I made 522/488 through a t-5 and a very mild tune on 12psi. Only with Gt40x heads and b cam. Your car would probably be close to 500rwhp with that setup on 12psi. And 1/4 times with that setup should easily do mid high 10's at 125-130mph

Everything has been great so far with the WG and BOV. Held steady boost on the dyno. I've put 200+ miles on the setup since tuned and everything is still good.

I can see if I can dig up any pics of inside the fenderwell. I cant take any now because I have the liners back in and they are a PITA to take in and out with all the wiring in the fender.
I know that the pipes arent perfectly lined up, one is cocked slightly

Thanks, Just bought a used c-4 setup with what i thought was a 10" dynamic converter called them up and they recommended a 9" to stall what yours does. The one i bought is suppose to stall 3500, plus they dont recommend using a 10" convertor with a transbrake. My setup is a little different to where i am using gt-40 p heads, also going to use the stock cam.

Yeah, well it took a little wrestling to make it work. Had to enlarge the inner fender hole to let the discharge move towards the firewall. It was definatley the worst part of the install followed by fitting the innercooler behind the nose.
