So, we with all the talk over the release of Skunk2's intake manifold along with our ported RRC intake manifold lying around, we decided to test them against the proven almighty RBC.

The engine we're testing on is a k24/k20 frank. 12.5:1 stock bore, rcrew header, 3" exhaust, 70mm TB, IPS K2 iron core cams.

Installer notes: the Skunk2 manifold puts the TPS right up against the radiator hose. We weren't initially too concerned since we're just testing but if permanent, we'd need another radiator hose. Skunk2 manifold is the easiest out of the 3 to install (only because of the hole between the runners for a gearwrench to fit and actually ratchet. We cut the Skunk2 manifold just like we would a unmolested RBC just for simplicity of changing out these manifolds quickly with the car strapped down.

The manifolds

The car with the RBC

The car with the RRC

The car with the Skunk2

The graph with all 3 tuned best runs overlayed.

all in all, these 3 manifolds seemed to make about the same power. RBC/RRC made most peak. RRC lost a little on the midrange. RBC/Skunk2 tied in the midrange. This only happened after cam angle changes were made. The Skunk2 manifold wanted more cam angle down low and little less in the middle, up top, same as RBC.

That's allllll folks.

Thank you Suja

Jdmdctek · 08-23-2009, 04:31 PM

thanks for taking the time out and letting us know how the sk2 compares to the others. glad i didnt purchase one =P.. i know that the rbc will make up around 300hp... here comes the banwagon to bash it lol

Great work Jason, your efforts will be well appreciated by k20a.org community.....

Nalos · 08-23-2009, 04:44 PM

good test

allmotaitr · 08-23-2009, 04:46 PM

why did you test a ported rbc to a non ported sk2... but at the end the sk2 made the same amount of power as a ported rbc.

judging from the photos, I think SuJa is referring to 70mm TB port match on manifold.

Jason please confirm.

Jason please confirm.

opps it a ported rrc manifold... isnt the rrc manifold better then the rbC?

Refer to above.
At least its as good as an rbc, without the need for an adapter... still really not worth it though.
OEM casting quality > all.

The test was RBC versus Blueprint ported RRC versus Skunk2 only because we had the ported RRC lying around.

Lol, beat me to it zerotraction.

Heh, thanks for taking the time to test it. Much appreciated

thanx for the testing , at least we know what to expect from these manifolds

**ilrider78** · 08-23-2009, 05:08 PM

Thanks to Suja1

geoscranny84 · 08-23-2009, 05:14 PM

almost bought a skunk2 mani............what a good ting !!!

Respect for all the Proof............

EG6VtecR · 08-23-2009, 05:24 PM

thanks pb16b/Suja1 good work guys.

so the retail value of the k-series skunk2 manifold should really be around the price of their B-series one $260-$270

KON · 08-23-2009, 05:27 PM

Thanks to all the work done by the guys at Suja. At least no one was hurt in the process...I'm staying positive

**jones83** · 08-23-2009, 05:28 PM

big ups to suja for the test. if u were weary about buyin the mani before......

sujinX · 08-23-2009, 05:36 PM

man thanks for the dyno tests! this is some great info for everyone who's thinking of jumping on to get the sk2 mani over the rbc.
