You have got to be kidding. You have never raced before? You have a bad *** car with all the goodies.

My suggestion: take it easy until you learn the car. Get some "seat time" before you step it up. Launch off footbrake at 2000rpm's. Ease into the throttle. Gradually build up your speed. Have someone watch the run/launch. Once you know it launches straight. Step it up gradually. Don't be in a hurry to bust it into the 10's.

You have about everything. -- Your wheels are 17 vice 15's is about the only thing I would change.

Take it easy at first. Practice, practice, practice. You have all the equipment.

i have raced before, when the car had just boltons, 13.4 @ 103 was my best time. I know I really need a trans brake to get the most out of it, but I was just curious about my stall rpm. Shouldn't my rpms be a little higher when I do a brake stand or are the brakes just not strong enough to let it get higher, and what does flashing the converter mean?

what "flashing" the convertor is, means when the car is at idle and you mat the accelerator the convertor will not "hit" or begin pumping fluid until a certain rpm which is where they get the term flashing the convertor i have found the best way to figure your car out is to play with the rpms try off of idle and go to the floor with it, next run take it to 1300 rpm and then smash it next 1500 and so on, compare your 60 foot times and see which works best. the stall is all based around the entire car, how much power it makes, weight, gearing, all play a factor in the stall of the convertor that is part of the problem with off the shelf convertors is for most cars they will work just fine but with a car like yours i would say having one built would be the way to go they will take every aspect of your car into consideration and build it according to that not always perfect the first time but it will be a whole lot closer than the off the shelf convertors. just my opinion hope i helped a little

The only thing I don't see are brakes. I hope you've thought about stopping!

Lets pretend you're going after your license ie stage it, I like the fllashing idea, blast the car out to the 1/8 mile roll out of it. If you don't know where the 1/8 miles is walk the track. Normally there is a little flag. Ask yourself, did the car hook? How did it feel? Flip lanes and do the same thing then look at the results.

The next run put a little motor into the converter, look at the numbers, flip lanes. Same amount of motor. In my opinion have fun, forget the reaction times put all the effort into learning the car. Once you figured the car out, hopefully the same night, go for the full pass if you want based on the information you gained.

You have a nice laundry list of what you've done to your car. Like SS Dave said, I can't believe you haven't run the car. But thanks for taking your racer to the strip not the street for testing - and good luck!!

Most track will just let you blast the hell out of the 1/8 mile. Once you start running full passes the track, for safety reasons - mainly your and the other racers, they will start looking to confirm you and your car are legal
