Engine is a 427", turbo is a bullseye comp r 83 with a 1.32 ar, basically a modified s480. The down pipe is 5" for about 6" out of the turbo, then necks down to 4" the rest of the way. Engine made 992 on 11#s and 1006 torque on a DTS engine dyno with 92 octane.

I just added a cutout about 18" from my turbo.
Sweet setup!
