I promise you your car will not be any quicker without one or minimal at best. Autos are faster not because of shifting of gears. It is because of building of boost before launching.
Two ways to build boost, load or retarded timing (which)exploding fuel in the exhaust pre turbo to rev the turbos...aka a 2 step.
You could rev to 9 grand and those turbos will spool no quicker than at 2500rpm.
Had you went blower different story, na its a different story, but you chose the turbos for a reason. They make more power per psi and just haul ass. Ive never seen somebody switch from turbos to any other power adder. Only if they didnt know what to do or money was involved via sponsors. Even then its a rare occasion at all.

You are very persuasive. I thought all 2 steps do is hold the revs at launch, but since the engine is revving freely, I didnt see how any boost could be built. But after reading it does seem possible. I suppose it would be a nice thing to have if I could choose to use it or not. Is that possible? Not sure I want something that messes with timing, gas, or making the engine miss on the street, besides the point that doing any of those things badly can be hard on the engine and drivetrain. And I wonder if rev matching a downshift might be affected by a two step.

two step usually is only activated at launch than it does no affect to anything at any other time

Two step is basically a 2 wire setup. It can be operated by a button on your shifter or clutch pedal or a button on the steering wheel. Which ever your more comfortable having it. It is only activated when you want it to be. Id personally put it on the shifter (cuz I use pistol grip handles only) to release the same time id dump the clutch. It only limits rpm nothing else. The way it works is extremely useful for turbos and manual trans or lencos when load is not possible at staging. You can even run a three step. That is a multiple rpm limiting device that could further improve things with the launch rpm and high limiting shift rpm so you could no lift shit to boot.

Any more questions please ask away..ive been there done this a time or two.

Fyi...two step is not hard on anything but your senses till you get used to it.

I think the MSD two step works on a clutch pedal switch. I suppose that could be changed. There is enough going on with my car now, I will look into this later.

You can activate a two step anyway you choose. Its like 8o bucks or so or you can make the stock ecu do this as well I believe.

I will keep this in mind. Ted says it's not so simple or cheap to do it right. And I would need slicks to really take full advantage.

I am making a number of changes to my car. I want to see how this all shakes out first.

Any updates on your mods?

[Fraxum]

Car is still in the shop. Hopefully I can pick it up Tuesday. But there is a 500 mile clutch break in. So also hope fully I will have that done by Friday and Saturday with back to back running.

[JackalopeZL1]

Looking forward to the update

More delays. But I think for the good. 2 Step not going in, but a line lock is.

Adding new injectors: Injector Dynamics (1025 cc / 96 LB HR AT 58 PSI) Along with the ADM ZL1 pump controller. The car is done except for the injectors and tune.

With this setup if I add Meth, the stock LS3 bottom end is the limiting factor as to how much power I can add. (I think.) Another 1LE recorded 800+ RWHP with my setup and Meth.

Amazing. Just the AGP kit, injectors, pump controller, meth kit, and a tune. Tire shredder. Although, to be usable a new clutch and a little suspension work is required. And tires.

But since long term durability is my goal, I hope to be happy with my new high boost setting.

Ted is great to work with. He is willing to explain anything you ask.

[JackalopeZL1]

I agree, I too have bought from Ted just because of the customer service.. Goes a long way in my book.

Whats the line lock for besides a burn out? You cant load the car with a manual trans and a line lock. Just sayin.

True, that's almost all it's good for. But it's also good for the safety of the track staff. I am not able to get the hang of using the brakes for my burnout so I start rolling too fast. With the line lock I can better control my burn out and do a slow roll out of the H2O.

I am not ruling out a 2 step if I get more serious about drag racing. But with a better clutch I should be able to get a more consistent 60'. Right now it's 1.7-2.0. Ted didn't think for what I was using the car for it made sense. And I would get the best benefit with slicks. Once I put slicks on the car I better put in stronger axles. And then the diff is at risk. As you say there would be benefit, but really it came down to $$ and time in the shop. The car has already been in the shop 2 1/2 weeks.

But say at some point I do get serious, I would go auto, slicks, a 9 inch rear, add meth, pump up the boost to 800 rwhp, and start removing weight. Then low 10s should be pretty easy. And then my 1LE would be awful at autocrossing.

But I have not tried that yet. A future obsession. I will have to start a new thread:

Twin Turbo 1LE versus 2008 Miata.

Getting the car back Thursday, Ted wants to make sure everything is right. Can't wait.
