Clutch should have a harder time in the beginning.

Sounds a lot like my car... it just doesn't perform at the track. Icing the S/C is cool and all... but it's your coolant that gets those IAT's down. What you need to do is run the A/C on full blast when you aren't racing. Make a pass... as soon as you are down the 1/4... turn on the A/C (Coldest Setting/Highest Fan)... When you go to park your car... let it sit and idle for a while. In the staging lanes, leave it running with the A/C on... don't turn off the A/C until after the burn out when you are getting ready to take off.

What the A/C will do is activate the fans, which will chill your Coolant out. Helped me out a lot.

There is more to racing that just a damn 1/4mile, alot of cars can run the 1/4 fast but suck ass from a roll or on the twisties.

I love my car.

That is the worst advice I have heard in a long time. I'm not trying to be rude but running the AC will do nothing but make the car have to work harder. Its working to cool of the car in the inside. If anything its best to shut off all lights, all air flow into the car. Trust me, I did not trap 100mph stock because I don't know about drag racing. When temps start to rise turn off the car in the staging lane. Pop that hood and let it cool off. It would be much better to set up a switch in the car to turn on the fan.

I know it sounds silly, but have you tried disabling the boost bypass valve? I've felt stock SS/SCs lose power for the last few hundred rpms because the car starts to bleed off excess boost. That could give you the symptoms you are seeing, and I have seen it to be random, not all cars do it with just an intake, but I've seen it happen to a stock car with air-box mod only. Just somethign to check.

^ That is a good idea. Mine never showed symptoms of this but some cars do in fact act this way. He may even see full boost quicker. In the case of my LSJ I always seen full boost right as I stepped on it in first gear. Never had a problem hitting 12.5 psi in all gears in stock form. Now I hit around 16.5psi on stage II pulley.

oh god please dont sit in the staging lanes with the car running.
sitting there regardless if the fans are on or not will have the engine heatsoaked by the time its your turn.

and yeah, water dripping on the track will get you an ass kicking at any decent track.

run the A/C on the way back to the staging lanes, and when you get there shut the car off.
dont start the car every 2 minutes to move 10 feet. get out and push it.
the best thing to do is the IC/FAN relay bypass mod,
so that your IC pump and fans are on with the car OFF in the staging lanes.

He is absolutely correct, though. It ABSOLUTELY cools the engine. how? i do not know, some secondary fans kick in somewhere. The car will go from 214 degrees to 183 degrees in 2 minutes. It will keep your engine at 183 when you sit in traffic. sit in traffic and look at your coolant temp rise past 220. this car heats up pretty high without that a/c on! Try it. Opening the hood doesnt do that much, in my opinion.

The reason turning the AC on cools the motor is because the default setting for the motor fan with the AC on is ON.

Turning the heat on does take heat away from the motor. That's why when your car is starting to over heart, you are supposed to turn the heat on with the fan at the highest setting.

i was about to say turn on the heat... it always drops my coolant temps and i did it at the track but i was at 120 when i started up to move towards the starting line and back at 188 when i was gettin ready to stage so if u can get quickly from ooling off to staged then u should be better with around 150-160ish maybe. idk if thatll help ur prob but it may be worth a try since im not the only one to say something about it
