ok, to me this is a good question I have to ask everyone. First if I have a 2002 Mustang Gt. Everyone says the max RWHp for stock engine is around 425-450. OK are u talking about a dynojet, which isnt true rwhp or a dynomite which is true rwhp, because it has one wheel for both rear tire that contact on it? this is important, because I need to know? The reAson, because the dynojet will give u more like 20-30 more rwhp which isnt accurate and I dont want to blow my motor, because I will be using a dynomite, which is accurate. So what I really want to know if when this was tested, was it on a dynojet or dynomite?

 

Well Ford rates the rods at 450 hp. Which means flywheel hp. so between 360 and 390 rwhp tends to be safe for a while.

Also there is no True rwhp any dyno will read differently, and Dynomite and Dynojet are only two types of dynos, there are also Dyno-Dynamics, Mustang Dyno

 

THe one I use only has One wheel about 6-8 feet wide.. I have heard that it is pretty accurate. But I new to this dyno stuff, so I need to learn. Well I guess I will be in that range with the t-trim using a 3.60 pulley, because it flows 2-3lbs. more then the s-trim using the same pulley.
