most probably doug if you actually drove it fast they would probably need checking every time you come on boost lol
it is advisable as a man to check your nuts regularly roflol
hi ya mate where did you get the polished damper mate??i presume they can fit on a T34??
I have got a baileys one i presume due to the fact it has not got any dampening effect this is why my bloody turbo bolts(turbo to manifold)undo over a period of time!
not mine m8 just a pic to show steve think rsnissan's car
harmonic resonation is a characteristic of the yb with the 2wd manifold hence why the guru's at coswoth fitted a damper as standard
it has nothing to do with the turbo coming on boost but the resonation can seriously affect the turbo
Thanks Tony i was just putting 2 and 2 together as steve had issues with his turbo thats all
what dose the harmonics feel like when on boost ? would i be right in saying it feels rough

lmao at the driving fast its a collectors peice now so got to take it easy and i do take my nuts regular specially after a good scrub!!!
hmm me thinks i will get one of these 500 dampers still got my standard one somewhere but prefer the look of the 500 ones
As i am a lazy bastard where caan you get these from
bring the engine up to 3k revs car static and at normal operating temperature,
increase rpm by 100 rpm increments whilst watching your turbo upto 4k rpm ,you will soon find the harsh spot for your engine.
If you have no damper fitted or it is worn out or incorrectly set you will see the turbo jumping around
my shitley damper resonates around 2750 with no load and a almost brand new turbo, so its nothing to do with a fucked turbo. Its because its rose jointed and they vibrate causing the noise. Mines just pissing me off now, so im ditching it in favour of the T4 damper. I also need to know how it fits, lol.
I always thought bailey type dampers did fuck all.... What do the dampers actually do then? As I had terrible trouble with studs falling out of the exhaust on my old T34 saff, I take it the spring is the important part, to take the harshness out of the vibrations?
Also, I take it bailey type "dampers" are actually useful for taking the weight of larger turbos to save manifolds cracking etc?
the dampers are friction dampers which reduce the harmonic resonation
the standard cast manifold can support the weight of any large turbo it's the tubular ones that can't and require support brackets and braces
harmonic resonation causes studs to fall out and or brake it also affects the turbo operation

jim you want to be realigning that one it isn't on properly
that would be down to me, it was off the engine so i put it back on for photos, but tbh i dont know how to allign them correctly or even that you had to !, ill leave that to the old chap lol
Tony, what is the actual problem then? I am trying to imagine what the damper actually does? I take it the vibrations/harmonics try to twist the manifold/turbo, or is it just pure frequency vibrations etc that the damper trys to eliminate/ move out of range?
I take it the natural frequency of a 2wd manifold is the cause of the problems? How do different size turbos affect this?
harmonic resonation is a characteristic of the yb with the 2wd manifold hence why the guru's at coswoth fitted a damper as standard
it has nothing to do with the turbo coming on boost but the resonation can seriously affect the turbo
I would say that is more than likly the cause of my turbo faults NO DAMPER and 4 turbos
