Default RE: Engine experts - how hot is too hot?

ORIGINAL: M Powered

Strange thing about my engine is when full throttle is applied, it sounds like the rpm is maxed for a few seconds, then all of a sudden its like turbo kicked in and the car REALLY flies.

I'm not all that experienced to be tuning by sound, what should my car sound like? Right now its pretty constant, no stutters or abnormal lopeing.

However, when the car is about to run out of fuel, the rpm picks up and the car moves

Sounds to me like perhaps it is your clutch slipping if the engine is screaming AND THEN the car takes off. Its hard to type out the proper sound but it should be a very high pitched and even sound. If the sound is irregular and your engine ahs a tendancy to suddenly die, your too lean. If it sounds "blubbery" then it is liekly too rich. Tune it so that you can drive a certain straightaway the fastest, then back the high speed needle of about 1/8th a turn. That should be about right.

I get really worried if i am over 270 degrees.
