Default HOT Tip-HOT I say!!

Hey all,

If you havent done it yet-for goodness sake-put the ceramic diff balls in your diffs!!! Holy-cow are they smooth.

I put a small drop of Associated Stealth lube in each hole in the pulley and dropped a dry ceramic diff ball in. Then assemebled with dry dif rings and voila-super diff!! I used Si3n4 Grade 5 balls. Yes-expensive but worth it.

Ray likes his balls hard and smooth.

Anyone remember VRP (Verona Racing Products) from the late 80s? They called them Precision Differential Spheroids!

They ran ads in the magazines showing a spoof of Married With Children. Peg comes in and says "Are you playing with your balls again, Al?"

Yup, I have had 1 set of Corally ceramics in the diff of my car for about 6 months, and STILL butter smooth. Have never pulled the diff for a rebuild. I sand the rings using 800 grit so they are perfectly true.

Who can ever forget VRP...... with the Hot Pink and Bright Blue stickers.

I still have some of the hot pink diff lube. Still works as good as anything else out there.

Default Corally parts

Hey guys I'm looking for some Corally parts and need them asap

where can I get a oneway, diff outdrives and ceramic diff balls, shipped to Los Angeles by Monday (or Vegas by Tuesday)?

I've tried speedtech, but they are out of this stuff. Also the corallyusa site doesn't offer 2 day shipping... any help would be appreciated

Got the new RC Driver magazine yesterday, and I noticed something different in the new Corally ad.

The rear body mount brace is different. Is this another kit upgrade, just like the white diff pulleys? Same part number?

The rear body post plate has changed a little bit. It has now 6 3mm holes for the body posts, instead of 2 3mm and a bigger hole. So it will be easier to mount more bodies (for example Mazda 6). Part# will be the same as the old one, just like the white 42T pulleys.

It are just some little improvements. But I haven't see the ad, just know it.

Default Motor Fans

This has probably been asked but I can't find it so:

Are motor fans worth it? Where can I purchase one and how is it hooked up?

And naturally, how does it mount to the RDX?

Well, I happen to test this weekend with Jeff Brown and we ran about 5 packs without a fan. The endbell temps were around 180deg. We took a Novak fan and Jeff made a lexan mount for it to hang over the endbell and shoot directly down onto it. Well, the results were better than expected as the temperature dropped on average about 45 deg. On 3 different runs the endbell was averaging about 135 deg after the 5 minutes. We were impressed. Picture shown below of Jeff's RDX.

Were the lap times any different from no-fan to fan? Cooler is one thing, but if there is no gain on the track, the value of the fan is in question. More battery left? Less wear on the brushes or comm?

The question is, even if it lowers the temps, is it more valuable than, say, a 12-fin snap-on motor heatsink?
