Laser red Bread Look Ma! My First Post! Join Date: Jan 2008 Posts: 1	Best Supercharger? Which supercharger would be best recommended for my GT? The Kenne Bell or the Vortech? Leaning towards the Kenne Bell but I want to keep my options open. Any suggestions. My setup is pretty much stock. Just some JBA shorties and a JBA h-pipe to match.

definently +1 on the procharger, the new paxtons are also damn good blowers.

How you oil it don't make or break how good it is. __________________ *Gone To Basic Training*

I dont understand. Why is the Vortech more efficient? When you say effiency.. your speaking in terms of? Im curious.

the centri's blowers make less heat than a positive displacement lower, which means they are more efficient.

The way a twin screw roots type blower like a Kenne Bell makes power is differant from a vortech or paxton. The Vortech and paxton have a linear boost and power curve. They make more power the higher your RPM. But at low RPM, they make very little torque due to their design. The roots type (KB) builds boost much lower in the RPM than the Vortech, it will make slightly less power at peak than the Centrifugal Supercharger (Paxton\Vortech) but it makes a lot more torque through out the spectrum.

Okay, so in terms of heat or tempurature, your saying the Vortech is more efficient? That seems odd to me. Anytime you compress air, you build heat.. if both superchargers move similar amounts of air, and have the ability to compress the air to within a certain level, the heat production will be around the same. The benefit of some superchargers, is an intercooler (you know that already) The KBs are intercooled. Your telling me that a non-intercooled Vortech(if thats the system he decided to you use) is more efficient with heat production, than an intercooled KB?

ModMustang97GT Enthusiast 1997 Mustang GT Join Date: Aug 2007 Location: Seattle, WA Posts: 623	Because of the location of the Vortech compared to the KB, the heat will be greater at the location of the KB than the Vortech. But what you are not taking in to account is that the air from the KB goes straight in to the engine, rather than having to pass through your intake manifold and the piping to the TB. The only really important differance between the two is their power curves, and what type suites you.

Why is the temp going to be higher with the KB? Because the air is being squeezed just before the intake port? It passes through an intercooler before it ever makes it to the port. Those air-to-water ICs do a rather nice job of bring down intake temps. Even besides that, the Vortech will squeeze the air just the same, and produce the same heat at the compressor. Without an intercooler, the intake temp will be very similar. __________________ Definition of Fast? I'd say thats good enough. NMRA Outlaw 10.5 Season Opener 2008 Photo courtesy of - Yours Truly

a properly sized centri that can move more air than a twin screw is goign to make less heat. and a vortech V2 is capably of more airflow than a 2.1L KB, therfor is going to make less heat per PSI.

also, the vortech;s can be run with the paxton air to air IC system which is even more efficient, and less restrictive than the vortech aftercooler system.

The centri's also use an impeller to compress the air and this is more efficent than the screws or roots. But your best bet is still a procharger IMO. __________________ *Gone To Basic Training*

+2 on the Procharger. But the KB is really good as well. Research twin-screw superchargers vs. centrifical superchargers. Their boost curves are very different.

Considerations: Is your car a daily driver? Will anyone else other than you drive the car? Will you be driving the car in the rain or snow?

A twin-screw reaches maximum boost at somewhere around 2,200 rpm. It has a lot of low end torque and some have said it hard to handle in bad weather. The centrifical supercharger builds boost gradually. Mine is 1.8 lbs at 2500 rpm and 8.9 lbls at 6,000. My wife seldoms gets above 2500 rpm and I keep it below that in bad weather so the car behaves pretty much stock. When I want the power its there.

there are many reports of that vortech aftercooler becoming inneficient after about 15PSI. we're going to be pulling the one off my friends fully built T-trim 99 cobra and doing the paxton air to air setup very soon.
