Hi! From NZ and a quick question

[Rahzyx]

Hey! I’m Rahz from Wellington NZ. I have a deep love and appreciation for RB’s and Im so happy to finally be here  

my question is:

We’ve just done a new clutch (D1 Racing) change on my turb’d R33 and bled the clutch but when it’s driven at a low speed in a higher gear it creates a low rumble vibration and noise. We’re trying to figure out what this is. Everything has been tightened and torqued to spec. 
Has anyone had this issue before or know what it might be? 

Thank you

Doe that clutch plate have a solid or sprung center?

Spring

 Well there goes my first theory.

Here's a silly question, did you previously drive at low speed in a high gear? Or are you trying to find weird noises?

[Rahzyx]

Hi Ben,

No. We’re thinking it may be the countershaft bearing. Will find out today

Only when you put a little load on it, or at any load?

Because the former is normal-ish.

An internet diagnosis of a noise is pretty hard, especially one that doesn't seem catastrophic or even to be concerned about.

Hopefully it all checks out when you dig deeper. Typically straight after doing things you tune into noises that were normally there, but your mind makes you think the worse. opposite of when people change their oil and feel like the car is heaps faster!

I'm pretty sure my car picks up 50kw after an oil change

hi and welcome from another welllington skyline owner.

did you replace the spigot bearing when you did your clutch? maybe take it into WAGS and see if they have any ideas

Can you define what low speeds and high gears are?
I don't drive below 2,000 rpm on my cars, they don't like it (RB26 and EJ255).

RBs with VCT will happily pull 1500rpm in 5th. So long as you don't open the throttle too much.
