BRAKE stall in not a consistent way to measure your stall converter and has many variables. This method
will be lower then TRUE stall by 400-800 RPM.
What is FLASH Stall?
Flash stall is generally read while the car is in motion. While rolling at a slow speed the throttle is
depressed fully to see where the RPM will flash (or peak). This method will not be true if tires spin or car
is rolling too fast. Due to the turbine already turning in the converter we end up with less torque
multiplication. This will give you a lower stall reading of between 200 and 600 RPM under the converters
TRUE stall in the same application.
Why do I need a custom built high stall torque converter ?
A torque converter that has a part number has many applications. Many manufactures sell you the same
advertised 3200 rpm stall converter for your small block as they would for the next customers big block.
This will always result in two very different stall settings. Do you need a custom built high stall torque
converter? Perhaps you don't, but building the units on a one to one basis allows us to put out a product
that is configured correct the FIRST time.
At what RPM should I activate my Nitrous System
The RPM level is not as important as is the motors ability to rev freely when the nitrous is engaged, I.E. If
the vehicle is in low gear, nitrous can be engaged at any time, but if the vehicle is in a higher gear moving
at a slow speed when the nitrous is engaged the engine will detonate and damage will occur. The same
goes for actual differential gearing.
Moving the MAP Sensor line to Manifold Vacuum
(Does it really work?)
Some folks have claimed that moving the MAP Sensor signal line (vacuum line) over to Manifold Vacuum
generates more HP and TQ. While it "feels" like it, all you're doing is dropping the MAP signal quicker -
causing the PCM to think that it's under a load quicker - therefore adding more fuel and retarding the timing
slightly quicker (yes...timing is retarded while under a load). In cases where a longer duration camshaft
with more overlap (see Poor Idle with Big Cam tip) is present, this does work...but it's not going to
substantially increase HP/TQ on stock cam's engines.
Charging System Upgrade - 1992-1996
If you are running a higher than stock performance engine and/or high powered stereo equipment in your
1992-1996 Dakota, you can replace the alternator pulley on your factory unit with the pulley from a 1997
or newer Dakota (2.5/3.9/5.2/5.9L all have the same pulley on them). We checked the voltage output on a
1993 and 1996 Dakota with the stereo, headlights (with high-beams on), A/C turned on, wipers turned on,
and with the blower motor set at high...voltage was as 12.6-12.8v. With the smaller diameter pulley from
the 1997+ models, the voltage increased to 13.4-13.8v, thus giving you not only more power for your
accessories...but also enough to keep the electronics (Sensors/PCM) at optimum voltage as well.
1992-1996 Alternator Pulley = 2.85"
1997-2003 Alternator Pulley = 2.47"
