Advice on MT ER Drag versus other types.

Have experimented with air pressure from 11 psi to 20 psi and nearly everywhere in between.
Thanks Chris.

looks like you have lower control arm brakets... what do you have the control arms set at?
im not making near as much torque, but i couldnt hook worth a crap with them at the lowest setting... moved them up a notch and that made a night and day difference.
probably in over my head here

I am really trying to get the car to hook consistently on 26" tires.

I only look at my ET in the 1/8 when I am bracket racing and trying to notice differences between my time trial passes.It was running 11.34 to 11.6X in the 1/4 with considerable wheelspin. I only remember the 11.34 exactly as that was my best ET from the last couple trips to the track. Trap speeds one night were 120 to 121 MPH. The next time out the air was horrible and I was trapping 118.5 to 119.5 MPH.
11.34 was on a 1.62 short time. If you remember from an earlier post in this thread, I pulled a 1.55 on one pass a while back only to have the tranny refuse to do the 1-2 shift and ruined the pass.
It was a 1/2 quart low and that was enough to make it miss a shift under WOT.

Searching for a different tire isn't the necessary, unless you have no reason or desire to run the radial. 468 ain't a big number to not hook those tires either. You will be able to get a slick to hook easier, but don't discount what the DRs can do. I could give you plenty of drag radial class heavy hitters as examples, but I can think of a better one. Search under one of members LS1Queen. Paula has been on the bumper multiple times with DRs.

I agree with you, MT ET DR's should be able to do the job. And I am focused on the tires as the primary problem, thus the purpose of me starting this thread. By the time I got the new motor in, the tires were almost a year old and probably past their prime. I *think* that 26" tires can be made to work, but before I run out and blow another chunk of cash on new tires, I want to gather some input. Tony and I will also most definitely recheck my pinion angle.
I take it from your post that the main thing you think I need is just a fresh pair of MT DR's?
Yikes, 90 passes? They're spent.
Like Tony's suggestion, ET Drags will be easier to hook. I'm 100% confident you could get the DRs to hook though. If you get another set of the DRs make sure you only make one change at a time. Think about trying to hit the tire harder to get it to plant.

Yeah, I'm a cheapskate. When my car was slower I could get away with running a pair of DR's until the very first hint of cord showing through. Only then would I chuck them.

Talking about the 275/50/15 MT DR's.
Tony and I just spoke on the phone. I'm going to call Bill Buck and have him scale the car and see what's going on. Then I'm going to get a fresh pair of tires, still not sure which.
I think the ET Drags will surely hook, but if i want to bracket race the car most classes require DOT tires.

Took the car to Bill Buck Saturday morning and we scaled it and reset the pinion angle. Both the weight distribution and the pinion angle were not optimal and we got them both looking good.
Can't wait to get back to the track. This may have solved my problem. :crossfingers:
