Just wondering if anyone has installed naca ducts with tubing to help cool the diff. Anyone wanna chime in and advise if it will/will not work?

 

never thought of that but sounds like it could be a good idea.... but what do i know lol

 

A PuddyMod clooling cover would be a more easy choice

 

^^ Haha- you make all the toys. Thanks again for the diff. Still on the brake-in period. Forgot how noisy the 4.57's are.

 

Very cool...

 

Truth be told the S2000 rear does not have a heat problem for say. It does not boil oil or it out like the Nissan R200. I have ways to fix the R200 from boiling oil
Duct or venting to the rear can’t hurt but, may not be a necessary for the S2000.

And yes, the 4.57 likes to sing

 

4.57... I wish my diff sang... I do too much highway driving though. The only things that sing in my car are me and Miley Cyrus.

 

Nice work PuddyDad!

Are the original 4.57's (7:32) still available, as in new, never used?


Long time ago I took some temp readings in these spots.
A (both sides) = 63,5 C. (average)
B (both sides) = 62,8 C. (average)
C (both sides) = 61.8 C. (average)
D = 65,4 C.
E = 69,8 C.
This was right after a 37 km spirited drive.
Outside temp at the time was 22.4 C.
E was the hottest as there was a little bit of oil around the fill plug so the heat transfer was best.

These temps are no problem IMO.

Diff water is... haha!
Yeah I know.. its getting old.

 

The reason I was asking was I was planning on making rear brake ducts as I have a front BBK. This was the pads should be at a more even temp s the rears are small and non-vented. I was thinking I could buy one of those scoops with dual 2.5" outlets, and direct the remainder to the diff.

I would think that cooling the rear brakes may prolong the life of the wheel bearing/hubs. Although I never took temps to evaluate the diff, front to rear, I've touched the rear wheels after spirited driving and they were hot, as the front wheel was near ambient temp.

 

No, they have not been made in a few years now
