Running the Northwest Drag Tour. Drove down to Woodburn, OR today and ran three times in 100+ degree heat. IATs were above 120 at one point! Car ran 11.922, 11.927, 11.934 with a best MPH of 118.12. My 60' wasn't that great at 1.8x, but it was consistent and didn't spin at all. I tried flooring it from idle to try to hit the tires harder but that screwed with the computer and it didn't go into PE and didn't add fuel like it should have. I think with the traction at the line it went into an area of the VE Map that wasn't tuned before, so I richened that up. I will see if that fixes it at Portland tomorrow evening. Car really needs a 4000+ stall converter. Maybe this winter I will get a triple clutch billet.

Today at Portland I had a 11.80, 11.75, 12.75(nevermind this) and an 11.78, all at about 118.4mph. The air was better, and I managed to get a 1.78 60'. But, the car simply won't launch any harder than that with the 3200 stall. Never broke the tires loose once, hooked hard and scooted! The new MT ET Street R tires are great!

Off to Bremerton in the morning for three more runs and then eliminations!

Best pass at Bremerton. I'm 5012. Left lane was the twin-turbo Mustang that won the event. He only ran half track...

Oh, and can it baby? Yes, yes it can.

I think the car hooks ok.

So, there you have it. A daily driven N/A LS swap Cutlass that currently runs mid-11s but should be in the 10s by the end of the summer. I will keep this updated as I get quicker. Next up is a Circle D triple clutch 4200rpm billet converter and a set of 2" to 1-7/8" stepped Hedman headers.

Pretty sure I've only been on Ls1Tech, YellowBullet and Bangshift. But I figured I needed to land on a g-body specific website eventually. After-all...I have parts to sell now!

Ok, may have been LS1 tech then. 🙂
