mostly it will give you a harder hit when you twist throttle. it might complicate fueling . with all tha air on demand the ECU will need some tuning. peek HP will stay the same. go to rider forume .com for a long list of info on this mod. i am happy without it. my bud did it to a ZX 14 and i just hated riding the bike .but that bike has 1300 cc and 170 HP. do your own thing.

It would be really good idea to add a PCIII when you do the air box mod, that goes for any bike that you do the modification to that is fi.

Once the bike is getting more air, it obviously is going to make it run more lean (plus, most bikes come lean from the factory) so it's definitely wise to get a PCIII to compensate for it, have it running as well as it can and correctly (ie; no stumbling, lean surges etc) for that matter. A lot of people will say the bike's computer will adjust for it somewhat in time, but in reality, by no means is it ever going to get the full benifit out of the modification and have the fuel to air ratio on par without a fuel tuner and a good map.

There are a lot of custom maps out there for different applications that you can simply download to your PC if you're not planning on getting a custom dyno tuned map. You can find these on forums specifc to the bike, PowerCommander's own website and aftermarket exhaust system websites.

I found this photo of a dyno run with an airbox mod a few months back. I figured that 7hp on a 750z was BS. So instead of paying $100 to try it out I just cut the top out of my $20 OEM airbox cover... The difference was amazing! It was exactly what my (then new) PCIII-USB was looking for. With the DynoJet Two Brothers generic map this bike came alive. It runs like a raped ape and definately made the frontend come up much easier with just a snap of the throttle. Runs great, no popping, backfires, great throttle responce and it isn't running lean either. The pipes are a little black inside (rich) and the fuel mileage dropped from 42-44 mpg to around 32-36 mpg avg. A custom map might help me out with the mileage or if you map it for max HP it could get less mpg. No free lunch I'm afraid. The beauty is it is so easy to change out a map you can do it in 10 minutes to match your ride that day. Canyons-Max HP, a 1,000 mile ride to grandma's, change to your (stock, maybe) gas mileage map! It is fun to play with once you figure out the software and how it effects you bike.
Airbox mod, Heck yes! Best thing since sliced bread if you ask me.

:eek:ccasion: i agree with u on that. gave me alot more low rpm power. small blips on the throttle will effortlessly lift the front tire. thats what i missed the most out of my superhawk i had b4 my zed. now i have that & a comfortable riding position. :D b4 that mod had to get the rpms up real high to wheelie.

More importantly, what gains did you see when you used the butt-dyno? ;)

You fellers have got me all excited! Im ready to do some air box cutting. Perhaps with this mod I can go back up to a higher gearing and keep my light front end. 15/42 is a lot of fun but I dont like the RPM's on longer rides.
