It doesn't sound so advantageous at all. But since you're going to ride at such extreme altitudes, turbocharging is a very sensible option.

So not advantageous, but sensible. Mmm...

Not advantageous to limit its boost to use it just as an "altitude compensator" when you can go a little further.

I see. I wouldn't mind going a little further, but I wouldn't want to go so far that for one, I'd have to redo the who thing with a bigger injector, new ECU and have to figure out all my own spark and fuel tables, and two, possibly have to get custom forged rod, crank, and piston and who knows what else.

But if I did go the turbo route, maybe adding a bigger injector and a new ECU would be the least of my problems.

I am referring to modding a new bike like the Honda PCX150. On an old bike or scooter I wouldn't mind going crazy with the turbo.

Turbocharging a scooter won't turn it into a Hayabusa-killer instantly. Don't need to go that far, but still, why just use the turbo to compensate for altitude when you can get a little more boost to improve the low-end torque and make it more suitable to some open-road stretches?

Oh no! I wasn't wanting some sort of sports bike at all. My cars are so underpowered that on any sort of an incline everyone passes me. I just think it would be a bit safer to keep up with traffic on a bike.

At any rate my main goal is fuel mileage. I think sacrificing a few MPGs going with the PCX 150 instead of the 125 is compensated by the slightly extra power. It does have a 10:1 CR. I think most gains would be in aero mods:

Maybe my altitude is a good thing. The air up here is between 4 to 5 PSI lower than the usual 14.7 PSI at sea level. That's kind of like a natural governor that keeps it always at part throttle. Plus there's less air drag as a result.

However, there is a noticeable decrease in acceleration in my cars up here in comparison to sea level driving. I'm sure these bikes aren't the exception.

Scooters are awesome at simplifying your life. So easy to live with and basically 0 maintenance required to run.


You really can't go wrong with the honda pcx. The only comment I hear from owners, is the valve clearance interval checks. 2500 miles. That aside, they appear bulletproof.

Cycle gear sells electric jackets and gloves that keep you warm while riding.
Their body liners work very well as well.

I enjoy reading the battlescooters forum on the adv website.

Hey! The valve check and adjustment on my Beetle is every 3,000 miles! And that's 4 times the valves!

Ya, simplifying sounds good. I got three old cars and never have enough time to fix them up like they should be, let alone mod them for fuel mileage. Yes, I dream a lot of making them all the fuel mileage masters of the universe. But maybe selling two of them for now and getting a scooter would be the sensible thing to do. It's just my wife and I now.

So I guess the first thing to do would be to buy an actual scooter or motorcycle and see if it had enough umph up here. If not, then contemplate boosting the induction.

About how much CFM would a 150cc engine draw? Maybe all I need is the blower off of a Hoover vacuum cleaner attached with a small belt to the engine and then call it a supercharger.
