OP
I was serious about looking into compound boost. Your usage fits perfectly!
see thats just it, i dont want a car that is fast ONLY when the air is right. this bitch needs to run the same day or night. and it was cool last night, 98* for my first run.

driving is not the problem, this is my second cobra been racing for many years. and driving dont explain 571hp. it should be closer to 650+, unless a 2.3 whipple is just alot better than a KB, they can touch 700. my last shot will be a killer chiller or a 50 shot to bring iat temps down, but i feel i should not have to, if the i/c would just do its damn job better.
okay please give me examples of these 700hp and 650hp cobras with pump gas tunes with a kb 2.2 or whipple 2.3
my cobra had a whipple 2.3. and every almost every bolt on possible and made 608/570 on 93octane
My car made 630/650 on 93 octane with a 2.3 whipple, stock motor,manifolds best 1/4 10.20 @138 looking for 9's this winter
Dude if you're as pro of a racer as you say you are, but have never heard of a turbo setup getting heatsoaked, you are crazy.see thats just it, i dont want a car that is fast ONLY when the air is right. this bitch needs to run the same day or night. and it was cool last night, 98* for my first run.

and i am still ready to give up, give up on these stupid heat soaking parasitic drag superchargers and going turbo. :-D never seen a big front mount intercooler get heat soaked.

There is NO chance of making 650+ on 21#s and only 19* of timing... IAT2s in 170 is HOT, so your car is going to be down on power... What kind of fuel are you running?
Ice your junk down between runs, the heat is killing you... You expect to run 130+ when it is 98*'s out side?? Are you kidding me?
Everyone is giving you solid advice, but your only contribution is "no I want to run bikes when its 110 out". Yeah hot lap your turbo car, that'll work better..
You are either a troll, or not nearly as seasoned of a racer that you make yourself out to be.
Dude, you said it was pulling 5* from IAT2s, so you were running 18*s... The total timing the tune wants, and what it gets aren't always the same.. If your IAT2s are 170, then there is no way in hell you are making close to 650.there is a guy making just short of 700 with a whipple 2.3 @ 23psi he is who i was thinking of when i made that comment. i am running 23* of timing not 19. i ran a 240z turbo for years at bandimere, big turbo, 25psi and it would run 116mph day or night, never had a heat soak issue.
i had no idea the KB was such a heat generator, my only solution is to install a killer chiller.
the problem with ice is that it is UPHILL from the staging lanes to the starting line so all that ice becomes a waste idleing in the lanes

138 mph with 630HP in a 6spd IRS cobra? Im sorry to say, but your car is either super light or its on a really fast track in some fall/winter air. If its not the above I listed, please share your secrets.......

Never stated an IRS.Running an SRA. Thats the only weight savings and it was winter. I need to work on my suspension 60 foot was only 1.50 could only launch @3,000 need to be leaving at least 4 to 4,500.

What fuel is the 2.3L Whipple running making that kind of power? Not pump that's for sure.. Most 2.3 Whipples running pump tunes are making mid 500s to a little over 6 at the wheels on average.. You can't compare pump gas and race gas/E85 tunes because you can run a shit ton more timing on race/corn.
What cooling mods do you have? Getting a larger IC reservoir and FILLING it with ICE, while priming the pump will lower your temps regardless of how up hill the staging lanes are..
Even a turbo car with a 100% efficient IC will only lower the temps down to ambient, so yes turbo cars are just as affected by the ambient air temps. A 100% efficient IC is an impossibility.
You need to get temps down, your car running 125 mph in 98* weather is not that bad, neither are you HP numbers considering how high your IAT2 temps were on the dyno.
So getting a killer chiller, or a fogger for your heat exchanger are really your best options for wanting to run in the heat like you are trying to do.

details are always good, especially when this thread wreaks of them. Thanks for the info

I was going to buy a 2.8h cobra from a guy in Monroe, LA and his went 10.7 @ 138 in winter air with an irs and dyno'd like 650 at rwtd.. some people get lucky.
Ok, I'm getting what you did there.. But what else do you have done to support E85? You didn't mention anything else like 80# injectors, or what your pump set up is or anything..okay we have some confusion, i said it was pulling 5* on the dyno, that was with 19* commanded in the tune. we never dynoed with 23*. at the track i installed a 23* tune, i dont know what my iat2 temp is going down the track. i run e-85 which is why i run so much timing.
i want to try putting ice in the i/c res, i just have to figure out how to remove the damn fuel cell like cap. it always has to pried off with a screwdriver, i am scared it will damage the seal.

Sorry about that:shrug:

Are you sure you have enough fuel to support what you are trying to do?? The E85 is going to require a more serious fuel system than gas..
driving has nothing to do with MPH, my shifts need a little work since i have to lift at each shift. but that wont affect the top end much at all
