Right now I already have a twin 62mm BBK installed. I'm throwing on the S-Trim very soon and was wondering if this would hurt performance as I've heard bad things about many aftermarket TB's on Cobras. Suggestions?
I've heard lots of bad stories about the BBK tb's, especially the 65mm tb. Thats b/c no-one gets the upper manifold ported to fit the new tbs, and they cause a loss in hp. I'd keep the BBK and get your upper manifold ported to match the throttle body. You should be fine. However, a single blade, frpp or accufab will flow more in the supercharged application, maybe 5rwhp or so better than that bbk.
