dyno curves etc; 407 to 476 with a tune


KCMO-GT500

Recommended Posts

Interesting, because the GT500 rep told me in April a dead stock GT500 with just a tune will pull 475rwHP! So far everything he'd told me pretty much has panned out. Also said they bench dyno'd with headers, 50% oveboost, tune and got near 650crankHP. That'd be, what, about 550+rwHP = another 75+HP over stock? Not bad!

 

He didn't say specifically how they overboosted it, but it was the stock s/c with different pulleys -- which/where I do not know. As FordGeek has poionted out, not much room for pulley changes.
