IT was designed for low and mid-range torque with the added VTEC for some top end.. the intake manifold is totally different to all other B-series.. with the dual-tract intake runners operated by a butterfly valve.. is designed to optimise low-down power and mid range flexibility. the VTEC point is set lower with this tuning on the B18C usually about 4500 and is almost inaudible untill the secondary butterfly opens some 1000RPM later however there is less 'kick' in the change. this is actually GOOD because the ultimate tune would be a perfectly linear power curve.. the B18C through it's 2 stage intake manifold, increased displacement (over B16A) and use of Variable Valve timing (VTEC), is able to have a very linear power curve as a result.
