    Hello all, I just purchased a new CPR kit with the FI 7683 billet. I was wondering what kind of numbers I am expecting between 93 and E85. I have a fuel system, new injectors, etc. so not entirely looking for a parts list but guidance on what to expect with the 8psi wastegate. I will buy a boost leash in the future, but I am already way over budget, haha. Car has OPG/CG this weekend along with the turbo kit install.
    I was looking at Sai Li for tuning as he is local, although I will be going with the email tune until I can make a 2 hour trip to him.

    You receive your kit yet? I have one on order as well and could not be more anxious. I ordered back in September. I'll be running the same turbo with 93 on 8-8.5# w/ an eBoost2.

    Same turbo as you on 93 made 611/561 on 7.5lbs. I don't have OPGs or feel like replacing the motor anytime soon so I stopped there. Here's the graph and dyno video. I think around 700 would be the limit on e85 but I can't confirm for sure. eboost2 used to control the boost. Good luck on the install, you're going to love this kit.

    Yep, kit is in hand. I have the OPG/CG going in on friday, and then we tackle install saturday-sunday. Hopefully we can finish it in two days. I am running the 8psi spring in the wastegate and being done with it for now. I will run an boost leash later for my 93 to sit at 6psi, but e85 8psi looks pretty safe.

    I'd think 8-9psi would be safe on e85. Post pictures of the install! I normally do my own work but I let a professional handle my install. I wish you the best of luck!

    600's on 93 700s on E85. Obviously dynos all read different so no one can really answer that accurately. Traps would be what I use. As far as the tuning if you have someone local use them. It's a pain with the remote tuning going back and forth and trying to figure things out that would have taken a minute if it was in person. I have a similar setup and run 9psi on E85 and 10.5 psi for track. No pump gas though, I like to give the motor it's best odds.

    I am going with Sai Li for tuning. He is somewhat local (~4 hours), but we are doing remote tuning. I don't mind having to go back and forth to get it locked in. We have to tune 93 first, then move to E85, that which I plan to daily. Unfortunately, there is only 1 E85 pump in Tallahassee, so I will have a few jugs of E85 sitting in the house that I'll rotate in every other week.

    Also, are you using AEM, Boost Leash, Eboost, which boost controller? I was looking at putting the 6 psi spring in and using a boost leash to up my boost for E85, but we'll see.

    I'm kinda wondering the same. I got mine finished up about a month ago and i'm tuning it myself. On 6.5 lbs with only 13 degrees of timing its pretty strong.

    As soon as I can get back to sgmp i'll be throwing some timing at it.

    SGMP is the closest drag strip for me as well.

    Using Eboost2, works very well. Yea getting E85 can be a PIA it's also very unreliable.. rarely does it test above 80 for me, usually 65-75% using Orlando and Daytona stations.

    Went on this weekend, still need to do the fuel kit but then it'll be good to go. OPG/CG went on as well.

    The gate is at 7psi, I have similar mods, and currently sitting at 646hp on 91 and 700hp on E85, thats through restrictive ass gt500 mufflers!

    The gate is actually 7-8psi IIRC, I'll have to hookup another manual boost gauge to make sure. I cannot calibrate this digital one for the life of me. Car runs strong. Sai is a good guy and a good tuner. Can't wait for my E85 dyno tune next month.
