Neither will kill it on a modern engine with a rev limiter. Just don't do it on a cold engine as the oil won't get around it properly and make sure the oil is changed at the relevant intervals.

I never go above 3,00rpm until the temperature reads 91 degrees.
Jez said:This is what ive never understood when people say about their engines being on boost at cruising speed so they get really bad economy. Every turbo ive ever driven has been the same as the MR2's, ie, they will only boost with your foot down, you can still cruise at 6000rpm with no boost at all getting 25-30mpg.

thanks it just seemed a odd numberMuncher said:It's the minimum temperature the engine will sit at when in use really so it's a fairly good indication that it's at operating temperature, takes about 8 minutes and a few miles to get that warm.

Surely you'll only be on boost cruising if you need the turbo to generate the horsepower necessary to maintain that speed.Jez said:This is what ive never understood when people say about their engines being on boost at cruising speed so they get really bad economy.
