my idea for a flex-fuel 200

[SVO42]

I came up with this on one of the many nights I couldn't sleep. Anyway, I've always wanted an I-6 Mustang Capri ('79-'82, T-top preferably) and came up with a neat package. It would have to run either E-85 or straight gasoline, with only a minor amount of a mixture. Anyway, here's the plan:

9:1 CR 200, forged pistons
Weber or Holley 2bbl carb
centifugal superharger

The basic idea is this: when running ~105 octane E-85, run the supercharger somewhere around 10 PSI. If in an area without E-85, take the belt off the SC and slap a regular air cleaner on the carb. I'd use a MSD 6BTM box. The best course would be to dyno tune for each fuel and note what carb jets, mixture, ignition timing, etc. need to be. That way, just take less than a half-hour to convert the car.

I'd love to do this someday and otherwise keep the engine bay as simple as possible so as to not detract from the beauty of simplicity of design of the inline six. 8)

That's kinda like my plan, only mine involves less work to swap between fuels... I plan on running a turbo, with a stand alone MegaSquirt FI setup. That way, when you need to run cheap gas, all you do is plug in your laptop, or palm pilot, and change the fuel and timing map, and turn down the boost via the boost regulator. Less than 10 minutes. Good luck!

Can't you just set up a toggle switch to change maps with the megasquirt? I haven't looked at it recently but that's a feature with most standalones (that cost five times as much :roll: )

Why would you not just put a clutch pulley on the supercharger and engage it electrically? Way better than offing the belts, in my opinion. Ever seen the movie Mad Max? Good luck.

Oh yeah, I totally forgot that Eaton makes a supercharger with en electrolically controlled clutch to engauge and disengauge the pulley. Comes on 98-03 Mercedes "Kompressor" cars.

Here's a new reman one on ebay. It looks like a good deal!

There's a significant core charge on top of their "Buy It Now" price. How cynical is that?

Don't buy it now, just bid the minimum bid, and win it.
