Newbie Question on Torque Converters

[palerider]

Need to upgrade my torque converter for 347 build I'm doing. Currently looking at the Boss Hog 2200 to 2800 speed for 67 c4 (see attached). Comp Cam set up recommends a 2500 stall. How do you adjust converter to get to 2500? Again probably dumb question. Also - anyone familiar with ACC Boss Hogs converters?

Torque converter stall on a given converter is based on the torque output of the engine it's behind. Therefore a torque converter that stalls at 2200 on a mild 302, might stall to 3000 on a 347. Or 3500 on a 400ci windsor stroker. You can't adjust the stall(unless you have a bolt together converter). That's done by the converter company. They do it in mutiple ways........ stator design(ie # of blades and shape), stator blade angle, stator blade cup, pump blade angle, pump blade cup, and clearance between pump and stator. A good comverter company is worth their weight in gold. Never heard of Boss Hogs. I will only use Lane at PTC or Lenny at Ultimate Converter Concepts.

Call Broader Performance. They know their stuff and make quality products.

What rear gear do you have? You do not want to put a 2800 stall converter behind a 2.79 gear because the converter slips until you hit its stall speed. 2.79 gears means less than 2800 rpm at 60 mph. Slippage equals heat which is the enemy of transmissions.

I also recommend a cooler and synthetic fluid (at $10/quart).

1 experience, not good results, failed in less than a year behind 428. Wanted to build me a new "upgraded" one for a 125.00 plus shipping instead of just sending me a replacement. No big deal , but removing and reinstalling on jack stands and a creeper gets to be no fun after a while.

If you contact any good converter company they will ask you to fill out a detailed spec sheet about your car such as engine size , cam specs, gear ratio, weight,etc. This is the only way to come close to getting what you need. Anything off the shelf is a wild guess.

Corbins - what did you end going with?
