dcrogers11 Posted May 4, 2019 Report Posted May 4, 2019 (edited) I had purchased my Lasar cowl enclosure some years ago and never got around to it and now have some time on my hands to do the install. For the life of me though, I can't find the instructions that came with it. I can call Lasar on Monday, but wondering if anyone had done a short video or picture sequence of their installation and if there were any lessons learned from your experience. Thanks, Don Edited May 4, 2019 by dcrogers11 Quote
clh Posted May 4, 2019 Report Posted May 4, 2019 Just call LASAR. The instructions are very clear. There are several options of installing. Each takes a different amount of time. I didn't do a video, but install took a bit longer than that listed on their website. I did the more complex installation option. It came out good. Improved cooling, not sure about any speed gains..... Quote
Andy95W Posted May 5, 2019 Report Posted May 5, 2019 +1 to just call LASAR. I also did the more complex installation where the cowl enclosure is sandwiched between the cowling skin and the structure. It really looks a lot better than the original or the other options, but it does take a good bit more time to install. Quote

I didn’t do this installation, but as Andy pointed out it looks like it can be installed at least two different ways. Mine was this way when I bought it. Quote
brad Posted May 8, 2019 Report Posted May 8, 2019 Use the more complex "sandwich" installation. Did on my 75 F. Great mod. Quote
steingar Posted May 8, 2019 Report Posted May 8, 2019 A couple of my pals did this mod, they really like it. I'll do it when I have the coin. 1 Quote
mooniacX Posted May 8, 2019 Report Posted May 8, 2019 My plane uses flush screws installed by previous owner. It makes it much easier to access the alternator and starter. It looks pretty good, but not a nice as the sandwich installation. 1 Quote

I really like the idea of access, hate pulling the bottom cowl to get at the starter and alternator. 1 Quote
TheTurtle Posted May 9, 2019 Report Posted May 9, 2019 in for replies. I have it too but never installed. Quote

Its not the best, as we were putting in a new alternator and not all the screws were put back in. Sorry for the sideways shot.. 1 Quote
RLCarter Posted May 10, 2019 Report Posted May 10, 2019 LASAR claims better cooling, less cabin noise and a 5 mph increase.... has anyone seen one or more of these claims? It does look better than stock and it’s a fairly expensive mod, depending on the way it’s installed. I’ve considered installing it as an aesthetic mod and be happy if any of the other benefits came true Quote
clh Posted May 10, 2019 Report Posted May 10, 2019 Saw better cooling. Not sure about speed increase... maybe a knot or two. 2 Quote

That bottom cowl is such a PITA to drop on the vintage birds. But mine came with it installed - it certainly looks nicer. If it helped cooling, I'd hate to imagine what my cooling was like before it was installed...it's still pretty lousy now. 1 Quote

mooniacX Posted May 17, 2019 Report Posted May 17, 2019 Yes, with the flush screws it is removable in about 30 seconds. 1 Quote
N6018Q Posted May 24, 2019 Report Posted May 24, 2019 I don’t have cooling issues and am skeptical of the speed claims but am interested to know if anyone noticed a noise decrease after installation. Quote
carusoam Posted May 24, 2019 Report Posted May 24, 2019 Measuring a noise decrease... One would have to first measure the current noise level... Its pretty high to begin with... We have three sources of noise... prop tips... nearing the speed of sound... Exhaust noise...a muffler that doesn’t really muffle... Air frame sound... We are Not really noticeable coming in in stealth mode...aka dead stick... Might want to look into that claim... there must be more detail to it? Having the prop made from composite materials can also change the sound quite a bit, for people on the outside... Europe has a few laws about noise reduction, MT has put some effort in for that... For comparison, The O has a nicely enclosed cowl... great CHT cooling, with no cowl flaps at all... And it is pretty quiet inside for having a reciprocating 9 liter engine up front... The sabremech cowl took many steps to smoothing airflow inside the cowl and outside the cowl as well... Doing away with the square-ish dog house is a brilliant airflow design step.... PP thoughts only, not a sound... hmmmmm... not a noise engineer... Best regards, -a- Quote
dcrogers11 Posted May 28, 2019 Author Report Posted May 28, 2019 I've completed the installation and opted for the external option as I wasn't wanting to tear into the lower cowling. After the storms pass, I should be able to try it out and see if there is any noticeable improvement on cooling and speed. I've not had a cooling issue, but certainly should help on the extremely hot Texas days coming up. Don 4 Quote
0TreeLemur Posted May 29, 2019 Report Posted May 29, 2019 @dcrogers11 what a ridiculously fantastic hangar !!! That is what my vision of Heaven looks like! 2 Quote
tomgo2 Posted June 1, 2019 Report Posted June 1, 2019 Anyone have an airplane with the SWTA cowling? Any PIREPS on them? Quote
Sabremech Posted June 1, 2019 Report Posted June 1, 2019 A friend of mine has one on his C model. It looks nice and was a well thought out STC. The only thing he doesn’t like about it is the lower cowling fit by the spinner. 2 Quote
Sabremech Posted June 2, 2019 Report Posted June 2, 2019 (edited) Having done a cowling mod very similar to the SWTA cowling on mine and 3 other aircraft, it’s very labor intensive. That and the fact that it only will work on certain year models is the reason I switched to doing a full new cowling. My new cowling will fit the early model Mooney’s all the way up to and including the J models. It will be much less labor cost to install. I was able to get some valuable data from the 4 airplanes I modified and put that into my new cowling. David Edited June 2, 2019 by Sabremech 2 2 Quote
