Re: Radial tire question
 

Thanks, Mike. I've never had that. I have a low hp car that always just dead hooks.

Re: Radial tire question
 

This is low hp as well around 750hp, with aim to dip in the 5's 1/8 N/A 23 sbc @3250 pds 10 x 28 bias tire. New combo just for fun, no particular class in mind. We kinda stumbled on using the wheelspeed to our advantage, first time we took it out went 6.01 on a set of ten year old tires. A lot of wheelspeed w /no wheelstand. Took it from there using shock adjustments favorable for wheelspeed on new tires to keep the car off the bumper no wheely bars.

Thing about radials on a stick car, stick cars usually need to turn the tires a little at launch. Radials don't "recover" like bias slicks. I was with a friend who had a fast Pro Stock car, when he decided to try to make radials work. Last I asked him about it, he never made them work. When radials spin, from what I have seen, they spin. Bias tires I have had recover much better.

FWIW,a few years ago a friend was running a 305 stocker stick car.I let him try my Hoosier 9x30 radials.Had them at 15-16 psi.I run 20-22 on my auto.Made 2 runs hooked on both,picked up just under a tenth and almost 1 mph over his M/T bias.The track had good bite that day. gsa612

When I did try this a few years ago, I had to run them down to 10-12 PSI, they didn't work at all at the normal 20 PSI range that the auto trans guys seem to run. Interestingly, I picked up nothing as far as ET goes which surprised me.

Re: Radial tire question
 

Not a stick guy but good reading and learning. Back in the 70s I would go to the track with a good friend who had a 64 Vette M/P 277 cu in. They had to spin the tires (14x32) at 10,000 + rpm or it would stand on the bumper. Not too much science in clutches back then. I imagine a dead hook with radials would rattle teeth and pull your eyes back around your head, and very hard on parts.

Re: Radial tire question
 

You would think at that low psi it would drive the rim into the ground making the tire oval,then unload on extension with the radial sidewall.You may have to change launch rpm and clutch settings and tighten the shocks for less "hit' to get it off the line clean.It would be more of a challenge on a higher HP combo. gsa612

Someone will bridge the gap. They always do. It's essential-intrinsic.

Re: Radial tire question
 

Mike, not bashing your product but have you checked with NHRA about the legality of this for Stock & SS? The reason I ask is that I proposed something similar to this quite some time ago and was told absolutely not. They said that anything that affected the release of the clutch linkage would not be legal. I think their issue is that this kinda gets into the delay box gray area. Jim

By-product- ramification of rolling up sleeves unambiguously, possibly. Unless new tire technology solves the equation. Although once that happens, it's no longer an advantage, dominion.

If you're referring to me.
