Ok, time to let secrets out of the bag? And possibly help fellow racers from my experience.
Cal Tracs, as John said, were made for a hard hit. He's right. Talked to him way back and had to throw his settings away. He designed them to go from Stock to Super Stock class and not cut up his Collector car and still run a 9" slick to compete against the bigger tire cars. He did it!!! And sucessfully.
I run the Cal Tracs and Radials. A totally different deal. I have run slicks, ET drags, Drag Radials and just about all forms of pure DOT tires to race.
9.06@150 with a 1.45 60 ft'er.
of course this is with Nitrous in a 3500lb+ street car.
The most important thing you can buy are totally adjustable shocks front and rear. Once I set the bars neutral with a Landrum single spring (you need the soft spring to hook that stiff tire). The shock will be your new tuning aid. Depending on track conditions. Front and rear. And let that front really lift and transfer.
Also found that going to a Glide made all the difference in the world hooking that tire with power. On motor it won't get out of it's own way, but then again I don't care what it runs on motor. It's not a "motor only" car. I was always on the edge with the T-400 and over depending on track conditions and constantly chasing the chassis. Had to pull all the gear out to get it to hook. Went from a 4:10 to a 3:55 to get the car to launch and go faster down the track.
If you start to get a handle on the shocks and add power, then you then need to kill some of the lower gearing or tighten the conveter up to kill the wheel spin at launch. A lot to do and it isn't an overnight thing. I have run the DRAG radials since they came out in the mid 90's.
In the beginning most ccars were in the low 10's to high 9's. That won't get u in a 50 car field today. They are currently running in the low to mid 8's on a stock suspension and a DRAG Radial.
Matter of fact. The same weekend as Norwalk there was a Radial race about an hr away. 15 cars all in the 9's and quicker.
A
Toyota Supra with twin turbos (181 cu.in.) ran in the low 8.40's and heard he has run some 8.20's on BFG's and stock suspension.
And gonna be at Orlando this year.
They're fun, but a lot of work to get them to work with any kind of power. Good luck and if you want e-mail me with what you find and any improvements that you run into with your combo. I'm always takin notes.
