Product Improvement Announcement
MotorstarNA is proud to announce that we now offer the SPC pistons and rings. The SPC piston kit uses a new piston design and modern technology rings.
The new pistons use a 3 ring configuration instead of the original 5 ring design.
The top compression ring is a plasma molybdenum ring that produces a superior seal while reducing friction.
The second ring is a tapered hook or Napier design that provides superior oil control. The oil ring is also modern design that reduces oil consumption by about 1/3.
The overall result is an engine that consumes less oil, more stable operating temperatures through all operating conditions. It runs smoother at idle and it starts more easily.
The factory engineer and test cell technicians were surprised at the test cell results. The engineer said of the testing, “After the breaking-in period we measured the parameters at all engine duties and the results were according to the documentation in force. After this we have set the engine at Cruise I and it worked at this duty for one hour. We did this test in order to determine the oil consumption. The result is amazing. The oil consumption at Cruise I is 510 grams per hour or 2.83 grams per HP (specific oil consumption) or 0.575 liters per hour (the density of our oil is 887 grams per liter”
Typically the M14-P consumes about 0.8 liter per hour.
He also said “Beside the oil consumption we observed also other improvements. The engine start is easy; the temperatures (CHT and oil temperature) are constant in time and the idle is more stable.”
The SPC piston kits are available in standard bore size (105 mm) and R1 first oversize (.15 mm oversize). Each kit includes a new piston, 3 fitted rings, a new piston pin, two new piston pin plugs, a new cylinder base gasket, two rocker cover gaskets, two new rubber tube for the push rod tubes new cylinder nut lock tabs and installation instructions.
The new piston is 34 grams lighter than the standard piston. The SPC kit includes a new piston pin plugs that are heavier to keep the engine in balance.
The standard size kit P/N 14-605-22SPC is $304.00 per kit.
The oversize kit is P/N 14-605-22SPC-R1 is $328.00 per kit.
There wil be an additional 5% discount on orders of 9 kits.
MotorstarNA will soon have these kits in stock at our Vermont headquarters.

How close is the piston design to those done by Monty Barrett? They sound similar. Pilots flying with the Monty Barrett overhauled M14P's have reported that engine oil remains original clean color after twenty hours at a time due to less blow-by with their three ring , closer tolerance pistons.

On the same token, do these pistons keep the same exact original compression ratio? Some folks have used this opportunity (changing out the pistons) to raise the compression ratio just a tad. Do you (George) expect an option to allow that with your offer at any future date?

No, M14P pistons are heavier and have larger wrist pin. Check with Bill Blackwell.

Hi all...
Anyone know if any of these 'new' pistons are suitable for use in the Housai 285 HP engine?
If not, anyone know of anyone developing any?

George.....this is good news! What is the compression ratio of these pistons? Are they just the pistons, or are we talking cylinders as well? Has any vibration testing been done? If so, what were the results?
Thanks in advance!
Barry

I generally try to put the information up on our web site. MotorstarNA.com.
I expect to put the cylinder kit prices and information up this week. I wil
also be posting some service information on cylinders, specifically the
service limits on cylinders and valve guides.

George, excuse me.
I got my names wrong.
Mr. Barrett would you please provide a location where I can read about what modifications you offer for the M-14 engine?
Thanks so very much,
