adjustable inlet turbo

[Clip]

woke up this morning and a thought popped into my head. tell me why it won't work.

would there be any plusses to designing a turbo with a spiral shuttered inlet that will open and close with the speed of the engine?

a smaller inlet would allow less air while a bigger inlet = more air. this wouldn't have any effect on spool up time though, because that's dependent upon the hot side, right? never owning a turbo, im not sure if this is right or not.

im trying to find pics but can't think of a name to search for.

That would wreck havoc on tuning would it not?

that wouldnt do anything good.

Keep your day job...:evil2: :nono:

Alright, thats it. Lagged, I'm sending you a quarter so you can go get some air in that tire. :icon_bigg Its killing me. Thanks.

Sorry for the offtopic.

I could swear Acura tried to do something like this on one of it's turbos or something similar.

i asked why it wouldnt work, make it constructive criticism.

sorta like vnt on diesels and porsche tried.. not worth the hassle..

Is there a benefit to decreasing air flow on the main intake?
usually, for dyno runs, the air cleaner is off, which makes me think more air at that inlet is all good. What is the potential benifit of closing that any? just wondering.

What possible potential benefit could creating a restriction or vaccuum on the inlet side make?

It's not a question of it "not working" it's a question of "it doesn't make any fucking sense to start with"...

if thats the case then why dont all aftermarket turbos have a monster of a compresser housing there has to be some benafit to a smaller size.

 

[buckshotglass]

Clip only asked about the inlet in his first post.

 

[TurboWarrior]

Maybe a benefit to a smaller wheel/housing not the inlet

so should i be thinking about the outlet side, or are turbos designed to flow as much air as possible? if i owned one, it would be easier to conceptualize; i dont fully understand why porsche designed a turbo that would adjust in one way or another to be more efficient.

i think you are misunderstanding a few concepts of basic turbo charger operation.

try the howstuffworks website or wikipedea and read up on how turbo's actually work.

or if you are near a bookstore, pick up maximum boost by corky bell.

thats about it. ive been looking for maximum boost for a while, cant find it anywhere around here. gettin ready to order it online

its a good thing im NA, or id have already killed myself :biglaugh:

Look up the "whoosh mobile" or Andy Granatelli. Also look up Turbine Powered Indy Car.

USAC regulated the air inlet size thus reducing horse power that the turbine could make. The down side to that was: Reduced power and HUGE INLET AIR TEMP SPIKES.

Just letting you know.

I think what Clip is trying to say is to have a variable inlet side to the turbine housing. Maybe thinking that (a smaller opening) would increase the exhaust gas velocity hitting the turbine wheel, thus creating faster spool-up at low RPM's. And then the inlet would open up at high rpms's to reduce back pressure. Sort of like an adjustable A/R.
