So a lot has been finished with very little pictures.
Wiring is done besides some custom switches. Hobbs switch is wired up and my fuel pump is pretty loud. Moving some serious fuel.

The car cranks, has fuel, and spark. I can keep it running by spraying fuel in the intake. This tells me things are working well and I just need a better tune since the car WILL run once in closed loop. Initial start up in open loop is just to lean.

Gauges are in. All work except the fuel sensor but I think my lever got bent on install.




Then I got the tires out after putting on the rear bumper and wheel wells.





And the car stood on its own for the first time in 20 months

I would like to know more about that billet rear. Is it steel or aluminum and does it use the same factory components inside?

Is not billet just 12bolt aluminum. Added probably 15lbs to the car if not more. It is a very nice piece but pricy

Needs more gauges. Looks good.
Is going to really look good with the wheels and paint color when clean. Good choice.

Tune session #2 had the car see 4000rpm and a little bit of boost then my muffler threw fiberglass faeries everywhere. getting that resolved and heading back on Sunday. It is a busy time for sure. Thing sounds mean as hell even at that low of rpm.

I love how it sounds when you start it! Are you going with the same paint scheme or doing something else?

Close to the same. New hood scheme will change the front and new rear spoiler but beyond that the same.

Car runs pretty damn good.
Got the car exhaust hacked up as I still had cats and my mufflers shot.

Vid: Car made 700rwhp/600rwtq spinning to 6500rpm. Made around 17lbs of boost.

It is a very fun car and the rpm wraps out very quickly in 1st-3rd.
Plans are already in the works for more power...

Made it to the Texas Mile where I learned I cannot shift worth a crap from 3rd to 4th. Pulling straight back was making the car go to 2nd so I was having a big delay in that shift as I had to pull to the right but not so far as to go into 6th.

First run: 97mph @1/4, 14Xmph@1/2, 151mph@mile. This was a proving run that needed to be between 140-165. Did not shift out of 4th.

Second run: 105mph@1/4, 144mph@1/2, 188.9mph@mile.
FWIW most cars hitting 14X in the half were doing 160's. My tuner thinks at the current power I could do mid-high 190s.

At the end of the run I had an issue. The cause could be a c clip holding a spindle in busting, brakes dragging, or the fact that my fuel pump died and killed the engine. All that I know is it was a wild ride and I can't wait until next year.

I think you could use a little rear downforce
