What's that I smell?....Oh yeah...it's Bull$HIT! Come on HMF. I bet it would sell!

Duals sometimes limit or kill power.  It may be alright with different cam and compression, but on the raptor 700 it likes backpressure in order to make its full horsepower



Maybe some low end, but the top-end gains would far outweigh the low end difference.

Limits power eh.....
Cant say what a stock 700 would do on a comparison but heres my 727 with duals vs. "small" single:

great post velociraptor. Explained my point on the button. A 2hp loss is more than returned with an improvement of almost 15 over a broad area at high RPM.

Actually its 17.Xrwhp @ 8000rpm

we need to get everyone on the forum to email them im sure they will make something...I think duals would be easier to make then a single

well sooooorrrrrryyyyy!      Bet you would be short shifting that one.


Air flow is air flow......and that is what we are all after. I like the sound/performance of my HMF... but just would be cooler x2 as duals.
