Running the Ielasi tuned in a Mugen MRX5-WC, gearing 16/20 on 50/46 and as fuel Runnertime TOP-16. Exaust: JP Racing 2031 with the Novarossi short conical manifold which I believe is the best exhaust system for Novarossi (based) engines.

The engine had a 4 hour break in in my heated oil bath bench and needed about 1.5 tank on the track to go on sharp. With small size tires (74/68) the engine comes to life and is one of the fastest on the straight. Also on low and midrange parts the engine has a powerfull but still smooth control even when knowing about the very high timings.

On full size tires (77/70) you will notice the engine looses some power but is still able to withstand the competition.

After 1.5 liter driving the pinch is still there which tells me a better material piston is used. I am very pleased with this engine although it has no 5 min milage!
