BIG IRON

[Deano670]

Have you ever been to a dyno session with 2 sets of identical pipes, one with ceramic and one set without????

 

[glengine]

Not yet.. But i will be this summer.. Why?? Have you???

Yeah more than once. You'd be suprised at what the results are!!!!

 

[glengine]

Oh yah.. On what motor?? What was the differences??

 

[Deano670]

Did you know that a TWO stroke uses the exhaust to SUPERCHARGE the engine

 

[glengine]

Well actually what they do is scavange out of the pipe to increase air fuel charge in the cylinder...This also helps to expel the other exhaust out of the pipe at the same time.. That is why the pipes are shaped the way that they are for harmonics and pulses of the motor... The shape of the cones in a pipe make a big diffference as well as you can utilize different shapes and lengths of pipes for different applications.. Ex. drag racing compared to mountain riding... So what was the motor that you did these dyno runs on???

ANY TWO STROKE. You'll see when you go for YOUR dyno session. Who's dyno are you going to use and what engine are you going to dyno.

P.S a MOTOR is a piece of electrical equiptment. It uses a coil of wire and magnets. FYI. ENGINE = INTERNAL COMBUSTION= AIR AND FUEL

 

[glengine]

Yah i wil.. But what i find strange is the fact that you never really give a straight answer when someone asks you a question.. Like what motor did you do the dyno runs on with different pipes???

Dyno sessions are useless to determine the effectiveness of any pipe since the atmosphere is controlled externally with a thermostat and a fan. Putting pipes on the dyno is only useful in their development and finding the most power, how they perform overall in the field is the only way to evaluate their real world usefulness. You guys can throw dyno sheets at one another all day, doesn't mean a thing when there is a fan blowing air on the motor and pipes in the dyno room during the testing. Pipes that are dyno'd at a consistent 20 degrees C in a dyno room under controlled conditions and how they perform in the field when covered in snow at 40 mph from -15 degrees to +10 degrees and from 2000-9000 ft in the mountains (all in a day) is apples to oranges. Same reason I run jaws pipes on my sled, they actually deliver real world power, not dyno room #'s. Didn't mean to start a weiner measuring contest here....

Glengine, to answer your question, first off, the T1000 sled isn't mine, owned by a buddy in southeast BC, I run something else....but no, I don't believe in ceramic coating or any coating for that matter and the simple reason is this...was the pipe coated when it was developed on the dyno? No, it couldn't be, therefore, it made the most power when it was uncoated and to try and maintain that, I will never coat any pipes (IMO, best to try and simulate the conditions on which the pipe was developed to make the most power). Also, I do find that they hold the heat better inside (be it good or bad), which pushes the power curve up the RPM band. The higher the RPM's, the less efficient a snowmobile clutch is, therefore keeping the peak power lower in the RPM band is key to me at least. I run a mountain sled where I need the most power down low, my sled is clutched for 7900 rpm. If I was running a drag sled that ran at 9600 rpm, I would probably have Neil make me a set of pipes for 9500rpm and then get them coated yes. I will admit that coated pipes (especially nickel plated) look very nice and clean up the engine bay were nicely, that being said, trailer queens should stay on the trailer IMO

Well interetsing subject !!!!!! A motor is just an air pump , Air fuel in, burn it and exhaust out, the more in .the more out .... As to a ceramic coated pipe ,done lots with NPP and you can get 2 different numbers on the dyno from a cold pipe to a hot pipe and ceramic coating keeps the heat in the pipe and usually makes more power but , there are a lot more in the equation than that from center length to restriction size and lots more ......

You will really like the 860 kit.. Which kit are you going to do?? The Rk tek??

I haven't really had alot of time to do my homework yet on the kit I'm going to use but When they time comes I'm hoping to talk to Deano about it, he should be able to steer me in the right direction.

NO a MOTOR is not an air pump. A ENGINE is an AIRPUMP(compressor) A motor is the electrical unit that turns the mirrors on your fancy pickup. And yes you are very correct in saying there is alot more to making power with pipes than what they are coated with. HOWEVER if the pipe is coated and gets to HOT it burns the AIR/Fuel mixture that is sent into the header( first 3-4") of the pipe which is then designed to supercharge the engine. If that mixture is BURNED the engine gets to suck in a nice breath of CARBON MONOXIDE which then chokes the engine.

My two cents

i am going M1000 turbo next year.

Don"t you mean Apex turbo????? C'mon buddy I need the sale!

 

[mtndoctor]

f900 field tested, speedwerx single coated then non coated.

 

[NosRX1]

Finally going to throw a turbo on the RX1, liven it up a bit.

 

[Deano670]

f900 field tested, speedwerx single coated then non coated.

What were the results if I may ask, whether they be good or bad for me
