I ran a 12.74 on the WS6 wheels. I switched to the draglites and dropped about 75 pounds off of the car and it only ran about 2 tenths better.

The 295/50/15 radials are very heavy. Even on the draglites they're only about 3 pounds lighter per wheel than the WS6 wheels with tires. The skinnies were about 20 pounds lighter per wheel.

How are you leaving? Do you go off of idle or stall it up?

Off idle then giving it about half throttle til I'm moving good, then hit it. And even then if I got in a hurry it would start spinning.

In the video on the first 2 runs I tried just holding the rpms right above idle and just rolling into it, but I spun and let out then got back in it. On the 7.61 pass I just pulled up and let the light go green before I even put my foot on the gas pedal, then I rolled it to about half throttle for a second and then once it got moving I eased it on down.

On the 7.57 and the 7.61 pass, I could tell right away that they were decent passes just by how much it held me back in the seat.

I wish I was to the point of trying different stall speeds, but I don't know if that is even possible on these tires. There's a local 1/8 mile that usually gets prepped all to hell that would probably hold it but it's closed for while. The crappy track I was at on Saturday just won't cut it.

What did it weigh with you in it on those passes? Just my car weighed in at 3580.

I would say it was around 3500 pounds. Maybe a little less. It weighed 3605 with the stock wheels. The wheels were about 50 pounds and I took about 75 pounds worth of stuff out of the car, but I had more gas in it last time. I wish I had filled it up now, maybe it would have hooked better.

Weld Racing according to a recent video has a new offering that fits our car that requires no grinding, etc... Problem is they aren't at Summit or places like that yet.
