    It’s a DNA motoring gt45. Cheapo eBay one. I know they aren’t the most efficient one, but it builds boost pretty well. It would build 8 psi on the trans brake. But I’m running no ignition timing, and the car was really fat on the launch plus I’ve got 3.27s in the car. Will be switching to 3.55s when I change my efi over.

    That's the one I was toying with for mine. Might have to give it more serious thought, sounds like it works pretty well.

    I’m very happy with it. The only down fall I can think of is if you decide to change turbos down the road stuff like the downpipe is unique. I know a lot of the LS guys run this turbo and I figure with their motors being anywhere from a 4.8 to a 6.0 and these turbos working I figured it would be a good size for small block fords also

    I love the look of that intake, it just looks sinister in there!

    Is that a Crown Royal bag as a shifter boot? If so, very cool!

    Small update, got a new hood and a new to me bumper. I also started tuning the holley efi software. Its a learning curve but I can already tell this system is going to be great. I added a flex fuel sensor and added the associated tables for adding fuel for ethanol content percentage, increasing the AFR with higher alcohol content readings, and also adding more timing.
