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?

Like I said I dont know what all else was done to the car it might have different pistons crank rods etc.....

The guy that done the work on the car has a old 69' chevy truck when he told me it ran 10's in the 1/4 I told him he was full of ****.

To make a long story short this guy shut me up when he ran a 10.6....

This guy knows his stuff he built a IHRA pro stock car from the ground up.

They ran the 190mph in Denver City TX..........Anyways I seen the dyno sheet 480RWHP...........If you knew this guy you would know that he doesnt make stuff up...............The IHRA car that he built runs 7's "I seen it"

The LS1 is up around 350ci there are 331's and 347's that have more power than 480RWHP Naturaly aspirated.

Displacement isnt everything

Thank you for stating your opinions in a non-hostile way, it was nice for a change..............later
