I've got one concept for you. They were playing dyno games with you, which is why the numbers are so high. Apparently Swanson is one of the best in the industry because he can get huge numbers (one's that don't exist) by playing with the parameters on the dyno. Stock 5.0's put down between 170rwhp and 190rwhp. Sometimes a tick more for the SD cars. Most are between 175rwhp and 185rwhp. 190rwhp is 230hp at the crank. A Cobra puts down 220rwhp. 405rwhp???? So he's making 490hp at the crank. That's a 10sec capable car dude. He shoud be trapping 125mph.
360rwhp, LOL. Dude, that's 435hp at the crank. A 6psi blower will NOT support that much power. It doesn't have the capability of flowing that much volume, regardless of state of tune. Look at his trap speed for cryin out loud. 110mph? He should be closer to 115-118mph with that kind of hp. Not only that, but his intake, and his heads are superior under boosted conditions than an HO intake and ported E7's.
The claims that an S trim can't make power? I did't make any such claims? Vortech, you know, the manufacturer of the unit. The people who did all the R&D on the unit. The people that spent millions to bring the product to market. The one's that want their product to perform as best as possible. Those are the guys who said up to 126hp from 10psi is what you should expect. I would certainly think they know how to setup their products, and how their product should perform.
A 347 stroker, say with TFS heads, a Holley intake, and a TFS #2 cam or so is going to make about 400-425hp. That's about 330-345rwhp. So, 350rwhp is more than a well built EFI 347 stroker. Where do you think all this mega HP is coming from?
An intercooler adds a lot of power, even on a stationary dyno because it cools the intake charge. Even if the car isn't moving, you've still got air being cooled by heat dissapation. Any dyno tuner worth his salt is going to have fans blowing on the front of the car anyway. Should have a pretty decent breeze, enough to evacuate hot underhood air.
