Boosted Engine Reliability

[Veedy]

hey Veedy, do those guys get any parts or even pay to be in your movies?


4000 km on my Apex at 18lbs.
stock engine, no engine issues to date.

Hmm. that's a good idea ! do you want to pay me to be in my movies ? that way I might be able to at least break even in my costs !!!
I need sponshurs ( lol ) bad. The sponsors who are mentioned in my films are not actual paying sponsors ( in other words, no one has yet cut me a check ), camera equipment has run me in the tens of thousands, my editing station is worth a small fortune ( can you say second mortgage ?? ) and all the fuel , parts and my sled is out of pocket.
If I had some sponsors on board who could equip the guys with stuff such as clothing and gear, maybe some mod parts to advertise, that would make me and everyone happy. So far no one has stepped up, and I don't have the time to go begging. I just enjoy filming and riding with the boys, thats what I like best.
I spend all season riding and filming, then all spring and summer editing and producing, and then replication costs are also out of pocket, plus these movies don't just ship themselves.... there is a TON of work behind the scenes, I know most people appreciate it, and I get a kick out of people's reactions to the show. That's my rush.
Sorry, no paycheck here, and certainly no-one getting rich, but a whole bunch of guys having fun, that's the main thing.

ya, I know there's no money in sledding, anyway there will never be a shortage of guys willing to risk 40k sleds just for bragging rights, getting into a movie is a bonus.

maybe one day the general public will take notice of our sport, especially now that there is more than just 2stroke short tracks jumping in the movies.

what if someone made a real movie with a plot and actors etc, that was about sledding with lots of stunt riders doing climbs on turbo's. kinda like what the Fast and the Furious did for tuner cars or Cliff Hanger did for mountain climbers. now that would be sick.

The failure rate of a boosted engine depends on what is installed between the seat and the handlebars. I have customers going into their 5th boosted season on stock engines. I have guys running 18-20+ lbs with LC pistons or shims + rods and they're holding up just fine. I also have a dozen or so guys every year that write boost checks that their octane can't cash...

If your kit is installed properly, and the boost level is set appropriately for your conditions (& fuel available) there is no reason that you should not realize near-stock longevity out of your engine.

Most guys run into problems when the 'base' setting isn't enough for them anymore. These are strong mills, and they can handle quite a bit of boost on stock internals. Start detonating one though, and it gets really expensive, really quick.

I appreciate the replys, my setup is good. I am running the impulse setup with shim, and always run good race gas (sunoco) and will be around 15psi for the most part. So hopefully with a little luck the beer will be cold and smooth this spring.

I have bulk 100LL on tap what would the max boost I could run with head shim? I hate trail riding and the little I do is usualy putting around ungroomed stuff around here. I think it should be a hoot in an open field with two or three feet of fluff though.

The biggest difference, with turbo setups on bikes vs. sleds, is the intake charge temp. Bikes, being in the summer, see 80 degrees and up, and then, the systems have no, or a very small intercoolers. Sleds operate in the teens and 20's for temps, and have much bigger intercoolers. As an example, bikes with no intercooler could see 300 degree's air temp, sleds with a cooler, might be in the 60 to 100 degree range. And to make matters worse, the hotter charge temp, makes the turbo setup, less efficient, so there is a tendency to turn up the boost, further risking engine failure. Bottom line, enjoy your beer.

Here's the deal, I'm a flatlander looking into boost, most likely a SC. However I'm not interested in screwing up my engine reliability, I'm wondering what the failure rate of the boosted engines are. Can a guy set up the charger and just ride or is it a never ending tuning game. Oh yea, the machine is a Nytro XTX. Thanks for the help guys.

Just turbo and you will have no worries. That's the only way to go. Find the setup of your preference and you'll be good to go.
