ogradnis Posted September 26, 2007 Share Posted September 26, 2007 I'm about to head out to the strip for my first time tonight. I have a 5eat, stage 2 & meth. I have never really launched my car so I'm wondering how high people are able to rev while braking...without breaking something Obviously I realize the answer depends on a lot of factors so maybe a better question is how high do other auto guys recommend reving?

mccorry Posted September 26, 2007 Share Posted September 26, 2007 Hold the brake down as hard as possible and ease on the throttle till the car starts to creep forward......then let off just a titch. When the last light goes yellow.... let off the brake and mash the gas. (This is called brake torquing) Don't hold it too long like this, though... or you'll cook your transmission fluid.

ogradnis Posted September 26, 2007 Share Posted September 26, 2007 Ok so I should not rev it and hold at 4500 or so like MT guys can before releasing the brake as they would the clutch? Will mashing the gas cause me to bog or will the brake torqueing prevent that? Link to comment Share on other sites More sharing options...
what Posted September 26, 2007 Share Posted September 26, 2007 I kinda dont understand these limited slip 5mt's, I have put one or two, give or take 20-30, black stripes down on pavement and there has always been 2 tire tracks. And I am 99% sure they are coming from the front and not the rear.. But yet going around corners sometimes I can here a wheel spinning, but I stay on the same track. So it seems like one wheel is spinning. But then sometimes I can get both rear wheels loose accelerating around a corner. Doesnt make a whole lot of sense to me. I am sure others understand it though. Link to comment Share on other sites More sharing options...

I do have a tranny cooler and it's because I read all about your tranny issues. So, I have you to thank for my relative success at the track tonight and coming home with a working trans. I did end up brake torqueing (although probably not as high as I could have). Here are there results. Mid-Michigan Motorplex/LGT 5EAT Stage 2 custom tuned + meth/water injection/in car thermometer said 62 degrees F/ 1/4= 13.718 @ 100.82/ 60' = 2.037/ 1/8 = 8.828 This was my first time to the track so I'm pretty happy with the results. I definitely see some room for improvement in that 60' time judging from what so many others have done. Thoughts? Link to comment Share on other sites More sharing options...
AKLGT Posted September 27, 2007 Share Posted September 27, 2007 those are great times! good job! looks like the weather was cooperating with you. and don't push those launches too much. i'm pretty sure they were what lent a big part in my tranny slippage after the STI swap. are you manual shifting or leaving it in sport shift mode? *edit* was going to ask what mods you have to run those numbers, but i see you're running meth too. i want to add that for next year, just don't know if i want to spend the $$$. how do you like your kit and which one do you have?

ogradnis Posted September 27, 2007 Share Posted September 27, 2007 I tried shifting myself but could not do better than sport mode. I really like my kit. I have a coolingmist trunkmount. This was the first time I have really pushed my car since I got the kit installed last spring and I have to say I was amazed. I made 14 runs tonight, the last six of which had zero cool down time in between runs other than the drive back to the staging area. When I finally stopped and popped the hood to cool things down I was stunned to find that my intercooler (stock btw) was not quite icy, but definitely at the temp. of any beer I would drink. It was absolutely cold. After sitting in the lot turned off for about ten minutes I went back over to the car and felt the intercooler again and found that it had heated up quite a bit from the engine heat soaking in. It was quite a testament to the effectiveness of meth/water injection. Link to comment Share on other sites More sharing options...

ogradnis Posted September 28, 2007 Share Posted September 28, 2007 Honestly I wasn't really paying attention to the rpms because I was just trying to watch the lights and get a good fast start. (It's harder than I thought it would be) I just tried to follow mccorry's advice as best as I could (see a few posts above). Link to comment Share on other sites More sharing options...
MarcusDubya77 Posted October 3, 2007 Share Posted October 3, 2007 when y'all brake torque...do you have it in 1st Fake A$$ gear, or sport mode??? I have yet to try it out, since I am afraid of blowing something up... :woowoo:check out the Diamond Gray Metallic Monster!!! Link to comment Share on other sites More sharing options...
AKLGT Posted October 5, 2007 Share Posted October 5, 2007 MD, on your set up, you'll want to manual shift. on the stock turbo, it's better to use the sport shift (what i found). hold the brake HARD. then add gas long enough to get your boost up and the last amber light goes on, move your left foot off the brake and your foot full throttle on the gas! actually my tech showed me how to basically do a full throttle launch, full throttle being as i'm letting off the gas and boosting about 18psi to launch. i thought the car would go boom, but with the tranny cooler and VB upgrade, the car hauls off the line, virtually NO turbo lag. i just have to remember to shift so i don't hit the rev limiter!

AKLGT Posted October 18, 2007 Share Posted October 18, 2007 those are nice times. and nothing like saying you're on all STOCK PARTS with a tune. i bet if you work on that shifting and launch, you should be down to 13.4-13.5. nice to see you also broke 100 mph. never could do that on my gutted pipes an 5EAT.

AKLGT Posted October 18, 2007 Share Posted October 18, 2007 you guys have a track night? i was wondering who the other car was since the times were rather similar. looks like some of the runs i made this year. nice job!

Nutter Posted October 18, 2007 Share Posted October 18, 2007 you guys have a track night? i was wondering who the other car was since the times were rather similar. looks like some of the runs i made this year. nice job! A few of us just wanted to get some runs in before the track close's for the year. Gotta say the Legacy is harder to launch then my old 03 WRX, I could get 1.8 60' all day and every once in a while a 1.7. With the Legacy the tires just dont seem to want to break loose even on the stock RE92's at 40psi ! so the clutch takes the abuse I may give another go next year if I ever swap out my up-pipe for a gutted one (I have one ready just too lazy to install it).

AKLGT Posted October 18, 2007 Share Posted October 18, 2007 ya, those RE92's suck! when i changed to the RE70's this year, i noticed a difference. next year, i'll have some slicks. Wiggle wiggle wiggle wiggle wiggle yeah!!! Link to comment Share on other sites More sharing options...
meier motor sports Posted October 18, 2007 Share Posted October 18, 2007 aklgt... what do you think about short shifting 3rd to 4th. i was shifting from 3rd to 4th at red line. nutter suggested shifting from 3rd to 4th at 6k instead. i tried it but didnt really notice any change. since our stock turbos run outa gas way up in the rpms, is it better to shift early to get into your power band or to stay in it longer and use the extra TQ of the lower gear for a few more rpms? Link to comment Share on other sites More sharing options...
AKLGT Posted October 18, 2007 Share Posted October 18, 2007 i actually stay in 3rd gear all the way through. though i can get a higher trap speed by shifting up, i lose ET due to the time it takes to actually shift and i lose that power band. I'd redline it as much as possible so when you do shift, you continue through your power/torque curves. however, if you wait too long, you'll hit the rev limited and that SUCKS ASS!!! *edit* you have an MT so your shifts might be different, however i don't see how it would change regarding shifting at redline vs below.
