350i top speed

Not sure it's all about speed
Acceleration is much more fun than blowing the engine up revving it to red line !
Mind you my 350 had on several times indicated 140 on speedo, but on sat nav was doing 130. (Somewhere in south of France with roof up
)
The 450 on the other hand would go to 150 on GPS but you needed 3 lanes or wide runway
to go in a striaght line safely

to go in a striaght line safely A few years ago a previous owner had my 450 on a track day type event. On the straight/runway ( i can't remember where he said he was now ) he had a skyline on one side and a Griff on the other. He kept with them and on returning to the pits asked the two drivers what they were showing. They both reckoned they were nudging 160............
I wouldn't fancy it personally.

On an unrestricted Autobahn somewhere in Yorkshire :cough: I got my 390 off the clock at 160 late one Friday evening. It did need a good couple of lanes to itself and I was bricking it for more reasons than losing my licence.
Naturally I scoffed at the indication, after all 390SEs were only supposed to be good for 146 when new.
A year or so later I took Talbloke down to the Wedgefest; on the way back up he had his Garmin running, and that showed the speedo to be only 3% high at 100mph. I was even sceptical at that
Then I got my own Garmin, that I use on the bike, in the van and in the TVR, in which it agrees with Roger's unit - 100mph indicated is 97 on the satnav.
On the bike, in Germany, on a genuinely unrestricted Autobahn I have seen 135 indicated when the bike said 142, and the usually quoted maximum for ST1300s is 144.
So the satnav would appear to be telling the truth. Thus, on a brief thrash in the 390 where the speedo said 135 and the satnav said 127, there's a large non-linearity developing on the TVR speedo (+6% by that stage) so if we extrapolate from that and say that at 160 the error was +10%, I'd have actually been doing 144, not far off the claimed top speed of 1985.

142 flat out with a 95k 3.5 motor and an FHC shell. No wind speed that you could notice . Felt alot faster at the time as wedges don't exactly seem to stick the the floor like glue. I think I remember this was about 5500 rpm. I'm sure the bigger engines are a bit faster but wedges have proper aerodynamic problems compared to modern stuff.
