3735@110mph says you have around 410fwhp according to my calcs, with 26" tyres you should've been trapping@around 5900rpm. a 28" stiff wall bias slick would bring that down to around 5500 in the traps. I would not go to a radial tyre with a stick. Hope you've got some better parts in that axle than all stock if your really at launching it hard...
