Centrifugal or Screw

[ayabrego]

I am looking into buying a supercharger and was wondering what type would fit my desire more. I will probably go to the track maybe three times a year or so I definitely am not trying to build the baddest race car ever. The car is daily driver and possibly sees about 40 miles a day and some trips out of town. I am looking for possibly no more than 425 horsepower and dont ever really see myself building a motor to hold anymore power. As far as the difference in the two blowers how to do they react differently on the street. I know the difference as in how they work but not how they act. Any help on this subject is greatly appreciated. (take it easy)

well which do you prefer? that instant torque or something that builds power as rpms climb? either way, whatever you choose is more then enough to meet your needs and go past the limits of your stock engine.

 

[classix_stang289]

For the most complete kit out there, Whipple High Output hands down. Enough growing room as well if you were to change your mind about building up

 

[classix_stang289]

What does your vehicle have right now, modification wise? list everything, gears and all. they will play a huge role as well

I just have JLT CAI tune and axelbacks. I just want to make the leap already. I just wish I new how the centrifigul pushes because the vortech system are pretty cheap compared to some others.

(from my research) centri's are gonna build boost depending on rpm, just like a turbo. therefore, you aren't gonna have the crazy amount of torque you would from a twin screw off of idle. as far as daily driving is concerned, you'll have somewhat normal power in normal driving range, when you go to the track (where rpms are gonna be higher) you'll have power. at least that's the conclusion i came to when i decided to go centrifugal. i'm sure in a few years when i get into it more i'll end up with turbos, but i'm in the same boat as you and spent an entire year deployed researching this stuff and these are the conclusions i drew. i wanna race, but i'm also going to drive my car everywhere, everyday

Well both systems will make near the same peak power. Torque and the power band is the main difference. If you kick down to 2nd gear and get on it at 4000rpm you really won't notice much difference between the two. It is from 4000rpm and down that you will notice the most difference. Since the centri isn't building more than a couple of psi of boost at most below 4000 the car will feel more or less like it does now n/a. The twin screw will make the same amount of boost from 2000rpm to redline so your car will have a lot more kick at low rpm's and when cruising around town.

Both systems are good. I don't like the Vortech or Paxton kits out of the box because they use a draw through MAF setup. Procharger has a blow through setup that I think is superior because it automatically moves the AIT sensor since it is part of the MAF and you also can get a blow through setup tuned for better throttle response and overall driveability. Another plus, that I have taken advantage of first hand is that if one of your blower pipes comes loose the MAF will still read the air flowing through the system correctly provide the coupling that comes off is not right at the throttle body. With a draw through system its going to drive like absolute crap till you get things put back together. Not to say that a draw through setup can't be tuned well, they can and are all the time, I just think that a Blow through setup is easier.

If your dead set on not putting anymore power to it the cheapest alternative i think its the roots style M90 from Roush and will put you near you hp goal at the motor, not the wheels.

on3performance turbo kit = good bang for your buck

 

[JoshK]

I choose the on3 kit because of three main reasons

It was cheaper than a twin screw

Seems to come into boost sooner than a centri

Plenty of room to grow down the rode

ps always really wanted a turbo car too

It really boils down to your own personnal preference though, not what someone on here is going to tell you that you may like

 

[bigray327]

Totally personal preference, so don't let anyone tell you otherwise.

I went with a Vortech because my car is a daily driver and I didn't want to be tearing up tires when I'm driving to work (unless I want to). Unless you're going to be running Mickey Thompson tires on your way to work every day, there's no point in having more torque than your traction can handle. Also, a centri with an air-to-air aftercooler is allegedly the most efficient system you can get.

No kidding. I was thinking the same thing. I dont really plan on getting some Micky t's. The most I plan on getting is nitto's for street use only. I figured if I do go with the roots style I will never catch any traction. Good point.

I have always been amazed by the turbo sound and still am. The reason I feel like the supercharger is better for me is because it does not generate so much heat and there are times where I have to drive out of town and I dont want any over heating problems. Also my brother had a turbo on his 95 mustang and set the hood on fire. Not sure how he did it but he said it was because of the turbo. If anyone can convince me that the turbo will just be as reliable as the supercharger please do. I would love to throw a turbo on and not worry. ( I do know the risk of any kind of force induction so please hold it to your self.)

 

[SilentScope]

You won't have overheating issues with a turbo kit. Ask the thousands of people who have them

 

[DKS]

Sounds like you need an M90. Are they still on sale??? That's a hell of a deal. I'm thinking long and hard about using my tax money for one.

I thought about the On3 as well, but I already have clearance issues out here in the country. That's my biggest reason to go with a SC instead. But the On3 is a hell of a deal for the amount of potential it has.

If all u want I 425 then get an m90. If u ever want more, get the vortech. I just put down 486 on 6.5psi with the v2

 

[funmoneypit]

Like everyone has said here, if you really will be happy with the 425 hp, get the M90. Here is a link for one on Ebay: http://cgi.ebay.com/ebaymotors/ws/e...0729457260&viewitem=&sspagename=STRK:MEWAX:IT It is the polished one and a little over $3500. You don't really need anything else with it so it is a great deal IF you won't want more later. Really nice driveability and some good power too.

I too am looking at a Centri if/when I go FI. I like the more linear torque versus the immediate torque.

Good luck with whichever you choose.

looks like I will be going with the vortech supercharger the one that does not come with the fuel management upgrades. What do you all think will be more efficient for fuel? BAP or a pump? what kind of injectors? Anything else you all recommend for this kit. It is also not the intercooled one.

My stock pump was good for 408 rwhp. How high are planning on going with it?

 

[Jucostud]

485 with bap and 39lbs injectors.

 

[ayabrego]

I plan a 450 max no more
