Ya, I was looking into electric. Couple of issues I thought of are amp requirements and not having variable boost for variable throttle positions. Be interesting to see how much boost a high rpm rc edf fan could produce, they come in all sizes, so it wouldn’t be hard to mount one inline on the air box intake. I think someone might have done something like that on a 700 with a bigger 4 or 5 inch electric blower. One could even rig up a second battery in series to get 24v. My guess is that the most boost any electric system will produce is 2-3 pounds. But it would prob give a noticeable power increase.Cletus McFarland played around with electric turbos..the cheap china toy ones are a joke on a car, the larger $$ ones made serious power but with this little engine the tiny one could be a fun experiment, who knows...
for the hassle and the headache of that 100% not worth time or effort. you need to find the max cfm of the motor draw then then a bunch of math i dont remember off the top of my head to figure out what size blower for the cfm you need to create any amount of boost

Pretty much the same conclusion I had. And I am a better welder/fabber then electrician. If I can get oil supply figured out, I prob will try a rhb31 turbo. Not a lot of dollars wasted if it doesn’t work out. Would have more in the dobeck tuner then the turbo setup. And it sounds like I need a tuner anyway. Turbo location is pretty simple to plan out. I don’t think I would intercool it since 7-8 pounds of boost would prob be the highest I would run. Not sure about the air box though. Thinking to just run boost hose to the stock air box intake, but the crankcase breather would need to be changed.
exactly what i was thinking when i started planning it out but then i got into building my long travel kits and kinda put this on the back burner

I'd think if you did this it would be very necessary to put the taller gears in, heavy duty clutch (if they even exist), and raise the rev limit within reason. I love the thought of a quick 500. It would be quite a challenge though. Re-powering the machine might be easier.

I'm enjoying this revived thread. I went through all these mental thoughts last year, all starting with tapping into the oil cap and checking/testing oil pressure. Looked at turbo's even glanced at the "tiny" Garrett GT0632, but never did anything with it and when I needed more power now for the tracks and saw the BBK & cam kits available I had that thought: "This is easier AND proven". Now I'm really glad I did it but if one of you builds a turbo kit that would be sweet!!!

i would still love to do the bbk and cam!!!! i take it ur loving it so far

I am loving it. I just wish for 2-3 hours it was warm and the snow was gone just so I could do an apples-apples comparison with my tires back on. With the tracks, even with the high gears 32mph + or - is max. Can definitely tell there's more there, it just doesn't bog as easy but that's really my only comparison right now. Definitely louder overall naturally. To be honest most of my limited riding thus far is 6-8 mph gps in 2nd going through woods in 20-24" powder on old logging roads, with the wife and both labs in the back.
It does run a little warmer. I installed a digital temp gauge spliced in on the upper radiator hoses. Going down the road she stays at 185-195. Service manual says thermostat starts to open 178-184 and fully open at 203, or something. Anyway, I know it's working a little harder in the snow, but the fan does come on often, which happens around 210-213. Brings it down to low 200's then slowly climbs back up. But still never past 2 bars on the dash "gauge"!! But then again my Yamaha Big Bear only time I hear the fan is plowing, never in summer.

well geared down with the tracks im sure the Rs are running pretty high most of the time
right man a just a 10 hp shot would feel ridiculous in the p5 lol thats a 50% increase lmfaoNitrous is waaaaaaay more fun duuuuude

Engine swap would be cool, but space is pretty limited. And I would hate to give up that 5 speed manual tranny. The 560 big bore kit would probably be more reliable than a turbo and a lot less work, but my conscience wouldn't let me pay $950 for a cylinder and piston. And I just rebuilt the top end with a wiseco, so it has lots of life yet. Not too worried about the clutch, if it is overbuilt like most of honda stuff is, it should handle another 10hp. Already have the taller gears in, they are probably the reason I need that extra 10 hp.

I would love to know more about the BBK & cam kit. How much did that improve performance and what was the cost and assembly like. I have tracks and need more power. Thank you!
Nitrous is not intended for long term use, just a quick boost at the expense of high engine temp and valve abuse. The lower the rpm when the nitrous is injected the worse, need high rpm to get the hot gasses out of the combustion chamber quickly. If the goal is to make a less reliable machine I would just go get a Polaris! I don't know much about turbos, other than it's a good way to burn through gas quicker ... Dang I am getting old, speed use to be my main goal, now it has been replaced with reliability. ☹️
