How do I knock off that extra tenth?
I ran a 10.13 a few weeks back. So now I need to knock off that tenth and be in the 9s.
Any suggestions? I'm switching to 28" slick. Theyre hand me downs. I can afford new anything.
My 60' sucked. Was only doing 1.61s. Last year it was 1.50s. I took out some weight since last year. Added Viking coilovers and a mwc dragbar. I would think the car should pull 1.40s on motor.

1/10th would put you at 10.03! jk What gear tire combo do you have now and at what weight? Playing with coilovers could help taht 1.6 60' is deffinatly an area that could be improved. I'm sure you know 1/10 at 10.00's is a lot harder than 1/10th at 13.00's! I see your running NO2, a little more never hurts!!

For shock settings the best thing to do is film the car launching and them watch the suspension move as it launches. It's amazing how much a tire will flatten and your rear end will move in slow motion as well as the amount of movement in the front end. It all happens so fast it's hard to do in real time just by watching and impossible to do from the driver seat. It will also help to make sure your ARB is loaded correctly. You could use an online calculator to determine trap speed/rpm if you switch to 28's, depending on your peak power they might help or hurt you.

3.73S and 28s with nitrous with around 7000 rpm cap sshould net a 140 mph trap give or take depending on the converter slippage
Going from 26s to.28s will loosen that converter a bit
You made a good move going to 28s with the spray
The extra sidewall will help but like i.told you, your rear shocks are very important.
Hope you get your 9 sec pass!
If it doesn't hook up, id play with tire psi Then start playing wirh the progressive.

If the shocks are soft in the rear on the compression and allows the body to squat on the axle, it very well might .
If youre on a budget id suggest comp engineering 3 ways. There dirt cheap and have been in the 1.3 sixties on radials. Granted it'd be nice to see ya on a double adjustable but if your hell bent on saving money try them. Mine went 1.42 on the comps on radials,
