| being they are called an 'Extreme drag radial", but that obviously was a bit optiimistic. Owell, at least they weren't too pricey. I did detune my mappings for the track considering it was 82 degrees outside and I still have stock intercoolers. The Gainesville Raceway is very strict and I had to wear a helmet. You can't hear detonation for squat and I still had to drive 375 some odd miles back to Georgia so yes, I was a bit conservative. After a few runs I determined that I needed to spend some time getting to know the car a little better at the launch and I focused primarily on my 60' times. I was also running only 21-22psi of boost and slowing inching the timing up a few derees over the hours I was there. Pretty neat to see that 1 degree of timing relates to about 1-2MPH at the top of the track. :) The car was probably producing around 485RWHP at the beginning of the run and likely falling to around 430RWHP by the top end of the track due to heatsoak of the intercoolers. It became apparent that in order to get the car to run a good 60' time, I had to launch at 4500RPM, but that would put so much stress on the clutch that it would slip in 2nd and up. Interestingly, on 2-3 runs where it did slip in 2nd, I let out of the gas a little to let it grab again and it did hold the rest of the track... probably because the power was falling off as the ICs were soaking.. My next mod is going to be the installation of my Aquamist-esque setup. This will help overcome the heat and clean the internals as well.. We (z1) are working on our own sidemount ICs sometime this week/next week and we should have a competitive set of them available on the market shortly - all with some good hard data such as temperature pre/post IC as well as pressures for pre/post IC. I still need to take a MAS unit to a flowbench to generate a map to relate voltage to CFM so that we can build our own efficiency maps for both intercoolers as well as compressors. I'll probably be prototyping these ICs on my car since I have all the electronics to do it and again going to the dyno to see what kind of HP/spoolup differences they make... and then on to the track once more! :) I will be also showing what the aquamist setup does with stock intercoolers and comparing that to larger intercoolers as well to see what the numbers are... I'm almost thinking that the AM will be just as effective if not more in both power gains as well as less money spent, but we'll see the numbers and go from there. :-)
