Message	As the engine starts flowing large volumes of air at high boost pressure, the compressor wheel heats the incoming air due to friction. So you start flowing more air, but it's too hot which causes a loss of HP. T-25's too small to flow a lot of boost on an engine like the vg30 -Josh Email- TwinTurboJosh@hotmail.com AIM- JAMChitlen "that and if you can still smell it on your fingers three days later despite frequent washings" - sbsTT(MD) 12:42:45 11/13/02 "Computer games don`t affect kids; I mean if Pac-Man affected us as kids, we`d all be running around in darkened rooms, munching magic pills and listening to repetitive electronic music" - Spokesman for Nintendo, Inc., 1989 "You're gettin' ready to blow?
