WHo has 300whp and what do you have

^^^ Very informative! So if I'm reading this correctly, Mustang dyno's may read high, low, or accurately, whereas Dynojet's are more comparable from dyno to dyno...

IIRC, stock 370Z's hit the dynoJet's at around 270-275 whp, which is approximately 19-20% drivetrain loss. That makes sense to me.

Unless you're in the 1000 hp club, and at a dyno day to show off grotesque power numbers, I think it's important to remember that the dyno is ultimately a tool for tuning.

sounds about right, my baseline was 277rwhp, dynojet SAE C.

^^ Yes sir dynojets are all calibrated at the factory and the shipped out to the shops, and there is no adjustment parameters for the shops. I really like both the dynos alot, and give custmers the option to decide which one they want. Usually they just ask us what is best and we lead them in the right direction. Also our dyno jet is only 2wd so when it comes to the AWD cars they all go on the mustang. We just did a G37X with all the bolt ons and we ended up with 305whp on the mustang...

This is why I've said elsewhere that Mustangs and other load bearing dynos can either break hearts OR lift spirits -- there's too many fudge factors.

This is also why I pretty much only go by dynojets for determining power figures.

Load bearing dynos are better for tuning, tho.
