This is the stuff:
HHS-K works great, just don't get it anywhere near bearings, as it's a bit thicker than oil once it's application agents dry out

Thoroughly clean DCJ's with motor spray, and give them a spritz of this stuff every few weeks or so, also use it to lube blades, or pins

I would estimate the release date would be in August or September. Pricing, I would estimate around 20,000 Yen or $230 USD range.

Man I was off by only $10, somebody buy me a lottery ticket.

Default Gearing help

Can anyone offer any advice on gearing for an 8.5 speed passion motor?

I'm planning to run 48 pitch gears. I'm running a BD5wxi on a tight carpet track and I assume that the internal ratio of 2.1 is the same as a BD7.

It would be great if someone could give me a starting point.

Cheers

David

i run thicker oil when the track is high traction. Its can reduce traction roll as it reduce the car response.

But even in low traction track, i also run thicker oil. i found it make the car more easier to drive. i ran 5000 - 7000 oil depend on situation.

So a basic rule: a thicker oil on a grippy track, and thinner oil on a slippy track? is that correct?

Was kinda waiting on everyone's response here

I've been running 1k, tried 3k on carpet once, but it compromised corner speed

Guess its a tuning tool for feel ?

This is always with 13.5 blinky for the record

it will be depend on how you want the car to react and layout....i would start with 2k geardiff oil ....try yokomo geardiff oil as it special formulated. It's more consistent than silicon oil...

I think 2000wt is the ideal starting point especially if you're at an unfamiliar track. Works 90% of the timefor me. I change the oil to alter the way the car enters the corner and then work my setup around it. Thinner for more aggressive corner entry at the expense of less high speed steering and thicker oil for vice versa. For most outdoor tracks, you can get away with a thinner oil and it won't upset the balance but on carpet, it's very sensitive to viscosity changes.
