Default Harlan Two Step...

Anyone see better launches and 60 ft times with the Two Step? I'm dying to get into the 11's, but my launches suck because I have a hard time finding and holding my launching rpm while watching the tree.

Any comments are appreciated. My last run was 12.6 @116 with a 2.2 60'....

I got consistent high 1.4's using it.

I would definitely recommend good sticky tires, a good clutch, and a good driveshaft (along with your 12-bolt). If you want to launch at 5500+ RPMs (mine is usually set to 6200-6400), you want to stick and you don't want to break.

Thanks for the reply. For now, I got Nittos, 12 Bolt and 4.10s. After I roast the Nittos I'll go with slicks, but for now I'm hoping to crack the 11's with DRs and the stock driveshaft.

The first time you use a 2 step to launch the car, you'll never go back! It literally takes all the work and inconsistency out of launching. Get one.....you'll love it even if you're only launching at 3k now.

It's OK to post a link. Nobody else makes a 2-step for the LS1.

http://www.harlan-engineering.com/store/store.html

Matt Harlan (y2khawk) makes them. He also has a day job (which he sometimes has to travel for), so it sometimes can take a while to get them. 6 weeks is not an uncommon lead time, so don't expect it 'fast'.

His design is plug and play for the LS1... not sure it would work with the LT1, since it's meant for individual coil packs.

i think i kind of understand it. Does it rev the engine for you or do you rev and it stays where you set it for? how do you install it?

Im pretty sure its an electronic limiting device which cuts ignition at a predetermined RPM, specified by you. Very useful for turbocharged cars, like mine (well, soon anyways )

Yup. You can floor the gas pedal, but the Two Step will hold your predetermined rpm setting at whatever you choose. Dump the clutch and you've already got the pedal down, making for a

You can hear it in my video in this thread. I don't remember where I had it set, but it was somewhere 6200-6400. (As the lights are coming down, you can hear me floor it and hit the 2-step limiter).
