87saleen · 08-05-2002, 09:21 PM

i have just finished adding a systemax 1 lower manifold and a set of ported heads from powerheads. big difference from stock. i am running 42# fuel presure , 10 deg timing and .998 v tps with no problems. what are my limits? any tuning info from speed density folks would be appreciated.

No matter what I ever did, 39 psi was allways best. Try changes at the track. Three passes, change, three passes, change....

i will run it back to 39lbs. and try it with the new manifold/heads. its just that i bought this new adjustable regulator and thought it was going to be of some use. the stock regulator was always dead on at 39lbs. and a lot lighter, just not as pretty.
