impressive numbers...
hmmm... Those 1/4mi numbers are very nice! Most bone-stock NA1 3.0 5spd NSX'es I've seen usually have values of 13.65-13.85 in the quarter mile, and 13.25-13.35 w/ aftermarket headers/exhaust.
Were you running on street tires? I am envious of all of you European NSX'ers in that you can buy the readily available Yokohama RE-048 tyre (NSX-R spec., semi-slick R compound). Unfortunately, this tyre type isn't offered in the USA.
Driver's skill/technique combined w/ an awesome tyre such as the RE-048 make the NSX beyond words! 8)
