Re: Your experience foot brake vs. 2 step regarding ET
 

We experienced a marginal performance improvement of .01 to 02 with a 2-step on a low hp Fox Body stocker. Would have to make a few more runs to have a better idea with reaction time, but certainly made staging easier/consistent.

To Bobby's point, we did not adjust fuel enrichment to accommodate the change so not sure if it's a true apples-to-apples comparison.

my car hates it (as do i) kills me about .05 at least - more in bad air ....

Dean could you better explain to me about adjusting the secondary for a FB two step? I have a street car that I Foot brake. I leave around 1500 and it flashes to about 3800. I tried a two step one time and while it reacted quicker to stumbled about 10' foot out and then cleared up. You can IM me with any details if you would like. Thanks

Maybe someone will see this and reply but has anyone experimented with low rpm 2 step ......will the motor respond ok on the 2 step at 2000 ????

Re: Your experience foot brake vs. 2 step regarding ET
 

Don't know about 2000 but my R/SA Jeep 4.0 leaves fine at 2550 - down from 3000 because the brakes won't keep it from pushing thru the lights!
4.0 is FI so can't say about a carb reacting.

Re: Your experience foot brake vs. 2 step regarding ET
 

I'm finding out little by little with experimentation, and it gets back a little to what some of you hinted around to, the quadrajet does not like "rich" fuel mixture when leaving on the mat with the 2 step activated by the brake. It will sit on the starting line and hold the RPMS but when you let go the "rich" will usually make it leave terribly, even though it will run great with the same carb setup when running with the footbrake only.
MAKING THE 2 STEP WORK WITH THE QJET IS A CHALLENGE in order to get it to perform at its best especially on a stocker that doesn't have a transbrake and has to leave at much lower RPMS......by what I am seeing testing the 2 step requires leaner setup to run at least reasonably well.
Does anyone else have similar findings ????

Plug the accelerator well tubes

Re: Your experience foot brake vs. 2 step regarding ET
 

I used to leave at 2200 with my 455 Lemans. I did what Danny said. blocked off the accelerator tubes and it left great. Always to the floor.

Re: Your experience foot brake vs. 2 step regarding ET
 

I`ve been using a 2 Step anywhere between 2000 and 3100 rpm and the 60` times seem to be about the same. All of this with a V6 "Stocker". I`ve also gone back and forth with foot braking as well and prefer the 2 Step for consistency. Low horse, small carbed cars seem to be more consistent leaving at WOT. I also 2 Step my Super Pro car (big block Chevy with a 950 Holley, dual line lock set up) with the 2 Step around 1900 rpm and it leaves just fine.That's my experiences at least.
