My Novi builds 4 to 5 pounds of boost on the 2-step...and that's at 2800 RPM. Shocked the heck out of me...I only thought turbo cars would build boost off of a 2-step - shows you what i know.

I bought mine for consistant 4000 RPM lauches - but the boost I was generating has caused me to drop the RPM much lower (see above), I'm stilling trying to get it dialed. I too am curious about the possible negatives of using the 2-step.

Now I have to decide between in consistant high RPM drops or low RPM - boost assisted line lauches.

Good question - I'll be watching this thread...

The best PnP 2-step (not really a 2 step in the real sense of the word) would be the LPE-LNC-001. I run it, love it and wish my clutch would hold but that's another story. You will kill stock cats eventuaqlly running a 2-step.

How about putting a line lock in series with the clutch where you would hold the clutch in, activate both the 2-step and line lock with one button. When released, it would engage the clutch and drop the 2-step all in one move.

Plausible??? Worth doing??

Depending on your setup though, in theory it would work. Push the clutch in, engage the line lock, and when you are ready to leave release. It might be akward pushing the clutch for the 2nd shift though, just because it comes to you so secondhand to launch off the pedal.

Now you got me wondering!

I read that launching with a line lock is illegal due to the possible chance of one or both sides sticking and sending the car sideways.

That's got me curious. What or who's law? NHRA, IHRA or sanctioned tracks or just certain classes? Do you know if it's illegal to have in certain classes or entirely on a NHRA or IHRA sanctioned track? It would seem kinda like a transbrake to me, but on a standard tranny. I know that the transbrake locks 1st and reverse together though, but I've seen some nasty stuff happen when that button is let go. This has me thinking that based on the risk of sending a car sideways, there's tons of things that should be illegal.

Line lock on the clutch not on the brakes. You activate the 2-step and hold clutch in with one button. When you release the button, the car leaves violently. I believe this is what my friend ( forum member Darkside) has on his youtube famous 1700hp TTviper. Look up the launch. It's pretty cool. Car is Charcoal with red stripes.

i have my 2-step tied into my clutch switch and relayed into my nitrous. i stage, depress the clutch, hit the mometary switch, and floor the car. it will stay at the programed rpm and when the nitrous is armed it will spray as soon as i let off the clutch. it makes for consistant launchs. the only advantage i can see tieing in your line lock would be if the lanes rolled or to preload the car. here is a launch from last sat.

Push in the clutch, push the button and let out on the clutch while holding the button. Then stomp the gas. Release the button and it will release the clutch automatically. As stated above, it's violent. Maybe too violent.
