We worked all thru the day, got the fuel system fixed, water pump and cooling system hooked up, and brakes bled.

Finally got the tune right and took her out for the first drive!!!!!!!!

Video will be uploaded tomorrow. This thing sounds nasty!

Sounds great!

Did you install a manual rack in your car?

I have not, with the skinnys, it is a piece of cake to turn the car while it is moving even the slightest.

Car is off to get the parachute, hood rivets fixed, tablet installed in the dash, shifter solid mounted, and few other odd ends.

Been a while since an update. Pretty busy with doing all the small things like vaccum lines, wastegates setup, cooling system lined out, shifter cable fixed, etc

Finally got around to ACTUALLY tuning the car. Scott clark did the startup and idle. Its pretty dialed in because at the time we had no IAC. That is fixed now. Here are a few videos.


Sorry about this one, friend filmed it on a potato


Car seems to be on 7 cylinders now so I had to cancel the dyno appointment for Wednesday. We are testing each injector and coil tonight and hoping my old tune didn't wash a ring out. My old tune killed an o2 and 16 plugs.......woops

Stay with it, you will get it.....Took me about 6 months of playing with jets, timing, fuel, ect. No dyno here, on the drag strip. Finally got it out and ripped off a 9.63 at 142. Track owner said no more runs until I get the cage updated. Not enough bars. Time for a 25.3 3/4 back half. I could only go up to 3800 on the brake. Any higher and it would blow the DR off at 18 psi on both sides.
Subscribed long term-good luck

I came to the dyno to let Scott Clark tune idle and cruising simulation. He knocked it out so fast we decided to do pulls on my 5psi springs.

Pull 1: 350 hp 360 tq 5k rpms (timing pulled)
Pull 2: 380hp 390 tq 6300 rpms (timing pulled)

Fixed the timing being pulled

Pull 3: 400hp and 410 tq at only 5000 rpms!!!! (Ran out of fuel had to get out)
This thing is gonna make HUGE power when we go to 20 psi and 7k rpms on the 2nd pump.

Thanks to Josh Heitschmidt for the killer experience!!! He jumped on any and all issues like burnt vaccum lines, burnt spark plug wire, coolant leaks, etc with Joseph Meiner and never hesitated. Best experienc ever and only dyno ill ever go to.

What rpm are you expecting to make peak power at? What are you running camshaft wise?

We have the limiter now set at 7k rpms and probably peak power at 6500. Going to spin it to that with more boost next dyno run.

Stock crank. It should take 1k hp no issues.
