first i have a hatch with a b18c in it on 17 c2. this is my question; when the temp is around 6of i have massive hose power, but when the temp is around 80f it seem like i loss a lot of hose power. i wanted to know why is this and what can i do about it? i was thinking i could change the air temp sensor or move my timing. right now i have my timing set some what advance.(the ignition is almost all the way to the front. is this my problem? please let me know tx!

 

Heat will decrease performance. However, heat is needed for an engine to run properly, esp. for spark.

I confused on your problem, you feel a huge loss in power when engine is overheating?

 

You have your distro moved all the way to the front of the car? Thats not good cause you're running full advance. Get a timing light and properly set your ignition timing. Pull it back to stock and see what that gets ya!
