Rep Power: 0 yeah when i first saw i was amazed here it is.. they arent allowed to post the chart as of yet.. but here is him saying it..
UPDATE (21:35, 14.Sept.05): I just got a call from Shawn and today another 2006 Civic Si (preproduction, of course) was tested on his dyno. This one had 3500 miles because it had been driven cross country from Michigan. Obviously, the break-in mileage paid off because this car put down 209hp, in a fully stock configuration. With the airbox cover removed, the number jumped to 218hp. Shawn is not near a computer at the moment, so we don't have the dyno plots, and the car isn't ours, so we may not even be able to post the plots, but it's clear that our car isn't a fluke, at least amongst pre-production Civic Si's. jp

Rep Power: 264 honda engineering never ceases to amaze me... and it seems like they WANT us to modify the cars. i mean, u get that big of a increase when you remove the airbox. imagine what minor bolt ons will do for it...its like they make the car less powerful just to have us buy them and modify them

Honda puts some serious R&D into their power plants. Each one does what its meant to do extremely well.
