To mark the tenth anniversary of Ielasi Tuned, the Italian engine tuning brand has released the new GP9R23 1:8 Onroad engine as the icing on the cake of the trio of engines to be launched over the last month. These included theGP3R23 1:10 Onroad engineand the 1:8 GTGP5GTR23. With it 20 years since former World Champion Daniele Ielasi started tuning engines, initially under the IDM brand, his latest work is born from the basis of the new OS R2105 but customised in some aspects. These include Ielasi Tuned exclusive crankcase cap. An R2105 9-light cylinder but with tight fit treatment as in the GP9R22 to increase reliability. New lightened cooling head that results in a 8gram weight saving and a new customised crankshaft. As always the engine has other details already used in the previous version and as always each engine will be prepared and assembled individually .
