two step for starting line and burnout
 

This is my first year in stock eliminator and I'm trying to be competitive so I'm putting an adjustable brake pressure switch on. The way I read the rules a 3 step is not allowed so I'll have to use a 2 step. I have both available. The first stage of the 2 step I can use for the starting line rpm. Is there a way to use the second stage for the burnout rpm? Maybe connect the burnout chip with wires to the 2 step and use a switch to disconnect it before I leave. Thanks

Re: two step for starting line and burnout
 

You should be able to control you rpms in the burnout with your foot. The 2 step is bad news on the burnouts. And you don't want to be on it any longer than needed at the starting line.

You can buy a 3-step from MSD. I always ran one and as far as I know, never had a problem. At least not the bottom end. For all I know it didn't help with the OEM stamped steel rocker arms. I do a 3rd gear burnout (4-speed) at around 6400 RPM after dumping the clutch at a little higher RPM. Very little "miss" noticed. The reason I ran the 3-step was for consistent tire temp. Same burnout, same RPM every time. I had a separate switch for burnout RPM.

This.
As far as tire temp and 2 / 3 steps........I thought thats what a tach is for.

Re: two step for starting line and burnout
 

My burnout rpm is barely higher than converter flash. I start the burnout in 2nd gear, bump the limiter, put in high, bump the limiter, then hold it just under that for a couple seconds and drive out of the water. My piston to valve clearance is pretty tight so I don't want rev it too high in the water and hurt it. Is a 3 step legal in stock eliminator? I have a 2 step and a 3 step already.

David Reher wrote an article in Dragster on two steps and burnouts, he talks about taking identical engines apart from those who use them and those don't, and finding bearing wear due to constant harmonics at one speed caused by a two step in a burnout under a load. I found it very informative, it would be nice to find the article again.

I find the comment by David Reher interesting, and it makes sense. I believe that however you do the burn out.... do it the same every time. That way, if you don't hook, you will have better information to make an adjustment....."did I do too much or too little of a burn out."
I have tried everything at one time or another. I do not use a two step for a burn out. I find that it only confuses me in my starting line process.......Separate button for line lock and trans brake.....set the front line lock, then shift.....too complicated for an old guy like me. I have my wife align our car just on the forward edge of the water, therefore, I know that water has covered the entire tire. I foot brake it in second and soon as it starts to spin, I shift to third....I count 2 seconds (same as I count the tree) then I lift.....I use Mickey thompsons and they don't seem to need as much burnout as others....plus, they last longer.
It kills me to see someone stop in the middle of the water to start their burnout.....then sit there spinning and slinging water into their fender wells....................only to have it drip on the tires later. That doesn't make any sense to me, but did I say I am getting old (I can't remember lol), and getting another year older tomorrow......oh crap

Re: two step for starting line and burnout
 

Thanks for all the input. When I do my burnout as soon as I hit the limiter in 2nd I shift to high then as soon as I hit the limiter in high I back off just a little to keep it off the limiter count to 2 and let off the line lock button. Limiter is set for 5400 and converter flash is about 5100 so I try to keep it above 5100. I also have someone spot me at the edge of the water. People that do a burnout in the puddle really mess it up for the next person in line. I've been bit by that a few times.

Didn't they outlaw the 3 step in stock? If a 3 step is legal for stock, I will reinstall mine.

Re: two step for starting line and burnout
 

This^^^
Sounds like your burnout is way too long. Been doing 4-5 second burnouts, shorter on hot days, for over 22 years in a 3 speed footbrake car without a 2 or 3 step. Don't make it harder than it needs to be as has everyone of my competitors in NHRA Division 1 competing in the Summit ET Series.

Re: two step for starting line and burnout
 

Once again your ignorance is showing. You know nothing about doing a burnout in a Stock legal car, so please stay out of the discussion. What you do in your 9 sec car offers nothing in comparison....especially to someone running I/SA.

Re: two step for starting line and burnout
 

I think they did, check with tech. I see you liked it also and with a snappy little engine like yours, I can see it getting out of hand on the burnout.

I have my 3rd step out because I went to an ICE Ignition and they didn't have that option; only a two step.
I'll be at the shop tomorrow but I understand they finally put the heads on the short-block yesterday. I gotta think it will be ready for the dyno by Friday this week.

it's YOU that is ignorant with your CLUELESS comment.

Oh no......it's "Mr. Know-It-All" from "The Rocky and Bullwinkle Show".

Last month at the IHRA National event in Michigan,my Mom had a problem with the brakes not holding the car in the water box,so she drove around it and did a dry hop.Staged and left the line with the best 60 ft of the weekend.Your results may vary.

Re: two step for starting line and burnout
 

My burnout goes a lot faster than it sounds. About 3 -4 seconds. Barely any smoke. As long as the track is not messed up it hooks. If I rev it too high in the water the pistons meet the valves and then it's a bad day. That's why I like the 2 step for burnout. I think I'll try the switch between the burnout chip and the high side of the the two step. Hope that's legal.

Re: two step for starting line and burnout
 

Jeff....I was trying to decide myself on an ignition system for my new stocker project and was looking into the ICE ignition also, but found out they are NOT an approved NHRA legal ignition system.....

Re: two step for starting line and burnout
 

WOW! Glad I read your post I was looking into the ICE system myself and I did check the approved list and its not listed. Guess I'm going to go with the 7720/7730 set up.

Re: two step for starting line and burnout
 

I don't see the factory single point ignition listed either. But it's legal. It's just an ignition box and does nothing but spark & limit RPM. Nothing else. I know the ICE Ignition is being used by at least one NHRA multi-time national record holder.
At least the Chinese aren't making knockoff ICE Ignitions and they aren't in BK either....

I guess someone needs to submit them and get them approved for use

I'll get right on that with my Accel dual point.
