Hey Jim. Your mph is looking pretty strong. But man you need to hook up. Like Dark_5.0 said...& I'm speaking from experience here...launching at 5000rpms with slicks and the nitrous on from a dead stop will make you think you strapped a frickin jet to the back of your car! Seriously.
My best 60ft. time with an 8.5in. slick is 1.6. So just imagine the potential your car has once you lower that 60ft. time. Drag radials will improve your times a lot. They are usually good for 3-4 tenths off of your quarter mile. Slicks will knock off more like a half a second. If you do a decent burnout you could probably launch at around 3000-3500rpms with the drag radials and it should hook. I'm still a fan of slicks though. Nothing beats them....or MT Streets. They are basically a slick with a few grooves down the middle. I run drag radials on the street and slicks at the track. It only takes about 10 minutes to jack up the car and swap tires. Let us know what you end up with.
