N00b question... How fast could this spin...and work?

Any clue as to what the GM FWD sport compact drag car is running?

Which one, There are a few. However the ECOtec ones are using a modified HD4T65E,

If they are using a manual in some of them then It would likely be the new style Getrag (which bends shift forks in an instant) The new SS 2.0L supercharged Cobalts use a heavier duty 5spd Getrag, So possibly this one IF they are using a manual in some of the cars. But I know for sure that the sponsored GM cars are using the Auto.

ya the borg warner 5 speed rocks, u can shift as hard as u can pull it and and rpm, wayover 8000

If it is RWD and a manual it is probabally a Lenco Style so they do not have to clutch the beast. But as far as I know there is no Lenco style trans for a FWD application

$$ could fix his issues, And these problems can be sorted out, But he's not interested and say's he's just going to street drive the car from now on I guess.

Actually my biggest fear is sinking 1000-1400 into a differential that will last, replacing/working on all the syncros so they will shift only too have the output or input shaft shear and ruin the thousands I just spent too build up a tranny. Also, cost effictiveness is an issue. For the cost of building a manual too take the abuse (probably several thousand bucks including a differential), I could buy a RWD Chasis (Say an Opel GT), a tranny and maybe even a rear end too put my motor into.

Don't get me wrong, I love my car, but breaking it all the time is no fun either.

Here's something on par with a Lenco. No planetaries. Uses airshifting:

Quaife, Xtrac, and Hewland and others make sequential fwd racing boxes for touring cars, and one of these guys make them for some drag racing classes.

aluminum rods (i wouldnt take steel rods that high)

Why in the fuck would you rev aluminum rods higher than steel ones? Is there something I am missing here besides ignorance?

[Will'sFiero]

"no 60 degree will rev that high and stay togethor. "

Did you ignore that the 3.6 VVT built by GM for racing goes past 10k? Sure, its twin turbo but its a 60V6.

Umm... it also shares absolutely no parts with the traditional 60 degree V6 (now the "high value" V6, as opposed to the VVT, which is the "high feature" V6).

Aluminum rods are always used for high rpm and high horsepower engines. Our funny car uses forged aluminum H-Beam rods.

[eliteweapons]

Some people don't think about weight in a rotating mass and the multipliers at higher rpms.

[TurboZ24]

Aluminum Rods tend too stretch and I've never seen a manufacturer recommend them for any street/endurance application.

[SappySE107]

Yeah, they don't last as long but they are excellent for limited use engines. If you plan to pull the rods out and replace them more often, aluminum is the way to go. Not practical for street use.

[geoffinbc]

How long are LS7 Rods?

[Fiero11]

Heavy Duty 5spd Getrag? Does anyone know what ratios, and final drives are available?

[Guest]

aluminum rods yes are for racing applications.

But if you just gotta have them,....
