custom supercharger project

[Paul Ruebens]

Thanks Mike....I feel like I'm carrying the torch here...I"m just trying to clear up some falacies.

The boost comes on in such a manner that it feels like a turbo spool, but thats not the case. It's a direct relation to the rpm. A turbo can be at full boost as early as 2K rpms... a supercharger will hold it's boost (under its maximum setting) at a given rpm assuming the pulley is sized correctly.

There is a thread over on Protegeclub by Roddimus Prime on his attempts at this project, if you're serious you should talk to him and also look at the two kits ( one of which works, the other which would require modification ) that are already available, use roots type blowers ( no oil/coolant lines needed ) and don't lose the factory AC or PS. Only the strut bar and Cruise control would be affected.

The one that works is from Taiwan based AAI

And the one that's close is from Thomas Knight and is for a 626 2.0L engine. Its our smaller engine bay that creates the problem.

The expense of these kits is in the manifold, which needs to be heavily modified to fit the blower on it. If you using a Centrifugal, and don't want to lose PS or AC, its going to need to be mounted on the Drivers side of the engine bay, and shaft driven from the pulley side. Not an easy task, and the intake tubing and exhaust woudl also be very complex.

I'd like to go SC just to be different, but it would sure cost a bundle.

 

[Paul Ruebens]

I don't believe the location of the blower itself is the problem when retaining the ac and ps. The problem is where the pulley is going to go. Take a look below your PS pump and look at the huge bracket/tensionor and then just using your hand measure how much space you have between that and the AC compressor.

Cost should be right around a similarly powerfull turbo kit.

 

[03P5]

I doubt the cost of a one off is going to be right around a new and complete turbo kit. Maybe using a used blower, and fabing up your own pulleys/brackets and piping.

 

[Paul Ruebens]

you'd be surprised how cheaply you can get things when you know people and make phone calls.

The power comes on differently for roots and centrifugal blowers.

The dyno curves of every centrifugal blower I have seen is top end power. This car does not need top end power.

It's not a fallacy, it is a fact...

 

[Paul Ruebens]

did you just say the protege DOESN'T need top end power?!?!? Will you sell me some of what you're smoking?

Are you racing the car at track events?? Seriously, are you?

The power curve is pretty decent stock. Adding more top end power is worthless on the street. Moving the whole curve up and possibly shifting it slightly up is beneficial.

Having stupid peaky horsepower via a centrifugal blower is rediculous.

 

[RyanJayG]

I have to agree... people always neglect area under the curve for a dumb peak number.

 

[Paul Ruebens]

where are you guys getting ANY info on a protege blower's horsepower numbers or power curves?? You guys are speculating. You assume that a centrifugal blower is going to cause a power curve different (negativley) than even a turbo car.

That's so funny. I'd bet a dolar to a dime a supercharged protege engine would have a flatter power curve than a similarly boosted turbo protege.

Have you guys even seen the dyno graphs from ATI on their 1.8L honda kit? It looks IDENTICAL to the NA dyno only about 80hp higher. That's a centrifugal blower go ahead and explain it's power curve.

 

[Paul Ruebens]

obviously you're not refering to me. You couldn't be because I've mentioned nothing of peak numbers. Who are you refering to?

read the lasst part of stutters comment right before my post.. that is what I was commenting on.

 

[Paul Ruebens]

Stutters last post was a semi-asault. It was also pointless. This guy is just making a supercharger for the car and everyone seems to have something negative to say.

It's always easy to criticize when your hands aren't getting dirty and you're not spending your money. I suggest the nay-sayers and haters shut-up and pick up a wrench to help this guy out. Maybe we can still salvage this thread and others like it or run off yet another tuner bringing out products for our cars.

Anyone know the full effects of not having power steering?

 

[dominoy2k1]

i dunno but i wanna see someone run a supercharger. i love em.

 

[Paul Ruebens]

dominoy, go check out pclub.com they're keeping up on it pretty well. I've talked to that guy a few times and he knows his stuff.

 

[03P5]

I'm sure you can make the calls to get a supercharger for cheaper, but custom fabbed brackets to hold the charger itself and the pulley/shaft aren't going to be cheap. If you have the connections though, more power to you, get on it, I want a SC on a car now!

I checked and although there is some room down near the PS pump/pulley, there's now way a centrifugal and its intake/exhaust plumbing are fitting down there between that, the exhaust and the radiator/fans. Its going to have to be shaft driven or your losing something from that side.

 

[Paul Ruebens]

yup, he said the ac was going. With the compressor and condensor removed there is plenty of room. You guys should talk with him about it. Seriously, he's got it all figured out already.

yeah its a b**** to steer when u need to turn sharp.. as long as ur in motion its not that bad for regular driving, but for low speed turns or sharp curves.. its a pain. i hate it when a car comes in our shop cause the power steering went out.. its a pain to manuaver in.

the plus is that ur will get good upper body strength after a while...

Ok, you know I talked with Area 51 back when I wrote my article in GRM about the Protege. Back when Wings West first built their show car. Back when it was going to cost around $5000 to get one those kits. I saw the dyno curves of that particular blower. And guess what...

The power was up top. Exactly where it does not need to be for a daily driver.

Compare some more apples to oranges too. You are not working with a Honda motor...
