Currently six speed but only likely till spring then 4l80 with a 3400 yank py stall or something similar.
I have adjustable kyb shocks, car is dropped about an inch but have lower control arm relocation brackets. Have hotchkis boxed lower control arms and will have bmr adjustable torque arm. Be running likely 16 inch et street radials.

So not sure will run the m6 at all. I got the two step as figured it should give more consistent launches and the antilag should help also regardless of auto or m6.

Once again as i said. Its easier to 60 ft on motor, then it is with a big turbo on stock cubes. with a stock motor...

I agree. Those were some of the hardest tires to mount. I had to up the pressure to over 100 psi for the bead to seat. I cut lower short times without the rims spinning in the tires and so have many other people. The tire psi is higher than a slick.

It should be easier on the motor as you are sitting on the line under less power with intermitant firing of the cylinders compared to motor making more power on all cylinders.Of course loading up on the motor for any length of time with a stock motor does cause some kind of risk either way.You also need to decide if your drivetrain will take the shock with out breaking.If you are looking to buy this setup just to save your motor I wouldn't bother.
Good luck.

2 step would be great to get consistent launches. Same rpm every time. With a nitrous setup you could do a rpm module that would spray @ what ever rpm in what ever gear.

Sponers like Dynotune nitrous sell them for relatively cheap.

With nitrous in 1st gear right after the launch or even on the launch i dont see any problem running 1.6 or 1.5 60 fts as long as the drivetrain can handle it, and you are on a good tire. I would also make sure you have some good suspension doing its job, you can loose alot there.


Good luck, Chris

my drivetrain is more than up to the job to take what ever i can put to it
the traps 128 in the 1/4 but the 60ft sucks at 1.9 with slicks. my tune has alittle to do with it to.
i can use my eboost as a window switch for the n2o

twin rear mount c5, 6 speed car with 3.15 gears, 347, low compression, zo6 cam. I ve only used it once at the track (1.68 on second pass with slipping clutch), but it instantly made cutting a light possible, and its not the rpm vrs boost, but rpm/time vrs boost.

I see 15 psi at 5600 with 14 degrees retard, in about 3/4 pops.....and I mean loud pops, throwing flames out. If I set it lower it still builds boost, just takes longer. Doing 70 mph roll ons is a whole new experience too.....depress clutch, pop, pop, pop.....boom.......whoooooosh....

I wouldnt even build a 6 speed turbo car without one, way tomuch fun, I mean its worth it just for the flames.......and insta boost too....

WOW leaving at 15psi...thats sounds awesome..1320 has a lot of turbo toys .DOUBLE WOW!

So looks like my new ling two step can do a good job. Wonder how useful the antilag thing will be on an auto car..anyone tried one on an auto car yet..?
I was wondering how much boost would get on a 4l80e with py 3400 stall and no trans brake or is a trans brake also key to builiding boost. Not being a track car would prefer to just maybe use my two step, antilag and not bother with a t brake.
but would still like to turn a few good times at the track till car gets the boot.Which might be first run! LOL

well it would still help make launches consistent and the antilag should still help not sure how much boost would build with a auto and 3400 stall .this whole thing is a bit confusing. Do I use my line lock and a t brake if had one?
I am not much of a drag racer obviously. But will track the car a few times to get that timeslip for the wall and hopefully a 9 second one!

us m6 guys need it to make boost on the line. if you have a auto with a brake you have all you need IMO a 2-step is just more **** to mess with. i just like to keep thing easy
but i can see it making things more consistent as well

Sorry, I spent yesterday with my boy, at appoinments for pre k preschool stuff. Then we worked till about 2 am on my allwheel drive van dvd stuff then we had to switch over a 99 turbo camaro to SD. A long day.

The 2 step (with retard) made it much much much easier to drive and luanch the car. We only had it out twice before the 2 step, and the owner couldnt get it to leave at all, horrible 60's......I have a lot more experience and had to drive the car very hard and was inconsistent. But Im a long time bracket racer too, from super comp, so my standards might be scewed alittle.

The two step made it more fun, easier on the car and possible to et much much much better. How much...probably on average .75 sec...but from best pass to pass...less, but you get 9 out of 10 decent passes with it, were as without it, you get 4-5 decent passes out of 10. On friday, I expect the vette to go high 10's if all goes well, and if it has issues, track prep or car issues it will go 11.0's to 11.1's. Up until now we have been regulated to 11.50 and slower due to saftey regs and the days it would be at the track on.
The day the clutch broke, it had a 1.68 sixty, and had previously trapped high 128, weeks before. I m hoping for a 1.6 sixty and 130 mph trap, that should be well into the 10's. Before the 2 step, the 60's sucked and were all over the place. That was in part to tune as well, as it was a partly tuned sd tune at the time.

The 2 step with retard did change the car, for the better,more fun, more consistent, and easier to 60, and cut a light. On a three amber tree the vette sees boost from the 1st bulb to the last which was impossible before the 2 step.

good info sounds just like my camaro at the track it was cutting 2.0 to 1.9. the best i got out of it was 1.88 but i did have a clean pass with that. i ran the car 8 passes with my best time of 11.68 at 128 with a 1.9 60ft and i was only running the rpms to 5800 because of the stock bottom end and the 12psi of boost. the 1/8 mile was 7.5 at 99. but it has some bugs to work out still. im going to turn the boost down to 10psi re-tune and ill have the 2-step on. im hoping to get it in the 10s what do you guys think? it should be doable right?
