What is 128 mph really capable of?

I am really stoked that I just trapped 128 mph with my LS1. I was on street tires and couldn't hook with a damn at all. I have a set of hoosiers ready to bolt on and go, and was just wondering if I hooked, what is the car really capable of?

128 mph is fast enough to run 10's.

I'll just say pretty much the only thing stock is the short block.

Already got relocation brackets, hell the entire suspension is aftermarket. So far the 10 bolt is holding up, and it just might with my auto, but if it goes a 12 bolt will take it's place.

To give ya an idea, I've gone 10.69@125.8 w/1.47 60ft so I'd guess you should be able to run just a little quicker if you can leave hard.

HTH,
Steve

Well, u can start prepping that 12-bolt, cuz your gonna be kissing that 10-bolt good bye after running those slicks.

Not necessarily. Autos are much more forgiving on the drivetrain. I had a friend who sprayed off the line to 1.5 60's all day long on the stock 10 bolt. It doesn't matter though, if it goes oh well.

The 7.5 rear will handle the occasional 1.5 60ft. but it will break sooner than later. Ive broken several before switching to the 9in.
