GTO30272

I am looking to run this in my MN12 turbo car in order to help build boost off the line. Does anyone have a picture of a button or something installed? I want to use this only for building boost on the launch with my MN12. I was under the impression that I could have a button on the steering wheel that I would hold at the line, floor the gas which would be limited to the set rpm, then release the clutch and the button to lauch. Is this correct?

Also, I am planning on swapping to an auto over the winter and was wondering if you would need a 2 step with a trans brake since I would think the trans brake would allow you to build boost, but I hear many people still run the 2 step even with a t-brake.

Thanks in advance.

We have one on the GTO and its on the clutch switch so When the clutch is pressed in it activates the 2 step and once you let out the clutch your off.

If you did that, then wouldn't you have to have the clutch pedal fully pressed in to have it work? Usually I dont have it all the way in when I launch. Also, wouldnt that then activate it each gear change? Thanks for your help.

We have switch on it also and no it does not have to be all the way in just a little bit. We use it on the shift so we can keep the foot to the floor and not loose boost on the shift.

Hellbent, I have one on the way to me. I was wondering how it does building boost on the gto you mentioned? What size turbo? What rpm do you limit too, how much timing do you pull, and most importantly, does it build boost on the line with the clutch in? How much in how long?

Oh, the switch is at the top of the pedal so , no it doesnt have to be all the way in, just barely depressed.

Mine is setup on my transbrake.

Its a S374 BEP unit with a 1.1 a/r backside, no timing pulled just run it up to 5500 on the 2 step for about 2-3 seconds and it makes 8-10psi. When turned down to 4500 it will make about 6 psi with about 4 seconds time. Dave went 10.66@139.83 last night at 3950lbs. He had a 1.655 60ft on 275/40r17 drag radials using the two step for about 2 seconds to make 3-4 psi at the lower rpm setting. I will post video tomorrow on here of the pass and you can get a idea of how it works.

BTW his has a really nice tune in it too so it helps to build the boost rather quickly.

TJ how did you guys get it to only run a 10.66? With a 1.65 60 and 139 ....seems like it should have gone 10.00....? Traction in the middle? I d love to see a video.
I cant wait to try it, seems like an easier way to get the car to 60, esspecially considering poor traction.

What is the advantage of having it with a transbrake?

Do you have any pictures of how it is setup? If I didn't want to power shift, would I run into problems by lifting and pressing in the clutch?

Thanks.

Advantage would be only one button to hold and constant rpm on launch!

just got mine cant wait to use it i talked to LPE they say they have a speed switch so atfer 5 mph it shuts off if you wire it to the clutch but its 114 bucks i hope this helps

Anyone else?

Um, if it's limited to 4,500 rpms on the launch, then when you shift it's gonna be 4.5k again. Not where you want the rpm's when you're powershifting. Going from 6200 rpm's to 4500 is gonna kill your shifting.

So what are you doing to get around this?

Its only limited to the "4500" on the clutch switch....which is a very short period of time. Basically, if you shift at 6200, wot, the rpm probably wont even have time to fall to 4500, but it will not be going up, if you miss the gear. If you miss the gear, it would probably hit the 4500 and stay there. On a turbo car, the tiing could be temporarely pulled to keep th eturbine speed up, between shifts with more exhuast heat. Once the clutch is engaged, it would be instant boost, instead of a slight fall on some cars that build back to the the gated pressure. All this happenng in times of less then a second though.

btw, got mine last night, putting it in now.....Ill try it out tonight.
