Ok ... This is a 1990 vette with a internally stock L-98 ..... Mods are as follows .... TPIS long tube headers, TPIS 3.5 inch catback, Random Tech highflo cat, TPIS big mouth intake, SLP runners, Ported plenum, 58mm throttle body, TPIS air filter thing.
Injectors are ford motorsport 0280-150-947 24lb per hour at 39.18PSI .. at 43.5 they are said to deliver 25.5 lbs per hour. This car has an adjustable pressure regulator.
So with the mods this car has is 39psi a good base setting for the car or should I drop to say 38psi and make 1lb increments and see what the car likes best.
I've read the whole 22lbs 24lbs L-98 thing till my eyes hurt but in the event this car reall had 22lb injectors are these 24's a better choice considering the mods that are going on this car? How much do these mods affect lean/rich conditions? Due to it being able to breath considerable better would this tend to lean the motor out consierably and will prom programming be required or do any of you know a shelf prom that will be best for the car?
What kind of power gains can be expected with this car? This is a 6 speed car so you dont have to worry about a 700r4 dying LOL ... So tell me what you guys think based on the internals on this engine are still very strong.
