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.

My wife and I had a good weekend at the track..bought a cheap RV a while back and trailered the car down..ran Friday night stayed overnight and ran again Saturday..Friday night I wasn't thinking I was going to run..there was a light drizzle on the way and it didn't look too good..We arrived picked a beauty spot under a big old willow tree..they were dragging and prepping the track...I figured what the hell havent ran the car for a while..lets see how it performs..it was actually drizzling when I was driving up to tech..After tech I asked how is the track..a guy with a 9 second car told me no worries!..1st pass was the best of the night resulting in a 11.22 at 121.60 with a best ever 1.6240 60ft..next pass 11.2519 at 121.69 with a 1.6301 60ft..last pass upped the jetting spun hard ran 11.5280 at 120.95 with a 1.8210 60ft...called it a night ...track was getting greasy..


Saturday...first 2 passes spun..11.3837/121/1.737 11.3612/120.91/1.7639...dropped jetting 4 numbers front and back to test..3rd pass slop on start line..11.4612/121.53/1.7610..last pass and new best.........11.1692 with a 122.24



Meanwhile Andy (Torquewar) was there too!His first pass was 11.18!He spent time between several runs fine tuning the carb....and the result was his best on the last pass!



10.99............................................. .................................................. .................................................. .................................................. ..................................Congrats Andy!

This has been a long time coming!

You guys' did great!

I'm glad my new Hi-Flow unit worked well for Andy & hope you try it.

Congrats!
Jeff

Install 3.42 gears and an overdrive trans.
Mileage would be excellent.

Easy 10s with more cam.

I used to drive it there all the time...but we like camping overnight too..so pulling it with a RV makes sense..

The car gets decent mileage actually with the 3.08's..and settles into a nice purr at 60 to 70mph...

I've reached my goals for this year..quite easily and cheap..a new intake with a great port job by Pontiac Derek..and dropping the tailpipes..After watching Andy I have a sense of what I want to do and change on the car...stock appearing sleeper cars have always caught my eye...Andy's car other than the rims looks stock on the outside....mine doesn't fiberglass hood,smoothed door handles..this winter I want to put a stock ta hood back on,start making it more sedate and stock looking..also a few other cosmetic changes...I think Andy and I could blow minds with 2 stock appearing street driven Trans Ams running low 11's and dipping into the 10's
