If I forgot anything I'm sorry. Thanks for the help. One of my questions is what should I do for a underdrive pulley? How much horsepower yall think I'll be making ? should I delete my maf ? Thanks for the help guys

My buddy did close to the same set up but with a bigger cam and he put 500 to the wheels

Hey Dustin did he have to flycut the pistons to run a bigger cam ?

dustind6327

No he didn't I can't remeber exact what heads he put in them but he didn't have to do that but every motor and car is diffrent for some strange reason

What percent underdrive pulley you guys running also what brand? And as far as a maf cab I delete it or would it be better to run a maf?

Sounds like a really stout combo...with as much power as you should be making I wouldn't **** around with trying to find 5 more by slowing down all the acccesories. Charging system and cooling are more important IMO.
It seems that those who do speed density either ARE or know someone who can tune the hell out of a combo. I'm unsure of before and after(MAF delete) but it would seem to remove a slight restriction....I'd bet you'll be in the 480-490 range.

Thanks. If I did delete the maf would it make it harder on the tuner?

Saturday night bump for more info help and opinions....

A good tuner will tune the car in speed density and with the maf...so in both cases the tune will match. Shouldnt be any harder on him either wsy.

I've got the 25% Powerbond on mine. No issues whatsoever. The OEM one broke so I got a case of the "might as well".
