Minarelli Performance Cooling Fan?

What makes this a Performance Engine Fan ?

Re: Minarelli Performance Cooling Fan?

I bet somebody stuck it on a lathe and machined the fins down some for reduced drag.

Re: Minarelli Performance Cooling Fan?

Constructed of substantially lighter materials? Ionno...

Re: Minarelli Performance Cooling Fan?

they sold them on a site in europe i was looking at im guessing they are lighter but the fins are untouched

Looks normal to me.

Re: Minarelli Performance Cooling Fan?

inside could be different

Re: Minarelli Performance Cooling Fan?

Look closer... the fins stick out of the circle... hmm.. file the places in between the fins? Look closer.

good eye Ed

Re: Minarelli Performance Cooling Fan?

The price!

Re: Minarelli Performance Cooling Fan?

it aint going to be any different

it should have curved blades then it will have less drag and spin faster

Re: Minarelli Performance Cooling Fan?

i emailed the seller and they said it would have 20% less drag.

Re: Minarelli Performance Cooling Fan?

bullshit

Re: Minarelli Performance Cooling Fan?

If it really works, that's cool.

I'd like to have a spare fan for my V1 so I could try to make something similar.

Damn placebo parts. I tried modding a V1 fan for less drag, it didn't help/hinder the motor. Heck the best thing you can do for a slow V1 is port the sucker!

Re: Minarelli Performance Cooling Fan?

let's say for argument sake that it did reduce drag by 20%. would it even make a noticeable difference?

Re: Minarelli Performance Cooling Fan?

75cc Polini works sweet too.

I can't get enough of that Pacer-looking bike, excellent colour-coordination hot hot hot!

Re: Minarelli Performance Cooling Fan?

Wouldn't a performance fan increase, not decrease, airflow for better cooling, increasing performance? I don't think the spinning fan is holding you back.

Re: Minarelli Performance Cooling Fan?

the fan slows the engine down it revs a lot higher without the fan

we need someone with a machine shop make a billet fan with curved blades

and if its made out of magnesium it would be lighter than the plastic one

Re: Minarelli Performance Cooling Fan?

somebody could do a resin cast also using silicone as the mold to make a lighter fan.

Shaddap Jon. :-P You just wait till I get that Carabela running!!

Re: Minarelli Performance Cooling Fan?

Jon that is HOT!

Re: Minarelli Performance Cooling Fan?

Bret, that fan is certainly hold the engine back.

When I installed a new front sprocket a while ago, I rode it for a couple minutes without the fan... MAJOR difference.

You'd be amazed just how much drag that fan creates.

Without it, the bike was crazy responsive and fast.

Too bad I can't ride all the time without it...

Re: Minarelli Performance Cooling Fan?

Im going to ask cause Im not sure but, is the fan really needed other than at very low rpm and at a stop?

The reason I ask is, isnt the cooling fins being exposed to enough air at speed that the fan isnt needed.

On a automobile the fans do nothing to help keep a radiators temperature down over 35mph, the air that is passing through the fins is more than sufficent, thats why they make fan clutches for car/trucks.

I know there is a lot of two-stroke engines that dont have any fans at all, has anyone ever tried to run without the fan(not at an Idle/standstill) for a period of time to see what happens.

Re: Minarelli Performance Cooling Fan?

i think that question has been brought up before, but i dont remember what the answer is.

i do know that the fins run a different direction than most cylinders - horizontal rather than vertical i guess you could say? they run side to side to catch air blowing from the fan rather than front to back to catch air moving past the moving bike.

so it wouldnt be exactly the same to just run it without the fan and let the movement of the bike do the work..

Re: Minarelli Performance Cooling Fan?

Plus, then you'd probably have to remove the fan/flywheel cover to let air flow over the cylinder fins. That would leave the flywheel exposed to dirt, water, etc. Plus it would look ugly. I suppose you could modify the cover, but then your cover is ruined if you ever want to put the fan back on.
