Good runs.. The z28 won 2 races right? And lost the first due to traction?

From what I seen lost 1 won 1. They only had 2 races. The 3rd one it showed was different angle of 2nd race.

Why? From the mods listed in the vid, I would bet that Z28 had less hp and a lot less torque then the Mustang it raced.
I think the Z did one hell of a job.

From a roll the gears really don't matter much. Big cam / big heads I would expect a little more.

I want to hear your logic on how gear ratio doesn't matter from a roll..

No **** lol. That doesn't make any sense. Gears with a cam car will keep you in the powerband better no matter from a stop or from a roll. Especially for a manual.

Well for starters I said gears does'nt matter that much.....not does'nt matter at all. So before you gear homo's get your panties bunched up I'll tell ya.

As some of you know I used to work for a pro rr team. We had a program the you could put you hp/tq figures in to simulate acceleration of the cars. We used Hewland boxes then and could change each gear individually. One day we plugged my numbers in from my car. We did 3.42 vs 4.10 from 0-160 or so. As expected from a stop the 4.10 accelerated better, it's no secret that a gears mutiply tq. You need tq the most when your at a stop to get moving. Both gears got to 150mph in the same time by the simulater......that means that after the car got moving at some point the 3.42 out accelerated the 4.10.

I've changed to a taller gear in my cars 2 times in my life, both times the car went faster than the gear that "everyone" recommended. It should also be known that the shorter the gear the more power it will use and the more heat it will generate. When your splitting hairs to try to make a stock engine with bolt-ons go like I am...this **** matters.

Most drag guys throw gear at it and 28" tires and go racing....and use up some good power doing so.

Also there is another thread on here I pin pointed the guy had to much gear. You can tell by listening to the engine that it was never loaded hard...he was just rowing gears.

Wow your dumb. This guy has a cammed car. The reason gears help so much with a cammed car is because these bigger cams make power at a higher rpm than stock cam. When your car shifts it takes you way out of your powerband with stock gears and a big cam. When you put gears in with the cam, when you shift the rpm's drop much less keeping you in your powerband and keeping you moving much faster than with a smaller gear. You don't want dead spots do you? Take your stupid *** computer generated speed bullshit and throw it out the window cuz I just gave you the FACTS . Gears WILL 100% make the car faster everywhere (except top end maybe) in these 6-speed cars with a bigger cam.

From checkin out your sig you could use a little help in the speed department.....or you can keep buying parts that are'nt getting it done and mail order tunes....and I'm the dumb one. Working on a championship ALMS team teaches NOTHING.
