Shifting on the Stop??

65Shoebox · 07-01-2010, 04:19 PM

Hello all,

I am fairly new to S/ST racing and just installed an electric shifter. I am running a Glide with a 1.76 1st gear. Car runs 1.40 60 ft and bottom tens.

My trans guys tells me I should be shifting while it is on the stop. Is that what most are doing?

We run SC, but virtually everyone I know who runs a stop in any class shifts on it. We're on the stop at 0.00 secs and shift at 1.0 secs.

The thing I don't understand is that in effect you are killing the low end performance becuase you lose all the gearing advantage of first gear.

Is this all beacuase of the increased consistency from not shifting gears and allowing the engine to work against the converter?

I guess this is why you need to run a second or more under the index, right??

The low gear still launches the car.You just need to find someone with similar combo then adjust from there till you find what the car likes to be consistent.

That's the whole point, you want the car to run a consistent RPM on the stop, then accelerate from there. If you let the car stay in first, you'll climb when on the stop, which will be very hard to be consistent (will vary with the weather). So, yes, it's all about consistency.

So... I have been engaging the stop at 1.0 and I am basically on it for around 2 seconds. Would you suggest that I need to shift as soon as possible, or around 1.1 secs?

This doesn't casue the trans or converter to explode in a million bits?
