Hi all, Recently we took our hotrod back to New Zealand from Australia to compete at a Nostalgia Drag meet. Because we dont have a roll cage or parachute, I was told that 11.0sec was the quickest we could go and that I had to run a radial tyre. I have never run Drag Radial before, always run a 28" x 9" slick. So I purchased a set of MT ET Street R 275x60x15 Drag Radials. I had also changed to a set of Viking dual adjustable coil overs in the rear. Knowing that changing 2 things at once is never a good idea, I was forced too. So the track itself isnt world class like im familiar with in Sydney Dragway (Australia), but it seemed ok. I used to run 14psi in the slicks and was advised to run approx 6psi more in the radials. I also stiffened up the compression to start with. Turns out I didnt change the tyre pressure because it seemed ok. So my first run was **** off the line with bogging, so we dropped the float levels and WOW it hooked hard but not as high as it normally does. I was only running to half track (1/8mile) and getting on the brakes, which the commentator had fun with. We kept introducing more compression in the shocks, 2 clicks at a time and we ended up PBing all increments to half track. 60ft - 1.37sec (old 1.46sec) No Transbrake just footbrake to 2200rpm 1/8 - 6.150 @ 112mph (old 6.43 @ 112mph) These were achieved with a 3.25:1 diff gear too. Car weighs 3400lbs. Extremely happy with the results. My goal with our car is to get into the 5sec over 1/8mile and we arent too far off considering we picked up 3 tenths. We are converted to the Drag Radials for sure!! Wont be racing again till October and yes I will put the 4.11:1 diff gears in it.
