Supercharging?

[scumdog]

I think you misunderstood me. Indeed ram air does work, I was saying that comparing that tiny fan to ram air is laughable.

Hp to drive fans: 2
Hp gained: 2.5
Hp gain: .5

AND that's if you're lucky!










Just kidding, fans don't take that much hp - and they make sweet f.a. hp too.!!!

I know... but it's something to do during winter. Saw dyno charts giving 1-2 or 4nm and NO hp on a 280hp porche or something like that, slightly better low down that's it. It's something but not much. Might as well go FI.

Those fans will do 100-150cfm if you get dual motor ones (rare and limited runs etc) but it's the pressure that counts not airflow.

Hmm you meaning electric? Run them switched on the battery and it won't use much more than a decent late model HID system, turn them on when you need it. Wouldn't use HP to charge battery a little bit more than usual really...

I defy anybody to make a MEANINGFUL hp increase using electric fans.

Ok, so you've figured out how to get 25% more power from nowhere? Time to quit your day job, you're too smart for the police!

I feel meaning saying you're an idiot, but hey I'm not that sensitive. You're an idiot.

No you get a .5 hp for a total output of 2.5 by the time parasitic loss has ben subtracted - regardless of capacity.

I'd be pissed off if my 7 litre V8 only put out a .5 hp increase for a few hours work and an extra 2kg of wiring, fans, motors etc..

Excellent, I thought you'd lost it Love the Dyno graph on that page... made no difference... the differences in curves could be the differences from two different runs

But in all seriousness, I've got some magic beans you guys can buy... grow a money tree, honest!!!

Has ANYBODY ever heard of REAL boost from electric fans???????

Except on a hot day after cutting the lawns????

[imdying]

Only those that are on P.

Here is a link to some info on electric superchargers

seems to be a waste of time, but there will always be a queue of hopefull christians.

Everyone knows the quick route to more power is trade up to a 2 stroke!

If I wasn't going to bling you for the link, I'm sure blinging you for the 2 stroke comment! Go the strokers

im sure there must be a decent electronic supercharger out there not these pathetic fans... i dont want to turbo the spada, but i do want around 60rwhp and more torque....at the least... NOS???? nope. not constant enough and also has to be refliiled

I thought the bottom end on those Honda 250cc V twins was considered not to be strong? Reputation for big ends going? Need to consider that .

[scumdog]

In the 'old days' (the 70's) there use to be a 'priority valve' that let you run naturally aspirated until your turbo had enoug boost to close the valve and start directing boost into the engine.

Can't have worked too well (a bit like the fan thing - and I was being over generous when showing how much of a paucity of power it produced) or they would be still around.
K.I.S.S. - Keep It Simple Stupid in whatever hp increas method you choose.

Good luck!
