Default NA LT1 9.81 @ 138.2 **Updated 11-8-15

I broke into the single digits last pass of the night. Very very happy with how quickly this car is getting dialed in! I couldnt hook the first couple passes, made a couple suspension tweaks and dropped the tire PSI and it started hooking.

Here is the pass before the 9.97 pass..


And the slip..






Motor is a 383 13.2:1, 23* LE Trickflows, LE ported Victor EFI, custom solid roller, GZ vac pump. 4L60e and a Ultimate Converter Concepts 5800 stall -that needs loosened up a bit.

Ive got around 12 passes on the new build and have already hit my end of the year goal. Now the question is how deep can I go?

** 9-6-15**
Got some new personal bests tonight.. No changes to the tune just getting the car sorted out. It's leaving really nice now..

Should have a video up of the 9.82 pass later today.

DA was around 1600 ft




**11-8-15**

Last passes of the year.. no new best ET The band in my 4l60e is slipping when trying to engage. I am commanding 1-2 1500 RPM before I need it to. At the top of 1st gear, the computer has not seen RPM drop for the 1-2 shift so it commands the shift to 3rd - it engages 2nd briefly and bumps 3rd.

DA was 500 - 600 ft..

That is flying! You just bumped me down a spot. 135.01mph is good for another tenth or two easy.

Thanks guys! The car continues to impress me every time I take it out. Small changes are paying off big,

The car weighs 3200 to 3300 with me in it. I will scale it at some point, but that is my best guess for now. Still have all glass in it, stock kmember, stock front suspension aside from coil overs. I took a lot of weight out, but added some in also.

Congratulations! Very nice. Lt1 in the 9s on muscle, impressive to say the least.
I want to say you have a very nice top end combo by Lloyd Elliott thats definitely putting down some serious power.

All lies. Tell everyone it has a 200 shot on it! I'd like to see some passes in some cool mine shaft air. That thing is going to move.

Send me the new data logs so I can check them out .

Congrats !

Thanks fellas!

Bolo - Lloyd does some really nice work! He is under rated for sure. I have a really great machinist too and that helps a lot! The bores are round and everything is right on. Specced a camshaft for the motor that pulls right up to 7500 where I shift.

NewOrleans... the car made 477 rwhp on a rich base tune. It was a low reading Mustang dyno with RPM graphed from wheel speed. I will probably get it back on the dyno to see where Im at end of the season.

Kyle - shhhhhh
