Sorry dude but you are wrong I think $3,500.00 Lingenfelter heads is were all the power comes from. He will probably make around 600 hp on the bottle.

We are not talking about ricers here these guys are serious drag racers and go to the dyno all the time.

I'd bet money he didn't make 480rwhp on a stock LS1 shortblock with Lingenfelter heads, cam and an LS6 intake. Similar cars are making from 375rwhp up to ~430rwhp.
There are very few LS1 cars over 450rwhp NA, and most of them are big bore, or truck blocked motors.
For example, NineBall is running a very seriously developed MTI setup with a 382, stage III heads/cam, LS6 intake and all the other goodies...he's dyno'ing 455rwhp. Rapid Motorsports did a 427, solid roller LS1 iterative that made 481rwhp/547rwtq through a TH350...pretty "on the edge" for a street going LS1 car. There are also a few 42x motors that are in the ~475rwhp range.
Maybe with a 422 or one of the other large displacement motors he'd hit 480rwhp. But a set of Lingenfelter heads aren't magically worth 50-75rwhp more than a set of ARE's, MTI's or others.
I'd believe that the car made 480 at the flywheel, after adding back parasitic losses (that would put it in the 415rwhp range), but 480rwhp I seriously doubt.
All I'm saying is he didn't make that power with just those mods. If he hit 480, he did it with more cubes, or he did it with dope (although that would be a small shot on an LS1...they love spray).
BTW-How do you know it went 190mph?
