Wondering what cam would be best for supercharged application.
This is what I have...
SRP 4.030 Pistons
Eagle H-Beams
Eagle Forged 383 Crank
AFR 210cc LT4 Head
Comp Cams 224/230 112 Lobe Sep. - Running for N/A
Pro Magnum 1.6 Rockers
Ported LT4 Intake
Monoblade Throttle Body
Racetronix Fuel Pump and Harness Upgrade


A D1-SC is going on this winter...I've heard that changing the lobe separation etc. is good. Pistons will be changed to give me somewhere around 9.0:1 . Wondering if lift and duration should change. Planning on running 12-14# of boost. I can build a N/A motor...but first experience with forced induction. Hopefully someone has some tips on picking a cam. Still would like to keep the wet kit in the car...however change the pills for a 50 shot. Anyone getting away with the stock fuel lines with the racetronix kit...or am I gonna have to upgrade. They don't really give you any numbers on how much that pump can handle. Any experience with ATI's would be greatly appriciated...

 

I think stock fuel lines will be fine. I have the Racetronix dual pump on a 15# D1 and 72# injectors.

 

I only have the upgraded in-tank fuel pump and the harness...you think that's gonna cut it? Or do you think I'll have to put a booster pump farther upstream...

 

A4 is that an automatic? Then we need more info.. Are you running a stall? What type of lifters are you running.. Are you wanting to switch? Solid Roller? Hydraulic Roller? Just plain Hydraulic? I like Crower Cams.. Some like Isky, some like comp cams, some like crane cams.. Could show you some great crower cams.. I just recently purchased my cam from Crower..

built my motor for S/C even though I don't have one.. ( Didn't want to rebuild again so I just went for it on the first try...)

 

This cam off Combination's website looks like a good streetable hydraulic roller cam that would work well with your blower:
227/239 duration, .560"/.577", 114lsa

 

I'm running Comp Cams Comp R hydraulic roller lifters, and a 2800 stall T/C. The car isn't set up for drag at all...just looking for a streetable cam with good midrange and high end. It's more or less to hand some rich dude his butt in his 80,000 Viper. Yes...it's a 4L60-E that's probably gonna puke it's guts out even though it's upgraded.

230/236...not what I had in mind...
