Re: Water injection nozzle

Or you could build a small bubbler (waterpipe styled provision) and let the engine breathe part of its air through that. That way, you will get a very fine mist. It WILL evaporate the methanol first though, so not suitable for water-meth mixtures.

Re: spider Bikish thingish that needs a diesel implant

This needs to become a five-seater, all seated one behind the other, a là Twizy, and a roof, again, like Twizy. And yeah, a diesel would be in place.
I was waiting for something like this to come up for years.
Cool machine.

Re: Honda Rebel Kubota

On the water injection thingy: If you cannot inject an amount low enough with what you have tried so far, maybe you could use a small carburetor or a bubbler ("water pipe"), use a really narrow hose to connect that to your air filter housing (will need own little air filter). Connect throttle body w...

Re: Husqvarna supercharged 418 build

Hey Otto! Little question: When you decided to supercharge instead of turbo, have you also thought of using the old petrol engine as your supercharger airpump? I mean, instead of straight-shaft cylinder off, you could have welded the ports shut, poured some 4stroke oil into the crankcase, and replac...

Re: DIY bang-bang on turboed singles?

If you open the exhaust valve very early then you're just reducing engine crank output to drive the turbo instead. This is a much less efficient way to extract energy from the fuel so your fuel consumption will rocket. Not quite. See, once the turbo is up to RPMs so the boost is at a level that tur...

DIY bang-bang on turboed singles?

Good time o'day everyone! Another stupid idea incoming. As we all know, our little industrial singles are hard to get a turbo to function on due to two reasons. One is pulsations - a properly sized plenum chamber might mitigate this. The other one is the insufficient gas flow available: There are fe...

Re: 15 more MPH

You also need extra air for that extra fuel - whatever it may be, so only really useful if you have a turbo or supercharger in the first place. If you did then why not just ramp up the diesel rate to use the extra air? LPG is popular because it means you can leave the standard injection system alon...

Well, the package would be far more neat and acceptable for longitudinal mounting if it only had the CVT, sans gearbox.
