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. |
