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

[mx-3_4evr]

Got the pistons and rings today! Crankshaft getting grounded to .010 for main and rod bearings. So I just ordered the ACL RACE bearing kit. Should have this block ready by next week

[j.sher350]

ok sounds good. i'll rework it then.

[mx-3_4evr]

Another option is the 94+ Aspire pulley with no A/C or P/S.

[j.sher350]

are these parts separate??? or joined in between by some sort of a brace????

talkin bout the outter ring and the inner piece

[j.sher350]

hows this look??? gettin any better?? haha

i would roll with this one...

[mx-3_4evr]

that looks more like it. I wonder if the 6 conections are too much to absorve vibrations. Maybe 4 would be more like it? IDK I need some imput

[j.sher350]

lol yeah i had 10 in there...but yeah maybe 4 would be better.... i agreee... need some input... from anyone really

[j.sher350]

changed to 4. gonna have this prototyped tomorrow.

w/p prototype is being made right now. should be done around 3 am?? 11 hour job

[j.sher350]

got the w/p prototype back today!! soooo sweet!!! and it fits!! holes line up and everything. so excited to see the final product.

[Mazda_Powered]

neat, i'm curious on the outcome.

are you willing to make more of these crank pulleys with the vibration dampening?

[j.sher350]

yeah just depends on when i get the plans made up and stuff. might have to wiggle it out on my own. guys in the shop are pretty busy so we'll see..

but yeah. as of right now i'll be making...

Crank pulley - 3x
Alt pulley -2x
W/p pulley- 4x

so yeah i can prolly make another crank pulley for ya. not gonna promise anything but yeah...

[mx-3_4evr]

Pics or it didn't happened lol

[j.sher350]

haha currently switchin phone companies so i cant send pics to my computer. and dont have a cable/ memory card. it IS however a tad bit smaller. but this should be no problem.

sorry bud

[FE3-323]

the results are looking good guys. keep up the good work

The pulleys you are making look sweet. You don’t really need the elastomer ring. The crankshaft pulley is not a true harmonic balancer. Best info I have seen is at this link . In the FAQ on unorthodox racing they say essentially the same thing. Almost certainly the crankshaft is internally balanced and the crankshaft pulley itself only needs to be balanced independently. The rubber on most crankshaft pulleys is to reduce noise and vibration with the driven accessories. You don’t need the rubber ring. To make a difference you would want the pulley to be made in 2 pieces.
