what was your 60 ft???

 

I ran 10-11 psi with my stock 4.8 the only thing it had was my lunati cam 558/558 lift 221/221 dur 114 lsa( For sale). I didnt even have a stall convertor and I was running 13.4's at my local truck. I think my 60' times where 2.1 but Im not for sure. I dont have any pulleys I sold everthing to cammin03.

 

I was using the 3 3/4 for 11 psi and I think the 3.5 will give you 13. If you really want to turn the boost up you can order a pulley from asp its a 3" and that will probley give you 16-17 psi

 

yellow, you bought that ls1 from tennessee auto didnt you?

 

Well the dyno says the power is there, r you pulling a trailer or do u have a fat girlfriend that rides with u down the track????

 

If any thing the truck should be lighter than normal. The front sway bar has been removed, and it has a fiberglass tailgate and rollpan. It has never pulled a trailer and I am single and don't mess with the fat chicks.

 

Weight reduction!

 

seems like your dyno numbers are pretty low for your setup, maybe get those iat's down and run some more timing

 

Sammy~ You should have had Don tune it while you were still up here I think that you want to run that a/f right where yellow said. Also grab a scan tool and see how high your ait's are. Your numbers do seem very low. At 10# my 4.8 with relitivly the same head/cam package and a radix made 430rwhp.

 

QUESTION. What does IAT mean?

(Intake air temps??????)

Thanks.
