haha...well its not a new idea but i havent seen it on dsm's... iv seen it on fbodys and such. its like a chip that lets you push the gas to the floor and it will stay at a set rpm. like if you want to launch at 3k. you set it at 3k and it wont rev past that. the other part to my idea is the line lock. i saw that a guy named awoler on dsmtuners already has a line lock that is activated by a button. now what if (if its possible) you use just one button to release the line lock, and use the same button to release the rev limiter. imagine how fast and perfect you could launch. i mean its not that hard to push the break and gas but. it would make it impossible to make a mistake and every launch would be consistant and perfect. all youhave to do is push the gas to the floor. and as soon as the light turns green, you push your button and it will take line lock off and and let you rev. you could launch at the speed ofyour finger! OMG i think this would be sweet...so what do you guys think? :talon:
 
i thought a line lock was for the burn out
now i have to go learn something new
 
maybe i wasnt clear. if you lock all 4 wheels than it can be used as a launching tool. read this

i have a 60-1 turbo and high stall converter so i do things a little different. i switch my boost controlller to low which is always on low 14 psitill i hit the horn(what i have it wired to).then hit the line lock switch and pump the brakes,ease my foot down to the floor and let boost come on to about 3500 rpm and then when the converter starts to flash up to about 4-4500 rpm i kill power to the line locks and hit the horn to hi boost 25 psi and ba-bam! you just left better than a clutch killer manual guy!

now what i was saying was. using his line lock, and the rev limiter button i was talking about that i have seen on domestics. would lead us to a perfect launch. now i dont know if this could work. so it would be best to let somebody who knows their sh*t to answer. but i dont see why it cant work. :confused:

oh ok
i dont know my shit yet trying tho
thanks for the new idea (p.s. im 16 still learning)
 
what you're actually seeing is a transbrake where the car is locked in 1st and reverse at the touch of a button, then upon releaing the button the tranny releases reverse gear. it's just that incorporated with a stutter box. stutter boxes aren't hard to get for our cars, many of the dsm specific ecu modifications have them, it'll be the trans brake that's hard to come by.

is a stutter box the rpm limiter thing? and why would you need a trans brake if youcould just use line lockand stay in 1gear? this is what i found on tuners.com

The line locks are most likely not! and seeing as how you have to run one on each of the line coming from you master cylinder to you proportioning valve,this can pose a little problem.So back to the non-abs parts car i went and took the lines off at the master cylinder and went to the parts store and bought 4 pieces of metric brake line that would screw into the master cylinder and then i bought a inverted flare making tool and the STANDARD inverted flare end fittings that would screw in the line locks and began to TRY to make inverted flares,DO NOT WASTE YOUR TIME or MONEY ON THE TOOL! I ended up after 2days of trying to make good flares and found a shop that makes hyd. hoses and stuff and ended up paying $20 to have the flares made! i spent more on the damn'd tool! i got home screwed the metric ends in the proportioning valve and the other standard ends in the "in" side of the line locks and then screwed the other standard end of the other lines in the "out" side of the locks and into the master cylinder and wired them up to a momentary switch or the rear window defogger switch like i did.... hope this helps ..mods feel free to move if you need to ! i'll to post pics soon
oh yeah and igopoopy, i wasnt trying to insult you dude! i just kinda have a dirty mouth. i was trying to say something mroe like. "lets get some vet's in here" sorry dude.keep learning! im doing as much as possible too! :thumb:
 
while a line lock would work for both lines, the pros use a trans brake. not sure why, but i'm guessing that they would have a reason for you. the line lock is only used for them to do their burnout.
 
Transbrakes actually lock the trans between R & D and with a push of a button just dump everything into gear. Line are more for holding you in the waterbox (FWD RWD) with a quick release. They don't give you any more holding power. Even if it was applied to all 4 wheels. The only thing you can do is add a vaccuum cannister form jegs, summitt, or even crane makes one. It is jsut a reserve that hooks up to the booster line supplying jsut a little more vaccuum for that initial stepping on the brakes.
I have a jegs cannister.....What I do is rev up the motor in N then slam the brakes and wait for the rpms to lower, then i put it into gear, and immediatley brake torque, then i launch like hell.

And just a side note....It took the domestic guys years upon years and huge support to get a transbrake to work finally. I don't think any DSM will ever be likely to see one, unless the motor is turned... :laugh:
 
just heard of these thigns today...Please explain what Transbrake is..i got Line lock down but transbrake plz?
 
look you guys,right now trans brakes for our cars are probly far off from happening, so line locks are the why to go for right now but what ryu wants to do is what is used with a trans brake and the reason for a trans brake is simply because people starting making more torque than the brakes could possibly ever hold.for god sakes i twisted the backing plates off the rear of my old turbo buick! but the awd's have more evenly distribated power and believe me i have no problem holding my 60-1 powered awd at 14psi at 5k so just spend the $130 or so and do what i did and i promise it will do the job for 99% of you guys. now remember i launch at 14psi but right before i let off the line locks i switch to 26psi and leave like hell... :thumb:
 
not to mention line locks are usally used in manual cars(like mustangs)roll when the do there burnout and a trans brake shocks the rest of the drivetrian like the driveshaft and rear end or as in our case the center diff!
 
So how do you get more braking power with the line lock? Isn't it the same as just stomping on the brakes? I just don't see how it helps as far as holding power goes.

I made this post a while ago in this thread and it seemed that nobody really read it.
Jehu, you are right, line locks do not give you anymore braking power than your vacuum is supplying. If you're going to pull through, then you're going to pull through.
Mike
 
I agree with you Mike, I just wanted to see what Awoler's reasoning was :). Who knows, maybe I missed something...
 
maybe they dont,i dont have any guages to srcew into the calipers to found out.but there is a clear difference in my car and the holding power i have now thanks to the line locks.maybe you guys are thinking im just using one to hold the front i guess but i;m using two line locks as explained in a previous post.but seeing as how before the line locks i could not hold my car at 5k against the converter and now i can. i feel that for the money i have invested it is well worth it.you guys my think im f*ing retarded for using them but i've never seen you guys cars and you've never seen mine so do whatever you want i dont care.i know what my car would do before and i know what it does now and the only thing i changed was adding the line locks which in turn made it much easier to launch my car harder more consisently to say the least. so like i said till one of you start making a trans brake i stick with what i know works. so you guys can keep standing on the brake pedal praying to god it holds and you dont roll off and get a sh*tty launch go ahead it dont hurt my feelings at all :thumb:
 
No, I know they work....I have a Hurst line lock on the fronts, BUT WITH a Jegs Vaccuum reserve cannister, which allows me to have more vaccuum build up, creating more braking power. No poking fun intended, just curious as well to see why it would add anymore braking power than just stepping on the brakes.....maybe something funky in your brake pedal itself, maybe you're right and it is locking all fours......dunno....but glad it works.

Why would you say that we think you're retarded? Did I ever suggest that you were? I'm questioning the rationale behind it because I couldn't personally see how it would help...which is why I asked you why you thought it would help. I do agree it would definately make it EASIER to launch, since you only have a button to worry about. But for now, my brake + handbrake method is sufficient for me :).

throw in a sutter box(that IS the rev limiter thingy right?) and link them to the same botton and you got perfect launches! not to mention you cant screw up!this may be something i want to try sometime next year. :thumb:
 
Rev limiters don't work too well with ATs for launching. It interferes with trying to stall the TC.
 
Do you guys have the 1 piston or 2 piston stock calipers?

The double line lock sounds like the best way to get a great 60ft time.
I can only image how slow dropping the E brake is out of the hole.
