what gears for highway pulls.............
what gears for highway pulls............. No drag track near me and not into anyway...........nuff said there.
So, I'll have right around 800 RWHP with my sprayed 441ci.
Whats the best ratio and strongest brand of gears to get for 50-160mph runs?
I have 3:73's now........but lots of people are saying I should go higher. I'm not at all worried about losing low end torque because no matter what ratio gears I get I'm certain the tires will roast from a dig anyway with a big ole 441ci.
Whatcha all think......????

Unless there's a better stall ration for what I want to do with the car?
***I doubt a built 4L60E would stay together after just one hit of 800 RWHP..... lol Would be cool to try though.***

6800 rpm/315-35-17
not including 4th/OD
mph in 1st/2nd/3rd
3.73=45/86/139
3.23=53/99/161
3.08=55/104/169
2.73=62/117/190
I have to assume those figures would be with a locked convertor as an unlocked convertor(due to stall/slippage/blow-thru) would not see those mph figures.

Drag wouldn't play a part assuming the torque converter is locked. Unlocked you would see higher rpm than the gear calculator at a given mph.

Verdad Gallardo Or is that another type of calculator all together where HP and drag is entered also?
I see that the calculator here is simply figuring if the engine is spinning at x and the through the drivetrain x rpm's are put to the tires.........then the car will be moving across the ground at a given speed.
But is there a calculator out there that does it all....drag and HP included? Thats the only way I see a speed calculator to really be accurate, right?

I was just thinking, if drag "and horsepower" isn't taken into effect with all other data entered, then how can it really tell if the car will even make those speeds?

Coefficient of drag for a fourth gen looks to be .320-.340, whatever calculator you find would need to take that into account.
Yeah, that calculator is talking purely mechanical ability or potential, if you have enough hp to actually do those speeds is completely separate. I think there are some calculators out there for calculating top speeds with given hp, but i don't know of one offhand to recommend. May google "land speed calculator" or something like that.
