Subaru detonating problem
Hi, I have a subaru sti 2007 and at 5500rpm it loses power and makes a loud rickety noise, I took it to a garage and they said its detonating! I have got it booked in at marlin motors on Tuesday and hopefully they will be able to fix it for me as they have a 4wheel drive rolling road, I use tesco 99 Ron and shell vpower. Has anyone else had this problem? Does anyone know what may of caused it? Thanks in advanced for your help

Yeh let's hope so, the garage did say that it was detonating at 5500rpm, this was when it was losing power and started making that loud rattling noise. If the car was detonating then would you only hear it at 5500rpm ? Are there any other symptoms to look for if it was detonating do you think ?

How did they diagnose it as detonating ??

I took it to the garage where I bought it from, I told them what the problem was (losing power at 5500rpm and making a loud racket noise when it gets to 5500rpm, 2 mechanics took it for a test drive with "live data" and they came back and said its detonating, hopefully it's not actually detonating and may just be a lose spark plug or something

if you can heard it on a video then its not det mate. Det you need det cans to hear. Get it to a decent specialist for them to have a listen, API is down your way i think?

Incidentslly the first time it happened i was having a dice up with a classic scoob on the m4. 120mph ish and the result was nice hole in a valve.
The second time, different car and engine, same sound.
That also resulted in a burnt valve lol

The car is standard as far as I know, but the thing is it drives perfectly in 1st gear all the way to 7000rpm and also still drives normally until 5500rpm in second gear , so if it was detonation then would it still drive normally up until 5500rpm in second gear does anyone think?
