Small tire blues

bob eaker · 08-07-2023, 07:04 AM

Hello. I’m looking for some advice on what I can do to get my 65 Nova SS to transfer weight and not blow the tires off on a marginal track!
Specs: 65 Nova SS 3050# with driver. 447 sbc, 180 pg, 4.10 gears. Heidts front clip with QA1 shocks. (Single adjustable)
Ladderbar rear with single adjustable.
Hoosier 9/30R-15 drag radials
Neal Chance 5300 w/sprag
I know it’s probably not a legal stocker so I run it in Super Gas but I’m trying to get it to leave like a Stocker on a .400 pro tree.
60’ are 1.40s but if the track isn’t sticky it will literally blow the tires off at the hit. (4800 launch)
Any advise appreciated!

You need to talk to the guy who runs super comp in a 72 nova, with 9 inch tires. Kevin White, I talked to him when he was t&t 8.88 @151 on 9 inch tire, street legal. He is from Indy..

Have you ever run it on bias tires? If so what did it do on them? I've tried radials on my bracket car and on a good track everything is fine, on a marginal track it was hit or miss and when it missed it missed big time. I had a lot less motor than you but a lot more starting line ratio and 10.5 tires.

Good afternoon Bob and to all,
With a Ladder bar car you should be able to wheelstand that car, You might need to loosen the shock adjustments and allow the body to pitch rotate on the tires/suspension. Also put the car on corner scales and find where the weight is and isn't and adjust accordingly. Check your shocks to make sure one or two aren't dead. Pinion angle also plays a part in this as well Hopefully something in here will help you, Good Luck with your adventure.

Respectfully,

Bushing on front? need to be loose. Let shocks do the work. Really needs GOOD double adjustable all the way around.
4 corner weight?

Starting line ratio up to high? IDK. 6to1 is a little better fir small tire

Check out the Mickey Thompson Pro Bracket Radial tire. They are notorious for helping small tire cars to hook extremely well. Completely changed my cars launch consistency. They have cars running in the 8's with these tires.

Also, you need to invest in a set of Santhuff shocks for the front. Well worth the cost, really made a difference on front end travel capabilities of my 67 Camaro. QA1's are limited in their capability. Get a hold of Marty Rinehart, he is a wealth of knowledge when it comes to suspension advise. I use the Mickey Thompson PBR 29.5 x 10.5 tire. 60 ft 1.33-1.35, car runs low 10's @ 129 mph, and hooks great. Now, I did have a problem hooking at Columbus Divisional, but there were several small tire cars spinning. Track prep was non existent in my opinion. Talk to someone at Mickey Thompson about their tire, they are really good to deal with.
