Looking for a 8" converter that will stall around 6000 behind a 13-1 355

Ah I just had to order a new one myself. Except I opted for a 10" from PTC.

My dad has a BTE 9" that stalled about 5100 behind a 550 HP 406 with minimal runs on it. Been sitting on the shelf for some time. I can get more info if anyone wants.

Mark I'm playing with that POS 355 engine in that lard ass 3500lb Studebaker. I got a 9 inch in it now that stalls at 5500 behind a pump gas 434 but it only goes to 3300 behind that POS engine. Changing converters got me .3 slower than last year with that "super loose" 10 incher that was in the car then.

Ron Owens sent that 10 incher to BTE last week to see if they can do anything with it. Should hear something from'em by weeks end.

Don't know if you've been keeping up with that never ending saga but I've had two different verters and three different intakes with two different carbs in that thing and been testing my ass off and just about everything I've done with it has slowed it down even more. Hell, last week it only ran an 8.41??

We prolly won't take that one back out until I get a verter to go in it! ;-)

This who has done our converter and many out law cars around the world.

http://bradcoengineering.com/ \:D/ \:D/ \:D/ \:D/ \:D/ It is a one man operation. So when you talk to him you are not just talking to a sales rep. Check out the customers. :- The guy from Sweden and Austraila haven't been added either.

Seriously though, I believe ANY converter purchased from ANYONE is a crap shoot! Probably only 1 in a 1,000 (or another random number) actually is dead on out of the box for a particular application. Hell, look at Scott Smith. I'll bet he has had a dozen different combos in his car before he finally got where he wanted to be (if he's there yet that is). And on top of that, if you change ANYTHING on the engine that changes the power band/output then that changes where the converter needs to be!

So having said that, I think working with converters is about like doing dyno work. Ya can't go from one to the other as each will be different, ie, if you dyno an engine on Joe's dyno, then make changes and then carry the engine to Jim to dyno on his dyno you don't know where you are because there is likely a difference in the two dynos. IMHO same applies to converters, and a host of other things.

Exellent point Ken. If you change one thing it changes everything. I like Brad because when I take it to him he cuts it open with you there and makes his inital checks. But we live close enough to drive there. I have seen him at the track help a team pull a converter and adjust it on the spot between rounds. Bolt together of course.

Yeah Steve, that says a lot about his customer service for sure.

And speaking of bolt together verters, I've often wondered about those and how much of that stuff could be done by the owner? I'm sure that the "black magic" involved in converter work is just about like the "black magic" that carburetors used to be. I'm tempted to cut one open just to see what's in there. ;-) It can't be rocket science cuz there's too many people doing them!

The bolt togethers are adjustable. How I don't know. The non bolt togethers like mine he changes a rotor or stater with a different pitch. I imagine thats what they do on the bolt together also now that I think about it. On ours he also made sure the fins were welded completly and they were at the most optamal angle for our set up. It is pretty interesting.

Some good info on stators here.
http://www.dragstuff.com/forum/viewtopi ... =16&t=2365

Marty has been good about giving honest answers to questions on converters. Also that two converters can stall the same, yet one will outperform the other. Makes choosing a converter and company a wonderful chore... ](*,)
