What is a 2 step used for? I saw some vids on youtube and all the cars that had it were crazy loud and fast. They sounded angry. Lol. is it used for drag applications or something? They all seemed to resemble some sort of drag machine.

 

Launch control
2-step is 2-step. It sets a rev limiter, you keep it floored at your chosen rpm, and drop the clutch.

Launch control should be thought of as electronic launch control. The sensors detect wheel slip, and it interrupts the power output trying to give you the best of both traction and power. The more expensive/advanced the system is, the better it is. It's basically like traction control but for a launch. In the newer cars you can screw with some settings to tell the car you are about to launch, and it will adjust different settings to give you the best launch.

But where our cars are concerned, 2-step is the only artificial launch control we have unless it's a more modern vehicle.

 

i see. I was starting to think its some sort of rev limiter.

 

If the rev limiter on a 2 step is a spark cutting rev limiter, when spark is cut but fuel isn't then fuel is dumped into the exhaust and then ignited which results in the pops and flames that you see and hear

 

RX7 launch control = rev engine, dump clutch

 

^ haha. nice.

 

from what I understand, a 2-step is primarily used to aid with turbo spooling in drag racing applications (supposed to be able to build boost prior to launch). not to be confused with those anti-lag systems that will kill turbo's in short fashion if used daily (mostly a system found on turbo rally cars).

 

Thats cool. IM not into drag racing though. Im into the drift. So I guess this wouldnt beneft me.

 

Um...no.
Now anti-lag on a drift car might be interesting....for one event, lol

 

anti lag systems kill the exhaust systems in short time too don't they? thought I heard that somewhere. anyway, not really needed on a drift car since it's not about time. just learn to drive the turbo properly or go 3/4 rotor na or v8.

 

anti lag system is not by anymeans worth the destruction it does to your engine, turbo or manifold.
on the track your always at redline, you lag should be nil.
if you have so much lag while street driving then you've got the wrong build
the only time this works is for rally cars when the need to wait for the car to slide out for a bit before getting into throttle. and short of WRC the cost of an antilag system isn't worth the couple seconds it might take off.

That's one of them 7/11 songs. Same 7 words, repeated 11 times!

 

That video is more than stupid. Ya fc fan ive looked into the 3 rotor NA and Its way out of my budget. Im gonna stick to what I have. Its definatly enough for now.

 

I say anywhere between 300-400 rwhp is more then enough for grassroots drifting and some competitions. you can get that easily on a 2 rotor, I was just saying that if you hated turbo lag like the plague and the least lag still bugged you then you might as well go some sort of na application rather then anti lag systems.

I am on a super tight drift budget too and am going to do a t2 swap to my na. s4 keg with s5 manifold and turbo to start. I'm shooting for 300-350 rwhp in the end so may upgrade the turbo or do hybrid but I'm doing suspension first and driving na for a while.

 

Dude you read my mind. That's exactly the power I want to get to. I'm gonna go with a BNR stage 3. I'm gonna stick with the stock tubo for the time being till I'm ready for more power. Someone was telling ne the lag is the same as stock turbo and the turbo is good enough for that power.

 

ya, you just gotta balance your turbo efficieny with the power you want to make. different turbo's have different lag times a little bit but a hybrid bnr should be fine once you get used to it. lag can also be effected by other engine functions/parts but the biggest factor is gonna be porting. bigger ports are gonna lessen your lag time but bridge porting is generally not popular in drifting. stick to stock ports or some type of street port. I'm doing a medium street port myself because my car will be daily driven as well. there are threads about porting so look them up for more info if you need to. any way you set the car up though, you can get used to it. after a while you will predict the lag second nature, just like using a clutch pedal the first time. after a while you just do it without thinking. good luck.
