Going to Jotech again this weekend, for the final tune. I'm installing the 12lb springs, so hopefully this will clear up everything. I sent the pics to Tim, hopefully he can post them for me!

What kinda dyno does Jotech have? And are you going to do a race gas tune at all or just pump?

Gonna try and run strictly pump for now. I should be able to make 630 on pump, to 7500-8000rpm. If not, I will back it down to 600rwhp and run race gas on top of that.

Ran into some more problems today. After replacing the 5lb wastegate springs, with 12lb springs, the clutch started to slip at 570rwhp. I really thought, the clutch could support 650rwhp consistently, but its nowhere near it. If anyone is considering the Exedy twin carbon, make sure your not exceeding 550rwhp. I was told, that it would support 650, but I guess they were wrong. Anyways, Jotech recommended the ATS triple disc. So this is what I am going to go with. BTW, 570rwhp was made a 1.1 bar. to 6000rpm and climbing. Anything after that, it wouldnt pull, just slipped .

It really sucks, becuase I havent made an actual pass to redline yet(excpet for low boost). I would have like to see, what kind of numbers it would have made to 7-7500rpm's.

Very impressive build up and numbers. Good to see those numbers on an unsleeved block; awesome. Good luck with the clutch and getting a good pass.

I also recommend the ATS carbon/carbon setup.
I had their Twin and that was holding 550whp OK, and even made it up to 650 before it started slipping (more likely because it was cold and not warmed up completely). Due to my current power goals, I have upgraded to the triple disc and will be breaking in the new clutch disc next weekend.
Good luck bro. I look forward to seeing your next set of 1/4 times.

5.5 psi 380rwhp
10 psi 479rwhp
17 psi 619.6 rwhp
18 psi 639.7 rwhp(power was climbing, but had boost spike at 5500rpm)


There were a couple of minor issues we encountered! Anything above 13-14psi, we started having boost spike. The problem is, the wastegate spring is to soft, for the amount of boost, we're trying to make. I'm going to order 12lb springs next week and have her tuned again. I'll post pics of the tune later today.

BTW, I had a dream last night, that I ran an E55 AMG from Dallas to Houston. We started from a 3rd gear roll, gave him a 3 honk notice and we were off. He pulled about a half a car from the initial start, but quickly put about 3-4 cars on him, by the top of fourth. Mind you, this was at 10psi. Remember, it was just a dream I dont condone street racing, but highway racing is different
Man, you got this car crazy thing going. If I'm dreaming and there's no naked women in it, then its not a dream worth having! LOL

your #'s are really nice man, i'm impressed with the low boost and power you're making. anyways, i have the ATS triple carbon clutch and that thing is GANGSTER!!! it's really nice when i had my 400whp GReddy TT on stock motor, now i have the Brian Crower stroker kit and it's due to get competed a week from today with tuning and everything. Im shooting for the power of around 600whp for now, in the next few months i will be among the 1000whp club!
