[CL9] In search of horsepower

[aaronng]

One of our member's (NPcan) euro was pulling 147 atw with IHE and tuning. Then there's all the members from TSX forums that would disagree with you.

Considering stock CL9 makes 110 kw atw, Npcan's euro makes 33.6% increase over stock... Not bad for just bolt ons and piggyback don't you agree?

What was NPcan's stock dyno? I only see a value of 122kW on a Dyno Dynamics but that was with topspeed headers, Injen CAI and Haltech interceptor. He then dyno'd 143kW with WeaponR and Fujitsubo exhaust on a Dynapack hub dyno, which gives higher readings compared to a Dyno Dynamics dyno. So you can't compare the 143kW value to a stock 110kW achieved by another car on another dyno since the dyno & car are different and also because of the tiny fact that the Dynapack has lower loss through the wheels (since there is no wheel attached!).

CL9 at 1300 odd kg's is actually pretty light given its size and features, it's within 100kg of a dc5r, with more torque from the k24 to boot.

Features work against you when racing in a straight line or on track as these add weight. CL9 is also 1395kg for the base model and 1465kg for the luxury too. It is a fat car.

Re: lightened Pulley + flywheel. That's just.simple.physics. Rotating mass is the key.

Great for acceleration in mid range, but not at the top end which is where you are usually at when doing a 1/4 mile or on track. If on the street where it is more about midrange, driving to beat a DC5R will get your car impounded anyway.

Also, "real world" performance is a relative term. Hell, just by adjusting the CL9's Drive by wire setting will make a night/day difference to daily driving and perceived performance.

This one is a placebo effect, since the same perceived performance can be achieved by adjusting your foot.
