Charlie I'm not exactly sure what the convertor will flash to off of the line. To be honest I have never looked because I have always been more concerned with trying to keep the nose pointed in the right direction. Now that the suspension is working better I'll have to try and watch. I am just guessing but I would say upper 5's or so, it doesn't seem that far off to me just by the seat of the pants.
Jon, yes Lenny knows I swapped the tire. I talked with him 2 weeks ago right after our first race. That's the first thing I thought too. I also agree that the 60' times should be in the 1.30's that's what I was expecting. The convertor is a 9" and has a sprag. I'm pretty sure the sprag is fine. I blew one of those up a couple years ago when I tried a friends spare superstock convertor with my last engine. He thought the convertor should be pretty close but wanted me to get the engine dynoed before we change anything.
Boss, I am two stepping at the starting line. Started with 3600 last year with the bigger gears and had to go down to 3000 otherwise it would just completely blow the tires off. Then the 3.73's helped and I could go to 3200. This year is completely different with the suspension help and different tire. I'm up to 4400 and it didn't really change much at all.
I was trying to be conservative with the launch RPM primarily just to try and get the thing off the line. The heads up race that I want to run in limits the tire size (30*13.5 DOT). Right now I have 29*11.5 Hoosiers. I used to run a 28*12.5 M/T. The new hoosiers are a 94.25" circ. vs. the M/T 91.25. both are about 10.5" wide at the tread and the section width of the hoosier is 1/4" wider that the M/T.
JBoz, The engine seems to be pulling good down the track. I am shifting at 6700 and it drops to 58-5900 at the shift and climbs to around 6200 at the 1/8 mile stripe. Once the car is rolling it moves out great. Even the Chevy guys have commented on how the car comes on once its out of the hole.
It just seems getting it to leave it tough. I double checked the brakes, suspension etc. Nothing is froze, or not releasing etc.
Here is a top end video from the first weekend. I launched at 3200 shifted at 6700.
