Co2 on the intake
would it harm anything to spray the intake down with CO2 between runs @ autoX, do u think it would make that big of a differance, by intake i mean the whole intake trace including TB/IM

I would NOT do the intake manifold. The quick tempature change between 250+ degrees down to below zero temps could cause it to crack. If you cool the intake manifold first with water to get the temp down, you could then try the CO2, however, I would NOT reccomend doing it to the IM period. The IM can be ceramic coated for about $200, and that would solve the IM heat soak problem.
Yes, you can do this to the intake. When I drag Race, I soak down my intake and intercooler plumbing which is heat wrapped, with water. I then "freeze" the water with the compressed air/CO2. However you must do your run immedeatly after doing this, as engine heat will start to thaw the frozen sections and you will QUICKLY loose the benefit.
My best run with "freezing" is a 15.3 My best run with no freezing is a 15.5.
If you want to cool down the intake manifold, get some of those "blue" freezey packs that people put on injurys. Keep them in a cooler packed with ice. Just before your Run, pack the space between the IM and the Fuel Rail with them. They don't stay cold long in a hot engine compartment, but they do stay cold long enough to last 2 or 3 drag runs.
One of these days I'm going to buy a decent non-contact infrared temp sensor and read the difference before and after runs with the freezey's pack in the IM, vs not having them in there. Just to see if they do any good whatsoever.

random ur best run with the turbo was 15.3?
Yes. 15.3. using heavy 17" wheels and 100% stock suspension....in 90+ degree heat, high winds, blowing sand and 2900 ft. In theory, the car is capable of much faster times, but the track/conditions were ****ty that night. The N/A Tibbies ran a best of 16.7 that night, and the only ITR there did a best of 15.9. The modified mustangs were running between 15 and 15.5, so I was at least competitive with them.random ur best run with the turbo was 15.3?
