Big triples, still out there?

[SnoPro1000]

If torque is what gets you up to the top of the hill?
Where have they all went?
Why not turbo a triple? Could you imagine?
Maybe stick a 1000 triple in a M-series?
Lets see some pictures of your triple, Cat, Poo, Doo, Yami

Sleds to tight

Tripples are great at making power but to fit them into a new chassis is a major undertaking with lots of custom fab work. brad(1200psi) has done a lot of them putting watercraft based polaris motors into iqr chassis, that is the most comman tripple in a new style chassis setup you will find. Large tripples with nitrous set up properly can and will run with turbos drag racing so they still have a place for someone who wants to do the work

I ride with a couple triples, nothing runs/sounds like a triple!

Buddy had a 97' Mountian Max with a Bender 800 kit, ran awesome!
Other has a 98' Thunder Cat, PSI pipes, some motor work, runs very hard!
New one has a 98' SRX with a UB topend and Aaen pipes, again, very good running sled!

Yeah, if I had the money, my zx would be getting a big rotax triple, maybe next year....

Tripples make good hp and rev quick. But THEY LACK TORQUE! Just like the cummins guys argue, their 6cyls make better torque than the v8 powerstrokes or duramaxes. The bigger the piston the bigger the torque generally speaking. Therefore, an 800 twin has alot more torque and wider powerband than an 800 tripple does. That said, I still miss the sound and feel of my ultra bigbore to 800

 

[SnoPro1000]

your right the sounds is out of this world, you can not mistake a triple. and the power is completely different then the twins, the twins pull hard on the take off but the mid and the higher RPMS i find that the triples will out pull a twin just my experience.

 

[NROBISON]

I rode twins for alot of years, but once you go tripple you cant go back, the sound and the pull are somethin you will never get from a twin. The bigger the tripple the meaner they are.

So make a triple that runs bigger pistons than your twin does

1500 KK w/ T-cat hood/bellypan. It is the most fun sled I have ever ridden.

Two 900 twin bottom ends welded together, running M1000 pistons.

Yeah, I know, I need a real video camera...

What he said^^^ LOL. Love the sound, love the pull once it gets too 7500 rpm, the thing just rips your arms off. Doesn't have the really wide powerband like a twin, which makes them harder to clutch and jet (always gotta stay in the sweet spot). I still love my big triple though (sled on the right).

Who makes your triples??? Set up the engine right and get your clutching dialed, you'll feel the launch!!

The pull at takeoff on a big twin comes more from the long stroke than the big piston.

Another thing to consider is reliability when you want BIG power. Easier to get 200Hp out of a triple 1000 compared to a twin because of more cylinder wall to put ports in. More piston ring to transfer heat away from the piston and a smaller piston with a shorter heat-path to cool the thing.

The one thing I DO feel on my triple tho is the resistance to turning, meaning throwing the sled on its side during acceleration. The long crank acts like a stabilizer.

Sled is started with empty carbs, hence the pulling to get it to start.

anyone looking for a 1110 twin rotary in a ck3 chassis with a 80 shot of nitrous we have one that we would part with. has been strictly used for drag racing the last few years but is a very strong mountain sled. chassis has a full drop and roll with a 2" 151. about 250 hp natrual. climbs anything just doesnt come down real nice.

I build my motors. Don't get me wrong, it hauls a$$, its just a different powerband than my twin. My twin is far more linear in peak power delivery (the nature of a twin), the triple peaks and falls off faster but comes on stronger.

Triple pipes and a new outlet moved the peak power higher and it comes on a lot faster at the 7500 rpm mark now. It still pulls hard from the bottom, just comes on a lot harder at 7500. Its predictable so you can ride it, and it doesn't "hit" hard (its pretty linear to about 8300 rpm), but without looking at the tach you can tell when you are at 7500. That's why I love it!

1200 watercraft polaris based tripple, the sled poo should have built from factory!

Pulls hard, dont know about the whole peaky powerband thing??? Just get it anywhere from 8-8500 rpm and they just flat out go!

I beg to differ on this one. 800 triple will consistantly out perform an 800 twin on the hill all day long day in and day out. 800 twin builds 100 ft lbs roughly and an equally prepped 809 rotax can do 115. Which one has more torque? The twin can build a max of 155-160 real world hp and the triple can do as much as 205. I'd rather have the triple any day.
Move up to 1200's. Use the two motors I have ran for example. One was a full mod Crank Shop 1140 reed twin. Current is a 1200 watercraft, no porting and 91 octane ready. Both with v-force reeds and crankshop pipes. 1140 made 206hp@8000-8100. 1200 watercraft made 204@8150. The triple makes the exact same power at almost identical rpm as the twin, yet the tripple is in essentially stock form, running less compression than the stock 800 twin who's basic design it is replicated after. Big piston in that twin sure made up a lot of difference eh? And thats why my tripple isn't dead, nor will it be any time soon. Oh yeah, wanna see wide powerband? My tripple makes the same torque from 7800rpm up to 8200rpm. Wonder if the big twin can compare to that?


Edit: MattyMac, kinda funny we were typing the same thing at the same time!

I'm seriously thinking of building a ultra based triple this summer looking at getting a 1030 kit from UBR what are any of your thoughts on this motor ?
What kind of hp can i expect ? I will probably go the pump gas with porting from Doug Ruth. What kind of hp could you get out of a 680 ultra motor with porting and the usual engine mods ?

You'll get 220Hp if you find the right guy, reliable on pump gas.

Stay away from the -96 bottom ends and you'll be fine. Pour gas and go engine when setup good.

Kudos to you for getting there and makin your own

Respect that. Massaged a few ports but keepin my hands of the big stuff, know my limits. Buy from the best instead

Ride on.

This is nice to see, there is still some ppl that rather the triples, Don't let em die out because they are "old iron" may be out but will most likely be right beside you on the top of the mountain!

I believe mine is a 97 but what was wrong with the 96 ?

freak58trio, if you're serious about putting a triple together i was checking out the ftx/fastracks website and under their clearance items they have a new unionbay xcr1030 kit with a lot of good parts forsale with a good price tag attached to it. It needs some finishing but for what you get it's an excellent starting point, if it's still available. I'd be checking it out if i wasn't stepping up already to a Price rotax build! Higgins.

That's awesome and that is what the big triple is all about!! I would love to see a shot of your dyno graph or chart #'s if you have one - making good peak torque for 400 rpm is outstanding, definitely a strong contender for why you probably have a large powerband - you're probably in the top 20% of torque production for almost double that rpm band.

Long live the triple!
