Stock turbine. That's why I explain it as being smooth the bigger compressor wheel slows the spool a tad but gives a good increase in top end. Just spools a tiny bit slower than the K04 but the way it delivers power is way different nt all of a sudden like the K04 or ZFR. He machines out the compressor housing to allow for the greater flow from the bigger wheel.

It's the best $500 I have ever spent on a car. I would have bought this the day I ordered my car if I knew about it

He needs to get more info out about this. I wish he had some kind of numbers too.

KMO43

All we have right now is his flow numbers he's at 35.8lbs/min on a stock intake and exhaust.

I am going to dyno mine soon but my Hahn intercooler problems have been slowing me down. I'll be getting my new intercooler next week so maybe i'll try to hit the rollers right after that we'll see what I can do

That would be cool. Where'd you get the flow number?

KMO43

Next week I am willing to load the stock or GMS1 tunes and do logs, vids and report on how it drives

HP Tuners I'm thinking MAF flow lbs/min (that's where I got mine from) I hit almost 34 but i'm at altitude and had other non turbo issues I had to work out like bad intercoooler ect

You guys do realize that the zfr doesn't have to come into boost and be the tranny buster everyone is always talking about. Its getting old and annoying. I'll say it one last time, it's......all.....in.....the....tune...... you can have it come in whenever you want and there doesn't have to be this omg huge torque spike lol. Mine is ***** to the wall at 4000 rpms, smooth boost increase until then. It should be smooth and progressive. It's perfect, no need to come in earlier anyways and have it surge. The beauty of the turbo is tune to whatever you want your ramp to be, 3000 rpms full boost or whenever after, you have a huge window of spool range that you can pick, great dd turbo fyi.

There's also the price.

KMO43

Yes I 100% agree the ZFR is a better turbo fast spool more flow great buy. i myself am going to buy the 7163 this winter but for 1/4 the price the K04FTW is a great option and I run mine with no boost ramp and am not too worried about it. Just explaining the options if they were the same price the ZFR is better but for how cheap the K04FTW is and what it can do it's a great option!

I understand you have a boost ramp but you also swapped in an LSJ trans so you must be a little worried

tuned08ss

Also I want full boost before 4k

KMO43

I don't know why ppl buy a turbo and turn it down I think that's silly

tuned08ss

Exactly. I dont feel like buying a 4.05. Zfr is too expensive for my grocery store clerk paycheck.

KMO43

If I was going to buy a turbo that spools super fast and turn it back to 4000rpm why not just buy a bigger turbo that normaly spools at 4000rpm??

This sounds like it would be a good option if it really performs that well over a stock k04. 35 lbs/min isn't much though. I've seen that from my k04 when the temps are cooler (like 50s) and the air is less humid

Terminator2

It is a bit silly but the power is always there if the clutch and trans are built to handle the hit you just adjust the tune and wham big hit around 3500. The ZFR hits hard around 4500 even with a slower boost ramp. If you crank on it it spools hard around 3500. I like the S-256 ET as a good DD turbo as well.

KMO43

Ilike the 256et too but like the all in one package of the EFR. I think the 7163 will be a great turbo with littl to no boost ramp and making around or a bit more power than the 256et

KMO43

Well for a direct K04 vs K04FTW I raced my buddy who I met up to tune I have intercooler and pipes he doesn't and my meth wasn't hooked up I had 2* more timing and a boost leak (hahn fail) I had 2 ppl in my car he had no spare tire.

I let him go first we both started in 3rd as soon as I hit 4th he saw how I was gaining and just gave up. If we both hit it at the same time he would have pulled because of the slightly faster spool then I'd pass him right away even with the 2 passangers

I'd definitely be interested to see a dyno with this turbo or even an HPT log to see what kinda difference it could be. K04 just isn't doing it for me anymore. I have meth too so it would be a pretty good indicator of what I could get with this turbo

KMO43

Ya I'm on both of those for next week like I said before I'm just waiting for my new intercooler to be shipped. I've talked to Matt he'll be online later tonight he's mainly stock and I'm bolted with meth so we should be able to get some good numbers. I don't know who else bought them but I know he has done a bunch over the last couple of weeks.

Ok a good comparison would be great

KMO43

I think the best race for me is Aaron and he's 3hrs away but I'll be visiting him in a month or so so we could post vids if that works. I'll run him no meth to be fairer

Flowen

I've actually rode in Kevins car, and it's fast as ****. He has me tuned to 24 psi stock ko4, k&n Sri, zzp 3inch catless dp, and a muffler delete. Everything else is stock. We raced with my buddy and my gf in his car and he pulled on me easy. I think he was running 29 psi on the upgraded k04, and no meth. But you'd have to ask him to be sure

KMO43

I was running 28psi but it dropped becuase of my intercooler leaks. It was fun tho Like I said I want to come up there within a month and after Mark has his car going I think you should come here for the weekend and get a run in against him

What does the stock turbo flow compared to this this upgraded K04's 35lb/min?
