It's really just depends on the dyno, but on the average dynojet dyno maybe close to 450 rwhp

This Mustang Dyno is very picky, as this is the same Mustang Dyno Kyle from 1320Video uses for his Unicorn C5 build and don't think it ever broke 1000whp on this Mustang Dyno.

Mustang dynos usually make even less but it's hard to say since ALL dynos can vary. To be completely honest you should get the whole dyno number thing out of your head. If the car and tune is setup right it will run how it should and that's all that matters. To make 500 rwhp on and honest correctly calibrated dyno you will need better heads than what you have and that's gonna cost you a lot more. No numbers on mine with the new tune and Fast intake but it doesn't matter to me since it runs exactly like it should based on the mods

I'd have to agree with a previous statement on chasing Dyno numbers only paint a small part of the build. I've been told many times that for a 408 mines weak number wise but I have basically everything possible changed chassis wise except K-Member and a couple of things. Point being with the power I'm making you could launch it on the street with only two fingers on the wheel. I've watched too many times these crazy high powered cars brag to everyone they are making 800+ to the wheels, then get called out and have there *** handed to them in front of a crowd by lower powered cars.
