Twin Screw supercharger debate
I thought I'd start a new thread and see where it goes, since all the supercharger talk is scattered lets try and see if we can condense it to help people make an educated decision when that awesome time comes to order some boost.
Like many out there I am going to purchase a supercharger for my 06 GT. The problem I am facing is there is not a lot of good information out there from people who are actually using them. My main concerns when choosing a supercharger are:
Power to boost ratio
How easy it is to upgrade and TUNE
Customer service of the company
I have 3 that come to mind right now
KB which is a 2.4 Autoroter
Whipple which is a 2.3 Lysholm
Saleen which is a 2.3 Lysholm
Advantages to each:
KB Billet construction, oversize bearings, lower discharge temp, good price
Whipple Highest advertised HP numbers HT0 plugs supplied, largest MAF sensor (95mm)
Saleen Same exact compressor as whipple + you can use most aftermarket CAI like JLT and MMR
Disadvantages to each:
KB Have heard bad things about customer service, Have to cut car to make install their CAI
Whipple Expensive, hard to find
Saleen Expensive, have heard the intercooler is small, plastic intake manifold, pulies only available from JDM for now
Please If you have installed these superchargers on your car comment on your gains, and your install. I want a blower that is: reliable, easy to tune for future upgrades, and puts out.
If you can think of anything to add go ahead, I have no problem being corrected if I'm wrong. Keep in mind this thread was created to help people choose a positive displacement supercharger. Now, lets spill some knowledge and help out.

RE: Twin Screw supercharger debate
i am not saying any of you info is incorrect but the whipple s/c can be purchased from lethal performance who is a site sponsor and considering is is the most complete kit i dont feel it is very expensive, especially when you compare it to the saleen.
that said the whipple has not been out long enough to go through the paces to see what the actual downsides are. lethal performance has one installed on their car, other that them i have heard of no kne that has one installed. i do know of a few that are on the way though, i am anxiously awaiting somereal world numbers from those who have them.
for info on lethals setup contact boostang on MF.

i would jsut install a centrifugal style supercharger.. such as procharger or vortech
i would get hte procharger system because it has a self contained oil system.. so you dont have to tap into the block to provide a oil feed for lubrication.. just change your superchrager oil every 2nd oil change.. its real easy to do too!

I'm debating Whipple/KB for my eventual install... I just don't want to spend Saleen money.

I have to say that my dealings with Kenne Bell customer service have been nothing short of top notch. I made changes to my order, requesting a polished manifold and blower and upgraded tuner. They accomodated those changes for me and promptly responded to me on my cell phone.
I used Kenne Bell parts when racing my Buick Stage 1 in the seventies and the quality of their research and products is second to none.

1. The fact that you consider it to be an advantage that you can use most aftermarket intakes is bunk. Nothing like dropping 6 grand on a new supercharger only to turn around and drop another 500 to 700 on yet another car part. Oh, and if you had one left over from before makes no difference either, you get to spend it on the dyno tune. And the guy better know what he is doing considering most CAI's have a different MAF and airflow characteristics. Getting the CAI in harmony with the sc will keep you busy for awhile. Sounds like a nightmare to me. KB system already has a real CAI in the front fenderwell with a 90mm MAF which will top out at 550rwhp (just the MAF tops out at 550, the supercharger is good for 850hp). Will be needing a new bottom end, injectors, etc., before you get over 550rwhp anyway.
2. Cutting the hole in the fender was more like "widening the hole in the fender". The hole was already there, just made it bigger with tin snips and a dremel.
3. The HT0 plugs are recommended and not required for a KB system. You can regap the stock plugs. The tuning on the whipple might be running a leaner AF to squeak out more power and needs a colder plug.
4. You have to use KB pulley's on the KB SC, no aftermarket.
I should have some specs concerning the Volumetric Effeciency of the Whipple and the KB in a couple of days. Can't find anything on the Saleen. Hmmmmm. I will post them when I get um.

About the KB cold air intake. That is the one thing that I do not like about their system. I have not seen it installed but I live in Florida and in the summer we get quite a bit of rain...not to mention hurricanes. I know that on other cars with cold air intakes in the fender well puddles are always a concern.

I don't think that the plastic manifold on the Saleen is a dis-advantage. It may even be an advantage! Plastic is lighter than aluminum. Also, it doesn't conduct heat very well, which helps to prevent heat from the engine from warming up the intake air. Someone probably got it in their head that plastic is "weak"....but think about what the manifold is actually doing: even at maximum boost the pressure is what, 10-12 psi? Shake up a 2-liter of coke and you've got more pressure than that--and the coke bottle doesn't rupture despite being extremely thin. I wouldn't worry about the strength of the plastic manifold.
