which is better for the price ?

a vortech supercharger or a rear mounted turbo? on an ls6

**JwMonE99** · 09-09-2008, 08:08 PM

Vortech for sure.
STS is not worth it

**Tman** · 09-10-2008, 04:02 AM

Go with Vortech.

**99 Formula** · 09-10-2008, 01:26 PM

Vortech gets my vote...just cause i like my ground clearance and wish i had more..* stupid SLP exhaust**

**zero_proto** · 09-11-2008, 06:04 AM

i would also say vortech. The money it would cost to get the sts to run like a champ would be a little more than a vortech setup.

**Websy21** · 09-12-2008, 11:23 AM

Vortech FTW, wouldn't waste my money with STS!

**Liquifire** · 09-13-2008, 10:06 AM

wow.........I see who is winning this battle!!!

**cailey37** · 09-13-2008, 11:22 AM

If you threw in say a custom turbo system, or one like APS then I'd say them hands down over Vortech.....but like everyone is saying STS is junk....

Why not a Procharger as a choice?

well im not 100% sure if i want to go forced induction or not yet, and im just trying to get some opinions before i do anything

If you want opinions, then Procharger is the way to go!

thanks everyone i appreciate the help

aps or custom turbo gets my vote, sc robs power from the crank, turbos take what would be useless exhaust and turns it into boost... turbos ftw!!!

The SC may steal HP from the crank, but turbo systems have their own losses through back pressure, especially up top. That seems to be commonly left out when people knock the SC.

The SC setups are more reliable for the long haul, and are very competitive with the turbo on the track, not to mention being easier to effectively and repeatably race.

Exactly, turbos are not "free power". When you think of it in terms of exhaust, just picture removing free flowing 1 3/4" Longtubes and replacing them with extremely restrictive manifolds with a turbine wheel in the way of exhaust flow. Drive the car back to back with no boost and you won't believe the difference in power and torque, especially top end. So you're losing a bunch just changing the exhaust setup.

Then you have to figure in the backpressure created in the exhaust manifold between the exhaust port and the turbocharger. A lot of exhaust gas backs up in there, expecially at high RPM's, where the backpressure is too great to move the amount of exhaust that's trying to exit the cylinders. So there's quite a significant loss there too, and it gets exponentially higher with the more boost you are pushing, since forcing more air in means more air is going to need to be expelled on the exhaust stroke. If you've ever seen a turbo exhaust manifold glowing cherry red you'd know what Im talking about.

The supercharger requires engine power to run, but you can keep your free flowing exhaust (LT headers, duals, ect) and when you're not under boost, you're only losing a couple of HP to turn the rotors/turbine. Not sure of what kind of power it saps under boost, but the newer models are supposed to be quite efficient as far as parasitic losses.

You know...I've been sold on turbos for quite awhile now for when the bank account finally says "Yes! You can finally afford forced induction!"

After reading this though I think I may have to reconsider.
