View Full Version : Wedge The Wedge Shop Single Turbo TR7V8 build

04-06-2012, 09:10 AM
As some of you may know, or not know, I am have been in the process of building a Single Turbo Rover V8 setup for my 1977 TR7 FHC.

The motor will be a stock rebuilt 3.5 Rover with std compression (8:1) which is ideal for the turbo application. I will be using Cometic head gaskets,in which the heads have been shaved down to accommodate the extra thickness of these gaskets. Erson cams has designed a special grind pattern for the application that will be suited for the turbo application with power from 2500-6500. A Holley 750 blow thru carb will be made specifically for my setup. The Holley will sit on top of a Harcourt single plane intake manifold. The setup will be intercooled with 2.5in piping.

The transmission will be a stock rebuilt Rover trans LT77. The car already has The Wedge Shop Mustang rear end conversion and all the other goodies.

I will update the thread over time with my progress. I plan on making the turbo setup into a kit in which anyone can bolt on their stock 3.5 with no modification and push 250Hp to the wheels.

Here are some more specs on the setup.

Some quick vids of it running.

Car still has some bugs to work out, currently is running great on 10psi at half throttle, but is having some issues at full throttle. Will try to sort it out in the next two weeks.

I saw it two weeks ago when I picked up a new stat for my TR8. It looks really good.

Nice work Clint!!

Finally got the car running correctly. Had to change out the carb hat and for the time being cut a hole in the hood.... Not my first choice, but had to get it to The Roadster Factory show and not having a hood that closes was not an option.

Here is a quick 3rd 4th gear pull. Car runs strong and am expecting 275-325whp when I get it back to the dyno.
