i have a few tech questions could you help ? car is fine in the turns but spins the tires on the straightaways.would going to the newer 3 degree torque arms and the newer birdcages that raise the rollers up help this problem ? if so would i need to lower my radius rods to make up for the additional bite ? thanks for any info.

We run the 3 degree torque arms on our Bicknell...and everybody is going to them for the dry slick...Ya shouldn't have to change (or I wouldn't initially) the radius rod locations...I say this because we are finding that it's all in the minute changes..Watch your air pressure and stagger as well and the panhard drop helps a ton...It almost sounds like you are running too much gear....I would go up a set, drop your RPM and see if you can keep them hooked up...remember SIPE AND GRIND on those tires(if allowed)

we are running a small block against the big blocks.turning 7500 rpm.i am grinding the tires and using the cam air system [air dryer]air pressure is only increasing 1.5 pounds in each rear tire for feature.stagger gain at end of feature is 1/2 inch.what do you think ? if i back off the gear i think we will not be quick enough.any other ideas.

It really depends on your engine combination...Our 358 just loves to be around 7000-7200....Increasing air pressure increases stagger don't forget..If you are running AR's everyone is running around 14-15lbsRR 3lbs less LR..They say about 5-7 lbs more than the hoosiers/goodyears...Remember this...if you are spinning the tires you aren't as quick either...I would say the one set in gear might be the ticket, you will really be quicker if you keep them hooked up..What track and tires are ya running

10#RR,7#LR,and 9#in both fronts. That's what we were told to run from Troyer.
We run on American Racers,48rr 44lr, and a pair of 33's on the front

They say they have very soft side walls...That you can flop them right over the bead locks

vasques, I need alittle more on your set up to give you some help. I assume you are running Bridgeport Friday nights? Get me some info I'll get you going better. If you can give me the following, Ride heights,sway bar, front coils, rear bars and what the length of the rear arms are, lr wedge, shocks on each corner. That should do it to start.

Hey Wilson,
Now this may be one for you,,,,What about your 750lb adjustable spring bar...It would help a bunch with side and forward bite wouldn't it??

Ok you are close. Shocks are 162-55 on front and 208-72 rear I would assume. Where does the car start breaking the rear wheels lose, from apex out or just the last qtr of turn? I know alot of guys at the Port don,t run a spring bar, do you know how much travel you are getting on the spring bar? The LR rod in top hole will losen the car up on exit as car leans to right it will pull LR fwd. I would set rear rods in middle holes. Next change front shocks to 120-55 left and right these are easy ups and wil help load rear of car. What is your rear %? If those changes help I would also move torque arm to front hole. Short arm gives you fwd bite quicker but doesn't last long. Longer will pickup at apex or just before. Now with the Port being a fast hight momentum I would go to fwd hole.
Well thats is just afew ideas. What number is the car?
