Default Rear Mount On A 05 GTO

I have been meaning to post my new setup. I have a 05 gto with a custom rear mount turbo daily driver..

We made 573rwhp & 582tq @ 10psi with only 11 degrees of timing. we still have much more on the table but we stopped there just because we are on the stock bottom end still. I do use the car as my daily driver so i have over 5000 miles of street driving I have been waiting on my new weld wheels and tires I finally got the wheels in after 2 months of waiting. Just have to put the wheels on and get the car to the track now. We did a few passes at lebanon valley dragway on opening day and at 6psi we were trapping 133mph and our best time was 12.01 with a 2.54 60 foot. That was on old drag radials with no tire left on the stock wheel.. Once i find time i will add some videos and hopefully i can find time to make it to the track with new wheels and tires soon.

As blackonblacksls stated below 133mph doesn't look right he is correct I made a honest mistake i trapped 128mph I had to bring out the notebook.

This video was when the car was first tuned. Many addition hours has gone into the tune after this video. This video is about 2 months old..

The air/fuel was 11.3 the smoke was from the additive that we added to the methanol I am back to using 50/50 meth now with no additives.

For the people wanting to know how the car runs with hot weather.. If you are located in northeast area you will know that the pass 3 days we been hitting well over 100 degrees so i decided to put the car for a test. I drove around 400 miles total the pass 3 days and the car acts the same if it were 80 degrees. I haven't had time to take pictures of the setup yet for those that are waiting for the pictures..

You only made 570 on 10psi? But trap 133 on 6psi?

Doesn't add up. Sorry.

That's what the boost gauge said. Like i stated above the car wasn't finished to be honest those old numbers don't mean nothing only my future numbers I am just sharing the result I had that day. We do have a new vac spot for the gauge and isn't as lazy reading boost. Now as far as losing boost i know we lost at least 2-3 psi for sure if i am not mistaking Lebanon valley dragway is 800 feet above sea level..

I should have new results with time slips and logs soon.. I'm not here to be misleading but to share my results and build.

well maybe the whole story is different..

I have been 134mph @10psi and I know it should take right around 600 to 650rwhp depending on weight.. In something the weight of a corvette maybe 550 to 600rwhp but I know your car isn't that light..
