After H/C/I, what supercharger?

91notchbk · Jun 6, 2007

I installed AFR 165 (61cc) heads, Comp XE270 HR14 cam, and Edelbrock Performer intake. I want to install a mild supercharger but do not want to split the block because the bottom end is stock rebuilt. I am around 300 rwhp and would like to be around 400 or so. What supercharger and supporting parts do you guys suggest?

Get ready to spend some dough lol. You can go with a Vortech S-trim. It's what I'm running on my stock short block. Bigger fuel pump, bigger injectors (unless you want to run an FMU) and a custom tune (big bucks right there). Also at 400rwhp you might want to baby that T5 or kaboom!
Also don't think you'll be safe at 400rwhp. It is potentially block splitting range.

Ok, so an S-trim. What fuel pump, injectors? FMU with 24lb or 30lb?

This is an S-trim with 6psi.

How about a 255lph, 30lb injectors and a FMU? The reason I like 30lb injectors is because I can get a set for cheap. Otherwise if 30lb are too small then probably 42lb?

I have 42 lbs in my 96 Cobra with 8psi and no FMU. I have a 255lph in tank pump, and another 255lph inline pump. HP in sig. Pump gas 92-93 octane.

I once had a 95 GT with a GT40 aluminum heads, stock cam, GT40 intake, 65mm t-body, P-600B Procharger 3 core intercooler running 11lbs of boost. That car had 24lbs and an FMU. I have a friend with a stock motor, no FMU but the same supercharger set up and he runs 36lbs.

See what I am getting at? Every car is different, and I would leave that up to you local tuner/dyno guy. I would say at least 24lbs with an FMU, and 30 or 36 with no FMU.

Ok clear as mud. I do not want to get the car tuned right after the install I may go to a tweecer and tune it myself. I am just trying to find what I should start with.

After H/C/I, what supercharger?
