ok thanks Danny
I'm going to {try and}determine whether I'm getting an accurate finish line reading from the Biondo Box. I see it has a play back feature, hopefully the data isn't lost once the power is off. This would give me "when" the engine hit the peak rpm.
would it seem reasonable that if the trans/converter is slipping I could still have a good and constant ET and MPH?

I think Danny is right i had a 8' converter in my car and it would go 5,400 on the brake i was running NOS and went up to a 330 shot and the car would only run 6.18 at 114 and i got a 10' converter made for the car it would go 5,200 on the brake but it would lock up and i went down to a 150 shot and the cars 1st past a 5,96 at 119 to 6.04 at 118 my converter would slip in high gear my motor was a 446 in a 3,220 lbs DUSTER i am building a 572 all motor no NOS i hope it will run 5.70 class my car will weight 3,120 and my converter will be fixed for the motor i run a 727 with pro brake , and i went to a 456 gear i had 488 in it with 31 x 10.5w slicks and i will be on alcohol . Good luck to you .
