Alex,
You have been firing a lot of questions at this group and we are happy to
hear about your interest in this hobby/sport.
Please don't get discouraged if you don't receive responses right away.
This is one of those weekends that a lot of guys are off racing or doing
the family thing. Not that many guys have the exact same buggy as you,
so it might take some time to get real good advise.
But here is mine:
Skip the boost bottle, you will never notice any improvement.
Many articles have been written about their use and I cant recall
one that found any increase in performance.
Two speed is a good upgrade, first gear is a little lower than stock.
This gives you much quicker acceleration. Second gear is higher
than stock and gives you a higher top speed. Good choice!
Vented disk brake is also good. It wont make the buggy any faster,
but it can help improve stopping and lessen brake fade.
I don't know if there are any pipes out there that are any better than
the stock Ofna pipe. The stock pipe is pretty damn good. If you
don't get any advise here, you may try asking around at the track or
hobby shop and see if anyone there has found a better one.
Most importantly, make sure you break in the engine properly.
This can make the biggest difference in performance of the engine
over the life of the engine.
I hope this helps you make a good decision.
John
