You answered a question I never posed, I wondered if the etec 300 could be modified for more POWER.

Brian,
The only way to "push" any E-Tec (or ANY modern clean engine) for more power is to push it SIDEWAYS and install another one next to it!! (BTW, the idea for a twin-size bracket would really help resale value on that Seamaster!) Emissions regs have the OEMs on a pretty tight leash when it comes to souping up the motors. Not that it CAN'T be done by someone like Monte racing if they had a way to reprogram the EMM, but there is no off-the-shelf "tuner chip" you can buy to increase power.

However BRP uses the exact same E-Tec technology along with some variable-area exhaust ports to get 160 hp out of an 800cc production snowmobile motor!! It probably has to meet some sort of emissions standards, and that would translate to getting 680 hp out of that 3.4L powerhead! They certainly aren't working it too hard at a rating of only 300 hp! If anyone wanted to start a HP war with BRP, they clearly have the weapons to be seriously competitive, so who knows what they'll come up with in the future given enough market demand! Denny
