What speed is the rev limit in 5th?
At Donny I needed 5th in the Exige. Indicated 130mph! although probably closer to 125.

D'ya think I'll need 6th at the 'ring?
5th x 8,500rpm = 147.9 mph

I think you'll need your bravest trousers my good man.....

Given vmax is only a few mph more, it makes you wonder what sixth is for

I think there is every chance that when you change up, it will slow down ....

There are only three places at the ring where you might get sixth (I won't see it anywhere!).

Along the straight from Flugplatz to Schwedenkreuz - in the S1 I see nearly 130 there - in the Exige I reckon there may be a bit more in it, especially if you brake later and take more speed into Schwedenkreuz (100mph on the apex is normal for my modest pace). I would be surprised if you manage to squeeze in a change up to sixth, but I guess if you carry a lot more speed through the flugplatz that could happen, just. On my one trip there with the Exige (and with the 48s) I was exiting flugplatz just on cam in 5th, so you would need to be well into the cam to make it.

The start/finish straight is ~two miles long, though of course you cannot use it all on tourist days. Even so, if you had a shot at it, you might just make sixth, but crashing through the cones there is likely to lead to being banned

The other place is the straight after Pflantzgarten III - I don't go full bore until after the undulations and can make 120 at the end with plenty of margin for braking/turnin to Schwalbenschwanz (sp?). If you were on it from the crest of PGIII the whole length of that straight and didn't lose control/go airborne in the slalom/wave section, you could be seeing 140, but sixth? Doubt it.

A place where I don't think you'll see sixth is the Fuchsrohre - it is very fast and even 1.6 saloons see 120 down there - but I think it's just too short to top out fifth AND make the compression/corner at the bottom! But with big balls, who knows?

---

I have seen terrible crashes at each of these places, BTW, and I'll bet *none* of them were doing 147mph ...

OK, so more chance on the way there...if I take the rear spoiler off.

if you 'yota boys are too scared to go above 150, then i suppose that only leaves me.

Well with my S1 (which is what I'm taking) I don't think 140 is on the cards let alone 150.

It would be really cool to get a S2 exige or Honda-powered car and video the speedo/rev counter from say 40mph to vmax on a straight flat road, using all the revs in each gear.

The reason is that this would tell you the distance travelled to get from one speed to another. If it takes 4 miles to get from 145 to 150 then we know there is no chance of getting there on the track

Cheers,
Robin

P.S. Shug - do you want to bounce this to a new thread (e.g. wishful thinking from the rice burning boy?)
