Wheering noise...

when i am in 1st or second i head this wheering soud. normaly i run premium gas 84 octane and now i used 87 octane… could this have anything to do with this?

94 octane i mean

I don’t think that is the problem since you have an RS… If it was a GSR, it would be something to be looked at closely. Describe the noise some more!

the whirring noise has never happened to me before it almost sounds like the timing may be off i read in an article that is my timing is to advanced or to retarded the engine can make this noise i believe… if anyone know please post refuring article
