201er Posted June 1, 2013 Report Share Posted June 1, 2013 Since you guys have been bugging me for a new video I quickly through this one together on my last xcountry flight from Linden to Michigan and back in one day. Some IFR flying and a tour of some of the gadgets. 4 Quote Link to comment Share on other sites More sharing options...
Bob_Belville Posted June 1, 2013 Report Share Posted June 1, 2013 Nice! Do your front cyls typically run 50 cooler than the rear? (I assume 1 & 2 are the front.) Quote Link to comment Share on other sites More sharing options...
201er Posted June 2, 2013 Author Report Share Posted June 2, 2013 Yeah. At least that much. It's not uncommon for the fronts to be under 290 and the back over 360. I wonder if people ever "rotate" cylinders like they do with car tires to even the wear? Quote Link to comment Share on other sites More sharing options...
Bob_Belville Posted June 2, 2013 Report Share Posted June 2, 2013 Not sure about a J... I messed with the baffle seals on my E and went from 40 diff to about 20. Quote Link to comment Share on other sites More sharing options...
201er Posted June 2, 2013 Author Report Share Posted June 2, 2013 Well my front's are running way cooler than yours. Back cylinders are the same. Baffling seems good on the back cylinders and keeps their temp reasonable. Not sure why the front gets to be so much cooler though. What I'm trying to say is that I don't think that the back ones are getting insufficient cooling but rather that the front are getting proportionately too much. Anyhow, bird is in for annual at MSC, so I'll see what he thinks about it. Quote Link to comment Share on other sites More sharing options...
Bob_Belville Posted June 2, 2013 Report Share Posted June 2, 2013 I'll be interested. I think Jetdriver's 201 are pretty close front to rear. Quote Link to comment Share on other sites More sharing options...
201er Posted June 2, 2013 Author Report Share Posted June 2, 2013 I think he got some kind of mod to block some air from the front to allow them to be hotter to even things out. Byron, can you explain that more? Quote Link to comment Share on other sites More sharing options...
Marauder Posted June 2, 2013 Report Share Posted June 2, 2013 My guess is that he has air dams. Little pieces of metal blocking the front if the front cylinders. Quote Link to comment Share on other sites More sharing options...
Oscar Avalle Posted June 2, 2013 Report Share Posted June 2, 2013 Really nice video. It was nice to compare your JPI data with mine. I see that your #3 runs also hot. It seems to me that this is just a design issue. Quote Link to comment Share on other sites More sharing options...
