Cheap c230k smaller supercharger pully?
Hi everyone,
Ive seen a smaller supercharger pulley on ebay (see link)
the 30+bhp claim seems pretty ridiculous, but if it could squeeze 5 or 10bhp for the money it seems like an awesome mod. I mean the physics/principle seems sound
any thought?

Many Thanks

That small pulley is a ricer upgrade.
If you have an American M271 C230K, then any pulley change is likely a ricer upgrade.
Basically, the American M271 has the smallest pulley and greatest boost possible for the M271, unless the boost sensor is changed, a significant tune is done, and inter-cooler mods/upgrades are done.
Even then, the power gain gets murky for a street-driven car.
Fwiw, I bought a new supercharger and had it professionally ported by Stiegemeier ( http://stiegemeier.com/contact-us/ ).
I also have spent a significant amount of money on replacement/etc components - including a Kleemann header and cat, 100% new head and lifters, tune, etc.
I did not put the ricer smaller pulley on my supercharger.
Fwiw, you should/must run a dual-catch can system because of oil caking on the intake valves. This is a Very Common problem with an OEM supercharger or turbocharger setup.
Do not go with a cheap catch can system. Imho, a good one often costs ~$100+/each.
Fwiw, the ones that I went with cost ~$250 each.

Price: $243.75
Imho, don't ask about mods unless you fully read and understand all that is said in the threads listed below:
Imho, this is not a Camaro or Mustang forum, where many/most of the members are experienced gear-heads who have done and are knowledgeable about the mods for a very specific engine / car-platform.
Good reads for mods/upgrades for an M271 engine:

Hi Red,
Thank you for you in depth response!
I've had a quick flick through and it certainly seems a lot more involved than a bolt on fit and forget mod (and expensive!) very little bang for your buck.
I know a fair bit about modding turbo cars, mainly Japanese but for what its worth on my old Merc for the cash its not feasible.
my car is the uk/euro version and i very much enjoy driving it as is.
I planned to do the pulley and get a remap + air filter, but as the links you posted suggest its not worth it.
Many Thanks

If you don't have the American ~192HP 1.8L M271 engine, then putting on an "American supercharger pulley" may give you a power boost.
However, replacing the pulley is not a DIY procedure. Imho, replacing the complete front snout (from a SC that has a smaller pulley) might be a better choice.
Getting a full custom tune for an M271 won't be easy (I'm not sure it's still even possible).
Fwiw, I went with the OE Tuning option:

Good Luck!
