quite... I couldn't imagine it at 6000 rpm. It sounds like its going to
detonate at 3500 and the police can hear you coming a block away...

You must still have the computer running it or in the loop somewhere or
are running an ethanol mix.

I can pull out to almost 55 mph in second when hitting 4500 rpm using 91
octane gas and get 19 US mpg.

It runs like a pig on ethanol mix.
