Thanx Frank. I took a look at Pat's site. Looks almost like his converters are sort of an off the shelf style...???

I've read somewhere that there's a company that takes the weight of your car, engine hp, torque, etc. and will build a converter to your specs.

Could you also spin your tires if you were doing 50 mph on a dry paved road and then punched it?

You can buy an off the shelf converter or get him to make one for you.. Depending on road surface. at 50 mph if I punched it to WOT, the tires would spin maybe 1/2 the time. It was an intense ride, thats for sure

Did anyone point out that the smaller converter will not change the HP or torque output of the engine? It won't. As stated it just gives you more revs on launch, and it will give you a small decrease in rotating inertia which will help acceleration a bit.

It also will make more transmission heat and worse MPG in street driving, if you care. Living out west where distances are long, and summers are hot, I would care, but if this is strictly a fun car, or a dedicated street/strip car with emphasis on strip, more of a street-legal drag car - OK fine.

Actually, I'm being told that on my car it will not have much stall until I start building boost, because a V6 with a turbo doesn't make much torque...only maybe 200 ft lbs of it...until the turbo spools up and thus adds torque...and it's the torque that dictates where the torque converter will stall. In fact this guy tells me he's installed a 3500 stall converter in a turbo 6 car and it drives like a stocker until the turbo is spooled.

I have had experience with a 3000 stall behind a big block V8 and without overdrive.

My 2800-3000 stall converter drove just like a stocker in every way.. There were no downsides to it..

It may not make any more hp/tq....but correct me if I'm wrong...it will put me more into the "kick in the nuts" range and thus allow me to accelerate faster due to a more onset of power...?

Even if I weren't drag racing, wouldn't a loser converter required for such vehicle be sort of like (but not really) gaining a few extra ponies?

Frank, I tried to rep you, but it said i have to spread the reps around first. The convertor like you had works very well. I absolutely agree at least 4 tenths is left on the table of DEENUTTZ ride on launch alone, not to mention the lower e.t on down track. 2.0 60' is not anywhere near capibility of these cars. I would also reset your injection to come in later as it may be hitting at the wrong time to launch. instant rich/ loading with the additional fuel can kill power taking off.

Yes no more hp, but better acceleration.. Its sort of like changing the rear gear ratio. No more hp but better acceleration.

Here's another one for you...

I know a higher stall converter (suited to my combo of course) will help drop my 1/4 mile times, traction provided.

However what about the trap speed? If I went with a bigger converter (again suited for my turbo/cam) will my trap speed go up? Or stay the same?
