K-Series Dyno Data: Still More

Aug 24th, 2010

More third-party dyno data comparing Skunk2's Pro Series Intake Manifold against Honda's RBC manifold. Philadelphia-based Import DPS conducts the shootout on its customer's '07 Civic Si on its in-house Dynojet. Click on the dyno graph below, where you'll see significant horsepower and torque gains past 6,000 rpm. All gains are back-to-back without any tuning...just a straight manifold swap. Also, go here for more K-series intake manifold dyno data.

The Specs:
2007 Civic Si
12.5:1 compression ratio
88mm x 86mm bore/stroke
Drag Cartel Stage 4 Cams
Skunk2 Pro Series Valve Springs
Stock head and throttle body
Skunk2 MegaPower Header
Full Race three-inch exhaust

The guys at Import DPS say that next up are Skunk2 cams, more tuning, and Skunk2's soon-to-be-released drive-by-wire throttle body.

Go here for current pricing and to learn more about Pro Series Intake Manifolds for Honda's K-series engines.

This wasn't posted but the car wasn't tuned at all. This was simply removing the Stock restrictive RBC and installing the Skunk2 Intake Manifold. We are excited to test the DBW TB as we are sure it will release tons more power in this engine.

Good point, Rick. We just updated the text to show that.

Interesting numbers. I wonder if there is a baseline to compare the gains of this setup on this low reading dyno. my assumption for what is done to the engine. also, hope to see a tuned version of this setup to compare. would be nice, before installing the skunk2 DBW TB.

Ulisses G,

The car baseline was a tad if I recall 174 WHP with 6.5 miles on it. We strapped it down on the dyno within 1 hour of me purchasing the vehicle. Sadly enough, we lost that hard drive to some water damage 2 years ago. But it was in the 174, 175 range.

Great numbers with just bolt-ons and compression ratio change. It seems based on the dyno sheet that the car becomes slightly rich right before it hits vtec and needs more fuel. When tuned I think that if the vtec engagement is lowered to 4500 rpm and a good fuel delivery system, power would increase 5-10% at least. With the Skunk2 DBW TB and a few other goods this car could come close to 300 whp.

If the car is rich it DOES NOT need more fuel.
