does anyone know of a really small turbo??

[turnipheed]

planning on supercharging a minimotolol but i need a small turbo for the job can anyone think where they have seen one bolted too??:thumb:

[Bubba]

supercharging or turbocharging?

[Pistol Pete]

lol space is at a premium in a Nova. A mini moto....what you smoking!!??

[turnipheed]

lol yes supercharging using the cold side of a turbo and driving it from the sprocket should be a laugh if nowt else!! no smokin nowt that could be the problem!!

[craig green]

Fiat are about to launch a 2 cylinder petrol turbo engine in the 500. Maybe wait a few years & use that!

[Stuart]

you will need to gear it appropriately to make it do anything, otherwise its going to be laggy and peaky.

I guess find whats used on something like a hyabusa (unless they put hoooooj ones on those)

Hmmmm, interesting but its electric lol surely it will do naff all?

too costly really just a shoe string effort
yes it will have to be geared right probably be trial and error the 49cc revs to around 12-13k and a turbo at full boost is 100k ish i believe so i really dont want it boosting at that !! s probably between 2:1 or 3:1 to begin with and take it from there im expecting a blaze of glory then a catastropic engine failure lol

[Stuart]

You will be wanting nearer 10:1 on the gearing ;)

[turnipheed]

yeah i seen them more wanting mechanical version cheers tho ;)

[turnipheed]

You will be wanting nearer 10:1 on the gearing ;)

surely that would take the turbo to about 200k? in that case i would be better putting the pipe out the back and get blown along lol

[Stuart]

your maths bites.... worst case 10*13K = 130K ;)

[nova_saloon]

lol electric turbo. might aswel get a leaf blower and do it.

[turnipheed]

your maths bites.... worst case 10*13K = 130K ;)

sorry :tard: even still at 130k could be a bit much for the little engine to swallow thats what i meant by 2-3:1 =26k-39k if my maths doesnt fail me again

[General Baxter]

were having this problem on the local chav forum

he wants to turbo his 1.6 astra, by bolting a turbo to a motor lol

[craig green]

Is this mini-moto 4 stroke? Can you turbocharge a 2 stroke??

[burgo]

sorry :tard: even still at 130k could be a bit much for the little engine to swallow thats what i meant by 2-3:1 =26k-39k if my maths doesnt fail me againyou fail at understanding turbos

[Pistol Pete]

To my knowledge pit bikes are 4 stroke, minis are 2. Cant see it working IMO. Well it might for a second then....BANG!!

just want to help it get up the range, not just gona bolt a turbo on it and scratch my head when it doesnt work or eventually/ inevitably blows up

[turnipheed]

yeh thats probably it no harm in trying a bit of low boost for a gigglelol

why?

T25 is 'normal' on a busa..

[turnipheed]

very good point not a hundred pc sure if you can turbo a 2 stroke not had much to do with 2 strokes really, but i presume so because you used to get 2 stroke diesle hgv,s and i would hazard a guess at them being turboed

[turnipheed]

T25 is 'normal' on a busa..


1300cc and 4 pots and a few hundred horses though im talking 49cc and maybe 4 raging horses lol

[craig green]

You'd need to seal the carb & all that malarkey aswell, otherwise the poitive pressure you've created just leaks out through the carb.

[turnipheed]

:confused:

aye defo thats a hurdle to cross dont know how a chainsaw carb will react to shoving air through it but same again trial and error

[burgo]

why?because its an impeller which are designed to work at a specific range of rpm. in other words unless you spin it fast enough it will do sweet FA, what exactly do you think lag is?? lag is waiting for the turbo to get up to speed to produce positive pressure.


you need to get a small turbo and gear it so it works at its optimum range and then limit the boost somehow. also if you have the carb set in a suck through set up you dont need to mess around sealing it

[Count Vaux Alot]

i understand lag perfectly but tbh most turbos that i will be canibalising to make a charger with will be designed to run much larger engine and i was going on the theory that although the turbo at full boost can produce x amount of psi at peak range i realisticly only want 1 or 2 psi hence gearing it to run at what ever suits the tiny engine best, how ever i am interested in seting the carb to a suck through set up can you explain?

[turnipheed]

lol at this thread


at least u get the point lol

[burgo]

you miss understand. james finds it funny because he builds turbos for a living and loves the tardness. try here www.google.co.uk

[Sloth]

err o.p google draw through systems, no need to seal yer carb. and the smallest one i remember seeing was a corsa diesel one its a gt15 or gt12 iirc.

TD turbos are IHI so don't follow a garrett naming structure.

[Stuart]

The 'turbo' on the 1.3cdti is rather "cute" lol..... I think its more of a restriction than a gain lol.

You can boost a 2stroke, but generally its supercharged and not turbo'd (using a Positive displacement style charger). When you S/C a 2 stroke well you can actually run the engine as a wet sump and use rings to get even more power/life :)

tbh thats probably the best route to take...


I'm now considering nitrous for the vx as it only ever 'needs' 200+bhp in the straights so would be ideal to nitrous

cheapest gain in my opinion stu and for this guy a £20 nitrous kit is better than faffing about trying to get a turbo to work :cool:

[Angus Closier]

Yes this may be true, but clearly its not what he wants to do otherwise he would have asked for nitrous kits....

If your wanting to lash up a supercharger with a small turbo use a t25 and just gear that right. They are cheap as anything so you dont have to worry messing it up. I doubt it will be very hard to do tbh. Doubt you will ever get it to run right but if its just a small amount of boost you want then its possible.

very true but check the vid the things cant even handle nitrous mind a turbo

[Angus Closier]

Yes but he could gear it so its just like a person blowing into the carb???

You dont have to do the extreams you know when supercharging/turbocharging/nitrous??

A smaller ammount of nitrous would be good for that bike.

A hayabusa is 1300cc, and a minimoto is 49cc.

Also, as a minimoto is a 2 stroke it will be cack.

Better off getting a decent engine built:thumb:

omfg is there no end of **** you speak?
2 stroke engines are amongst the most powerful available, turboing and supercharging them works extremely well. you need to read some more stuff...

as for the turbo from a busa not being useful, turbos are not related to engine cc, they are related to the compressor map and their flow rate. so it actually coukld be spot on.

so tell me what engine would you build?

what a contraption

[Lewis.]

One thing which everyone has overlooked, is that 2 strokes have a crankcase valve, any almost all minimotos use a reed valve. A read valve is totally unsuitable for use with forced induction, as the boost will just blow the reeds open permanently, and you will never compress the mixture in the crankcase.
To turbo/supercharge a 2 stroke, you need to use a disc valve, or choose a motor with a skirt controlled valve

will be an epic fail i'm afraid

good point, its going to take a bit of research this,as i say its just for a giggle not taking it to serious good to have all the opinions though :thumb:

supercharging is the way i was planing i think i have just confused everyone by asking for a turbo but its only the cold side im needing as i plan to drive it from the crank rather than being gas driven , should be a giggle if nowt else or a trip to A and E lol

[Stuart]

Rotrex style ;)

[svlet]

nos is also very fun i used to have one of them little kits some one put an ebay link to linked up when i used it i used to have to hang over the front end or it would flip. dosent last long on one of the little cans tho .

exactly stuart but a little more bodgedlol

[nova_niek]

Nothing to do with strokers, but this (http://www.elsberg-tuning.dk/the%20bikes.html) is worth a look since it's 49cc territory.

And here's (http://www.elsberg-tuning.dk/supercharging.html) some more info on forced induction.

excellent link cheers:thumb:

[Stoo]

Ive got a turbo'd mini moto

You can buy it if you want :)

[mowgli]

i bet there is a bloke who still lives with his mum who has built a model supercharger in his shed..

there are loads of youtube links to people who have turboed a lawnmower etc.

but in terms of £ per hp, its about as bad as tuning a 1.2

[Sloth]

the cub motor does fit, and is a riot.

i just rememberd you can buy a 125cc supercharged scooter why not try fit the super charger off of one of them ?

Took a turbo off a pug van today it was tiny, apparently same engine as a tranny imo it could be hooked up to a mini moto lol

Peugeot Jetforce?? Its a 4stroke.

on another note i walked past a broken down buss the other day and the turbo would have sucked a mini moto in it was huge completly irelivant i know but hay>
