two step vs. no two step

[probeturbo]

I have a friend that has an evo 8 and he has a two step and i have a speed6 or course with no two step. He was telling me that having a two doesn't help your launch any other then feathering the gas upon take off. He feels as though we are leaving with the same power to the ground with or without the two step. Not meaning his car vs. my car but a car with and without a two step.

My best 60ft is a 1.82 and i think his best W/ a two step is a 1.79.

(scratch) i assume you are reffering to the clutch?

Me am confused....

Is two step like two stage?

 

[freekwonder]

two step, helps build boost off the line.

example of an evo with two step.

Two step allows you to hold the gas at a preset (or factory) RPM for launching purposes. This is the 'one step'

The 'two step' is in 2-6th gears, you can rev to any RPM.
Not sure if I'm making sense.

IE: If we hold our gas pedal down at launch, it will over-rev.
IN an EVO, I think it holds at 5k?

So, if we installed a MSD 2-step in our cars, we can set it for 5krpm, hold the gas down, without having to worry about holding at a certain RPM for launch. It aids in launching and in turbo cars, also to build boost for launches.

PRacing has it right. Basically if you have a two step, if your in nuetral, the car will hold at whatever rpm you set your two step to until you release the clutch then you can rev up to red line.

two step=bye bye ms6 axles, no two step= axles

well ok i must have confused you guys with the question. I know what a 2step, launch control, studder box or what ever you want to call it does.


My question was more pertaining to if you had a car with and without a 2step will the one with one leave harder than the one without because he is leaving with more power due to building boost. Or is it just a launching aid and not a performance gain.

Wow this forum is like a bunch of evo owners new to the car world , no offense guys...I've just been into cars for too long

I am the guy that Charles is talking about.

We have debated this for a long time.

My point: a 2-step only aids in launching. Yes, it builds boost when the car is sitting still but ultimately the car has to roll in order to launch hard. By the time I let off the clutch, the drivetrain has a tremendous load on the car which will lower the rpms regardless, then boost will climb as the wheels roll.

His point: a 2-step gives you more power instantly since you don't have to build boost as the wheels roll like the non-2step car.

My point: both cars have to roll in order to leave. Therefore, boost is ultimately the same once the wheels start to roll. In a non-2step car, you'd just slip the clutch slightly and that alone will build boost. By the time you let all the way off the clutch - your boost is max. Just like the 2-step. A 2-step car may get to peak boost before the non-2step car, but the differences are neglible.

Cheers,

well ill argue that the axles wont break if u have this setup on stock turbo.. but if u put it in your car theyll break.. now if u used the two step and custom axles made from a local shop, on stock or big turbo id bet the launches would be sick. and to see if my theory holds true ill install two step and run it at the track with my car and see if i snap the stock axles while im on the stock turbo...

Why do you guys think the axles on the MS6 are so weak? Just curiuos.

uhh most of us own mazdas, dick?

Well.. I broke one... and i'm on stock turbo.. no boost controllers... no engine management... just stock turbo with a few minor bolt-ons.

I know a COMPLETELY STOCK speed6 that broke an axle NONBOOSTED on the freeway... he was just trolling along in steady traffic at a steady speed and it popped. That doesn't mean he doesn't drive the car hard... but it wasn't during some crazy 7000 rpm launch.


Ummm... and I know several others have broken axles as well... and it always seems to be the rear drivers side.

You are right about Evo owners... as 90% of the idiots to buy those rally/drift cars never take them off the pavement.... and DRAG race only... WTF is point of all that suspension and design... if you slam it to the ground and scrape on every bump in the road?

/endrant

Sorry... just bothers me that ppl buy cars and have no idea what they are used for... Which is why i got the speed6... Sure its got AWD and 4 cyl turbo like the evo.... But it is in no way designed or setup for Rally/AutoX or any other crazy s*** like the evo... (yet it can keep up quite nicely no less)

 

[awsmp5]

my buddy has one of those on his civic... thats all i can say i don't even know the answer to your question.

on a side note: evo = rallycross... DO IT

 

[freekwonder]

I personally see a two step only really needed when you've got a bigger turbo (on any car) that you need to build boost on. Something like our car with the stock or just the ATP turbos I don't see a need for a two step.

 

[chriscecc914]

i broke an axle on the stock turbo also with a cai and catted downpipe.


BTW, no car is really produced for the purpose of drag racing.

well ive raced my car at the track and put up some good numbers and i havent broken my axles (yet).. i was thinking of setting the two step for launch at 4500-4700 in that area.. my buddy had an evo and went to a rally type event and crashed it going around a corner at 120mph.. car is toast..
