30th September 2006 Rolling Road Day

[Paul]

Indeed ... a great morning ... shame my new air box actually reduced top end bhp rather than aid it ... albeit only a reduction of 3bhp at the very top end of the rev range ... however every one counts ;-)

Having studied the two runs (Apexi 'v' OEM filters) on the combined printout the difference is so slight and overall there really is very little difference on the whole ... I think I'll swap the OEM one out again and put the Apexi filter back on ... the more enjoyable cabin sound from around 4,000rpm will be worth it.

The OEM filter provides smoother plot lines and under 3,500rpm it has roughly a 5bhp and 10lbs/ft advantage over the Apexi ... but from 3,500rpm to around 7,200rpm there really is so little to choose between them it's hard to tell them apart ... both the bhp and lbs/ft lines are better with the Apexi from around 5,900 to 7,000rpm ... albeit only about 5bhp and 5lbs/ft ... so I'll be keeping revs over 3,500rpm when I want and enjoy the sound and enjoy the extra lbs/ft and bhp between 5,900 and 7,000rpm :-)

There were seven NSX's in total ... I think Simon made notes on types and bhp figures etc so I'll leave him to put up the 'results' as it were ... good job I've got strong shoulders as I think I had to hold up everyone else above me :!:

There didn't seem to be a shortage of cameras, still and video, so I would imagine there will be some additional shots in the gallery, or here soon but for the time being ... here's the line up of NSX's ... minus Mitch who had to depart around midday ... plus SportyKing's mad mad MAD MAD Ariel Atom!

Note the shot of 'Biggles' making his departure ... shame I didn't get any of him screetching off down the road ... mind you I'd have to have been quick ... he was down the road amid wheels struggling to get grip and a wonderful howl from the exhaust ... I don't know who was smiling more ... him or us as we watched :!:
