Who's supercharged?

[hundhaus]

My Callaway Denalis 6.2s are running Eaton 2300cc TVS rotor pack super chargers with 3 intercooler chambers which means much cooler air intake at the heads.

yup
they use a whipple 2.9 (stock pulley), where as callaway & others use a tvs1900.
they will also do a bit more tuning.

also keep in mind this is HP @ crank, not tires. they rate HP just like manufacturers.
so we are really only talking 20-30 HP diff

henn - 508 (whipple 2.9)
calla - 480 (tvs1900)
linge - 475 (tvs1900)


now once you start doing supporting mods...this is where huge HP gains/differences can be made/seen.

That's good to know. I pretty much assumed that the Hennessey numbers weren't talking about HP at the wheel. Still I would have bet money that the 5.3L was only good for 450 to 475 max with only bolt on mods. I just crossed 5k miles on my 2016 Tahoe. My plan was to wait until 10k miles and then try to get a feel for exactly how much my dealership will let me get away with. With any luck, I'll be calling Whipple as soon as I recover from all the Dinan mods on the wife's BMW.

I'd stay away from Hennessey, he jumps into forums from time to time and really shows his true colors

I have heard that before. What exactly does he say?

You are good to go much higher. I was running over 550 on my 04 5.3L. But you are correct, with a 5.3L, no need to go larger than the 1900.

I dream of yanking the heads for a little work orca set of drop ins and possibly a cam when I do my supercharger. I figure with so much off the top of the motor this is a perfect time.

Just trying to find a cam that will give a decent bump yet not freak the tech out when come smog time in a few years.

@JennaBear why don't you guys list a blower for my 2002 Denali? All I see is 03-up.
