Advantage of 2 Step on Stocker???

And here I thought two steps were for drivers that weren't coordinated enough to look at a tach and the tree at the same time.....we used to call 'em rookies.

As you stall up the converter, the boost comes in, so then the stall speed increases, then more boost and so on ,until the brakes no longer hold . The 2 step caps off that process at a predetermined point, in my case ,about 3800 rpm.

Very good to know....interesting and makes sense seems like one of those things youd never know unless youve been there, building a twin turbo 72, I was going with a 6 speed but if I go auto Ill know, thanks Mark.

x2. Noticed some main cap walk this year but I also hit the 2 step on the big end a few time by accident. Not a good thing when the engine goes from 6700 to 3000 then stalls. I now have a switch that engages the 2 step in low gear only.

when you get below 2000 rpm it will pop and back fire ,,there isnt enough engine revoluton for the engine to come off clean once the trigger is pulled ,,,as far as damage ,,might be a little harder on the bearings

Depends on type used. Some cut the ignition only and the fuel keeps getting dumped in the dead cyl's, others cut ignition and fuel such as some used on FI, however not all FI 2 steps cut both either.

Don't forget tranz brakes.

It all depends upon the car and carb. I have a 14 second bracket car equipped with an edelbrock that leaves fine at 1050-1100 rpm off the two step. It's been quite successful.

Michael, if you would PM me I want to ask you about your combination. I have a 14 sec street car that I am bracket racing this yr.

Thanks

Robert,

Pm has been sent.

Pat cook or anyone else who uses a brake pressure switch to release their 2 step. Where'd you get it, do you also need a gauge , is the pressure adjustable, and where/ how is it plumbed into brake system?
