Two recent Bridgeport Builds

Friday, November 14th, 2014

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!

Customer came in with this Audi S4 for a checkup before showing it to a potential buyer. Its always a good idea to have a used car looked over by a professional prior to purchase to ensure there are no major underlying issues.

We Do More Than Just Rotarys

Tuesday, November 5th, 2013

While we get a ton of rotary engine work because that is the niche we have, we are happy to work on all cars. Here is a 1992 GMC Typhoon in for a tuneup, fix a couple issues, and maybe some upgrades. This example only has 70,000 miles, not bad for a 21 year old vehicle.



Second we have a Factory Five Daytona Coupe. Current project is fabricating a new 2.5″ exhaust to replace the current restrictive 2″ pipes.


Just some of the cars we have worked on the past few weeks. Enjoy!
