62329, How to flatten power curve?...fun runs out when max boost reached Posted by Semperboost, Dec-17-03 03:10 PM I love the feeling of the car going into boost and reaching it, but when it reaches the max boost the power just drops off. Is there a way to make the power curve less peaky and more broad. I have Joe P MBC (7 psi) so I know that the boost is sticking to the preset level. It's like at 3k-5k is where the power is at but that power band is just too small..I could get a .48 a/r and get a faster spool but it'll hinder at high rpms which I also want. Any thoughts..thanks Alvin 96 RST Star Stage I turbo kit /Starion I/C w/ 2" chrome piping / GReddy Type-S BOV / Missing Link / Custom APEXi- GReddy 2.5" exhaust / 55mm ARD TB/ Nology wires / APEXi EL mech boost gauge / Autometer A/F gauge / Southland Dual Friction clutch

62338, RE: How to flatten power curve?...fun runs out when max boost reached Posted by Justin99RS, Dec-17-03 06:33 PM i have the same issue...even with a stage 2 kit, crane #12 cams and a bunch of other high rpms mods...and at 8psi it still feels like it goes flat once the wastgate is fully open...i know the car is still going fast...but just don't "feel" it once i hit full boost...

62367, RE: How to flatten power curve?...fun runs out when max boost reached Posted by Semperboost, Dec-18-03 11:23 AM I have a 2.5" catback and the Star DP so my exhaust should be sufficient.. I got the 60mm T/B on the way. I need to take it to a dyno to see where the power is at and where it falls off.
