Technology Posted May 28, 2010 Report Share Posted May 28, 2010 I recently used this technique to beat a corvette using only 3rd gear instead of starting in second then shifting to third. It's very effective, kindof like a two step for use on the highway. No sudden shocks to the driveline either, since you're already rolling. All you do is get into one gear higher than you might normally start, and hold the brake to keep your speed steady, but floor the loud pedal. But anyway, my turbo sees full boost pretty close to 4000rpm, slightly before and I can get maybe 5psi around 3000rpm just standing on it in a higher gear. I didn't have much time to look since I was driving, but I glanced down and saw closer to 10psi while doing this, a little more than 3K, maybe 3200. So I was able to leave "the line" making boost and no shifting kept me ahead of him the whole time. Doing the 2-3 shift dropped me back and 3rd would catch me up to him. It's always better to stay in front. So I don't know how this will work for insta-boost/stock or small sized turbos, but with larger turbos that lag a bit, this seems to really give an edge.

dmyers151 Posted May 28, 2010 Report Share Posted May 28, 2010 Good bit of info there, I've always been curious about "brake boosting" and wondered if it was just a spoof or ricer gimmick. Link to comment Share on other sites More sharing options...
MiniSRT4 Posted May 28, 2010 Report Share Posted May 28, 2010 Oh yea, brake boosting is def a real thing. Used to do it with my buddies integra with his t3/t04 that lagged like crazy. Nifty trick! Link to comment Share on other sites More sharing options...
Laodicea Posted May 28, 2010 Report Share Posted May 28, 2010 Wait a minute you started in 3rd gear? from a stand still? That is what it sounded like to me by your wording. Please correct me. Link to comment Share on other sites More sharing options...

Please correct me.As I read it, it was from a roll and he tried it initially starting in 2nd gear and fell behind on the 2-3 shift. So they went again, starting in 3rd and brake boosted for the win.

Maxzillian Posted May 30, 2010 Report Share Posted May 30, 2010 Also a darn handy trick for racing a laggy car on the track or in an autocross. I've attempted it a few times before and have to say it takes a lot of skill to manage a car like that in a corner, but the results are amazing!

Technology Posted May 30, 2010 Author Report Share Posted May 30, 2010 Yep, already moving. Fun thing to do, but almost anything is fun in my car. Link to comment Share on other sites More sharing options...
JustPaus_88TSi Posted May 30, 2010 Report Share Posted May 30, 2010 Yep, it's fun on the roll for sure. It's even better from a dig in an auto though, and makes the AWD cars wonder what the heck just happened and why their usual car length or two advantage from a stop didn't materialize.
