odd forced induction question

Hey i'm new to rotary engines and had an odd question. i'm in the process of deleting the rats nest and it is going well, however i know i am supposed to remove the air pump but i was curios as to whether i could be able to use it as sort of a makeshift super charger. i'm not sure if anyone has tried it but it seems like it could work. basicaly my questions are:
1.) is it possible for this to work?
2.) with stock internals will this greatly harm my seals and other internals of my rotary?
3.) i have some ideas of where i would run it into my intake however does anyone have any other suggestions as to an appropriate spot to run the air to?

No. Not nearly even close to enough flow. Unless you are talking about a 3.5HP lawnmower engine and gear the air pump to run around 10,000 RPM.

It also disengages at ~ 3800 rpm. If you defeat that, it wouldn't last long.

So you're deleting the rat's nest? Do you have a standalone ECU?

I am curious as to why you think that you need to remove the air pump, or even the rats nest for that matter.

Ah, and that is also a good point which I missed. Unless you have a very specific reason to remove the emissions system and a good understanding about how it is done, I'd suggest leaving it all alone. 99% of cars with an emissions removal never run correctly again.

Unless they have a well tuned standalone, that is.

i was told it was a good idea to do it. especially since when it is cold it dies until it is warmed up. new to rotaries and everyone i've seen said removing it was a good idea and would alson help with the start stall problem by allowing the engine to regulatefuel on it's own whitout emmisions restrictions.

You gotta listen to guys that actually know what they are dealing rather than someone who,for example,sells Ice Cream..
Emissions removal is not a way to get the car to run "better".
If it was Mazda would have done it right off the bat and saved you the hassle of doing it.
Air Pump super charger?..sorry not gonna do it.
It can't supply enough air to make any Real HP..(though the idea is not totally "crazy"..so I'm not calling ya Bonkers for thinking it!)

ya the air pump question was juston off chance idea i was far from confident that it would work. and ya emmissions i generally do not remove except when doing a very performance tuned build where the equipment actually interferes with the engine's performance. i had just seen so many thing about it and heard from so many people i thought it may possibly have been purely a rotary engine thing where mazda had a poorly designed system. thank you guys for the advice saves me a lot of time and effort except now it's time to diagnose the other issues ha

Unless in poor condition most emissions equipment has no effect on performance in general. Most people that do remove it do so for cosmetic reasons.
