As much as you can get and still hook. I run 10.53 SLR with 10.5Wx31 tire. Car has 54% on the nose. Mid 1.2x 60ft foot braking. it took awhile but it is pretty consistent.

In a perfect world, you would take a car like yours and reduce the trans gear, and increase the rear gear. Experimentation like this would accelerate the car and help tighten the converter at the stripe. This would pick the car up on both ends as more rear gear doesnt work the converter so hard and allows it to not slip as much. Im sure you know this but just a good example for people to read. Once you get a good SLR that the car likes you play with it, you can keep the SLR but change the trans gear and rear gear. keep the slr the same and change the mechanical advantage at both ends of the track.
My opinion is your car might be faster with less SLR because wheelies are slower than wheels on the ground passes......BUT who am i to say that?>??? LOL
In the end its expensive and a lot of work, but thats how you go real fast
