: GMPP Announces LS9 Supercharger Kit

I saw this today. I know our cars are right up there in power, but wouldn't it be cool to open the hood and see a LS9 supercharger :worship:. Might be kind of pricey at $7500.00

I think for $7,500.00 you can make more HP without adding an LS9 Supercharger Kit and have a little left over for some other mods.

They can be had for $6,400. For a larger supercharger and better intercoolers might be worth it.

better do the bottom end before you screw that 2.3L s/c on there......

I'd rather have the 2.3 + better intercoolers then the stock one when run at equal boost levels.

Cam, pulley's, T-stat, headers, tune and OEM driveability...700+ at the fly wheel. Makes me want to get started.

I believe that if you want to build 800 plus crank HP with less boost then maybe the LS9 SC is worth it. I got close to that with my mods, but my wife and common sense said it was time to stop. The V is my DD.

If I were to go higher, I'd probably do some bottom end reinforcement then get the LS9 SC.

The ls9 does not have better intercoolers. They are too small because the packaging needed for the corvette hood limited them. They need to be double in size to equal the stock lsa intercooler.

^ it sounds like the Ls9 blower is seriously restricted in power by the intercooler size.

07-18-10, 11:09 AM
Yes, Raz you are correct. As lingenfelter proved on thier drag camaro, They made a double intake that held 4 intercooler cores and picked up ALOT of boost AND power from just that change.

Fastlaneinc. says they put a LS9 supercharger on the V if you look at the video it still looks like the stock supercharger.

YouTube- Cadillac CTS-V with ZR-1 Blower Upgrade (CTS-VR1) (http://www.youtube.com/watch?v=wPPLjTdw5TQ)
$4700 for the upgrade. Not terrible, I suppose. And you can sell your current S/C to recover some of that... I like the idea of more power without significantly raising the boost.
Does that video say it has H/C too?

what other mods need to be done to accept the ls9 supercharger? injectors etc?

07-19-10, 07:15 PM
I would totally rather do that then boost the hell of the car. For $4700 that dude has 600RW? wow...That's pretty good.

that 130 hp is with heads,cam etc. what can be expected with just the supercharger upgrade?
