wait for a second opinion but ive been told with the 2.8 upper the biggest you would go with would be the 4lb, so prob the 4lb but id imagine you wouldnt make that much extra power compared to the 2lb with that upper pulley

according to my tuner, greg at RET, you should be well over 500 rwhp especially with you having a ported blower. mine put down 444 rwhp and 440 rwtq with 2.8 upper, idler, and intercooler iced. he said my fuel filter is most likely clogged which kept it from making at least 450.

then he told me if i let him do 2 lb. lower, TB, and plenum, fuel filter he could tune me to at least 500 at the wheels or very close.

have you replaced your fuel filter lately?

no, i'll look into that, one thing i noticed the other day while i was looking the settings on the diablo pred is that timing only showed 10 deg advanced, could it be advanced more with the predator and if so i think running 93 octane 23 deg is achievable, prob that's what hurting me, so a guess estimate, how much power should i see with the addition of a 2 lower vs the 4lb'er?

also 4 lb lower i think i need a diff alternator pulley as well

well the eatons have a lower flow capacity/maximum so i dont know if it would be worth going with a 4 lb. pulley.
but i dont know many specifics about blowers and other people on here do, hopefully theyll speak up soon.

do a search in your area and find a performance/racing shop that deals with stangs and cobras and ask for their advice.

with a 4lb lower pulley you will need a boost a pump
