Congrats those are some impressive numbers for a lil 4.8.

Thanks guys,
Its still hard for me to believe a 4.8 is putting those numbers down with LTs ORY and a blower. Kinda makes me wonder what the boost psi is?????

That sounds like a perfect dd! The advert did say 450hp, although on a 5.3. I am very impressed with the kit. I bet your boost is about 10lbs. Still waiting on 6.0 results....

Well that's freaking killer power out of a 4.8....seems these Roush SC's were the real deal and make every bit as much power as their Magnuson counterparts...for 1/2 the price.

Yes dd/SLEEPER! LOL
I might grab another and just sit on it untill I start another project or the price is right
win win I think. I got mine from dyno-dan.

Now Im curious what my 2004 4.8 will do. Just got my LT's in and gonna put them on and my 3.3 pulley for my radix (down from a 3.9). Getting a tune as soon as its on. Only have CAI LT ory and full corsa running at 9.5-10psi. Im gonna post dyno sheets as soon as I get them. Im only thinking Im gonna get around 375 at the wheels, but I guess Im just a pessimist...

WOW after seeing this thread kinda makes me think about one of these kits. Its almost one of those to good to be true kinda things. But with proof.

If you do some searching of my threads from 05-06 you would have a good idea of what yours would do. I ended up with 445/489 I think with a cam, 11.5 psi boost, LT's, larger heat exchanger and meth injection.

The 442/407 is awesome. Shows how much better the new tvs really is.
