Interesting what maptun requires: Exhaust, air filter , turbo, camshafts, forged pistons, clutch disk, al ic, fuel inj, fuel pump.
I thought that the viggen had special heat treated valves and pistons?
I wonder why the viggen, at least from maptuns prespective, needs any engine internal modifications. If you look at the stage 5 for a 9000 aero, stage 5 doesn't require any internal modification? Why is that?
Viggen engine:
"In addition, the engine features reinforced alloy pistons that benefit from oil-cooling jets at the base of the block that spray oil at the underside of each piston. The engine also features sturdier connecting rods, nitrided gudgeon pins and strengthened intake valves. To handle the heat, exhaust valves are made of Nimonic alloy - a high nickel content, heat-resistant alloy used in aircraft components subjected to high pressure and temperature, such as the exhaust nozzles in jet engines.
