Background
I have owned the car since approx. 2013. It is self built and tuned and has gone through several iterations. Bolt on 550awhp'ish with a Holset HX40, 790awhp'ish with a T3 PTE 6466. The car had an Eagle/Wiseco combo that made 710awhp in 2014 with the 6466. It's in full street trim other than the removal of AC, AWS, emissions, cruise control and MOST of the interior. It has the leather interior, sunroof, radio, heat and just a downpipe. It weighs 3380lbs with me (I am 210lbs) in current trim with the 17" true street radials and half a tank of gas. I would like to see it get into the 9's eventually in the same trim w/slicks. It is not a race car or a show car...I drive this car occasionally on the street and do take it to the track once in awhile. So, it has made over 700awhp for the majority of my ownership. It recently made 790whp in 2021 with some issues (valve float?) that were later resolved. I had the head rebuilt by DTR.

Quickest time to date is [email protected] on the old setup. This was on wastegate boost on the street radials. Car went 139mph in a higher boost setting on the last setup. Drivetrain issues are always a problem due to its heft and relatively stock drivetrain. I only run it on street radials because it destroys drivetrain parts all the time with the slicks on. No times (dyno or track) on the new setup. Photographs with the gold wheels and JDM bumpers are the most recent. It is my little toy that I built to enjoy and not trying to prove anything to anyone. :)
