Did I cover all the threads?

Did you have paddle LEDs installed .... Did little Timmy know?

Heavens forbid. How did I forget those notable threads?!

David, I think this question has been asked and answered but this thread is 14 pages and growing so I'll ask again.

My '66E has the LASAR mod relocating the oil cooler and adding a second landing light in its place. Will that cause any difficulty with the new cowl?

[Sabremech]

Hi Bob,

It will not be a problem. I will have a lower cowling piece that will not have the oil cooler cut out for those who have the oil cooler relocated. The second landing light hole will need to be cut out and the light installed as the original. I'm getting ready to have that lower piece made now so I have it included in the STC.

Thanks,

David

Hi David,

If I remember correctly.... I thought you had mention that you seen cooler. CHT  something like 30 degrees  

I was wondering if majority cooler temps  come from  cowl  redesign ?  or new Engine cylinder baffles or both or ???

Does your design replace the engine dog house baffling ?  Does the engine baffling  redesign to increase airflow  around the cylinders?

 

 Thanks,

James

Great!

Hi James,

I am seeing reduced CHT's. I did replace the old dog house with new baffling. It was necessary to get the air filter relocated to the left cylinder air inlet. I think the change in cooling is a result of both the new baffles, air inlet size and location of the inlets. 

Thanks.

I also have the Oil cooler relocation and am interested.  It includes a stiffening bracket for the baffles.  Will we be able to use only the front portion of your new baffling to maintain the stiffener for the oil cooler mount?  Also, will the ducting and baffling accommodate different starter and alternator/generator combinations.

I have the 66  and up C & G cowling mod pretty complete and can proceed to building the STC package and get that submitted. The 66 and up E & F models, I still have the baffling to work out and the adapter to the air filter to make. I'm hoping to find an E or F near me to take some measurements then I can get that package going. 

Maybe a silly question but do you mean 65 and up as the major modification in the E and C started with year model 65?

[Sabremech]

Hi flyntgr1,

If you already have non dog house style baffling like what I see on 67 and later models, then you would only need the front two cylinder and forward baffling for my mod. If you have the doghouse or other baffling, I'll be providing new baffling that you can install the hardware to mount your oil cooler if it has previously been relocated. There should be ample clearance for ducting to clear different starter and alternator or generator installations. I can post some pictures of the clearance on mine tonight to give you an idea of space available. 

Hi Drapo, 

From what I see, the 65 is unique and kind of a year in transition for the cowling. The 65 has a small bump in the top cowl near the spinner where the 66 and up don't. This bump extends past the factory split line for the forward cowling section that will cause me to make one specific for the 65. The Pre 65 is even more challenging as Mooney spot welded the cowling sections together. I haven't spent much time on the pre 65's yet other than acquire as much of a cowling as I can right now to look at ways to modify it without replacing the whole cowling. 

Thanks,

David

Thanks for the reply.  I am just as "unique" as the 65 even though I'm a 1957 model!

Dave,

I sure hope you have something for a 1963 M20C in the works, i would hate to be left out!!!! What you are doing is taking these antiques and bringing them into the 21st century. There still is nothing that compares in terms of cost and performance, for all of us CB.

I prefer Vintage.

[macosxuser]

I'm interested, but wondering what the advantage will be over a 201 cowling or the SWTA 201 style conversion? Obviously cheaper than Lopresti is a goal?

[Sabremech]

Hi macosxuser,

 The advantages will be that it's available for one when the STC is complete, easier to install than getting a field approval and finding 201 cowling parts, and substantially less expensive than the LoPresti. Hope this helps.

Sabre,

When are you going to have some performance data? This thing has been flying for a while and you must have an idea if not hard analysis.

PPPPleaseeeeee!!!

I just pulled this off Coy Jacob's Mooney mart page( are they closed?). I was amazed at the price, expensive ,maybe cause i'm just poor.

Change Your Pre-201 Into A M20J/MSE (FWF) At A Fraction Of Trading Up

This Factory OEM; (Original Equipment Mfg.) Cowl Mod completely changes your Pre-201 Firewall Forward (FWF) into a Mooney Factory 205/201 clone! Increase cruise 5-6 MPH & lower Oil & Cyl. temps!

In order to insure resale, ease of maintenance, and acceptance for years to come, we use an extensive list of Genuine Mooney (OEM) Factory Parts and duplicate the factory installation exactly.

Don't be confused by non-factory (non-OEM) or PMA (homemade) look-alike Mods!

Mechanics and owners alike love this mod because of the increased accessibility to the vital engine components. Included are: new (or pre-owned) upper and lower Mooney Factory M20J Cowls and cowl flaps, new air box and filter assay., spinner and bulkhead, all new engine baffling, and relocating the oil cooler and landing light assay's. etc. In general, all your old pre-M20J parts FWF which are subject to vibratory wear and fatigue are replaced. This mod is not an expense, but an investment! And, it is one of the main mods to turn a pre-201 into a M20J and it's resale value is documented in the BLUEBOOK!

Notes: Besides this being one of the most dramatic 201 up-grade mods available, unfortunately it is also one of the most expensive if all new components are utilized! Therefore, we have elected to offer this mod on a special order basis and in an attempt to keep the costs down, we will offer this mod with used and/or re-manufactured components as removed from OEM M20J aircraft when available. Electric MSE Cowl Flaps and the special 205 pilots side blister cowl flap are popular options.

 

#101MM: 201/205 OEM Factory COWLING MOD: (for all 200hp M20's) Installed (exchange).	(w/some used components) (OEM new components)	$11,900+/- $18,795+/-
Reman O/Hauled OEM 201 Cowl Assy: *Notes: Call for exact quote and used parts availability on your specific Mooney as the supply is limited of re-man cowls.		$12,900+/-

Mine was converted by mooney mart in '98 by a previous owner. Even back then it wasn't cheap. I don't know how much for just the cowl. Everything was included in a single receipt.

HI Shadrach,

I haven't been flying at all since November. The holidays and now the weather are keeping me from getting my BFR completed. I really would like to give some numbers but I've yet to do the performance flights. Just need some warmer temps which should be coming soon.

Thanks, 

David

[Sabremech]

Work continues on the STC data package. I'm working on the drawings right now and every part has to have a drawing. This is time consuming and a little pricey. I'm going to have to disassemble my baffling one more time for final dimensions for these drawings. Maybe this will be the last time I take mine apart! 

Work also continues on the mold for the lower cowling without the oil cooler for those who have moved their oil cooler. I attached a picture of that mold in progress. I'm able to spend more time on this now as I received my STC for the LED lighting that has been in the works for over two years for Dassault Falcon 2000 cabins. Fun stuff. 

Thanks,

 David

[M20C]

Like many here, I've been following your progress since the beginning; VERY NICE work!!!  Just curious, are the "cheek" cowls for all vintage models the same and, if so, would it be much more expensive to make a mold for the entire upper cowl?  Seems like that would greatly simplify your AMOC list with the extra cost of layup being minimal.  This would require the new owner to reuse (and install) his original oil (and if desired, battery) "access doors but that should be easier than installing the forward cowl mod...

 

BTW, not criticizing at all; you have done AWESOME work!!!

 

Very impressed!

Bill

[Sabremech]

Hi Bill,

 I thought about an all new cowling briefly but knew early on I'd like to keep it simple and with the least amount of modifications as possible. There's also problems with the use of fiberglass long term in a full cowling like this, (M20J) comes to mind. I like the cheek panels for maintenance access and they are relatively close between airplanes, but one set will not automatically fit on another aircraft. It's easy to tell these were hand built. My mod is not all that difficult to install and my plans are to make it easy on the owner and the installer with what I'm currently planning for installation.

 Thank you,

 David

[M20C]

Thanks David!

 

Looks great so far ;-)

[JJ - M20E]

I have a 1965 M20E.   It was my grandfather's Mooney, so my airplane will always have more than just monetary value for me.  I am very interested in your work as my grandpa and I always talked about the LoPresti cowl.   Lo Presti quoted 25K in hardware alone to do their modded cowl.   I can't do that despite the looks, the improved RAM air, the cooling, and the speed improvements.   I think about it a lot though.

Equally as expensive is an M20 turbo for about 30K in hardware.   This modification also requires a J cowl and that is about as expensive as the Lo Presti cowl and a performance exhaust.    Hmmm... since you are removing my RAM air option from my M20E (because I probably will buy your cowl), you should think about an STC for turbo normalization on the vintage Mooneys that works with your cowl.   Maybe starting with the 1965 M20E series...     I don't see anyone else asking you with this absurd (but very hopeful) suggestion. 

I wish I was talented enough to do what you are doing.  Good job on your innovation and work.  It looks great.
