the small 60mm exhaust wheel also helps me spin it too, but I could prolly spool a 80mm exhaust wheel just as easily being front mount.

e85 is fine at that temp, i ran it up at 250* iat, dont worry about it.

how much timing did you end up pulling out for such high IATs?

Cruising around town I see about 25 degrees over ambient (usually sits around 70-85 right now).

At the end of a pull at the strip it creeps up to about 145. Highest I have seen it was 160 and that was hot lapping a few laps.

i think i had it on 15 or 16*, its e85, the temp at the valve is probably 50* cooler once the fuel hits it, at 10psi id run it all day.

Its kinda hard to see in this screen shot, but with my hot air Kenne Bell super charger on 17psi, this run started at 130* Iat, climbed to 240* though the run, maintained 20-21 degrees of timing with only a couple tiny hits of KR... :jest: I would NOT recommend this! :jest: But it something I did on a mixture of 25% e85 and 91 pump gas ;)

Not true, my camaro runs on E85. 250* intake temp went the same ET as 120* intake temp. E85 doesnt care much about intake temps, its alcohol.:burnout:

We installed a RX Super Chiller Sta on a 03 Escalade with 18# boost....left running 30* IAT2's lower than he arrived with. Kep the IAT 2's in the 70-80* F on the return trip. Where he would run 120-150 he was running 30-50* F below w/super chiller.

Also had another just below 700 hp at the dyno then Gainsville drag strip and here are his results:

I also ran at the track last week and 1st pass 95* out was chiller off and going through the Maggie Heat Exchanger IATs started at 105* and ended at 160* run was 11.70 @ 118mph, next pass turned on chiller for 5 minutes and cooled it down still 95* out IATs started at 64* and ended at 115* and the run was 11.25 @ 124mph. So the chiller did its job and kept IATs down and the car pulled no timing and I was able to make my fastest pass yet in the middle of summer no less. 6 mph is a big jump and I lifted because it was a bracket race so should have been 126+mph.

What kind of fuel was this on? I noticed a good gain in power aswell with lower iats when I was on pump gas, but now on e85 it seems like it dont really care, 105 out on my home and the thing seems to rip just as hard, I notice slower turbo spool in the heat but once she wines up it pulls.

here is some good information, my supercharged corvette, just installed a procharger, no intercooler just methonal injection, 6psi of boost, intake temps start at 100* and end at 91*, i am spraying alot of meth though. one nozzle in the intake of the blower and one after.

stock fuel pump, stock injectors, bought the blower and built the bracket, i have 500 bucks in the entire setup
