DODGE STALL SPEED CHART:
15 Blade Stock Stall: The most versatile converter offered. It is loose enough to spool most turbos, in most elevations and climates, while maximizing low end grunt and keeping the torque converter tight enough when the turbo lights and horsepower is being made. This converter should go in trucks that TOW and WORK HARD. Approximately 200-400 RPM lower than a stock converter.
This converter works well with: •Stock turbos from 0 to 11,000 foot elevation •2nd generation dodges (0 to 4,000 foot elevation) with stock to 58mm turbos •3rd generation dodges (0 to 4,000 foot elevation) with stock to 62mm turbos
This converter works well with: •2nd generation dodges with 60-62mm turbos @ 0 to 4,000 foot elevation •3rd generation dodges with 63-71mm turbos •0 to 4,000 foot elevation with 67-71mm turbos •0 to 11,000 foot elevation on 63-66mm turbos
10 Blade: When the tightest converter is needed. Not many uses in 1994 to early 2007 dodges. This converter is perfect for lowering stall speed and maximizing torque output in 2007.5+ dodges with a 68RFE transmission. This converter is approximately 600 to 1,000 RPM lower than stock.
This converter works well with: •Stock to 57mm turbos in 1989-1993 dodges with no lockup •works very well with 6.7 Cummins in front of 68RFE transmissions •turbos from stock to 64mm •the low first gear in the 68RFE and the added displacement from the 6.7 help light turbos very well, the 10 blade stator is an additional $300
TURBO INFORMATION: •All turbo sizes mentioned were the compressor size •Exhaust housing size and exhaust wheel size make a difference in turbo spool-up as well •The compressor is the largest factor
FREQUENTLY ASKED QUESTION: How do TWIN turbos fit into the equation? Twin turbos only spool as fast as the size of the small turbo - and even a little slower than that. Example: A 62mm and a 74mm turbo used in a compound set-up is going to be equivalent to the spool-up in a 63mm single, BUT they make close to the same power as a 74mm single. Also, elevation makes larger turbos even worse for spool-up. -- What works at 0' elevation, 2,500' elevation, and 4,000' elevation are all different.
See the chart below to help determine what stall is right for you.
