hey everyone,
i have an intersting and probably impossible project in mind. i can get a eaton super charger off of a mini cooper from a friend of mine for cheap. while doing some research i found that the mini cooper engine spins clockwise and the b16 spins counter clockwise. so, after i find the correct super charger pulley to crank pulley ratio this is what i’m thinking. take the pulley off of the supercharger and mount a gear to the back of it, then place a gear on the super charger where the pulley was. the gear mounted on the pulley rotating counter clockwise will then rotate the gear mounted on the supercharger clockwise. what im wondering is if i can use any size of gears for this as long as they’re ratio is 1:1. even if the gears are twice the size of the pulley or even two times smaller, they should turn the super charger at the same rpm as the pulley would right? as long as they’re ratio is 1:1.? also does anyone know if specialty gears are needed to spin at these high rpm’s? just trying to get a good idea of what im in for before i buy the super charger. thanks in advance.
Is the bolt pattern even the same, or are you thinking of fabbing up a flange as well?
I don’t know one way or the other, but id be completely surprised to hear that they share the same bolt pattern.
Seems like a lot of work and uncertainty due to the pulley situation and the custom flange. I’d rather just go with a homemade/ebay turbo kit and call it a day since there are plenty of kits made to fit the B18/B16 platform.
