Test flight - 1415 in climb until I got to 3000' MSL or so. Awesome RPM, over 3200. At 90kts was almost 3300, but the EGT went to 1430. Way better than before. I'm not done but on the right track I think.
Congrats! I'd have to get it approved by the war department but may be able to put you up at C77 if you need a stop. There may be others who would do the same. Even at 100kts it beats driving a uhaul.
A view of my flow straightener via inspection mirror. Test flight after work today.
I originally used pops for the flow straightener. Got to thinking it would be bad if a mandrel went through the engine. I drilled out the pops and installed solid rivets.
My super simple deflectors. Not much surface area is blocked due to filter radius, pleats, and a slight bend front & rear. The rivet tails in the pleats help keep alignment.
I read through this and I have a few thoughts/considerations: Good luck! Robert, 1) I've had two air filter configurations. One directly attached and one with the elbow. The only reason I swapped was because I didn't have the K&N RC-1980 safetied. It fell off and melted on the exhaust. It is no...
You need to get a good reading on the CHT. That's all the matters, really. If the CHT is in line with the others, and within the proper range, then there is likely nothing wrong with the cylinder, so it would be a sensor or display issue with the EGT. My CHTs have never been matched, or particularl...
When I did the cold air intake on the R2300 using a Rotec MKII carb, Rotec cautioned about elbos near the carb. There were none but but I did go ahead and make a flow straightener to dampen any intake air swirl. Perhaps something like this might be helpful. So here is my shot at it. I figure my fre...
I was wondering if the timing needs adjustment. I thought that I might be too lean, but from what you guys are saying, sounds like too rich. I'll continue to tune and will go to #2 needle if I can't get there. N153TD First Flight.png So you have the #2.5? I would really recommend the #2. My first c...
