turbo maintenance
2014doo:
after reading some of these posts, i keep having flashbacks of nitrous meltdowns and our old saying of "bring two break two" regarding each person bringing multiple sleds for when the inevitable occurs. lots of broken parts, tons of down time, wrenching in the parking lot, and finally coming to the conclusion that that making a sled significantly lighter cost about as much as horsepower but was much cheaper in the long run.
here is my take on any 2 stoke turbo kit that is advertised as such. for an upgrade that costs $5-7K or more, it better be pull and go or damn close to it. anything with a engine can be tempermental; plenty of stories of stockers acting squirrely but if day to day, someone isn't sure if their turbo 2 stroke is going to run at least reasonably well, imho it's a mechanical problem, not a tuning problem. when the two strokes went efi, combined with det sensors, it was game on. "tuning " a turbo, assuming you know how fueling and afr's or egt's work, became as easy as pushing buttons and reading the numbers. the only "tuners" that i see get into trouble, mechanical failures aside, are the guys who get greedy; ie if 6lbs is good, 12lbs will be great. i always assumed the pump gas turbo came to the mountain segment to reclaim the power that gets lost in elevation. if that's where you want to be, there should be no additional wear and tear on your engine, or complete sled for that matter, than it would experience at sea level.
to be fair, we ride from 9-12k feet above sea level and while power robbing, this difference in altitude is relatively minor and somewhat forgiving. that being said, if some of you guys are seriously d*cking around with your turbo setups on a regular basis, i feel for you. you get in this sport to ride and wrenching ain't riding. 2014doo my advice to you is decide what boost you want to run, buy a kit that supports that level, clutch for it, fuel for it, and ride it (btw this putting guys on blast who want to run less octane, as long they are being mindful of the parameters that need to be paying attention to, why not? running 110 for sport during the winter in an engine that will not detonate on 104 on a hot summer day is a waste of money and performance). routine maintenance shouldn't differ from a stocker but the higher the boost, the more wear and tear on certain items, inside and out. no way around that.
i hope you can hook up with some cats that are running the kit(s) you have an interest in and they can give it to you straight. if you're ever in these parts, let us know. we may be riding through the summer if it keeps snowing.....
