Hopefully a simple and short question...but I have never had the opportunity to try... With my stock converter, It didn't used to peel out much unless I applied brake from a stand still. It would slip a bit, but not break loose into a real peel unless I braked at the start. If I had some stall, like 2500-3000, would it rev up more before catching and let the tires break, or does the stall only work with braking also?
i dont think thats the intended purpose of a stall converter, but im intrested to know the answer as well
I haven't tried it with the new engine. I am still "babying" it. I am talking about the old engine. The old engine would spin a little at the track, and worse on the street, especially if I gunned it during a turn, but not as much as I have seen other "muscle cars" do. They seem to do it without trying, and I was wondering if it was because the stall let it rev up to the power band, and not engage right at 1800 where there really is no serious power being produced by the motor. Could also be that I am comparing my engine to 440 and 454 big blocks...
yea, think of a high stall converter like dumping the clutch in a standard transmission...except..u can do it endlessly with an auto if you like...http://www.fordmuscle.com/archives/2000/09/converter/ it's a really good article, it should answer all of your questions...the site is really good as well, I'd bookmark it
In a nutshell, yes. Your converters stall should be 500 to 700 RPM lower than the RPM your engine makes max Torque. As you mod your engine to make more horsepower and torque, the RPM at which it achieves these gains gets higher and higher. I am not sure what a stock 302 converter stalls at. I would guess between 1600 and 1800 rpm. That stock engine makes torque at 2000 rpm. Your engine doesnt. You have a big cam in there with lots of duration and Your engine probably has a peak torque closer to 4000 rpm. So when you punch it, your engine dont have the torque at low rpm to shred the tires. A 3500 rpm stall converter would put a serious smile on your face. I would call a reputable manufacturer and see what stall they recomend. You are definitely gonna need a higher stall than 2500. There are a bunch of articles on the internet. Here's one from Summit Racing: Summit article.
I have the 3500 stall and it is awesome. yes you need something biger than stock. If you have a trip to north houston I will be more than happy to give you a ride in my car.
my Son (the boy) got a ticket downtown for ...laying 200' of Drag, he was driving my '02 S10...4.3 6cyl. ...frank...
Just put a line lock on the front brakes and then you can burn those rear tires off the rims. All you need is some HP and if all else fails, have someone dump some water on them. On DOT type street tires, the more you "peel out" the worse traction you will achieve, especially in racing. For camera's or showtime, let er rip. Yes, higher stall will help in some case's, depending on a zillion other factor's such as gear ratio, weight, and of course HP/Torque, just to name a few.
my converter is from ati and has a stall speed north of 5000. it has no problems peeling out on the street. i would definetly recommend talking with a converter manufacturer to help get the right parts. it will make a huge difference in how the car responds. i started with a 3000 stall converter. the ati converter picked the car up about a tenth and a half in the eight mile.
convertor And remember that a cooler is really an important addition when going to a higher stall convertor. An easy way to make a determination is based on your camshaft, it has a peak power band and this will help you in the convertor selection.
