haha...you are still young!
Here is a video of my NSX on the JB4 Map 3 (98 Octane) vs an Audi R8 V10 (stock except for an aftermarket exhaust) - time slip at the end.. I chatted for a while with the owner of the R8 and allowed him to take the NSX for a short spin. He was blown away and said his next car was going to be an NSX. LOL

excellent stuff! Soooo many people underestimate the power of the NSX...until they have to face it.
It surprises me as well considering the weight but it all works out really nicely!
always better to look good than feel good.....
sbkim: I am really happy with the performance of the NSX: stock or with the JB4. I do feel I can get the equivalent of a high 10 second run in the car with the factory stock map. Knowing that I ran a 7.14 in triple digit weather on a fairly slippery track (3.00 V Box 0-60 when I have done 2.82 before I got the JB4 on a regular street in cooler weather) I am confident the car has high 10 second potential factory stock. My car does have the full carbon fiber package and ceramic brakes and 16K miles on it so is well broken in by now. I have only made 1 pass with the 93 octane map and that was a 7.01 and in 95 degree weather. So I know the car will go under 7 secs on the 93 octane map - so maybe 10.7 to 10.8 secs in the quarter mile. And then on 98 octane map I think 10.5/10.6 sec potential is there under the right conditions.
As far as technique goes 1 obvious step is to run off the AC. I do also try to let the car cool with the deck lid open in between runs. The car loses power if you do back to back runs (Maybe that's a good selling point for the Science of Speed intercoolers). Getting to the starting line at the track requires crossing the burnout box which gets hosed down with water. The track is too narrow to properly drive around out so usually at least the tires on 1 side of the car are wet and you can't do a burnout to dry them off. I do 1 quick start with launch control prior to pulling up to the starting line. Just to get debris off the tires and to make sure the trans temp is up enough to allow for the launch control to work - if you let the car sit for too long you can get a message that says you cannot engage the launch control due to your trans temp being too low. When I stage the carI try to make sure I position in in the "groove: where most cars carve out some of the surface due to repeated launches. This part of the track has more traction. If you position yourself out of the groove you can give up a whole bunch of time. As you know the launch is everything in getting a good time. For example, on Map 3 I got some 2.79 sec 0 to 60 runs in the groove. One time I got out of the groove and got a 3.29 sec 0 to 60 and my 1.8 mile time dropped from the 6.9s all the way to 7.29. So 3 tenths of a second right there.
When I am doing runs on the VBox on a regular street if the traction isn't good then I don't use the launch control at all. I can get a better 0 to 60 in sport mode doing a lighter brake torque on my own.
Finally, don't for get about reaction time, which although independent of your elapsed time, does allow you to get to the finish line more quickly. If you give up too much time on the tree you might actually not get to the finish line than your opponent even though you run a faster time. Likewise, getting a better reaction time than your opponent widens your visual margin of victory though it has no effect on your ET. The same thing on the street if you are racing someone. Give up a half second by mistake and you can have a difficult time trying to play catch up.
I am running Continental Contactsport 6s. When I purchased the car it had 9600 miles on it and a set of Michelin Pilot 4S tires. The best I could get for 0 to 60 mph on my Xbox with a 1 foot rollout was a 3.18 secs. And that was attained without using launch control because the tires would spin too much with a hard launch. At 13.9K miles I got a nail in one of my rear tires. Rather than replace the tire I got a new set of Continentals from Tire Rack. I had wanted to try the Continentals out anyway because I noted that Acura had changed their 0 to 60 time from 3.0 to 2.7 secs when they started using the new Continental tire and I figured the tires might have a lot do do with the improvement. That night I took the car out and ran a .2.82 and 2.85 sec to 60 time with just myself in the car and 2.92 with my GF (all 120 lbs of her) in the car - with well over half a tank of gas in the car. When I had the Michelins the car would smoke the tires when downshifting into first from a very slow roll and then break the tires loose on the shift. Launch control wasn't usable at all. Anyway, very happy with the Continentals. And yes there are drag radials and street performance tires that might provide even better traction but I don't want to slide around badly when it does rain.
Would you say the install of the JB4 is easy or should I take it to a shop for the install? I’d like to do it myself so I can remove it easily as well.
Also do we know for a fact this voids power train warranty or is it not detectable?
