EdgePerformance (EP) was established in 2005 and started of building custom race cars and rally cars to customer specifications. EP specializes in turbo engines and engine management systems. On the way towards becoming who they are known for today, they have created an enormous dealer network, customer network, suppliers and not in the least experience and expertise.
During 2013 EP was certified as iRMT on Rotax 912/914 engines and sold both engines and spare parts as well as performing service, repair and overhauls. As of 2007 they have been converting aircraft engines with EFI (Electronic Fuel Injection) and Turbo chargers. Since this took most of their time and created a lot of work, they stepped back from the Rotax spare part market which used up all of their time, and now perform service/repair/overhauls of Rotax engines.
EdgePerformance is constantly looking to establish relations with more dealers around the world to support and install EFI/Turbo retro fit bolt-on kits for customers. They are now able to support and supply this popular kits to the entire market on their own, and are happy to welcome new dealers. EdgePerformance is constantly working on improvements and simplifying of their products.
EP has developed several kits for conversion and modification of Rotax, Jabiru aircraft engines. These range from fuel injection, add on turbo- or superchargers, ceramic and teflon coated pistons, big bore cylinders for Rotax, improved and strengthened crank- or camshafts. The performance improvements in power output is really spectacular to say the least.
For example: the Rotax 912S can be modified to a EP R912STi, a fuel injected, turbo charged 154 HP / 182 NM beast of an engine!
For the engine to be able to handle the increase in power some changes will have to be made: the crankshaft is welded on all the engines they build with their custom rotary TIG welding tool. This prevents the crankshaft, which is press fitted, from any torque twisting. The gearbox is also modified to cope with the high power output.
Fuel Injected Turbo
These kits are available for Rotax 9 series and Jabiru 2200 / 3300 engines. The supercharger kit is bolted on the back of the engine and in combination with a fuel injection kit will increase power. Turbo normalizing (maintaining intake pressure at sea level to a certain altitude) is also possible.
For the Rotax 914 there is a fuel injection kit available, as this engine already has a turbo. Included will be the EFI - ECU package and the carburetors will be removed from the engine.

Installing the EP EFI-ECU kit means no more Bing carburetors, synchronization problems and importantly: no more carb ice! The advantages are huge: smooth running, lower fuel consumption and equal cylinder head temperatures (within 5 °C). All of this results in a more reliable engine which lasts longer and is much cheaper to operate.
Big Bore Kits
Your standard, out of the box, Rotax 912S has a cylinder displacement of 1358 cm3 and this can be enlarged up to 1621 cm3 with an EP big bore kit. It is available in compression ratio's from 7:1 to 11:1 with a power output ranging 110 to 130 hp. It wil require 98 octane fuel for the 11:1 compression ratio kit, low compression ratio's may use the 95 octane fuel.
The 1417 cm3 big bore turbo kit (8.5:1 compression ratio) are billet big bore cylinders for the 912 / 914 series of engines. They are made from 4043-T6 alloy. It is dynometer proven at 160 HP. Normal output on a 914 is 135 HP. It is supplied with custom under cut EP forged pistons with teflon coated skirts and ceramic coated piston crowns. It must use 98 octane fuel or better.
Power output of the big bore kits is between 110 to 130 HP, you may expect fuel flow to be around 10 % higher with the same power setting as before the conversion. Included also is a 0-ring base which does away with the messy gasket sealer Rotax uses.
EFI Ignition kits are available for Lycoming / Continental engines too. Should you be into aerobatics then have look at the aerobatic kit for the 912, this will make sure that oil will flow even when flying upside down! A secondary alternator with a output of 32 A is expected to be availabe too.
EdgePerformance specializes in repair, service, maintenance and overhaul of all 2/4-stroke engines. They are specialized in the 503/582 and 912/914 engines with a full spare parts inventory, mostly for the Norwegian market. They also carry out work on Jabiru and VW engines as well. Upgrades are also offered to a 2000 hour TBO spec as well as EFI conversion or big bore kit installations. Contact them for a quotation on these options.
