Can am 900 Ace turbo....

[Tracker]

One of the first to do it with the 1200 was Greg Bennett, his first trip to the dyno he was pushing 430 HP with back in 09, using a 66 Aerocharger at just 22 lbs of boost way back in 09 with some antique fuel delivery stuff and keeping the RPM's below 8500 on a stock unopened 1200 engine. That was back before he started using better components and raising the RPM up! He frequently pushed it over 540 HP on that stock engine!

I have been involved with a CAT and a YAMI this same way...and I can tell you this....they were both NO WAY STOCK AT ALL....the engines had the cranks welded and blue printed and balanced...and titanium rods and all sorts of beefier insides...and even those were blowing on the dyno...get a new motor and change the boost...and the YAMI needed crank welded and stuff WAY BEFORE the CAT needed anything outta stock...and out west...all the guys I know running YAMI had to add at the very least about 11,000 grand to theirs sleds just to keep up with a cat turbo...stock....ya....sure

Not sure what u are trying to say, i mentioned the yami engine wont take the boost like the cat and doo.

Here's bennetts orginal run on the 1200....

So you guys are pushing those numbers with stock rods and Pistons.....


Give me a break....

Believe what u want but theres lots of guys running or have ran them way up. The.doo is strong internally from factory...

Here is a good post...from a known racer mike knapp who has ran all brands...

Well, its been done many times on the dyno by various individuals. It's a beast of an engine for strength with all stock internals. Just crank the boost up with a big turbo, proper fuel delivery and feed the octane to it and it will perform run after run there if you keep deto at bay. Best stock four-stroke ever built for strength! Not a stretch whatsoever, it's a known commodity. Not too many utilize stock turbo engines anymore as it takes 700-750+ HP now to compete with the big outlaw race sleds. So they all get into the engines now with HD rods, pistons and aftermarket parts and pieces, but back in the day many tried the big boost on stock engines till they found the breaking point with the weaker internal parts.




A couple Yamaha RX1 engines have been known to do 400-440 HP, but Its a push and won't do it for too many runs with rather wimpy rods before they ventilate the block.



heres a thread from another 500+hp run on a STOCK 1200....

It was a big reason why many used to think doo was going to bring a 1200 turbo from factory, the engine is way overbuilt!

Nothing wrong with 1200 in stock form doo just needs to punch up 1200 or Ace in stock form for those who want more hp without going 850. Seems to me doo could doo it easy and prolly will just needs to be sooner than later. I know you recomend add ons to get there but many buy stock trail sleds don't want to mess around with after market engine mods.

No engine mods needed to get them to really run good for what they are. The 16s were better than previous years as the ecm allows more RPMs, but with the cudney clutch and header this sled performs even better, all piece of cake bolt ons that dont effect warranty.

11-1 compression and 22lbs of boost...... Yeah ok....


I've been around engines a long time. Anything from lawnmowers to my own race cars. My riding bud has 2 turbo sleds currently. A 400+hp Nytro and a poo 800 RMK.

I've been around long enough to know not to believe everything that's on the Internet. And I've been around long enough to know what's what when building an engine.

Anybody can put up good dyno numbers, for one run..... Called a dyno queen....

Yea they mentioned multiple runs..but whatever, believe what you want, those in the game know the truth about the 1200, those that aren't think they know.

I will just leave 1/2 hour before the guys with the 500 hp sleds. I will still beat them to the next trail stop 30 miles away.

the don't worry they aren't.....stock....they are not stock....I did not say any of the above....wrong post quote...and your 400+....is it stock or not? that is the question...focus man....focus

No I was agreeing with you. It's all good.

The Nytro with 400+ has rods, pistons, head studs, and injectors. It's a mtn sled, and has 1800 mtn miles on this setup. Has not been apart since build. Above 30lbs boost the Nytro engine needs billet cylinders because the stock ones oval out.

 

[groomerdriver]

Yeah, that will happen....keep talking! We just Indy to free up some time so someone can wave the Poo pompoms too...

Now that rite chair is funny....I don't care whatcha say!

next time I see mike I will be sure to ask if he was running a stock bottom end pulling 750hp . I have seen a lot of his stuff opened up and none has just a turbo slapped on not even close not even stuff built for other guys$$

I still have a set of f7 jugs he did works of art.
other thing to remember is there is a huge diff doing a dyno run and then putting that same motor under the real stresses of the load of hard launches blown belts track slip and grip . real world not happening .

Mike never did 750 on stock bottom end, where do u get that? He said not many are running stock internal anymore because you need 750 to compete nowadays, which requires mods to internal of any engine


He said many guys doing 500hp on stock 1200 and said it is the strongest 4 stroke snowmobile engine ever built, please ask him that.

Im not claiming if you put 500hp to a stock 1200 engine you wont need new clutches/driveshaft/chain/gears etc.. but the internals of the engine can take it.

And I'm not saying it isn't the strongest sled engine ever. But I find it hard to believe it can live in riding conditions with 22lbs of boost on 11-1 CR. It must be one heavy a$$ engine. That's a lot of force on cast rods and stock head bolts.

Unfortunately youd be wrong. They are/doo. Not just one guy or one dyno either. The guy that did 507 is a grass dragger and that sled made many passes on an unopened engine.

A good bud of mine has had a turbo 1200 since 2010 and put thousands of miles on it running 18-20 lbs of boost on unopened engine. When he races someone fast he turns it up to make a pass. Never been on dyno but she is no doubt running over 400hp...and this is a trail sled. Once again the engine is not been opened. Believe wht u want tho.

Your bud must have fun finding race fuel on the trails.....

I supposed you're going tell me he runs 87 octane in it too......lol
18-20 lbs at low elevations with 11-1 CR? Your gonna need C16 to keep that engine alive. SBYL

Pre-mixs with linq gas caddy full of race fuel.

With boost down premium fuel is no problem.

Any more questions...LOL
