My point is they offer a Stc that some would like. That's all.If lycon offers it I'd get it from them. I'm just purchasing the Stc so hopefully there won't be any problems.

Are their issues heat related? If not what are the problems plaguing their power plants?

STCs are advertised however not all. Ly Con roller cam Stc isn't advertised. You need a newer style case. I found one for my E, it had some damage repaired it and also port flowed my jugs with powerflow. Only thing missing is hi comp pistons. Can't have them in a A1A. Hoping to make some More than stock hp. For my J I'm going to do all that with the firewall forward hi comp Stc. Really you just need to gap the rings correctly and do there special cylinder break in procedure not like stock break in and your golden.

Ly Con charges 250 per head for porting so 1000 plus tax if your in California. They will port any worthy jug new or used.

No need for luck. I know there are differences between and aircraft engine and a helicopter engine. However, they are fundamentally the same. The new firewall forward might have communication issues as they did a centralube cam for me and were difficult to contact. I figured they were in the back working. In this day and age who can always afford someone to answer their phone. They are still providing a service that otherwise would be unavailable. What ever shortcomings they might have I believe is overcome by the service they provide, and I'm not talking about bedside manner. I'm talking about giving us better STCs. Lycon runs hi comp pistons in there race motors with no or very little issue be it heat related. Lycon told me as long as I didnt use chrome cylinders Id be ok. They related a story to me about a guy who ran 10:1 pistons in an M20E A1A. There was someone at the fisdo that was going to field approve it for him. He had great success with them, he just bought a K before he got around to gerting it approved and put it back to stock. The moral of the story is if you want Hi Compression pistons in your Mooney there is a option and it works if done right. I wonder what a io360 would do with a roller cam, port flowed jugs, hi comp pistons and a powerflow? All STCs available to use certified aircraft owners. I believe that would blow the io390 out if the water for the dollar spent. Perhaps 240 hp in a four banger, could you imagine a certified M20J with that without all the weight of a Continental. We have the octane at the moment, I believe we should use it.

This Stc is just allowing us Hot Rodders or us Mooney owners to go faster. The Stc is a gift from God. How many of you truing out at 160 k have said in the back of your mind "Would be nice to go just a bit faster." This Stc is meant to squeeze 5 more k out of your A3B6 at altitude never mind more power on take off and climb.. There is no mp restriction on take off. I wanted it for my E though it is a A1A and wouldnt work because of the lack of a counter weighted crank. People run these pistons all the time in the experimental world and besides lycoming in there io360 helicopter engine. I doubt lycoming would install them in one of their helicopter engines if they felt they were an issue. I mean if they run flawless in their io360 helicopter engine then it might make sense that they should be able to work on a their fixed wing version. Im purchasing the Stc for my J and will post the performance increase once established. The new firewall forward went out of there way to offer us io360 owners who want it, more power and the option if we so choose. We all know the options us certified aircraft owners have.

Still for sale? Will that prop work with my io 360 E model?

I will post pics after I'm done. Waiting on the bulkhead at the moment for cowl placement.

And if so does anyone have a J bulkhead and or spinner for sale?

I'm in the middle of a firewall forward restoration on my 64 E. I'm doing the J cowl conversion. One question though is will my simitar spinner and bukkhead work with the J cowl? Or does the bulkhead come out farther?

Very interesting that aerostar could own the mooney corp for one year and do such a unique change to an already unique vertical stabilizer.

I am going to be replacing the old instrument panel and installing a more modern flat no tilt panel. Has anyone done this already and know what is involved? It seems pretty straight forward right, cut a new panel and just install it? But is there any structural add on s? Please any information on this would be very much appreciated.

I just ran across a picture of a strange looking mooney. Upon further examination it came out to be a aerostar mooney 201. What are these aircraft and where did they come from?

Thanks again everyone on all the great posts! I talked to Mark at Top Gun and he is all too willing to help me get this thing figured out. He seems very knowlegeable and he is in the process of doing some research for me from his own conversion. And I'll have some before and after pics real soon if this goes like I hope it will...

Jorge do you remember where the stc was from? I've been looking for such the thing and have been unable. And if you could find any old info you had on your install that would be a great help also. Thank you everyone for your posts they have been very helpful and I will post some pictures as things progress. If anyone has any idea where I can find the induction parts that would be Great.

I am installing a J cowl on my E and need some parts. The induction parts Cowl flap linkage and anything else someone might have that they are interested in selling from a J model I would so very appreciate any help in this matter Thanks

George you wouldn't happen to have the break down of parts and part numbers? I have the cowl with the cowl flaps but I know thats only part of the battle. Neat thing is Airforms.biz makes the complete baffling for 1200.00. I just need the cowl flap linkage and the induction parts. I think I'm going to get rid of the ram air induction. I hear that it doesn't do much with the J cowl. On my E I get about 1 full inch of manifold pressure when using the ram air induction at altitude. It really is a kick in the pants for my E. But again with the J cowl I hear barely a 1/4 inch of manifold pressure. A guy told me he was using the ram air induction and something got in through the ram air hole and he heard it going through his engine. What it was could only be speculated but that also could be a concern.

I was wondering if anyone had a detailed list of what was needed for the modification and or plans that someone may have who may have done this modification already that may help me with the FSDO? Thanks for bringing the mount issue to my attention. I was wondering if it was just a bolt on linkage modification or do I need to find a J model engine mount? I will also call lasar and see if they can offer any help.

I have an M20E and will be putting a J model cowl and front windshield on it. Does anyone have any suggestions as to how to get this done right? I have the J cowl with the cowl flaps. I need the Baffling and airbox along with all parts as it will be relocated along with the oil cooler. Has anyone already done this and perhaps had any real experiance? Maybe a link to a previous forum on this subject?
