There are a lot out there right now somebody will wanna hit the rollers soon I know it

im on standstill right now until the rain stops and i burn through by bad gas

Terminator2

I hope it is just bad gas unless the 94 octane rated gas is not really 94 actual anymore. It appears to have the same or less knock resistance as 91 octane E-10 gas.

Terminator2

Nathans car at 100% duty cycle up top reads as high as 37lbs/min.

Thanks term 2, I see between 37.3-38.2 up top. Sounds like it may not flow more than the + but it's right with it. For 1/2 the cost it's a steal. Thanks

Whats the max psi it will hold to redline 6800-7400?

KMO43

The machine work on the turbo is done very well it's too bad the housing can't flow much more. I was saying for the price it can't be beat!

I wouldn't rev it out that high

So the +doesn't flow any more than stock?

Terminator2

A little bit more than stock but nothing amazing.

KMO43

What do you think could be done on E? Being from Canada I have never seen the fuel in person but all the big numbers for the stock K04 have been on E what do you think is possible on the K04r?

Terminator2

Hard to say until I can do one on E-47 and have him dyno it. Nathans gas is so bad it is knocking on stock timing and 0.85 PE lambda and 26psi. There is more left if I could actually advance the timing 4-5* like I should be able to do with 94.

KMO43

I was at 15 or 16* on 94 now I'm at 20* with 94 and meth

Factory skew or skewed further?

I have no doubt this turbo flows more and is much more efficient based on the dyno and logs I've seen thus far. Gobs of power over a factory KO4? Nah, but a much broader power band? Absolutely. I'll bet on E that it would be a very strong 370+, carried to 6500-6800 or so.

Terminator2

MAF is dead on zero skew because fuel mass is set stock and using gasoline not ethanol blend and no meth injection. Never seen a log of his car on stock K-04 so unsure as to normal flow on his car under his conditions but I do tune a lot of stock turbos and see around 35-36lbs/min normally on them.

Terminator2

That is where his should be around 14.5-15* max on 94 and 25-26psi but either his gas sucks or it is false knock. Looks like real knock to me though but hard to say without him throwing in a couple gallons of race gas of E-85 to see it it kills the knock.

KMO43

Well I think if you have some miles on your car and are looking to rev the engine a bit more this is a perfect upgrade it's not like you're paying over a grand for a upgraded K04 you're paying $495 for a newly rebuilt machined better floing turbo it's a great deal but it'll never be a ZFR

KMO43

I live in Alberta so we have husky and petro 94 here but I go to BC all the time and use his Chevron and have never had a problem but with that being said I've only been to the Island once with my car and it was years ago and I only filled up once

Terminator2

Could be false knock. I have seen bad purge solenoids cause incurable knock retard before especially at higher boost levels.

KMO43

Ouch i bet it took forever to find too!!

Terminator2

It threw a code eventually.

Terminator2

How is that thing liking the E-35 blend so far?

So far so good.

Fuel trims are a little messed up but that is to be expected. I haven't flashed the new log yet.

KMO43

eventually is the key word there

nathan112i

on the way home from work today i put several bus lengths on a 2014 wrx that wanted to play on the highway, i think friday i will fill up again and datalog. once me and term are happy with the tune i will schedule to hit the rollers
