Wow, that much huh? I was cruising around running arands this morning in mine and I sat in traffic for a bit, lots of lights, etc. Heat soaked the crap out of the car. It's been 90+ deg here, which I am not sure but may be as hot as I have ever had it out. The car was very, very soft before going in a store and then it was better when I left....for about 5 minutes. I guess it's time to put that Aim Reasearch Dash in so I can monitor all of those temps. And maybe if I'm feeling crazy I could take the massive custom made heat exchanger out of the box and put it on. Nahhhhhh, I think I will let them sit there for another 8 months and complain a lot

How big is the intercooler on your car. Can you get a bigger one in there? I took my bumper and it's supports out and my new exchanger has got to be at least 3 times the size of the stock KB and it's a double pass to boot. I seen on other posts you were using N2O to cool off the intake charge. I'm just wondering if a massive cooler wouldn't do the same thing for you and not have the complexity of the N2O.

Don't know? The motivation for trying the N2O was the extreme heat/humidity. Once that has passed, maybe we will just keep using a 50 shot to help get off the line? The original plan was to just keep upping the boost to around 25 lbs. Then, we're thinking maybe we can keep boost levels down some, by adding N2O. Think it's likely, we will end trying up to a 125 shot (in some combination) with the 20 lbs in cooler drier air, as long as car can hold together. Won't go higher than 75 without another dynotune though. Car is very consistent and quite predictable. Car has five passes at 10.5 and five at 10.6 ET in the summer temps.

Well at the track a bigger ice box can help also. I'm thinking at some point about moving mine to the trunk.....maybe a custom one about the size of a spare tire!

Nitrous and turbo's can make for a mean combination!

Forensic Steve you now have what we call the 1/2acre system going! It seems to make a good bit of difference! You cut a 10.31 on an aborted pass at 12*. You were heading for the 9's with that trap MPH based on that 60'.

I got to get my bottom end installed if I want to keep up!!!
