I did a 4.812 still need to dial it in too wish I had e!!!

 

At sea level on stock K04 and E-47 no cams just bolt ons 4.0 is possible. You are at ~3000 ft right?

 

3557ft

 

KMO43

Thanks for the updates. Hoping to be able to get ahold of Matt on Monday. Was told he had cores coming in a few weeks ago...

 

No prob I wish I had more time I'm a busy guy working 2 jobs but I try to keep the info coming

 

65mm billet wheel would be the Exducer measurement? What is the Inducer measurement? Factory K04 is 56mm exducer and a 43mm inducer. For comparison, BNR GT2871 is well... 71mm Exducer and 53mm Inducer.

Either way for less than $500, that's a hefty increase in compressor size, should see definite measureable gains. The turbine side isn't touched?

 

50mm x 65.9mm

 

thank you. If that was in one of the other 54 pages, im sorry

Okay Im on the band wagon, this sounds like a fantastic option for the price. What do you do, mail them a K04 with a check for $495?

 

I'd buy it with the $95 actuator too!!

 

I gave after getting half way through thread with no answers. Can I get some cliff notes?


1- Who has been running this and for how long? Reliable? Heard about premature seal failure from a local guy (cant confirm that)

2- We gains confirmed other than a dyno that showed 18+hp? But carried 50whp more to redline?

 

I've been running mine really hard for over a year without a single issue.

No dyno but I can hold 26psi+ at 6500

 

Theres going to be a HP gain. GT2871 from BNR supercars will get you roughly 50 hp gain. The ZZP ZFR direct swap on pump gas is also probably a 50 hp gain. Id say this wheel has to be good for 20-30 hp on pump gas and for that price that is pretty good cost to power ratio.

Now with supporting fueling mods and running e85 it will be more. I think that's what KM043 is trying to do but hasn't dyno'd yet. You have cams with the fuel pump lobe upgrade? and running E47 KM043?

 

He is not on ethanol, and i believe stock cams but with meth.

I have the k04r and should be going e85 in the next two weeks with upgraded intake cam with the bigger fuel pump lobe.

 

I'm in canada no E here American doesn't share 😟 I'm running meth with the actuator it holds really well but also I wasn't planning on dynoing.

If somebody runs E fully bolted with the actuator that'll be a good setup

 

It's gonna have more psi at redline. Some ppl are getting caught up in pure HP numbers. The real deal is the power band just went up 1k+. The k04 is good just doesn't have the ***** in the higher rpm rang. This k04r is the answer to ppl not wanting a 500hp cobalt but a little more pull up top.

 

basically from what Ive seen

LNF K04 factory________has a 43mm Inducer_____56mm Exducer________price varies..________32-34? Ib/min

Werksracing WR-1 K04+__has a 46.5mm Inducer___60mm Exducer________$1250, direct bolt on_____38.4 Ib/min

BNR GT2860 ___________ has a 47.3mm Inducer___60mm Exducer_______$950, direct bolt on______38 Ib/min

K04R__________________has a 50mm Inducer____65.9mm Exducer ______$495, direct bolt on______???

Hahn super20G kit_______has a 52.6mm Inducer___68mm Exducer________$1199, need BOV_____43 Ib/min

BNR GT2871___________has a 53.2mm Inducer____71mm Exducer________$1200, need BOV_____???Ib/min

ZZP ZFR 6758__________has a 54mm Inducer______67mm Exducer_______$1940, direct bolt on____49Ib/min

ZZP S256 kit___________has a 56mm Inducer______80mm Exducer_______$3100, need BOV______58 Ib/min

ZZP ZFR 7163__________has a 57mm Inducer______71mm Exducer_______$2240, direct bolt on____60 Ib/min

ZZP S259 kit___________has a 59mm Inducer______80mm Exducer_______$3300, need BOV______62 Ib/min





Those are the turbo options that I know of.

 

I'll have ethanol dyno numbers with the upgraded actuator soon... Just need the turbos

 

That's what I'm curious about

 

i have seen 37lbs a min in datalog and i am sure there is more, WG actuator would help alot too

 

I've hit more than 37lbs/min

 

If its 41 or 42 Ib/min, sounds awesome lol.

 

You can update the +---
I've seen 38.4 on the+ at 6300. I'm not carrying 25-26 at 6500 like he is getting on the r. May have to try that different actuator.

 

Ya it'll work well for you too. As always I'm at altitude and have no access to E so I'm SOL

 

That would be the k04+ or the K04r that your seeing 38.4 on?

 

"on the +". think he would have said "on the r" if he was taking about the k04r haha
