Wassup everybody I dunno how many of you follow the protegeclub.com forum but Area 51 is in the mix of building a supercharger for the P5.... They're known for their 7 sec SC300 their website isn't up yet but it should be pretty soon http://www.area51fab.com/ They're pretty reputible and have a supercharger for the IS300

I would definately rather get a supercharger than a turbo for the obvious reasons.
 
Hi Gene,

You gotta forgive me, but I gotta ask. Since I am very very new to this whole mod thing going on, I gotta ask...What are the obvious reasons for a supercharger over a turbo? What are the differences?

My Pro5 is automatic anyway, and by reading the posts on this board, I have gotten the feeling that it really wont help much to do anything speedwise I guess. Someone put it nicely..."all show, no go..." Hahaha, I'm happy with that. I got my other car to drive fast in. But anyway, I really am curious to know what the differences are between turbo and supercharger.

Thanks for all your insight!
 
Well for one thing for a turbo charger you have to be in a certain RPM range for it to kick in a supercharger is on all the time but as i hear with a supercharger on all the time the belts and stuff wear down faster
 
Don't Forget fellas if you're gonna SC or Turbo your car Make sure you strengthen your internals, Valves,Rods,pulleys Beef the internals so it could handle all that boost. or your gonna be Sheet out of luck when your engine blows. Or else you'll be like this guy right here: :mad:

Mainly the difference is that the S/C is a belt driven system, while the T/C is driven by exhaust gases. The point behind Forced induction is to put more air and more fuel into an engine, giving it more power. There are alot of things to look at when T/C or S/C, with the main ones being: Fuel Delivery, Fuel Management (ECU), Exhaust flow, and Internal Strength. It's never a matter of simply bolting on a S/C or T/C and getting huge gains.

The only bad thing about a supercharger on a small engine like the 2.0 is that you will actually have a loss in power at Low RPM's. Being belt driven the S/C benefits on a smaller engine are usually not really useful until up in the higher RPM's where you can build more boost and get a better Fuel/Air mixture. Think of the S/C as something like your power steering pump. It takes engine power to run that pump (belts turning), but the benefits of running an accesory like that are worth it. Well, running the S/C is much the same way, with usually 40% or gains in hp and tq on a stock motor. On a larger motor, like say an Lt-1 V8, enough torque is made to negate the force needed to run the S/C at slower speeds, unfortunately torque is something we don't have much of..

A T/C uses your exhaust gas to spin a turbine and create a certain amount of pressure to push fresh air into the engine. With a T/C you always have "lag time" (time it takes to build pressure to move more air in) which is gonna happen on any car, and depends on the size of the turbo, and size of the engine respectively. The T/C can give phenomenal gains with the proper tuning and precautionary engine enhancements (forged internals, ect.) The power delivery usually comes into effect rather abruptly and builds with engine Rpm.

Anyways, after owning a T/C car (86' Buick Grand National) and a car with an aftermarket S/C'ed car (1992 Pontiac Firebird GTA) I would recommend the T/C. The efficiency, power delivery, and overall performance of the T/C just seemed so much better in my personal experience.

Anyways, sorry this is so long, I am bored here at work and figured I would try and help. I am no expert by any means, but have used both with success and just figured I would share.

Good luck!
 
fastdrvr23,

You are right on about the torque issue. I would love to see the performance results of both a SC and TC on the 2.0L engines.
 
Just a thought, guys, but have you driven a WRX recently? They have a 2.0 like us, but with a TC pushing it to 227 hp. Below 3,000 RPM, there is nothing happening under the hood. I'm completely serious... nothing! It's so sluggish below 3 grand that I actually thought there was something wrong with the car. Above the magical number of 3,000, however, lies an entirely different and wonderful story to tell.
 
I will definitely agree with that. I drove a 5 speed WRX when I was looking for my car. I think the All-wheel drive actually factored in a little in power delivery at lower RPM's. I tried a light clutch slip at about 2500 RPMS or so, and it damned near stalled. At 3,000 RPM's it is a huge difference. It's like all of a sudden the Turbo remembers it is supposed to build boost, and bam! I wish the WRX had a boost gauge, that would help immensely. Anyways, it's all about keeping that thing in the higher range though. I did an all out clutch dump at ~4250 RPMs (with the saleman in the car, :) ) and it pulled like a S.O.B. Enough to pitch me into the seat and quiet the salesman down from his pitch about all wheel drive. They're awesome cars, and with a little tuning would be something to reckon with even in a straight line race (something they weren't intended to do at all). It would have been nice if they'd used the 2.5 boxer engine instead. Oh well...

Oh yeah, about the 2.0 turbo that you mentioned Gene, there is a guy over on www.probetalk.com a turbocharged 2.0 FE3 motor. :) Here's his dyno sheet... Whew.

YOU KNOW I AM STUPID FOR SAYING THIS AND I KNOW EVERYONES GOING TO LAUGH BUT I JUST DONT UNDERSTAND WHY THEY CANT COMBINE THE TWO, I DONT KNOW ENOUGH ABOUT TURBOS AND SUPERCHARGES TO KNOW WHY BUT IT WOULD SEEMS TO ME THEY COULD GO TOGETHER
 
Nice questions and great replies. If and when it does come out just let us know. The website should be up when?
 
steve says:turbos are better then superchargers. steve also says:women find it sexy when you talk in the third person. hahaha.

You could drive around in Antartica and still overheat. ;)

... and I don't think the HKS Meguire's Car ever drives if its both SC/Turbo. They just push it from show to show :D
 
I read in an issue of Car and Driver before about an AW11 MR2 with a s/c and t/c set-up,it's definetely possible, but I've heard it's an ass to make it work.
