I also need to get rid of the air shocks in the azz end as there is no give in the rear so not sure if that would help.....they will be off in a few weeks and hopefully we will be back in Aug.....hopefully I can borrow Andy tires again.....

I actually ran a 13.06 @108 on street tires peddling the car.........figure that one out.....


Ernie and Andys cars are ridiculous.....in a good way

I wonder what Andy and Ernie do, sway bar wise. I've never raced, but have read in the past to loosen them or leave them off???
My buddy had a 72 GTO that was raced from day one, it had front and rear sway bars fully intact with plastic bushings in the end links. This car had some kind of drag race shocks, road like a lumber wagon on the street, mind you this was 1970's technology.

It has been years since I've pulled my front sway bar off..I didn't like the feel of it especially when if I get sideways that was with 375hp in a 13 second car..I may experiment with it a bit...but for now the car leaves very level and smooth...Once I get a proper video I will put one up..My suspension is very simple..just CE 3 way adjustables...90/10 50/50

Yup there also with the new T-2 and Jeffs 4150 custom unit.
Not a good night.
First run blew the tires off and ran a 13:27 115.
Second was a 11:45 121 but with a hesitation. Then the alt belt ate itself and a PS belt got the result. Both out . Had one and Ernie had a spare.
Next 2 runs really bad hesitation from the line....called it.
Spent the aft on the car found a huge vacuum leak. Cant believe i missed it. wanted to crawl under a rock...It was hard to spot .
Everything reset and good to go....runs perfect.
Yes Ernie......i owe you a belt....all good. Still fun with the boys.

Chris- you're knocking on 12's dude!! I assume fuel issue totally gone?

I gotta get into the 12's ......

You're definitely going fast enough. From what I've seen you'll actually MPH a little higher with wheel spin than when you hook up. I think it's because the spinning wheels act like a loose torque converter and allow the engine to stay in a higher RPM band until the car really gets moving.

I bet some simple changes will allow you to hook better. I was getting high 1.6x to low 1.7x 60' times on street tires and running high 12.60s to low 12.70s @ 106-107 MPH with all poly bushed stock suspension and Koni shocks.

For a burnout I smoked them as hard as I could. More heat helped. Dunno if it would be the same with DRs.

Yeah I saw. Few cars there with lower MPH than me with quicker times

Well from what I was told from a friend who watched my burnout said I didn't do it long enough .and perhaps I wasn't in the groove of the track quite right either ...so next time more burnout time......and maybe a better eye....

I've ran several sets of 275/60-15 drag radials (BFG, M/T, and Goodyear) on two different cars, and have a stack of 1.5x 60' times. Tire pressure is typically at 24-25psi.

For the burnout I have one of the sideview mirrors set to where I can see the smoke coming off the tire. When the smoke density turns from "light" to "dense" I ease off the throttle and end the burnout. Goigg any longer is just throwing away tire life. Get them too hot too often and seem like they turn hard and offer less traction. Usually stage somewhere around 2000rpm, then flash the converter a little.

Wow! Congrats to both of you.

Nope like Andy said stuck at work

[Half-Inch Stud]

ta man, those number are real good.

[Torquewar]

Well another great time with Ernie, nice conditions and finally track prep.
CNC was stuck at work but another Pontiac guy with his nice 71 GTO was there with us in the Poncho camp. He runs a 428 stroked runs 11:70s. Die hard Pontiac guy that is another of my resources.
I'm so happy I cant explain. I unloaded the trunk dropped the tire pressure to 18 and that's it. 11:18. No changes from street tune. I actually didn't touch the timing all day.
Played with squirter sizes trying to figure out the bog...next couple runs 11:16 ..11:13
then upped the primary jets .for the 10:9 happy happy. Loaded the car up drove home.
Its nice to have a guy like TA man to push me....hes so darn positive and a good racer.
Thanks for the guidance . We need to get both cars consistant....

What is your combo?

[Torquewar]

Quote]ponhnjon....What is your combo
461 E-Head SD prepped and recently some more enhancements.
OF with Harland Sharps1:65s. T-2 SD with Jeffs 4150 unit.
TH400 3200 Continental 3:42s.
Also to answer 11:16s are a result of carb and intake.....more power everywhere.

[ponjohn]

Getting close to 10's.

What changes netted the 11.16?

More track time,decent air and Andy running 10's!

[Torquewar]

Big thanks to Shaker 455 for a really nice carb.....yes I will call. Theres more in this thing
One change at a time.
TA man needs to try it
