Centrifugal Supercharger?

[bathtub.toaster]

Has anyone done this yet? I'm building a turbo 2.3 and I'm just curious if anyone has even tried putting a centrifugal supercharger on one. Would it be easier since you don't have to mess with exhaust manifolds or intercoolers?

Supercharger takes more power to run versus a turbocharger.

For some reason this makes me think of electric superchargers.

But not like this:

If I remember right that's the belt drive units that have a gearbox attached to what looks like the cold side of a turbo? If so they work fine but sometimes they're hard to package... I haven't used one personally but we have at work in the past...

yes....lots of lima supercharged

Prochargers are the worst of both worlds.

You have a compressor that's only efficient & doing it's job during a certain rpm range AND it's sapping HP whenever you're not in boost.. not to mention the cost..

Wouldnt necessarily be easier than turbo either. You'd still need to find space to mount it and make brackets.. plumb the charge piping..

Youd really want an intercooler at anything above 5lbs too.. so consider the cost/gain ratio. 5lbs would be a 25%ish gain.. is that little gain really worth 3 thousand+ bucks and a bunch of elbow grease? I'd say no personally.

Go with a turbo and intercool it if you want more than 5lbs

Direction of rotation as you want, but the air intake and outlet will swap. It has worked no more than 10,000 km, almost new. Car Maker: Universal. Material Type:Steel Aluminum. Material TypeSteel Aluminum.

^^ get one of those.

You'd still have to build brackets & plumb the thing, but it doesn't cost many thousands of dollars and will give you boost throughout the entire rpm range

Mounting a 2.3 turbo setup is the easy parts. Tons of space and tons of cheap manifold options. The expensive part is when it comes down to aftermarket engine management...which you will need for any boosted EFI application.

megasquirt it for the engine management. they have prebuilt kits now days so you aren't soldering a bunch or diodes, resistors, and junk onto a motherboard yourself.

though building it was very interesting. like an adult lego kit but only 500 bucks

I have megasquirt on my 88 turbo truck, it ends up being a bit more than $500 all said and done. For the 95+ stuff it can be tuned via SCT or the like (I used SCT on my supercharged 4.0)

Megasquirt has always interested me, but I have a hard time spending the money AND committing myself to a engineering degree to learn how to program and set the engine up.

Versus staying stock and just plugging the stock computer in place. I know there is not much fun in that, but have you ever drove a vehicle where you did not know how it worked and how it was put together? I rarely have but when I do, it's enjoyable.

Building megasquirt was awesome, tuning sucked and was over my head. I couldnt get it to run but the next guy plugged it in, did something on his laptop for about 2 minutes, amd the car started and drove away.

Pissed me off so much that i dont do any stand alone anymore because i know the tuning is something i cant figure out. I will build one all day long, or buy one with a base tune on it already so its already running

My mustang has a Paxton centrifugal with a safe tune. I prefer it and hate it at the same time. Love it because it's engine driven and wont make boost until 3500 rpm or so. As RPM rises, so does boost. Mine stops at 10ish. I can drive around all day and not spool. No wasted gas. It sings all the time and makes the car very linear to drive. I like the packaging on my blower as well. I also know when the boost is coming. No surprise mid-corner.
I've raced turbo cars for years and prefer them. Once the turbo is spooled, you have most of the boost right away, some ups and downs depending on tune, of course. My car needs RPM to make boost and can get dull feeling if I can't get into boost between corners because of the gear I needed to be in. In a turbo car, you two foot the gas and brake to load it.

I had a 96 Turbo Ranger back in the early 2000s. It had an SVO engine and turbo. Maybe 14 lbs of boost through an always heat soaked intercooler, just pinging it's life away. I know a lot more about them now than then and I sure was a knucklehead. I have blown up a few in my learning curve.
