... So Spike mentioned the other day he was watching Mad Max, and that got me talking with him about the supercharger clutch and if it would actually work or not.

This thread is for those unusual engine ideas you may have that you'd like to share... And yes, you can even talk about DEI as long as you finally understand IT JUST DON'T WORK LIKE THAT

Anyone know what my avatar is?

Mr Twisty · 11-23-2009, 06:13 PM

If you've never seen the movie, MAX had a clutch setup on his blower so he could turn it on and off. That's basically where we left off with our discussion, is it feasible?

A clutched blower is possible, but in practice would probably be less effective as you would have to have enough clearance for air to get around the compressor when the blower was off. Your avatar looks like a constant pressure variable displacement hydraulic pump. Just a guess.

That's part of what we discussed, he'll be in here eventually and can tell you about his dual intake idea.

Mercedes Benz Kompressors have a clutch.

I suppose with intake runners like a Ford 3.8 uses, you could run a seperate inlet path with a blower. Since you only need the blower occasionaly, it could help reduce parasitic draw. With the clutch controlled by the MAP sensor, you wouldn't even need a switch.

Cool, I didn't know that. Bro's wife has the little roadster, I'll check it out next time I'm over

Parasitic loss would be the big draw for it, just below the 'cool' factor... Gotta have a switch tho, for showing off in the parking lot

How about seperate a/f tables in the ecu? Would it be necessary? If the blower was always switched at a certain load, I would think it could be tuned, but the switch idea probably complicates things.

derklug · 11-23-2009, 09:22 PM

Run a MAP for blower on and off, and MAF for A/F. And yes, it would have to have a switch to overide the MAP. An engineer once told me that the auto/sport switch on auto suspensions was put in not for functionality, but because the focus group guys wanted it.

Ogura clutched superchargers...

Only thing better than a switch is a knob that goes from 1 to 10 with an 11 in red

New GT500's come with the supercharger off from the factory. It is tuned to dump any boost out the bypass until the new owner puts a number of miles on it or a couple consecutive starts.

No 11 in red, just an extra click

When Isuzu came out with their turbo I-Mark, it limited boost untill you had 3000 miles. Owners used to come in and say that after their first oil change the car just woke up.

Interesting, but I want to see the clutch kick on and off

The same as the GT500 setup most likely?

I can see how this setup would work great on a marine application with a planing hull... Use the torque to get it on plane, then kick off the compressor to cruise.
