Two recent Bridgeport Builds

Two recent bridgeport builds we did.

The first is  half bridge with aggressive porting of the primary and secondary ports as well as the exhaust ports. The turbo is a Turblown TDX61R. It put down 534whp at 20 psi on E67 (winter ethanol blend). The car is very streetable, even with the bridge.

The second is a full bridge with a Borg-Warner S366. It put down 560whp on c16 at about 20 psi as. This one is set up for the drag strip, but the customer still drives it on the street occasionally. Enjoy!
