why 3000 rpm stall ?

[mungce]

What are so many of you all going with Stallion 3000 rpm stall converters ? My understanding of such a high speed stall is when the cam is so hot thati it " loops " and tries to stall out. Set me straight, please !

All a stall does is dictate roughly what rpm your tranny engages your gear at. These motors make all their power past 3000rpm. By increasing the stall speed, it gets your motor into it's power band quicker, thereby increasing how fast you can accelerate from a standing start and helps keep the motor in it's operational power band.

3000 is a fairly high stall for a heavy car like this, however if it's a well built converter it can actually be very streetable. I run a 3200 Street Edge and it's a monster on the track, yet it's quite streetable.

A high stall TC will actually multiply torque at the flash point, or so say the folks at TCI. All I know is that if I'm not careful and punch it in a slight turn I will immediately do a 180. The main thing is that they help get your 4400 lbs out of the hole in a big way. I cut a 1.699 60' the other day in mine.

Oh and one other thing, stall speed is really the RPM at which a converter flashes, ie. goes to 100% efficiency. Below that speed it is slipping, which creates heat. If you do run a high stall TC you should have a tranny cooler because excessive heat is what ruins more transmissions than anything else.

I was in the lane next to him & his car is quick.

However when I get my Nittos on you better look out Stumpy.

Will the converter still "lock up" for highway cruising at say 2200 rpm? Or does it slip under those conditions?

It should, if it doesn't then it's the wrong converter! That's the beauty of the electronic trannies, we get TCC lockup. In fact my RPMs actually dropped ever so slightly at highway cruise because the Edge TC is more efficient than stock.

Hehe, it will be interesting to see the look on your face the first time you pull a sub 2.00 60' time jet. BTW, I'm going to have you throwing those 18" rims out for some 16"s and some real tires, ET Drags baby. Then look for 1.6 60' times! Yeeeooooow

BTW, I got finaly my 12 second run in the vette today! I was grinning from ear to ear.
