ET with and without wheelie.

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

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!

This past weekend they were low 1.26 over 3 days. That said, the best ever has been 1.17

Obviously 1.26 and 1.17 is a huge difference within sixty feet. Why and what track was the 1.17?

No wheelie and Atco

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.

I have often wondered about this subject and I always think about Morehead's Camaro because IMHO is the best leaving Super Stock in the sport and is Holt built.

However;

I remember being at the Summernationals at Englishtown when Alderman was driving the Wayne County Daytona and they were bad fast at the time (and that's another story) the car barely lifted the wheels but carried them for over 100' and qualified on the pole. That was one of the most impressive thing I ever seen a race car do.
Now you can say that they were cheaters and you would be right but at the same time those boys knew their stuff.

Doug Battipaglia of Flo Designs who did the heads on the Wayne County car told us they never tested with other Pro Stock teams present. It was all Top Secret as per Chrysler Corp.
Doug didn't do our heads, Bill Ceralli did but Doug provided some speed secrets.

[Frank Castros]

Oh by the way Bill Ceralli is the most talented and skilled machinist ever.

Frank, I have a set of the B-1TS-8 heads done by Doug.. Good heads.
What happened to him.. Lost track of him several years ago

Nick, this discussion nor my comments are about 2500 lb. tube chassis cars which can't be compared to 3500+lb.stock suspension cars nor 3000+ lb. back halved cars. Their "wheelies" as well their wheelie bars are in play for different reasons.

Thank you and I do. My Chevelle was badazz but a totally different car than my Firebird. That said, in all honesty I set the Firebird up in the first few outings of buying it back in October of 2008, after installing my engine, trans, converter and rear gear, I changed the ride height, front coilover springs, shock settings, travel limiters and wheelie bar height.

This photo is from my 2nd weekend out in the car in October of 2008 after licensing with the car the week before.



In 2009 I swapped out the front shocks to Afco's bnc shocks and those same shocks are in place today. From then until the winter of 2022, when the front and rear suspensions were rebuilt as a part of updating and freshening this car from front to rear and top to bottom

the car has been run with the same suspension settings other than adjusting the front shock extension on race day. The car as I run it today is about 200 lbs. heavier than when I bought 16 years ago and has far more power under the hood than when it was raced in Super Stock or when I bracket raced it footbraking.
