4x4 dyno

How do people get a vehicle dynoed if its all time 4wd? I can't turn off my 4wd and make it 2wd. I'm unable to find a place that has dynos for 4 wheels. How do ppl dyno their trucks with 4wd?

A buddy of mine entered a local dyno competition with his mud race truck. He runs a aftermarket transfer case that's all time 4x.

The frt driveshaft was running through a tube to contain it and would have been a pain to remove it. We just pulled the front wheels off and set the axle on 2 wood blocks and strapped it down good.

Blown 500" ford motor on methanol. Worked perfect.

Having a tough time finding a dyno shop thats willing to dyno an 8000lb truck and remove the front drive shaft to do it. Now I wish I had a 2wd option on my transfer case.

Calibrated Power Solutions (Duramax Tuner) has a 4wd dyno. I have dynoed our truck there like 4 times through the years and always in 4wd.

Best bet is just remove the shaft. Mine is the same way. Why canít it go in 2wd at that weight anyways

Any intelligent fool can make things bigger and more complex...it takes a touch of genius- and alot of courage to move in the opposite direction.
