Bill -
Good to see you out and about!

To answer your question, talk to Verne. He has some basic percentages he has woked with for years that were always reasonably accurate for Stock/SS applications.

Re: Computer e.t. and spped predictions
 

Thanks for the kind words, Dwight. I went to Centerville today, but didn't take the car; too danged HOT!!!!

I'll definitely ask Verne about the programs he uses, when I see him!

Re: Computer e.t. and spped predictions
 

what about the Don Higgins "Crew Chief?" Do we have any users of that program?

Re: Computer e.t. and spped predictions
 

Larry,
Yes.. I have a Mopar bracket racer that uses "Crew Chief" and kicks a lot of BU** in Super Pro on the local level. He is a computer guy and is deadly with it. I helped him with the inital setup and did some follow up when he had a few hick-ups. (He didn't have the car suspension working well) It was easy for me to use.

Re: Computer e.t. and spped predictions
 

Bobby, that is the program I have used to predict quarter-mile times from eighth-mile and 1,000-foot times.

I've never had a chance to verify the accuracy of those quarter-mile predictions (based on the 1/8th mile and 1,000-foot times actually run) and was curious as to how accurate they were.

Has anybody actually done this?

I'm just curious.... My car ran 9.74 @ 106 mph in 1,000 feet. Also, 7.59 @ 96 mph in the eighth. The Wallace program suggested that might equate to an 11.77 @ 116mph in a quarter-mile.

Does that sound reasonable? The car wouldn't hook; spun the tires all the way through 1st gear...

Any comments/advice will be appreciated.

Re: Computer e.t. and spped predictions
 

I know my car is stronger in the first half than in the back half where it runs out of steam.
Last pass I made was 7.94 in the 1/8th and 12.64 in the 1/4th.

The program perdicted that based on my 1/8th mile time, I should have run 12.46 in the 1/4th.

Since we have only 1/8th mile strips around here, and that's all I've worked on with my car,
I believe the predicter is probably pretty spot on.

Re: Computer e.t. and spped predictions
 

Thanks, Bobby. That's the kind of information I need.
