Going to take the duster on the asphalt this weekend. I have some mickey thompson et street drag radials. My question is how much pressure should I run in them? They are not bead locked and temps are supposed to be around 80* and sunny all weekend.

Any other tips are appreciated

17-20 psi, stiffen up your rear shocks, loose on front

IIRC you run a 4spd right? I've heard that DR's don't like manual transmissions.... I run 15 psi at the track with mine and found that it doesn't take much heat to make them stick. I usually get them spining good in 2nd then go to 3rd for a couple seconds and let out. When I first ran them I heated them like a bias ply and spun bad, but a friend suggested a shorter burnout and it worked good for me

How does your rim-width match-up with tread-width ? ... I have heard that they like to be about the same.

I will be running BFG Drag Radials Sunday also. I plan on running 20psi & from what I have read they like short burnouts. I see they do good burnouts in front of your house! See you Sunday.

I just went through this last weekend. Im sure all cars are different but I couldnt get mine to hook up. Everyone on here said 17-20 lbs. It spun terrible with that much air and once they start spinning you might as well lift because they dont recover like a slick. I started talking to other people in staging with some really fast cars and they said 13-14 lbs. Dropped em down to 13.5 and they hooked awsome. My car ran the best 60' ever with a 275 60 e.t. street radial over a 28 14.50 q.t. pro. I would start at 14 and go from there.

I agree totally. These tires dont need much to heat up and they seem to hook better for me with a whimpy burnout. A little smoke is all you need even though I saw some really fast cars doing huge burnouts and still hooking good. My car has 40 year old suspesion and there were probly set up alot better then mine.

Thanks for all the replies guys. It seems there is a wide range of pressures out there. From what I am told we only get 3 qualifing passes. So I gotta figure it out quick. So I think I'm gonna start out around 15 psi and a small burnout.

Bruce, we are leaving tonight so we don't have to get up at 330 in the morn.

Is that a leaf spring car? If it doesnt hook good on the first pass drop it down to 13 and I bet it sticks!What size tires do you have and what size wheels? What dos the car run?

The BFG's suck. Get a set of MT's. 18 psi for me, 1,36 60' times with leafs and mopar drag shocks.

Yeah ss springs right now. Hopefulley ladder before the ice drags.

I'm running 325-50-15 on a 10 inch rim MT et drag radial.

This will be the first time on asphalt with this engine. On ice in the 660 best was 7.049 And 109 mph hoping to drop below 10 but don't think it will happen with this setup.

I think your car will hook no prob with those tires. I ran a 275-60 which only has a 9" tread with junk 40 year old suspesion and ran 1.49 60' with a 10.63 e.t. @125 mph. I dont think you will have any probs hooking unless you are launching it at 6500.

Nope will be leaving off the foot brake. So at most 4k rpm.

I found the Hoosier DR hooks the best, The BFGs are #3 on the big 3 DR scale from feedback on them, they will hook, but if its a stick car it might be tricky. I can vouch that the Hoosier DRs hook "hard", even on crappy track prep in a stick car, With my MTs on my dart they were a bit finiky on the bottle on a so-so prep, I had my extention too tight & they would just skate untill i let off then got back into it, On the 3 sets of MTs i ran in 3 different cars the best pressure was 17 lbs. "cold", anything over 19 was a wash, but every car is different, I'd start with 18 cold & see how it does, & don't need a john force burnout for them to hook, just get them hot quick & pull to the line.
