long or short torque arm and why? any problems with madman's torque arm?? why would someone put a short torque arm on there car?
why would they put a longer one on there car?
lift the front end to much? plant tires to hard? not lift the front end up enough? it makes some sense, but yet it still doesn't.
the locals said a few people have had problems with Madmans torque arm (the one i've been looking at) but i can't find anyone complain about em except the 10 bolt guys (since he won't make it for em) but i've got a 9 inch so thats not a problem
car is a track car with maybe 100 miles on it a month in the summer
thanks for any insight

hmm.. i wonder i will want to get a tq arm sooner or later for my cam and nitrous, wonder if shooting for a 1.59 60 requires one, other then a reinforced stocker. also will I be making enuff power to even need one? and what would ya'll reccomend for a cam/150 shot car, and yea i leave on the gas most of the time.

Are you saying that the word "Madman" in and of itself does not generate enough confidence such that you are willing to buy his torque arm without checking it out. (Is that a compound sentence?).

A shorter TQ arm provides 'stronger' leverage to plant the rear axle. Using a longer TQ arm will not allow the twisting of the axle to transfer that leverage to the rear suspension and assist in providing better traction. Think of it in term of holding out a 2x4 that is 5' long with a 20lbs weight at the end and lifting it ... now would you be better able to lift that 20lbs weight if the 2x4 was 3' long (2' shorter)? I think you would.

wouldn't the same principle be put towards loosening a bolt? why would the breaker bar that is a foot longer than the ratchet provide more leverage?

your lookin at it the wrong way slow z28.. its actually opposite. the example with the 2x4, the fulcrum (pivot point) is at the edge of your hand. while with the breaker bar the fulcrum is at the point closest to the nut. so if u can picture the pressure of the brick trying to force your hand down from 5 feet away vs 3 feet youd realize its relatively the same as the force applied to the end of the breaker bar on a nut.. technidick session over.

Look at it from the point of view of the bolt. It can resist the breaker bar if it is shorter. A longer breaker bar will not allow the bolt to resist the leverage. Same deal on a TQ arm suspension, the body having a long TQ will not allow the Axle to twist the suspension in to the ground as easily. Also think of it in terms of trying to lift weights with your arm extended, that is much harder to do than if your arm was closer to your body. That is how the TQ arm functions.

I've talked to a few people about this. I'm sure that there's an expert that can chime in here about it too. The shorter torque arm will "hit" the tires alot harder, and help out the 60 foot alot with a car that's not making a ton of power.. let's say under 500 hp to the tires for the sake of saying. Once you get into the real big power catagory ( 700, 800 or even more to the tires ) you aren't gonna want that short tq arm. The car now has ebough power to "hit" the tires the same with a longer torque arm. If you are still running a short arm with that kind of power... plan on doing a bunch of repairwork..as stated above. The longer torque arm will transfer weight slower, and generally keep the fron tires closer to the track. Slowing down the weight transfer would seem like a bad thing... but with say 1000 RWHP, you don't need it to slam the weight that quick, that kind of power does it on it's own. TQ arm lenth, and what works, really depends alot on the power level that you are at. If you are at the 300 to 500 power level, a short arm is probably a good thing. It will transfer weight in an optimal way for the power level. If you are at the 700+ power level, you'll probably want a longer tq arm. Arm angle also has alot to do with it too.. having the arm straiter also changes the way it "hits" the tires... more angle on the arm, harder it hits the tires, creating more nose lift. If you are at a level say around 600rwhp, a short arm could still be a good option, but you will want to run it at less of a pitch, more level to the ground so there is less lift created.
Don't take my word for this stuff, there's alot of experts that have built 100's of race cars on here that could answer this alot better than I probably have.

The fastest stock suspension car (radial or slick) is Rick Head of Innovative turbo 7.66@ 180+ mph has a BMR extreme torque arm on it and it's a "short" style torque arm,has a best of 1.30 flat 60' on drag radials I believe.The car just barely lifts the front tires and it's gone so yes you can have a very very high horsepower car and still use a short torque arm.....my.02
