SkepticalJohn Posted September 1, 2016 Report Posted September 1, 2016 This is not my system and I have no knowledge of it. I just saw it on eBay and thought I'd share. http://www.ebay.com/itm/142102700768 Quote
Mcstealth Posted September 2, 2016 Report Posted September 2, 2016 Wonder if it is the same member that has had one for sale here on the site? df Quote
DaV8or Posted September 3, 2016 Report Posted September 3, 2016 Are these STCs transferable and if they are, does that cost anything? Quote
M20F-1968 Posted September 3, 2016 Report Posted September 3, 2016 Yes it is the same person, namely me. I will not be using this system since I no longer have an F model cowling or airbox. I am willing to be flexible on price but need to keep an eye on what cost it took to rebuild the parts. This would be a great system for an E or F model owner as it truly makes an E or F a different plane. at 17,000 feet you will reliably have a 175 kt airplane burning 11 gph. As for flying the plane, you no longer worry about loosing manifold pressure, you keep sea level pressure up to 20,000 ft. It is essentially a bolt on mod but for a small amount of sheet metal work closing up the ram air door. The STC's are transferrable as the unit was built before the manufacturers put serial numbers on the STC's and before anyone (including the FAA) were concerned about it. It is a logbook entry and a 337 form mailed to OK City. I have both STC's (one for putting the turbo on the engine, and one for putting the modified engine onto the airframe). I have all diagrams referenced in the STC's, Install manual, parts manual, FAA POH letter. My e-mail is john.breda@gmail.com My cell is (617) 877-0025 This system will serve someone well. I can put you in touch with others that have the same system. Over the next few months I will be going through left over parts and try to clean up the hangar space. Quote

Just curious, IIRC, you have the Lo Presti cowl, is that so? What made you give up on the turbo and go the Lo Presti route? Quote
M20F-1968 Posted September 3, 2016 Report Posted September 3, 2016 If that question was directed at me, I am still turbonormalized, but have the system that started its life as the Turbobullet (originally a design of Rocket Engineering) It did not survive at Rocket Engineering as a fully turboboosted application (originally with low compression pistons in a J model). It then became a turbonormalized system and has worked well. It uses the J model cowling and J model airbox. It is the same essentially as the RayJay system I am selling, but the configuration in the cowling is different. The original RayJay has a manual wastegate, which can be better as you can take the turbo out of the system when at lower altitudes. The manual wastegate also allows a higher critical altitude since you can close the wastegate completely with no leak as with the fixed wastegate. I do not have the Lopresti Cowl, I have a J model cowling which I rebuilt totally. John Breda 1 Quote

The turbo system does seem pretty nice, particularly for those living in higher altitudes. How much work was it to fit the J cowling? Quote
M20F-1968 Posted September 6, 2016 Report Posted September 6, 2016 Putting a J model cowling onto an E-or F is alot of work. I started with no nose at all on my airplane hen I bought it. The original plan was to use the Southwest Tx STC'd coling mod and use the original RayJay that is now on e-bay. The mechanic I had made swiss cheese out of the Southwest Tx cowling, forcing me to do something different. Thus, I went to the J model cowling. I purchased a used cowling from Lopresti that was supposed to be "structurally fine", until you found the plywood stiffener fiberglassed into the underside of the top cowling. It was a year to rebuild that cowling entirely. Then came the 201 windshield, cowl deck, sidepanels and fitting the cowling to the airframe. Since mine is truely a completely rebuilt airplane, it was OK. It is alot of work and not for everyone. The end result very nice however. I even went so far as to change the structural cage to be like the new ones. The RayRay system that is on e-bay is for the original F or E model cowling and its respective airbox. Both turbonormalizer systems work similarly and use the same turbo. The exhaust pipes are routed differently. Either way, makes for a very different airplane. John Breda Quote
