Nice numbers.

Can you post the dyno plot so we can see the power curve?

with underdrive pulleys you should see less than others since you are turning the SC slower than it was meant to run ( so less air is being pushed )

yes you could get a smaller pulley for the SC ( and i can make it for ya ) but the first thing you should do is lose the underdrives

l8r, John

well now that i hear if i take my under drive tit off ill get more power i will post the dyno sheet in about a week i got 2 get some money so i can got to the tune shop here in sf. but im hiting about 13 psi and the motor dose have cams and ported and polished i didnt even think of putting that stuff on there i didnt think it would have anything to do with the sc but i geuss intake and out take would help alot, the motor seems to be holding up pretty good every once and a while i have to take it in to get timed, and i change the oil every 1500 miles and i will only use 92 octane, and it also has a custom fabricated 3" cold air intake with a K&N deep kone, and to the mt rush trip what days r it on? and i understand abotut u guys wanting to see a dyno sheet it pretty amazing!
