Thread: GregV Crank Pulley Installed

If thats a VE......your a disgrace.....lol jk

LMAO. I'll clean it this week. Thats the only side its dirty like that.


lol. No VE, it's a DE.

Awesomw I will install mines tonight. I've had mines for about 2months and never had it installed. I'm going to dyno again after the install to see what's the difference.

Does both the VE and DE block need shaving to fit the WP pulley?

we have to shave the block to put the WP pulley on a VE??

btw is the gregv pulley weight the same as the VE pully and how much power can be gained w/both pulleys??

I have never installed one on a VE so i do not know the answer to that. The WP's are different so maybe those were designed for the VE and it fits ok.
Anyone with a VE ever install one?
As far as HP i am sure it is close to the UR pulleys but the WP is bigger so the engine runs cooler, my fans never kicked in even when reving out, or stop and go traffic.

Greg, correct me if I'm wrong, but if wp puley is "larger" it slows the water pump speed further, thus saving some parasitic power loss but is not off- setting the slowing of the crank pulley ?

the smaller the diameter the faster it can make 1 single rotation..the larger the diameter the longer it takes ot make 1 single rotation.

I agree with the statement and i wondered the same thing when i was installing it. So why am i running cooler than i was with the stock pulleys. I installed both crank and WP at the same time. But i also installed a Nismo Thermostat, but i would not think that would cause a huge difference.

I under stand "under drive" pulleys reduce the drag on the motor but wouldn't you want the WP to cool at or even above the factory for enhanced cooling? Since most people who use them are running the car harder than the average driver you would want more cooling.

I guess i never fully understood the idea behind this. I could care less about the Alt, or other acc's spinning slower but i think the WP should spin faster.

cavitation buddy. the pump spins so fast that it gets to a point where it cant even pull water forward as its "scooping" way to fast a air pocket is almost created. No coolant flow means overheating

so for higher rpms you want the pump to move slower so it still moves the coolant
