Street Torque Converter Preference

Larry,

I'm with you on the the variable pitch converter being too loose when leaving from a casual stop when in high stall, you might want to consider manual control in a situation like that, even to look at the original intent for the variable pitch.

From a stop sign, I'm in high stall until I push the pedal, then low stall is actuated as soon as I accelerate. When I leave the stop the transition to low stall is really smooth, so much that even with the big cam, the car moves at part throttle with no problem and doesn't lug down at all.

In other words, off idle acceleration doesn't need to stay loose with the VP converter. Use the moment of transition from high to low stall to your advantage when driving. I don't know if you have that kind of flexibility with your setup, I wouldn't trade the switch at my hand for anything (unless I was a competitive drag racer).

Hey Larry, maybe you can place an addendum to this thread title since it has been hijacked into an "11/12 Second Combos" and "Critique Larry's Combo" thread:

Larry,

Thanks for more info on the timer. I was thinking about your previous comment "the high stall is too high for regular stop and go. The low stall is a bit too low. I'd really like something in between if I can get it." which is why I emphasized how much I like the function of the OEM switch that goes to low stall as soon as the pedal is depressed coupled with a manual switch to help out when a little more stall comes in handy in casual driving.

You could always keep a manual switch handy in parallel to the timer, that wouldn't be tough to wire. I'd even suggest bypassing the timer and take the car for some stop and go cruising just using the manual switch at your whim to see what you think. Of course no toggle switch, I'm talking about a momentary switch "normally open" or "NO" for this.

I'm guessing you may have tried the manual switch before by itself, so maybe this is moot, but I thought I'd throw the suggestion your way. Having high stall at my fingertip is very useful for me when driving around, cruising, parking, what have you.

As far as track results, my experience says low stall after about two seconds is best. High stall for the whole run got me the same mph, but longer elapsed times.
