39 lb/min stock turbo? Do u have any screen shots? Thats insane. 8 lb/min less than a ZFR.

 

let me know how you like the ZFR with trifecta. i will eventually go that route

 

Ok, so you understand the flowing of 40 or whatever lbs on stock turbo..

First off that turbo don't flow 40lbs per min so that is obviously incorrect. Now, if this is on ethanol, your skewing the top table for fueling unless you change the injector tables a little for the e. turbo isn't flowing 40 your skewing the maf cal to show 40/ for fuel.


If on pump gas, your obviously have something going on. You can't change efficiency.

Most I have ever made on pump is 37 and that isn't skewing the damn thing, that's on 94 octane and what the turbo pushed out...

 

No guys running trifecta tune from stock turbo... I didn't purchase new tune yet I'm flowing 39-40lbs a min @ 24psi the zfr is on the car! Most I saw with ko4 was 35 when it was very cold out usually 34! This turbo seems to spool a lot later than ko4 like full boost @4000rpm. It must be the tune when it spools it pulls HARD!! But I don't feel as much gain as expected untooned! Car is running 13* of timing ramped to 15* up top! 12.0-12.2 afr and 24 psi. No knock and iat2s are always very low. Trims are still +-5 or less. Where can I get gains? 39lbs a min is 390 whp give or take right? Sorry for not fully explaining. I hope I can pull a lot more gains from a retune!

 

one thing is sure, eric will install my kit if a kit i have to put

patz24 is very good with hpt and i have acces to him, but vince ll do mine.

a good installation ll make tuning easier. 39Lbs MIN is ton of HP for Fwd even you have low timing. u ll surprise every single one that want try against you

with my k04 and 30lbs i surprised lot of people. i wont guess over 38lbs what people ll say about Rose power

 

Turbo seems to be spooling late with the k04 tune and i have traction in 3rd with freezing temps! Vince sent me an update today and said he made some vvt adjustments. I'm unable to log due to lake effect snow but at least I can snowmobile! Anyways at this point in time before the tune update the zfr is less power than I expected defiantly not 400whp. Starts spooling around 3500 full spool at like 4000-4200 and pulls hard past that to redline! I wish I could do some pulls but can't in the snow

 

My 20g flowed 45/48lbs per min, my early 25g was 55-57, my new setup is more.

My Efr 6758 guys flow 47-51lbs per mins

 

How much boost?

 

24/26

 

I was able to check out the spool with the tune update... Efr spools much faster! Still can't do 3rd fear pull due to sub zero temps and snow it's like 10 below zero right now!

 

calm down and chill out. u ll like it as soon as sun ll warm up your city

i guess it is harder to write a elite tune when your log are not optimized.

be patient, it ll pay off

 

Dyno results, 389.6whp and 409.2 torque. ZFR trifecta 25psi on 91 oct, timing is around 10Running this setup since 10k and no issue at all.

 

Damn, nice^^!
