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

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

Paul

bud-weis

I doubt you could feel anything at all?? im guessing the frequencies would be way too high to hear it too.

I have had turbo brackets crack when using a bailey damper before...i switched to standard 2wd and it was fine.

In that case why would steve be changing his

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

did 4x4's have dampers? As i havnt got a damper on my turbo/engine. its got a 200 block but its for a 2wd car.

4x4's and escort cosworths had a different exhaust manifold so a damper wasn't required

boXXer

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.

easy when you know how to fit them i charge 15 quid to build them up and fit them

R5FORD

so id only need one if i was running a 2wd ex manifold.. im 99% sure im runing a 4x4 manifold

boXXer

yeah i can imagine they are piss when you know how. We need some Schematic drawings ;p

you can come fit mine for £15 if you dont mind the drive, lol.

You would if using a 2wd one

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?

Turbosystems

iTrader: (5)

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

J1mbo

iTrader: (1)

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

you can't get the staff these days Jimbo lol
looks like you have put it on how it was jimbo judging by the pad wear

J1mbo

lol

when i took it off i put the clamp back over it to hold it all together as is so more than likely have, see im not all bad

Great topic.

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?

boXXer

Excellent pics Jimbo

So how do you set them up correctly?

J1mbo

iTrader: (1)

if rainbird saw that he would faint ! im renowened for blurry pics

i am still wondering this too

RS500/364

I would say that is more than likly the cause of my turbo faults NO DAMPER and 4 turbos


The bit that spaces to help fit !!
