Anyone got a cure for wind noise at 166mph?

Silver Surfer:
I was in 5th gear at around 130mph, by the end of the video the revs are at an indicated 8000rpm but it does seem to over read so I believe that was around 7700rpm. The 4.4 final drive definitely helped but the JDM gearing probably didn't. Either way the car is in a high bhp powerband on every change so the difference would be minimal.

James:
Which video had a GT3? They all look the same to me
The black porsche only managed 167 when I look closely at the number on the beams, it just got to that speed a lot quicker! Probably all that downforce affecting it's slipperiness. I believe the other porsches were modified.

I didn't do any hard launches with a car beside me, I probably should have!

I would've thought a GT3 would get more than 167 - they were getting mid 170s at the events I have been at.

You now have the NA NSX record! How much power do you have? Our NA2s struggle once beyond 160 and changing into 6th.

I gave the door/window seals a couple of good doses of Holt's silicone & rubber lubricant. Lots.

It's not completely cured it (the passenger window stops a tad too high & pinches the seal) but it's gone from irritating at 80 to irritating at the sort of speeds you are talking about.

Probably if you could contrive to drown them & then leave the windows down for 24 hours, they'd come back to shape fully. Must try that...

Well done Ed... Certainly did Kevin proud after all the mods he has done to get the car to current state.
I am sure the gearing he has changed to lower ratio allowed the car to accelerate on the straight better.
Did you get into 5th just before you cross the laser timer or well before?

I have only just been alerted to this thread and the Vmax. Have to say I am really happy. The car has exhaust after the dyno day, might have a bit more power than it did back then. I think the corner could have been a bit quicker though.

I can't remember which final drive ratio your car has in it 4.44:1 or 4.55:1? The revs, on the rev counter in the video, look about right for a 4.55 i.e. about to hit the limiter at 166mph.

Either way your car is perfectly geared for VMAX at this event

Cheers

I have the OS Giken LSD + 4.4 final drive. As far as I know there is no such thing as 4.44, at least from OS Giken, the 4.44 is a typo on the SoS website. The rev counter shows 8k rpm but that really means about 7700rpm, my car hits the rev limiter at an indicated 8.5k rpm. Also the shift light comes on displaying higher rpm than programmed.

This would mean the gearing could achieve ~175-176mph with the current gears and tyres.

I came across this video whilst someone was loading up the previous vids on their virgin media tv:



I did a few of these at the end of the event which led to me needing a new clutch! More due to a problematic clutch that absolute wear, it still doesn't slip now.

[NSXGB]

Sounds good Ed. When is the next one?

I thought someone (Leigh perhaps) clocked 185 in his on the autobahn... 185 on the GPS?

I think a standard 02+ would do around 170 given enough road.
