MX-3_4evr's N/A build part 2!

[Mazda_Powered]

Measured the alum pulleys and got --

Crank Pulley - 108 mm = about 4 1/4 in.
Alt. Pulley - 57mm = about 2 1/4 in.

w/p pulley (to be made) 132mm = about 5 3/16 in.
.

If you can get the factory size for the pulleys that would make it easier lol

i dont think were gonna need to worry about the pulley sizes. if ya think about it.....its really not gonna be a huge deal.
--kinda forgot to get the dimensions, after the alum pulleys.... had some big 'distractions'

Hey guys, have you seen these camshafts on eBay?

That's nice that someone is making regrinds, but from the HP gains, I rather do the exintake cam mod for more HP

[MD323]

Cams are very very reliant on your other mods, so advertised HP is nothing more than a billy mase oxyclean infomercial

[mx-3_4evr]

True that! If I were to buy cams, it would be for a BP-4W head.

Modeled up pulleys



here are the models of the pulleys. i am very satisfied for the w/p pulley! gonna look wayyyy bad ass!!!

let me know some input. thought of a different design for the w/p pulley also....but this flows with the alt. pulley so i figured id go w/ this one...

[mx-3_4evr]

That's wicked! I like it!

[mx-3_4evr]

The W/P pulley looks weird. On your model, the pulley sticks out, unlike the original goes in. I'm talking about the center. Do you see what I mean?

Hey, I emailed the camshaft ebay seller to see if he has a dyno graph, and this is his reply:

we do not currently have a dyno graph. These
camshafts are made to be run with the your stock
valvetrain. These cams are good for 5+ whp from
about 3K up with your stock setup, with headers,
an intake, etc. we have seen more than 10 hp to
the wheels.

you will be very happy with your car after
installing the cams.
Hope to hear from you soon

yeah that is supposed to be like it. thats the back side of the pulley. its to keep the specs. w/p pulley and alt pulley are virtually the same specs except for diameter. so i basically just steppped up the diameter for the w/p pulley and added a few design elements since its a 3 bolt pattern.

refer to the second pic of the alt pulley. the boss (nub sticking out) is the same feature as the '3 point wing nut' on the back side of the w/p pulley. the boss is just a lil different but serves the same purpose.

see what i mean?

[mx-3_4evr]

It still doesn't convince me, I already have an exhaust cam that I will be using to do the exintake mod. There are proven dynos of the exintake cam compared to the guysinashed.

[mx-3_4evr]

I don't think you know what I'm trying to say. The way you are holding the stock water pump pulley is how it's installed on the engine. meaning that the pulley's offset helps it go closer to the engine. In your design, the water pump pulley's design, helps it stick out. So I'm talking about the offset. Look at the water pump pulley on your car and see what i mean

[j.sher350]

AH!!! gotcha.... yeah i see what ya mean. k ill redesign it then. wont be to hard. thanks for that antonio.

[mx-3_4evr]

No problem man, just here to help
