Comella has his stuff in one sock as we say down South. BIG wheel speed and he pulls 2nd by the tree with the front up about a foot. He wins every race right there. I am sure he test and like I said "it's in one sock". Former Phish

Congrats to him

Glenn,
I did and thought that it was one of the best. didn't think the front wheels were that high off the track.

They weren't, I wonder why

Looks like they know what this bracket racer has been stating here.

Most of the fast ones were a foot and a half off the ground. A lot different than prior years.

Thats going to vary from car/truck to car/truck Its not simple physics at all you also have to consider air drag of the front end versus air drag of the bottom of the car, front wheel drag versus none(during wheelie) offset by wheelie bar wheel drag(if the car has wheelie bars)

In the case of my 10.4-10.60 something truck(which is set up with a 9 inch tire ie stocker build), with no wind, the bigger the wheelie the quicker it is, when it goes into fly and be free mode, its flashing the convertor higher, which reduces the 60 foot on the rear tire time and lands 100-125 feet out there. Good sanhuffs keep it from a bouncing too much. It goes 100% straight every time.....except for TOO big of a wheelie, which will torque steer it a touch onto 1 tire, etc and kill a couple in ET as its going snake like down the track.

There used to be a rule of thumb out there I think maybe in the MP books, something like 10 flat and less more wheelie would be slower due to aero drag, with modern stuff, I think you could get away with 9.30's

Testing, Testing and more Testing to see what works best with your combination.
Too many different combinations with different variables to say one thing works best.

With my Chevy II if we tied it down it would lose .10 loosing it back up to do huge wheelstands it would pick that .10 right back up. Just my experience.

This is preposterous!!!! Didn't you read what 1320 said!?!?!?

[1320racer]

As usual you add nothing of relevance to a thread, you’re a clown!

Now what is preposterous is some here believe that a car can break the 60 foot beams just as quick with the back tires as it can with the front tires!

Back in 2005 we ran TS with Jerry Haas built car. We experimented with wheelie bar settings. We found that the car liked 5" height for wheelie bars, our car was pretty consistent tripping 60' clocks at 1.02 with back tires. We went to 4" on bars the car slowed to 1.04, we went to 6" on bars and car hit the bars too hard and unloaded chassis. We went back to 5" and the car went right back to 1.02 tripping with back tires.

Every car is different, you have to find that sweet spot in every car no matter how fast or slow.

Ed you guys have found the sweet spot with the Firebird. Car leaves flawless every pass, your chevelle was awesome to watch and was consistent. But you had to spend the time with it to find what it wanted, shocks & settings, travel limiters or non, rear suspension settings, etc..

Make 1 small change, keep good notes or read your data acquisition.
