New billet underdrive water pump pulley

[b00stedtalon2]

Testing this out for a friend who plans to put these in production for DSM folks. They'll be offered in two versions, one that deletes the power steering pulley and one that allows you to keep it. TI hardware included

The main purpose of is this to slow down the water pump which is beneficial at high RPM. I'll be comparing water pressure and temperature between the underdrive pulley and stock this weekend.

I'd be interested if it was not underdrive. Will he make a stock size option?

He will only be making underdrive ones.

The underdrive pulleys he's made for the Evo 7/8/9/X have shown to drop coolant pressure, better cooling time for the fluid in the radiator, and reduces cavitation to the pump from forcing coolant when being over spun.

More importantly, what is the underdrive ratio? And a stock option will be a good selling point

I'm in for one, maybe 2.

Nice! I'd probably be interested in one that deletes the power steering pulley.

Did these ever get made for purchase? Any feedback on how they performed?

I’m running this on my 2gb 7bolt rn. What size belt are you running for it?

Any update? Where to purchase? etc.

The guy made a batch a while back ago. I have one and it's great. I think the seller is Daniel Mergenthaler of EvoSpec Performance.
