"TURBULATOR" for 1st Gen. Carbs

Anybody ever use a "Turbulator" --do they actually work or are they "snake oil" ? See: http://street.parts-unlimited.com/10...0?q=turbulator

TURBULATOR
Features

* Turbulators use a fixed-vane vortex design that turns your intakes into violent mixing chambers
* These vanes eliminate heavy droplets of fuel, fuel stacking and keep fuel from puddling
* The result is no more load or dive spots; just crisp, clean throttle response throughout the powerband
* Complete atomization also increases fuel mileage and eliminates standoff

Would you honestly buy anything called a 'turbulator' ?

I thought the general idea was to get rid of rough casting marks and smooth out the inlet tracts to reduce turbulence to get the maximum flow into the combustion chamber.
But I do remember that on the BSA Gold Star 500 you were supposed to leave the step between carburettor and head or you would loose out on power due to loss of turbulence, just might be an old urban myth though.
If it was any good the bike manufactures would already using it.

from what ive been told, near the valve openings its stepped, you want to leave thoes there as they make turbulance as air it enters the cylinder, all the way up the carb i think its ok smooth it out.

now im not 100% sure, its just what ive picked up.

Some older Suzuki four-valves, fitted with Mikuni carbs, had a gauze/mesh type thing fitted into the carb mouth, apparently the same effect was intended. I note they're on a page titled Mikuni parts, tools etc - are these actual Mikuni parts? If they are I'd be less sceptical, Mikuni know what they're doing so these bits may well have a purpose, although that page isn't written by Mikuni so it might not be what's being claimed there.

Fecking brilliant. Now ive spat squash at my laptop


On the other note


AAAAAAAAAAHHHHHH HAHAHAHAHAHAHAHAHA

Its bobbins.

The theory is sound but this is done in the inlet tract and cylinderhead. A better "swirl" improves torque. However that thing will do bugger all for your bike. prove it does and ill happily show my ass in the town centre!

Although dont be ashamed of asking. Some people will ahve bought it! laugh at them instead

Nope it's boswallox. You get plenty swirl around the valves and in combustion chamber. You can get a couple of bhp with mild porting, never mind restricting the inlets.

I am getting the impression you bloaks don't like this thing.
