Some on paper comparisons,
Manufacturer claim -
1. Neo CPS - 125hp , 150Nm (DOHC CPS)
2. Civic SIR (EG6) - 170hp, 152Nm (DOHC VTEC)
3. Civic Vti (EG4) - 130hp, 138Nm (single cam VTEC)
Based on paultan dynotest there is a loss of 12% for hp & 14% for torque (Nm)
So the figures are :
1. Neo CPS - 110hp , 129Nm
2. Civic SIR (EG6) - 149.6hp, 134.1Nm (B16A DOHC VTEC)
3. Civic Vti (EG4) - 114hp, 118Nm (D15B SOHC VTEC)
So in comparison we can see that the torque difference between a B16a & CPS is not that great around 5-6 Nm difference, but hp of the CPS falls way short of the B16A & even less than the D15B.
In theory, From these figures I would say in a 3 way drag from a standstill, the CPS can start as equals to the B16A to around 4500rpm but the CPS will fall back at high RPM's & the D15B will eventually catch up to the CPS due to the higher powerband of the D15B. (assuming same weight & gear ratio)
IMO, the CPS has potential, but in stock form its hp rating isn't that impressive as its even lower than a SOHC VTEC engine. The torque might be on par to the B16A but thats bcoz their both 1.6 L, but the D15B is a 1.5L engine. A normal 1.6 DOHC engine could get the figures of the CPS engine (lets say a 4G92)
With the use of valve timing mechanism the horsepower rating of the CPS should be around the 140-150hp area to really show off its technology...mind u the comparisons are to a 16 year old Civic!.....
Maybe it was too costly for proton to achieve reliability with the CPS to achieve higher horsepower ratings....so its really up to the tuners to R&D the CPS so it can be a real contender to VTEC (a least for B16a, its still a long2 journey to K20a territory)
Just some points to ponder
