procharger Posted July 6, 2013 Report Posted July 6, 2013 Is it ok to use K&N air filter on ctsw 100 horse rotax engine ??
sandpiper Posted July 6, 2013 Report Posted July 6, 2013 Yes. Many of us do. Mine has been in 3 years.
procharger Posted July 6, 2013 Author Report Posted July 6, 2013 ok thanks I am new to this sight where do I find LOA ??
mocfly Posted July 29, 2013 Report Posted July 29, 2013 What is the part number Would you believe not one vendor has either a 4x4 tube or a filter.
FlyingMonkey Posted July 30, 2013 Report Posted July 30, 2013 Any power advantage? If so I will order one today if somebody can give a part number.
sandpiper Posted July 30, 2013 Report Posted July 30, 2013 I'm sure there is a power advantage but you won't be able to notice it without some sophisticated equipment. The advantage for me is I will never need to buy another filter.
FastEddieB Posted July 30, 2013 Report Posted July 30, 2013 One time I tried a K&N in an airhead BMW. Went out and did back to back timed roll-ons. Zero measurable difference. Unless the stock filter setup is especially lousy, I would not expect any noticable performance gain. BTW, my plane came with a JR Filter that seems very similar in concept to the K&N. Just wash and lube it annually and it's good to go. Stock photo:
sandpiper Posted July 30, 2013 Report Posted July 30, 2013 In my 1991 Dodge Stealth Turbo. there was (is) an outfit in Texas that dyno'd some performance enhancements they sold. Their induction kit, which included the K&N, was good for 12 HP on my 300HP engine. But that was more than just a filter. I remember they said the filter alone was good for 6 HP. So, using a direct relationship of 6HP/300HP = xHP/100HP (which probably doesn't apply here) you get a 2 HP increase for the CT. Since we never turn the 5800 RPM needed to generate 100 HP, the increase is even less. So, convert to K&N but don't do it for power.
mocfly Posted July 30, 2013 Report Posted July 30, 2013 Roger, What do you think about having either individual filters or the recommended metal cross tube assembly?
Gmoore7 Posted July 30, 2013 Report Posted July 30, 2013 Roger put me on to K&N a few months ago. They are fairly easy to install and I saw a little lower temps.
FlyingMonkey Posted July 30, 2013 Report Posted July 30, 2013 Cool, sounds like something I'll do at my next annual, but not run out to do before that.
GlennM Posted July 31, 2013 Report Posted July 31, 2013 I am a little wary of K&Ns. Maybe they are OK for airplanes since they are not on the ground very long, but I have a friend who was a Ford master mechanic for a local car dealer and he said the K&Ns don't seem to filter very well. He said he saw many examples where the turbos on diesel pickups failed with K&N filters in place. It appeared the compressor wheel vanes were eroded by particles passing through the filter, which thinned the vanes to failure. This is all anecdotal, but it was based on his observations at the dealership. He recommended not to buy a vehicle that had K&N filters. Ok, my flame suit is on...
FastEddieB Posted July 31, 2013 Report Posted July 31, 2013 Glenn, That's the general position of the BMW motorcycle owners. You get more flow at the expense of larger particles passing through, it would seem. As a control, when I compared the K&N with the factory pleated paper element on my R100GS, I also tried a run sans filter. Guess what? No measurable difference. For the most part, factory specified filters flow air just fine. If significant hp gains could be had so simply and easily with no downside, don't you think they'd do it?
sandpiper Posted July 31, 2013 Report Posted July 31, 2013 Wrong? I represent that! :blink: Just like I have never been lost. There were just a few times I didn't know where I was. That's not true either. I knew I was in AK.
