Jim D (bowtieman427) and I dodged the rain on Saturday and went to Cedar Falls. My best time last year was 12.13 and this winter I changed gears from 3.42's to 3.73's, which I hoped would get me into the 11's. I spent the day working on my transmission tune, trying to get the car to shift at max rpms' by itself. I got it consistant, but couldn't find the 11's. Five runs were 12.262, 12.252, 12.249, 12.196, 12.196. It was warm and humid so maybe with some better weather I can get there at Rock Falls.
Here's a few videos, I put who it was in the title, because our cars look a lot alike on the track. Until he pulls his wheels off the ground, and me well not so much..
Steve, you gotta be happy with that! Very consistent. Nothing wrong with a low 12 second car at all!

Those are some great numbers, and you beat the Corvette!

My '66 turned 14.14 last fall and I KNOW you have way more engine than me. Mid 13's should easy for you.
Steve, are you going the rock on Saturday ?

happy to get 13.5 then low 13's then get into 12's then 12.5 and low 12's then if i could hit 11.999 and then 11.5 that was my route. had to quite feeding daughter amy for a year to get 11.5 was the only milestone that saved me money. lol

I'm happy with low twelves, but I figured I'd see at least a little gain with my gear change. And, maybe I will if the weather was better.
Nitrous scares me a little. I think if I had stock compression I would try a 100 shot, but I'm about 11.25:1. I've read it doesn't change compression, only cylinder pressure but I can't risk blowing this motor up for a time slip.
Mitch-I was planning on Rock Falls. I've got a couple of things I need to reschedule, but I'm going to try.

I was happy to see a 13.xx number. Once I get stuff a little better dialed in with the tranny shifting, EFI tuning, and now the rear is down I would like to pick up 1/4 second. I owuld love to see 12s but I don't think I have that much to gain, even with slicks.

Yep, I wasn't going to rev it over 6000 to be safe. But 6200 made it go faster, then 6500 isn't that much more, now I've bounced it off the fuel cut-off at 6900 trying to get a little more.
These LS motors like to rev, but not a lot of torque down low. If I was going to make a drag car it would need a lot deeper gears. My 60' times are a terrible 1.8, and I'm only mid 5000's through the traps. Lots of room for gains if I didn't care about being able to still cruise down the road and get 17 mpg.

You'll get there Steve..! Can't beat the consistency though. Time to win some brackets!
