Steve 'Biggie' Watt and I, Ted 'Penske Ted' Williams, welcome suspension related questions in this forum.

Steve 'Biggie' Watt owns and operates Maxwell Industries. Maxwell Industries manufactures shock dynos and torsion bar dynos. I own and operate TPW Technologies. TPW Technologies provides software to Maxwell Industries to run the machines and provide data to the users. Steve 'Biggie' Watt and I have repaired and valved many shocks and have dyno'd many shocks, springs and shocks.

Post questions, and we will attempt to provide accurate answers.

Sorry about the late reply. Steve and I are mostly involved in non-wing sprints and midgets here on the west coast. I have no experience at the Grove. Feel free to email me at tedwilliams93@aol.com with your baseline that you're running now at the Grove (or, if you have never run the Grove, what you anticipate running).

we just acqiured a set of used 7500 series penske shocks for our operation...do you recommend linear or digressive valving and would this change if the track is rough, smooth, tacky, slick etc. It seems to me visually that the fastest car on any given night, (and this is usually a certain few) seem to have a very very smooth car on rough track surfaces.This lends me too thinking they may be digressive valved. It seems too much left rear rebound would affect this, yet without it the car gets very tight when they start to get over on the right rear. What insight can you give us...we currently run against teams with over a 100 feature wins on the dirt so we are climbing a big hill. ( and loving every minute of it). Thanks for your time. signed "Wheelies on dirt"

What should the spring rate per inch of suspension arm travel/per thousands of an inch of bar diameter rating be for a new 30" sprint torsion bar? Ie: load per 1/1000inch- rating diameter?

 

What I am doing is rating our used bars against a new one based on the load they see for one inch of arm suspension travel in a suspension jig fitted with a scale. Not as good as a bar dyno but it produces consistant results.

Our new .0975 bar / load at 1" arm travel yields a .1222#/thousands of bar diameter. Does this number seem appropriate to use to calculate equavilent rates for the used bars?

 

I've got pictures of our rating jig if you need to see them. I'm at hpcrank@aol.com.

 

Thanks for your time.

On previous post I noted a .0975 bar which was a typo, I ment .9750

 

My bad.

i am working with a 88-40 eagle sprint. I am runn the 305 URSS series. We have to run a 3x5 top wing and weight 1550. Any ideas for a general starting point. We run a traveling series so we run everything from a 1/5 mile to a half mile. most every night we fight a dry slick problem. it very seldom rubbers up. I am getting the dry slick stuff down but cant seem to figure out what to do to keep the car free for the rubbered up race.

Increase stagger in rear as well as air pressure

is there a way to tell how quick a torsion bar goes from high twist back to normal twist?
