Finally got home long enough to race the duster last night at T&T
I was surprised to be having some decent traction issues even with the drag radials. What pressure do you guys run your drag radials at? I run M/T 275 60 r15. Had a minor issue with it breaking up towards the end in 3rd my mph was down a bit from last time I ran it, motor appeared to be getting lean towards the end of the 2nd and 3rd. Never got a good launch spun through 1st gear everytime started getting better when I started dropping the tire pressure so I probably had way to much in there.

Looks good, Kev! I can only see one timeslip - 9.0 @ 80.8. What boost?

That is a skosh faster than my 68 Dart has run on 9.5 psi. I would start at 23 psi for those drag radials and try going down in 2-3 psi increments. I have run around 20 in my Goodyear drag radials, and find that even sticky-ish street tires like around 20 psi for best hookup on my cars.

The other time slip is an 8.9 at same mph, first couple runs were 28psi in the tire and the 8.9 was 20psi in the tires but still spun through 1st gear. My boost is 10psi. I took with plenty of power but it's falling off on the top end again like months ago I sense another monster exhaust leak or boost leak
