Add another 1/8th mile to it and you run out of gears. So unless you are building a really high revving 2.0L you'll be hitting your rev limit before you reach the traps. I've read where people look for taller tires, etc., to help keep the rpm down.

Those cars are all doing 150-160 in the 1/4 running high 8's No problem shifting into od(4th). Thats why the end clutch is a necessary upgrade. I rev my car to 8500rpm, and if need be I'll rev to 9000rpm on my 2.3. You'll want a bigger displacement motor for the auto just for the shear reason you'll need the lower end tq to get up onto the converter to launch. Most of these auto guys are using nitrous to get on the converter and then shut the nitrous off before they run down the track. I'm hoping to not need the nitrous!!
