Finally found someone to set up my chassis. Bringing it Tuesday to set pinion angle, adjust 4 link, set front / rear shocks and whatever else is needed. Question is: Can a tune help my et / mph?

Anything you do to help the 60' will pay off big on et. MPH not as much affected by 60' as et is.

chassis tuning definetly helps with e.t. not so much mph but it helps with e.t. if your car 60 fts good now wait til they tune it a tad and youll see improvements for sure thing is i hope they are doing this at a track cause all tracks are different its better to tune at a track cause this is where the car lives not strapped to a dyno or on floor jacks :yes:

i dont know how experience you are but you should have them mark your 4 link brackets were each hole is and measure the instant center on each one and write you a cheat sheet of what each position should do. this will help you down the road for tuning at different tracks, ect. then keep a log book of weather conditions you had and what bar settings you used. it is very helpfull down the road if you change anything. and hot roders always changed stuff

Question, Why spend so much time getting a pinion angle to within a gnats a**, when as soon as you adjust a ladder bar up or down, all that goes out the window? Is the pinion angle more to do with driveline integrity, or traction? Thanks.
When you make a laddar bar adjustment you have to re-check the pinion angle and re-adjust, you can not make the adjustments and expect things to last very long. The pinon angle has to do with the whole car working and performing properly for countless passes down the track.

You will only see positive results if your car is currently setup incorrectly...There's no magical 4 link/ladder bar/shock/pinion angle etc. setting that makes you go fast. Every car is different.

So, if you have a ladder bar set-up and a cross link bar which is the best way to install the cross link for performance..Driver side to right rear or passenger side to left rear...

For a street car would you recommend a wishbone set up or keep the cross link bar set up..Let us know how you like your chassie set up once tuned....The pro's and con's of a profession set up over trial and error...

i'm gonna guess ..

the best set up will be the one that puts the least amount of loading on the chassis from the rear axle to plant the tires enough so not to spin so it can push the car foreward instead, JMO

Tried the car Wednesday night (after getting the chassis set). The times didn't change, but the car works, transfers weight, the front lifts, and rear squats. I'm satisfied. The front shocks were "bottomed out", so the car was launching, leaving like a boat with the motor trimmed all the way down. BUT NOW I HAVE ANOTHER PROBLEM. Please help b4 I go out and spend all kind of money (getting tired of that)! My engine location has changed from stock, which makes the radiator fill cap lower than the intake, because of this, I installed a thermostat housing with a fill neck, in order to fill the coolant from the highest point of the system. The overflow bottle is filling, when temp gets into the engine. I bought a new cap, but never installed yet, thinking that I have a bad cap, which is allowing coolant to enter the overflow can. I've seen in catalogs, a recovery tank which allows air to be continuously purged and the coolant recycle from the tank back to the radiator. I;m thinking of changing the cap, trying it out, hopefully this helps.
