Oil pump upgrade
« on: September 18, 2013, 09:19:43 PM »
Hello there guys. :)

My Fuel injection project is doing great and the next project is to add the VZ21 RHB31 turbocharger to see if i can make any boost, but i think i will need an upgrade of what the oil pump is able to pump since it will then suck the oil through both the oil cooler and the turbo.

The problem is that the only high flow oil pump i've been able to find is the round type for the 125cc engines, while ours is of the triangular type. Do anyone know of a high flow oil pump of the triangular type or any mod that i can do to the engine to give it higher oil flow? :)

   I looked around too and didnt find much. It appears there were two different tooth counts on the oil pump drive gear on the crankshaft depending on the engine, and a different corresponding pump drive gear. I also seen this aftermarket metal drive gear for the pump. http://www.sip-scootershop.com/EN/Products/GY600075/Drive+Gear+Cog+GY6+oil+pump+.aspx?_country=E993AB67-6807-4109-BBED-F6374EBF9F9B&gpc_origin=pla&gpc_feed_alias=us&gclid=CKTM9tTG17kCFcvm7AodriIA9Q

Might be worth calling these guys.

Wasn't what i was looking for, but still great! :D
The plastic gear could be a weak point when tuning and raising rpm, so it should definitely be changed to the metal one. Thanks for the link! ;)
