has anyone ever heard of someone putting a computer fan on the intake and getting a massive power increase because it acts as a "turbo"?

ROTFLMFAO

If you actually believe that then I have a 3 speed adjustable hair dry... I mean turbo to sell you.

I THINK YOU SHOULD TRY THAT! lmfao, AND YOU CAN GET THE POWER FOR THE VACUM FROM AN ELECTRIC BIKE.

umm even if you tried to put something together, you'll have to rejet the carb and do alot more work... its not as easy as you think. even a different air filter will make a difference on how she runs. take my elite for example, she wont run with out the air filter on and if she does all it does is sit there and bog out. so that'll be the same thing as turbo

My reaction was not unfounded as this actually came up in a conversation with someone else recently and I thought the irony was just perfect.

A turbo typically spins at 100-150,000 rpm by having a turbine in the exhaust which spins an air pump. So to replace this without hacking your exhaust you would need a motor that spins about that fast to push air into the carb.

Since air pressure at sea level (which we all learned in skool) is 14.7 PSI then you would obviously want to increase this and ensure that you get around 20 PSI for a boost of about 50%.

Now assuming I did my math right (and I admit I could be very very wrong) you would need a fan running at 1146 CF/M pushing air into a 5cm round inlet with a 4.5cm round outlet at 25 degrees celcius at sea level.

That's assuming everything is at a standard ambient temperature and pressure of 25 degrees celcius and 100 kPa and your tube having no loss, restrictions or turbulence (which is impossible).

So there you have it, math strikes again! Who'd a thunk you might have needed it after all those years out of skool.

I actually have a very small turbo that I'm going to try and make work on one of my bikes. It'll be a good project for me this winter, along with putting a clutch, and another turbo in my Eclipse as well :/
