probably a belt slipping or something is vibrating because its not tight enough. does it happen when you free rev it?or only while youre moving?

if you can get someone to rev the car, you might get a better indication of where its coming from. i rekon exhaust or something simple like that. airbox, anything thats connected to the engine thats come loose slightly.

yup, something is loose, sounds like a harmonic resonance thats causing something to vibrate

is it metallic sounding?? might be a blown gasket too, but unlikely

hm.. not quite metailc but it sounds like sumthing rubbing against the chassis or sumthing at high speed

u can feel the vibration inside the cabin too

lol already did all that

yeah feel the vibration inside and hear it

and also the noise is there from outside too

checked all belts cuz of that i spend 1.3K on a full service staright after i got my car

but the noise was still there

im ruling out diff problems too cuz i changed the syncro and all that setting around and the noise was still there

it's gota be sumthing mechanical

I know that sound.

It started after my turbo was done, but only sometimes and under full boost (yep around 4k).

If I take my foot off the accelerator, the noise disappears. Then it says gone when I put my foot back down.

My mates RS is starting to do it (so he says, I haven't heard it).

It is not possible to replicate as it happens to me us at random times.

No Danny, I do not know what it is!

Thought it might be an oil supply prob to the turbo, nothing to do with belts

I am getting the same sound, and have done since i got the car about 2 months ago. hasn't gotten any worse tho, and doesn't happen alll the time. You're right about the rev thing - it happens to me at about 3 grand, only while pulling through torque at higher gears. if the auto kicks back, or I use manual mode, then it doesn't happen. feels like about 3rd or 4th gear. It's really hard to say the sound is consistant tho, I think it doesn't really happen all the time.

only under load

and no it doesnt get louder on speed

it's not constant..

only at 3-4K rpm only half thorttle then when i full throttle it it goes away

Sounds like Turbo time!!!....sounds sort of like a slipping clutch or a rattling sound?.....only under load? Is it there all the time? Does it do it under full throttle?

    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
    • Sounds like the oil pressure light is wired into the oil temp sensor... As it warms up, resistance on temp sensor reduces, hence more current can flow and the dash light gets brighter.
    • Got the front subframe and suspension in.    
    • If it's cold in summer, then no issue. If it's cutting out every few seconds and you're not reaching your target temp, then there's an issue. One could be the pressure switch and the other issue could be the temp probe inside the evaporator.
