AFR heads or blower?

mustangLX92 · 06-28-2002, 06:58 AM

Would AFR 165's be a good choice for my combo? What kind of gains would I see? My other option would be to get a Vortec A-Trim. What would I need to upgrade for the blower?

Thanks!

You're going to make more power with the A-trim than just adding the AFR's. I would upgrade your fuel pump and injectors. Didn't seem what injectors you run in your sig so I'm assuming it's the stock 19#'s. I would also add a bypass to the A-trim. Depending on your tune, you could make some really good power. Ask over at the Corral, there are many good combo's using the A-trim. A lot of dyno and track numbers. You will be surprised with some of the results. Good luck.

IMO- since you already have the GT40 heads, , I would go with the A-trim.

You already have heads. Forget the A-trim, go with the S-trim!

I agree, you have decent heads. Make th other upgrades necessary for the blower though. HOw is your powerband? That Xcam is pretty damn big.
