The original goal of this car was to hit 800whp and through many setbacks it still hasnt happened. But im getting closer. After playing with the timing some I made exactly 600whp@17psi on our dynojet on pump gas.

Nice,
600rwhp @ 17psi on pump ain't too shabby at all so far....

Whats a quick synopsis of the build again?

Tom

 

Nice!!!

 

Basic rundown on the drivetrain is:

built motor, heads, JWT S7 cams, fuel cell, twin bosch 044 pumps, 1000cc injectors, ATS triple plate, ACPT driveshaft, DSS lvl5 axles, quaife LSD, 3.3 auto rear end, greddy cast manifolds and 20g turbos (these were upgraded from 18g turbos and im questioning if they really are 20g turbos or not), greddy intercooler, custom piping

 

Nice,
Yea if its the same turbo upgrade Randy has, they seemed to run out in like 25psi of boost. You should be able to get right around your goal though.

GL, keep us updated

nice power! Your car is definitely built for more.... I watched it come together here and there. i made 482 on that dj at fastlane maxing out my walbro. 750cc injectors were at 95% dc. i sure hope they got the wideband fixed though.. mark tuned my car on it.. the dyno showed 14's but my gauge pegged at 10... both bad... turns out my wideband was right. A run on a dyno dynamics showed about 8.5:1 afr up top! Hence the 95% dc..
and this is why I'm tuning my new haltech.

edit. I see that it says powerfab all around the dyno.. is that the dyno that's in the fastlane shop or is there one inside of powerfab now? just wondering, i haven't been down there in about a year

 

Yeah we got our own dynojet 224x now

 

What setbacks are you having? Are you trying to hit near 800 with only 17psi? I would assume you still got room left in the turbos

 

Mainly wiring issues from when I let someone else wire the car at another shop before I started working at Powerfab. Now I just do everything myself.

 

more pics of your car...NOW!

 

maybe give up on 800 on 91?

800 on race gas?

600 on pump?

2+ maps?

 

Congrats. Jealous that you have a dyno to play with!!!

 

Did changing the harness fix anything or get rid of the misfire you were having?

If not how did you fix it

 

I ended up replacing my engine harness and ditching the HKS DLI. Then I pulled my EVC6, knockamp, camp2, and standalone out and rewired all those from scratch too.

 

I plan on running a 2nd map for race gas to hit the 800whp that I want. I want to see how far I can get on 93 octane before I do that though.

My IAT's dont budge at 17psi so the turbos still have some room to play with.

 

Good to see you back bro!

 

I'm glad I ended up keeping the car. My friends wouldn't let me give up on it anyways lol.

 

Sick! and love H town too.. my cousin lives there.

 

well considering on their best days, 20hp/psi is normal. So you need 10 more PSI at BEST to hit 800, prolly 12-15 more psi, assume your current 600hp tune is optimal.

Greddy's at 27+psi would be interesting! What's your redline, 8000? RRmedic made 580 at 18psi and then 686 at 25psi (14hp/psi), far cry from 800, but that mostly depends on how much timing.

 

With oxygenated race fuels, you can make up for some efficiency lost in the turbos at higher psi, along with advancing timing thanks to the longer burn time. The latter also applies to methanol/water injection. It will be interesting!
