well i'v read all your posts and side draft carbs don't work well on N/A rotarys .44mm is to small for starters, 48mm and up .Down draft webers are some of the best carbs for drive ability and simplicity .Don't waste your time with side drafts the max performance will always fall short .I know you already own the side draft , they suck ......start with dyno runs ,holly will produce an average of 7 more hp over the down draft weber , but the weber is the better carb for corner carving (no starvation due to fuel slosh in the float bowl).Please sell your side drafts you will not get what you want in terms of performance.

Your quite right on absolute performance but the side drafts with a wrap around
manifold gives you better torque down low for the street and makes it much more
drivable. Its all in what your looking for. You can't just say one is better than
the other, it depends on the uses and the drivers intentions.

I also agree that the 44 is a bit small for anything but a stock port 12A and even
then you will have some tuning to get it to a reasonable level. It will work but maybe
not as well as a 48.

sure ,if you want torque a wrap around will sort of work , but in my experience tuning will never be right.I would rather use the stock carb and save my $.The wrap around is not that affective , if you want more torque just put spacer plates between your carb and intake ,the longer the runner the lower the torque curve.

With a Nikki? I'd like to see that, post it up along with dyno sheets that show
how well it works that way.

nickki is a stock carb another stock carb is a zenith ,if you want dyno print outs go try it for yourself .Keep playing with those side drafts ,and waste your time.If you don't believe me call Racing Beats,the tech line will tell you they dont work right for a rotary motor .And raising a stock or aftermarket carbs height will change any engines torque curve lower( piston or rotor ),thats simple intake runner theory.
