Ive noticed my car does some funky Shite at 6500rpm

when im really hammering it hard it does this funny kinda splutter and backfire at 6500rpm

ive spoken to tobyG about it and he says his does something similar at that high rpm

 

is it a limiter to protect the lump?

 

ive done it in 2nd and 3rd a few times and once in 4th and on a large downhill bit of motorway i did it in 5th....

 

is this normal? other people get this? :madbugger: :tongue:

Ive read before that the Zetecs can rev up to 7250, but its not really recemmend unless you have the approate chip and throttle bodie setup. Im sure that you could do it, but 9000 rpm? Doubt it. The st170 only hits 7500, and the VVTI (varible vale timing as seen on the Puma etc) kicks in at 6000 rpm, so i doubt it..............
