I want to do some brake torque. How do you do it? Does it hurt the engine or tranny? Will it cause tire to spin? Will it be fat?

OldGuy

I assume you mean downshifting with the SS. It won't hurt the car or the engine. The computer will prevent you from over reving the engine. It won't downshift until the car is at an acceptable speed. Keep in mind though that the RPM limit is high so you can down shift to second gear at highway speeds. The tires won't squeal but it is like hitting the brake hard. If you have ever driven a standard shift, it is basically the same thing without the clutch. You get to learn the best downshift speeds for each gear. The only difference is that it is more difficult to match engine RPM with the next lower gear to make the down shift smooth. I have not been able to time it right yet but I'll get there.

To Brake-Torque, hold the car by apply light(just enough to hold the car from moving)brake, and gradually apply more gas, move to the desire RPM, and hold it there....

AS soon as you are ready to launch the car, let go of the brake, and slam the gas pedal ALL THE WAY DOWN!! Timing is the key here, get it right, and you should see some improvement in 0-60 time...

will it hurt the tranny?

AKRY

It sure will put a bit more stress on the tranny, so, try NOT to do it on a daily basis. But once is a while is ok, I guess...

Also, usually ppl brake-torque the car at relatively low rpm(below 3000 RPM, not sure about Japanese Cars, however, my 400SE's best Brake-Torque RPM is around 1600 RPM), therefore, shouldn't have to worry if only done so occasionally..

It's not necessarily the transmission as much as the torque converter that overheats (beyond it's normal temp. range) when you brake torque. However, as AKRY stated, it really shouldn't do any damange, just make sure you're transmission is broken in beyond the 600 miles mark -- that's my bit of advice.

The peak range for the TL-S is probably anywhere past 3500 rpms when the car delivers it's peak, broad torque band -- or if you wanna go higher, my buddy always launched his Integra GS-R at 4000+, beyond the beginning range of the VTEC.

Thnx for the additional info, PeterUbers.

To find the best rev for Brake-Torque, you really have to play with it a bit try have the rpm as close to peak torque as possible, or close to "Sweet Spot" as possible...

What about the brakes... any real damage or extra wear on the pads or rotors?

Only do it for a second or two - it causes tremendous heat in the torque converter.

I would not recommend it as you will see only a marginal improvement. This was more a factor in the old days when there was primitve ignition timing technology . Brake torqueing advanced the timing to give more torque out of the hole. In today's cars it is much leff beneficial, if at all.

I'd rather do this sort of thing to YOUR car than mine.

It's simply not a smart thing to be doing to your own vehicle.

Honestly,

If you're looking for the key to a better launch, I think it's less in the brake-torquing and more in putting $$ into new, sticky tires like Dunlops or Pirellis. I hear Toyo makes a great tire that'll fit the stock rim 17x6.5", however, it does run over $150.00 (from the website i checked, www.tirerack.com)

I'm being picky here, but since all Integra GS-R's are manuals, you can't be talking about brake torquing correct? You mean revving it to 4000 RPM and then lifting the clutch quickly right?

Acuraboy --

Yup -- definitely talkin' about the manual tranny. He beat that GS-R into the ground, and it still came back asking for more. I don't even think he replaced the clutch in over 50,000 miles drivin' VERY hard. He had DC Sport headers, CAI, and a comptech exhaust kit on it. That thing was very quick.
