time cause i never really cared about numbers. It gained a **** ton of power though. .

 

He can definitely hit those numbers especially if he plans on spinning 7k or more. You're limited to 6800 right now unfortunately considering you have 100% completely stock internals (particularly springs). Plus you also made 410/385 on 25psi with a very conservative boost ramp so your torque is a little lower than it could have been if we really wanted to push it more. Also don't forget that dynos read higher or lower depending on the dyno and correction factor being used. It's not a consistant figure set in stone unfortunately.

 

I know guys running 390 with stock ko4 so I'm gonna say 400 is easily attainable with the zfr

 

Yea that's true.. I know u can get my car to higher than it is now I'm just being carefull lol I know there's more out of it I'm just holding her back for now.. I can't wait to actually get a couple more things done so I can bring it back and really get u to get things goin hard!! With this updated tune from u bro its been nothing but smiles I love the freaking thing lol and made me wana do more .. goin to start saving up for a trans

 

390 on what fuel? And i bet it drops off before 6k rpm.

 

so are these gonna actually be available sometime this week or so?

 

And i know the car is capable with meth, and or e85 or e47 of higher numbers i just thought that 93 would have been at its limit close to 400whp on this turbo, i wish hptuners was capable of doing a dual tune that would have been awesome..

 

Maybe ft/lbs but not horsepower.

 

Agreed your not getting close to 390 WHP without dyno tampering or Nitrous with a k04.

 

I'm sorry but your full of **** and misinforming those that don't have a clue.

 

I wish I was getting the full potential of my ZFR. Damn wastegate and crappy 91. Once I get that wastegate tightened up I think I'll be ******* with e47. I'm going to a 1/2 mile airstrip event in November n i gotta be ready to rep the SS.

 

Also herd that Zzp brought the ko4 up to 511

 

On gas, right in the mid 300s for whp was all we could get out of the K04 giving it everything it's got. Torque is a different story because the same amount of airflow at half the RPMs is good for twice the torque. That means that if you could load the engine hard enough to get the turbo to max speed at 2500 rpms, you'd be pushing close to 600ft lbs. In that sense, max torque is mainly limited by the boost threshold of the turbo, whereas hp is mainly limited by the max flow rate of the turbo.

 

600wtq would be nasty...lol

 

Good information.

Those who are saying you can get more HP from a stock K04 without Nitrous or dyno tampering are misinformed and spreading wrong information.

Mid 300whp isn't out of reach as long as you're on E-Blend of E30 or better and/or meth injection. Nitrous is another step up but not practicle.

Let's hear it for the ZFR! I can't wait to get my hands on one. Hopefully by December my funds will allow me to do it and do valve springs, too

 

The stock K04 is capable little turbo but not 390whp, torque oh yea. I made 368whp 446wtrq with my stock K04 so yes mid 300's I can see.

 

368whp and 446wtq is rediculous, especially on a stock k04, but im assuming that was a dyno number, but not what you drove around on...either way, damn good numbers
