Dyno Frequently Asked Questions
Should the torque converter be locked during a dyno pull?
Our TCC's are very small and should NOT be locked up at WOT if your 3800 FWD car is making good power. We've heard that some of our competitors do this on a regular basis to increase their WHP numbers by approximately 5%. As an example, if your call pulls 383 WHP on the dyno, this will equate to approximately 404 WHP with the converter locked.
Does it matter which gear my car is dynoed in?
Some people claim that dynoing in second gear will make the dyno record higher numbers because the engine can rev faster. Others claim that dynoing in third gear artificially inflates the numbers. Both theories have proven to be false on every car we've tested. The dyno automatically measures the length of time it takes to accelerate a fixed load, and compensates without final drive gear or transaxle gear being a significant factor.
Every comparison we've done showed numbers within 1%. This means that on a car with 300 WHP, the dyno numbers were within three (3) WHP whether the dyno was done in 2nd or 3rd gear. Also, in some tests the second gear numbers were slightly higher, and in others the third gear numbers were slightly higher.
We recommend dynoing in second gear whenever possible for four reasons. First, it doesn't take as long, so it's less stressful to your engine. Second, you'll experience less heat soak on a non-intercooled, supercharged engine. Third, you'll be less likely to experience a fuel starvation issue at some speed you might never hit in real life (i.e. 140 MPH). And fourth, you won't run the risk of hitting a speed limiter (typically 108 MPH in third gear on many 3800-FWD vehicles with stock PCM's).
