In addition to last entry through the tuning of the F20C engine I want to subsequent performance chart from ASM 2.2l Type-R motor show.
ASM uses the Toda 2200KIT with 87.0mm pistons and 90.7mm stroke, producing a displacement of 2156cc. Additionally Toda A2 camshafts and valve springs Toda used. Around the engine were a ASM revised throttle, manifold and ASM ASM installed carbon Ansaugbox. As for the controller optimization, working together with ASM GT Works . In the performance chart above can be seen, however, clear that the VTEC starts at about 6000rpm, so I think that not too large changes were made at the controller. The resulting power is 276PS at 8250rpm and 246Nm at 6500rpm about. The diagram also the difference that make up the see the camshafts (compared red and blue curve).
These are not like the 300HP Arvou S2000. Why the difference, although similar products are used? Arvou used on the one hand Toda 2200KIT with 87.5mm pistons, increasing the displacement to 2182cc. The compression is 12.25:1 slightly higher. This, however, is far from a difference of more than 20hp out. What more is involved, are the individual throttle bodies and the individually chosen controller. Moreover, it may well be that Arvou used aggressive camshafts, such as Toda B or even has performed Toda C, and an in-depth treatment of the cylinder head. Finally, it also plays a role, have been made on what kind of performance test measurements. The results vary sometimes quite considerably. All in all we can say that with a 2.2l kit, with the camshaft and the right products are perfectly feasible aspect of the engine performance of 275-300hp.
