Multiplication factor on 'verter....

[Texas4ever]

What is the multiplication factor on the stock torque coverter on a '97 Camaro...??
Mine will stall at about 2400 before both tires break loose...

Did a search and could not find this exact answer.

The STR and Stall math had a slight variance from late 1996 to 1998 on both the 3.8 Camaro and Firebird.
The stock stall ranged from 1865rpm to 2060rpm and the STR was 1.79 to 2.03. In the late 1997 model year the math was 1895rpm. The excessive clearance coupled with the holding power of the late model braking system would allow the converter to build enough heat to bring the brake stall higher (flash). This was due to fluid break down and slippage, or cavitation. The warmer the fluid in the converter the more the converter would slip. The converter that was used in this application was considered to be "low stall".
The same 245mm converter used in the S-10 2.2L application in the same years had stall math of 2375-2560 and the STR was higher to assist the smaller (2.2L) motor off the line.


P.S. The looser configuration of the stock converter caused the STR ratings to drop well below published math. The increased efficiency gained by the tighter clearance in the reconfigured performance converter corrects this equation and brings the finished math to a consistant reading.
