[1995MGTS]

I know I'm late to this thread but here's my two cents. A BD-11A Powerdyne is an entry level 800cfm supercharger. It's not meant for boost over 9psi though it looks like a few of you are/were running way beyond that which is awesome. Perhaps upgrading the internal belt/bearings is a good upgrade for longevity. Regardless, it's not in the same league as a 1000cfm/20psi Vortech S-trim. If you want a Powerdyne that can compete with the likes of an S-trim, they do offer the gear driven XB-1. Its capable of 1200cfm/18psi. I used one on my old 1995 Mustang GTS. It had all the bolt-ons (Cobra intake, GT-40 heads, exhaust, Steeda cam, etc) and made 446rwhp/417rwtq SAE(@5800rpm due to spark blowout) untuned. The new owner is having it tuned with the appropriate injectors and I bet will make 470-480rwhp. That's with the XB-1's 9lb pulley, 7" crank pulley, and powerpipe. Thing is, I never came close to pushing the limits of the XB-1 or even coming close to its potential. What's my point? Do it right the first time becuase in the end, you're going to want more boost, gauranteed. You're going to hit the limits of the BD-11A real quick but with an S-trim, XB-1, Novi 2000, etc, they will the ones that will give you room to grow when the need for more boost arrives. Good luck.
