Coan boost converter It was mated up to a Turbo 400, 408ci twin 66 mm turbos. I ran 8.23 , 1.29 60' Car weighed 3450 lbs. No problem making boost even on the foot brake. It also drove great on the street! $450.00

I didn't run it with a mid plate but did have a ultral bell on the trans. The converter is 2yrs old but VERY limited use! I'm upping the power a bit and going a different route. Like I said I could foot brake the car to 1.35 60'. On the trans brake I had to use the launch control to keep the boost down. I could still drive the car on the hwy no problem.

Damn! I've been searching these forums for the last 3 weeks looking for a converter like this but I've been searching th400, not turbo 400 
I would have paid your asking and drove 10 minutes to pick it up Ah, I'm pissed! If the sale falls through, let me know.
