An Idea I Came Up With

[rice_me_up]

ALRIGHTY THEN!!!

last night was pondering and i came up with this idea. i dont think anyone has the recources to experiment this idea but I want to know ppls opinions etc.

ok. here goes:

On the turbo shaft have something that works like a freewheel on a bike (can spin one way but not the other). attatched to the "freewheel" would be a belt to a pulley that spins at a constant rpm. the idea being that the compressor wheel would be spinning at a minimum of X amount of rpms and could not spin any slower than that. on another part of the shaft have a system that makes the exhaust wheel spin seperately from the compressor wheel, but when it hits "x"amount of rpms, it engages the other half of the shaft so the compressor wheel can spin faster and create more boost.

if you dont get a part of it then i shall elaborate on it.

cheers. james.

NO FLAMMING PLEASE!!!

how are you going to control the boost level ?

[Mr. Oizo]

You might as well just use a supercharger...

[rice_me_up]

DARK: true. a twin charge system would probably be better.

silent: i spose a waste gate would still work?

Too complex, too big, too much gearing required to spool the turbo at idle. 1000rpm vs 80,000+ rpm.

They already have a similiar 'concept', its called electrically assisted turbo. Basically a little elec motor spins up the turbo.

[WogsRus]

or simply incet a bit of fuel into the port on the exhaust stroke, work for WRC and my mates scuby.

a good idea, but a littel bit to complex, Well done

anti-lag... problem solved

once i get mine back from japan, i will post how well it works

[Guilt-Toy]

It wouldnt work. How would you get a belt to deal with temps as high as a turbo gets? it would melt as soon as the turbo heats up.

[Cubes]

A chain.

Now its getting ugly..

Or even better, how about a solid drive gear.. sound like a supercharger then. lol

[Guilt-Toy]

Then your going to have to run the turbo right up near the head light to give it direct access to the pullys and you will have to get rid of your air con and you will have too.. ummm....

Yeah... I would look at installing a supercharger to reduce lag or get a anti lag system.

This idea wont work - only the electic motor thing works

A chain.

Now its getting ugly..

Or even better, how about a solid drive gear.. sound like a supercharger then. lol

[MKDR33]

or just get a custom titanium belt/chain made up to drive the freewheel.. the idea is too complicated though..

as said before/above, just install a supercharger..

[Guilt-Toy]

but what happens when the turbo gets to 100,000 rpm ?

your gona have to have a clutch on it too.

[700HP-GTR33]

A chain.

Now its getting ugly..

Or even better, how about a solid drive gear.. sound like a supercharger then. lol

A small fan, electric fitted before the AFM will work it could be installed neatly after the pods.

The D-getro (APEXI POWER F/C)system gets rid of the AFM, is this what gives us lag?

They claim, the turbo's have almost instant response after tuning.

Great Topic. :sorcerer: :sorcerer: :sorcerer:

[rice_me_up]

thanks for everyones' ideas and input.

but please, keep going, im enjoying this.

also, i agree. it does seem to be a too complex system.

question: i hear that the anti lag systems severely reduce the life of the turbo. although its only hear-say (to my knowledge), it does make sense that it would reduce turbo life.

cheers. james.

ps: does every one like my wicked ms paint skills?

[StockyMcStock]

when you can design a plate (or any other type of) clutch system that can engage and operate smoothly at 70,000rpm, let me know. until then it's useless.

[Ska]

Why not hit the exhaust wheel with compressed air when the throttle opens? Have a nozzel to point it in the direction of travel, hey presto it spins?

How much compressed air would you need but, and how much power would be taken away from the engine to run a compressor, and how much space with a munga big mofo tank take up in your boot?

[SECURITY]

wont the belt or chain put the shaft out of balance?

[VB-]

yes i'd have to say twin charger would be better/easier/cheaper/actually work than this, but it was a good idea, i've always got these things goin through my head, and i love reading about other peoples. good work!

i think we should start a thread for this, everyones ideas of possibilities, although most will be unrealistic... would still be an interesting read, providing no-ones thinkin of stealing ideas/suing etc

[Cubes]

I think were all starting to take the piss now... lmao.

[benl1981]

Just imagine a chain coming off at 70,000rpm.

The bearings in the turbo would have to be bigger to take the extra load etc.

nice try..
