Kraftwerks Supercharger Owners Thread

We are also at 2200 ft elevation.. down in LA the car is even more intense. The fuel injector size shouldn't matter unless your running out of injector. Also the RPM on his Dyno showed 7340, and my car, EcuTek both show 7750 and thats when its at the 19 psi (18.7 to be exact).. According to the AEM fail safe, i honestly don't how accurate it is, if I'm having the Auto trans slip or not at 7300 RPM its just over 16lbs due to what Church said was a spike right around the 7300-7400 rpm mark, he said it is either the ecu telling the trans to shift or its slipping, on the street i do not notice it.

And the last issue, my car is not as easy to tune as others, the car runs great on the tunes, but all but Moto-East had start up issues, and its always had them before the E85. now that its cold i really havent had a issue with it, but thats why we assumed it may be a fuel pump issue. I do have a Map from Bill that is a little leaner, but it had more start up problems then the one i have now. We have chalked it up to the ECU swap that Toyota did, as i saw personally the same tune work on another car with the exact same set up, but wont run for crap on mine.. Kit wise no issues, but the tune has been a nightmare with my car. It may or may not have anything to do with power, but Church said there was more power in it for the lack of timing and as rich as it was.. right now im happy with it.

Definitely seems like a lot of factors to be considered. Don't think (could be wrong) elevation is an issue since psi is the same everywhere, like pounds. (By poundsI mean weight) I believe it's only an issue with NA cars really, but someone else is (most likely) more knowledgeable about this than me, and like I said I could be dead wrong about that. Either way I'm sure it is in beast mode with more left on the table, especially after how you've explained it. Good luck with the tuning, looking forward to those maxed out numbers!

So need opinions here. Who has the c38 with a header that is running a delicious flash n go, or the moto East tune.. Opinion on drivability and any numbers on power? Trying to decide on which tune for my spring install. I'm keeping my stock injectors as well.

I have been told, but havent verified it, as when i was down in LA my AEM shows AFR instead of boost and i didnt bring the laptop to swap it over, but ive been told that a turbo does not make a different, a 8Lb wastegate will open at 8lbs, but a super charger does make a different, there was a guy here with a Vortech and lived in denver, there he was around 8lbs i believe even though he had the same 11lb pulley that everyone else was running around 11psi, when he went down in altitude he did pick up another pound but said he never got down to sea level. Ill try and find his thread on here. id assume its the same as when its colder compared to hotter, the air is more dense so we make more Lbs when its colder..

Ill say you cant go wrong with either, Both my tunes have been good, and ive been in cars with both and they both feel good. I have to see them in person, or spend a ton of time back and forth to fix my minor issues that are more the car then the tune. The customer service from both have been great, bill always emails me back as soon as he can, Mike always picks up his phone when i call. We deal with both regularly, so its hard to point to just one as they both are great to work with. I may point a bit towards Moto-East due to them using a bit more direct injector and with bill i had to up my port injectors, but that's because of my levels and E85, I'm sure bill could've got me covered if i was on the regular pulley and pump gas.

What i would do is call them each or reach out and see which one gels better with you. they both make good tunes with good power. See which one clicks better, It's never a bad thing to have a good relationship with your tuner

moto east for sure

I am not sure, that's why I tagged Airboy in it to see what he says.

Today starts my install, any last minute pointers?

[Derka]

Any tricks on bleeding? Followed the instructions but no fluid out of the "out" port yet. Haven't started the car yet either

I honestly don't know how you guys with the C38 do it. I've got the C30, low boost pulley, and with E85 I'm spinning most of 2nd gear. 1st gear is scary unless I can get it to hook up. And when it does hook up, I'm getting tunnel vision from how fast I'm approaching warp speed.

That said Moto Mike has really dialed in my car. Even on pump gas it feels so much faster than the other 3 tuners have tried on my car.

Next up is the skunk 2 radiator and mishimoto thermostat and I'm ready for the summer heat.

As a potential buyer, you just hit on the reason I would not consider the c38. If I get this kit, it would be the c30 with high boost pulley at most based on feedback from guys like you, @Taino-BRZ, and several others. I realize the power gains of the c38 but as a middle of the road, bump in power buyer I cannot come to terms with the idea that more power than what Taino-BRZ is putting down would require so many other upgrades that go far beyond just clutch and injectors to stick it to the road reliably.

He states he expects to get low 12's or maybe even high 11's out of his setup and I cannot expect the car to hold up very well much past that and I wouldn't think that most people that bought the car could realistically expect to gain much more than that without huge expenses...and at that point you are in a whole different tier of cars that you could/should have bought if you expect reliability.

The kw c30 is at the top of my list.

@post_break what made you choose the Kraftworks kit over Jackson Racing?

I don't like their belt setup. And I got the kraftwerks kit at a discount.

I have a Auto, with over 400hp it spins in 1st.. in fact its useless lol, it spins in second around 4k-4500, in 3rd around 5-6k and depending on the road here in Vegas it will spin 4th above 7k. this is with the 245 toyo proxes 1, not the best tire but still suppose to be a good one, my next set up will be 265 Michelin PSS, i hear they are sticky and have decent mileage. Im also going to get some camber taken out of the back to put more rubber on the road.

until then

I cant imagine what 500+ turbo cars do.. people say this is how the car shouldve come and i disagree. People are putting them in ditches and curbs with 160 hp at the wheel, they dont need 300+ lol. A great tuner here in the 86 world, said 250hp at the wheels is perfect for this car, 300hp is the limit, anything more is just a "manhood" measuring contest. and as much as i spin the tires, and hunt for traction i kinda believe him..
