as far as your statment about rotaries not being competitive is bullshit , we race nationaly in E production, at the run offs this year and last and even the year before almost half of the feild where rotary powered. there are alot of gt3 cars running and winning alot with rotary, there are a good number of rotary running in gt2 aswell and winning. hell there is even a hand full running in gt1 and last year a rotary one the national at sebring.
that is not to mention the rolex series where speedsource killed it the past few years with the 3 rotor rx8 and in st there doing quiet well as well as in world challenge ect ect ect..............
also on a reginal scale ITS is dominated by second gen rx7s
the problem is not a power issue or a noise issue its a fuel consumpiton issue as we all know that these little air pumps drink alot of freaking fuel to make power. and another issue is rotary powered vehicals are only in one car wich was fazed out for a few years untill recently with the rx8 wich took alot of rule making to happen to allow the car to compeat.
every time i open a GCR i am amazed in how much weight a rotary powered road race car in any given class has to weigh as compaired to its comp.
And where did all the factory cars go and WHY??? Because they couldn't make the power and meet the noise levels of the classes with p-ports and be competitive.. Cover your ears all you want guy but its a fact.
Taking a mustang dynos ouput as gospel compared to what OEM's use is like telling me your AEM is on par with a Horiba... I don't even wholy trust what comes off of my own dyno sometimes as real power figure.. for instance, look how many people post 500+ rwhp dyno charts with single walbro pumps, yet on my dyno, not one car with a single walbro has ever had enough fuel to get past 380-400 rwhp.. Is every pump I get bad or is my dyno reading a lot less than others?
You say you can make big power with a 6port right? I'll bet its a **** load quieter than a p-port at the same power level, or at the same noise level, the 6 port will make more power than the p-port. Thats the whole deal behind the renesis, low overlap, low noise, cleaner motor, more power than previous sideport designs.
If my track ever gets noise limits, the p-port will become a door stop..
As for building it, use new style rotors with the reliefs pre-cut, if use steel seals you need to clearance them in the slots forextra gas clearance. Use a turbo oil pump run FD oil pressure regulator, baffle plate is a must.
Even if your e-shaft is new, check the runout, the newest e-shaft I had was the worst, I went through a box of them and found one that was dead straight. I have never had a need for aftermarket balancing, I use the j-spec way of making sure its balanced well enough to live, but if you have access to it, and you are using mix and match parts, probably a good plan.
As for housings, I dunno, I make my own, so I can't comment on the quality of whats out there.
