I would rather go with Novarossi but there is one thing that confuses me.
I am looking at the flash .21 3 tuned and the 5 tuned. What is the difference between 3 port and 5 port and why should I go for 5 port? Their power output seems the same.
Will I need a fuel filter? What about exhausts? And finally, what air filter should i get? Do i need the ones with the silencer box?
Hahaha, Im sure some people are going to (Sigh) over this!
OK. For legal racing, go the 3 port - that is the maximum allowed in racing. 5 port motors have more power up top than those with 3, but also use up more fuel on the downside.
As for a fuel filter, it's better to be safe than sorry!
Exhaust: The 2660 is an excellent - and the most powerful (I believe) - pipe to run it with, combined with a short conical header and also the most fuel hungry. Not entirely sure on other pipes, but surely the 2630 pipe would be compatible as well as a variety of others, but the 2660 is what basically 9/10 of people run here anyway (plus it sounds awesome too
With the airfilter and the INS box, I would use the INS box. It doesn't really do much to performance, and it also keep the outside of the filter cleaner between runs compared to running without one.
There are a few people that make them - RB, Novarossi, Xceed, Mugen and a few others. Xceed is the lightest from what Ive heard, but you want a good quality filter.
On a side-note, why don't you wait for the new Novarossi Line-up for the next season and see if they have something better than the current Flash .12? I remember seeing somebody saying a new Flash .12 will be more powerful and more fuel efficient (or maybe a Flash .21 Special)
