Hitting the rev limiter in an MC Shift manual mode

Each to their own of course, but suggest you try out the entire spread of revs on offer. My own base model QPV 4.2 is a civilised but sporty saloonup to 5k. From there to the redline it just makes me laugh out loud and think I am a race driver. Somewhere around 5200rpm the magic happens and rate of climb increases. Every gear change take at redline starts again from this point. Like a race car. In my 5 metre long, double glazed, leather lined Limo. Ridiculous and pointlessly childish. No wonder many do not visit that zone of the tachometer.

The MC-shift is even more pronounced noise (engine + gear change)

Haha I know. I simply need a stretch of road long and clear enough without getting penalty points! I've seen a few posts here about issues occurring after 7k revs so I'm a little reluctant to explore this far but then again, isn't the car designed for this reason! Well the engine anyway.

Never heard of those issues at all.

Ive seen posts about issues after people giving their cars ‘the beans’. I take this as flat to the mat, thus over 5k revs at least. More than anything though, I want to slowly explore the limits of my car. Next outing ill give 6k a go

Please keep them to yourself, I’m not going to change how I do my ‘research’ :p

No point in doing it slowly! Seriously, just find a decent bit of road, plant your foot and hang on. If you put it in Auto it'll probably upshift for you, otherwise leave it in 2nd and bounce of the limiter!

I think if owners have problems up to and including bouncing off the rev limiter they need to book their car in to get fixed.
In my experience 4.5 years of ownership and 20,000 miles....... they come into their own at the between 6000 rpm and their limiter.

I tend to agree that there's more to driving enjoyment than making noise. The asbo brigade being, well, just that ….
Someone here commented that Maserati is "all about the noise" and, imo, couldn't have been more wrong.
Each to their own of course but I seem to recall a comment in the handbook about not driving at top speed for more than 30 mins :smile:
This seems to suggest the occasional topping out isn't a bad thing. A free-revving performance engine is capable of much more than you're asking of it.

I'm completely convinced that an engine should be cycled to its rev limit frequently. Inertial energy. Rev to 50% of its designed limit and the internals stretch to that 50%, leaving wear in that sector. You rev to 100% and the wear is more even. Imagine the scenario of an engine babied for 10K miles, and then given a proper thrashing. Not good. Racing bikes (I know, I know, very different) are often broken in at full beans.

YMMV (I'm not paying repairs on any spun bearings or bent rods :)

As I said earlier, the fact that on an mc-shift the mc-shift mode doesn't even activate until your right foot is at a minimum of 80% throttle and over 5500rpm speaks volumes.

If you want to cruise at lower rpm, buy an auto. ;)

My thoughts too. The ZF box does 90% of what the audience for these cars will need. Luckily for me and a few others Maserati kept the 6 speed as an option. The ratios appear perfectly stacked to keep the engine singing. Sometimes I wish they were spaced unevenly so I could experience the unbridled joy of revs approaching and passing 5000rpm. Just means I have to slow down, drop a ratio or two and repeat. First world problems for MC-shift / duo select cars. :)

Just as an update to this - it was indeed the alternator which was knackered; whether that was because of hitting the limiter, I don't know, but I'm glad to be back on the road and getting 12mpg again after driving around in an EcoBox for a week. :)

High rpm on occasion is good for an engine, knocks carbon off of the valves, and keeps a ridge from being worn in one spot in the cylinders. Too many engines spend thousands of miles at low rpm then get driven fast, rings hit the ridge and break.
I've never read the GT or QP owners manual, but the 4200 manual says that "shifts are faster and more precise at wide open throttle and above 6000 rpm." So the proper way to drive it is with your foot to the floor. Only in Italy....
