THESE DYNO TESTS WERE CONDUCTED FOR OUR PERSONAL USE. WE APPRECIATE THE INFORMATION THAT HONDA-TECH PROVIDES SO WE DECIDED TO GIVE SOME BACK BY SHARING OUR RESULTS. INTERPRET THEM AS YOU WISH.

Today we tested some new camshafts by Skunk 2 Racing. We had the Pro Series 1 and Pro Series 2 cams to test on our motor.

The dyno testing was done at Abacus Racing and Machine in Virginia Beach, Virginia. The dyno was a DynoJet 248c. The conditions were humid; we had heavy rains and lightning and thunder on and off all day. The temperature was around 88 degrees. We apologize for not having air fuel graphs but the storm wiped out the dyno jet’s wideband so we had to tune off of an AEM UEGO wideband gauge in the car.

Specs on the motor:
-EG Chassis
-3 years old
-84x89 B20/VTEC
-12.5:1 on JE pistons
-Eagle Rods
-Stock B16 head
-JG Springs and Retainers
-Skunk 2 Intake Manifold
-Stock Throttle Body
-RC 440 injectors
-Hondata
-JG Edelbrock 2 piece Pro-Flow race header with Cut out
-Type R Transmission
-93 Octane

We made some baseline pull and tuned it to a best of 209.6WHP @ 8150rpms and 153ft-lbs @ 6100rpms. Definitely not a bad set of cams at all.





When we put the Skunk 2 Pro 1 cams and tuned them, we got 214.6WHP @ 8150rpms and 152.0ft-lbs @6100rpms.






When we compared the Pro 1s to the Stage 2s, we saw what the hype was about; it was definitely validated tonight. Below 5650rpms, the Pro 1s power and torque dominated the stage 2s. This is due to the larger primary lobes on the Pro Series cams. Above 7500rpms, the power and torque also went up.



The Pro 2s idle very smoothly, actually even better than the Pro 1s (on this particular motor/tune). The Pro 2s performed as expected; they made power and they made torque. This setup put down 214.7WHP @ 7950rpms and 155.4ft-lbs @ 5900rpms.






The Pro 1s and the Pro 2s are similar cams. All the way through the rpm range, the Pro Series 2 cams make more power and torque than the Pro 1s. The graphs however, have almost identical slopes.




Stage 2 vs Pro 1 vs Pro 2


SUMMARY
Today's test was only to test the differences between the Skunk 2 Pro Series 1 and Pro Series 2 camshafts. Luckily, our test motor already had Skunk 2 Stage 2 cams in it so we thought we would test all 3. The information learned from today’s results is for general knowledge. This is what these cams made on our motor with our tuner on this day with this dyno in these conditions.

We would like to thank Don F. for letting us steal these cams to test out. (Because we only had dyno time on these cams, we felt that the Pro 2s needed to be “street tested” so we took them for a Friday night test session. With the money we made tonight, we’ll be able to buy them from you! ). Thank you to Shad at Accuracy Automotive for tuning the car. Thanks also to Dan for providing his car to test on. Thanks go to Seth from Innovative Cylinder Head and Machine for making all this happen and doing all the “cam
work. Finally Abacus Racing deserves a big thank you for providing the excellent dyno facility and open door policy. All these guys are good people who make things happen.

 

that is a great comparison between the 3 cams.thanks for taking the time to show us.

Nice gains and nice info. That set-up is screaming for some porting to be done!

very nice guys! i always wanted to see how the pro1's & stage2 compared to eachother.

 

arent the pro 2's suppose to rev higher?

just a question

 

Thanks for the information that you provide for the Honda-tech community.

The motor is being chocked by the head and throttlebody.

Thanks for sharing that information, its always nice to see these kinds of comparisons.

 

Thank you for posting your end results

Thanks for doing the test
Very informative. The guy who owns the car should seriously think about getting at least a mild port and a better throttle body.
Good work gentlemen

 

just a quick Q for the initial poster, what kind of idle (specifically rpm) were u able to get out of the pro 1 cams?

 

Dont forget who's idea it was to send you guys those cams in the first place

 

great info.

 

The head is actually scheduled to come off here in a couple weeks to get ported by Seth at Innovative CH&M. Flow is definately restricting this setup.

Well it was more of a lopey idle than an RPM specific. If you are worried about a consistent idle, just open up your butterfly at idle and it'll be around 1500rpms and stay pretty close to that. There wasnt a problem getting the car to stay running with the Pro 1s, it was just the idle kept jumping around because of the big primary lobes.

Hope that info helped and didnt confuse you. If not, just ask again. Maybe i can better explain

yeah man. Im sorry bro. We definately appreciate you hookin us up with the right people. Seriously, we'd probly just now have a set of Pro 1s in our hands if you didnt hook it up. matt said he'll give you a call here in a few.

TBONE =

 

Damn not much diff between them.

good right up thanks man!

 

I'm starting to love these Skunk2 Pro Series Cams.

 

Also curious about how the piston to valve clearance was. Did you clay the motor before installing the Pro2?

 

this particular motor was not clayed with the pro 2s for a couple reasons. Back when it was originally put together, it was clayed and had plenty of clearances everywhere with the Stage 2s. We had degreed the 1s and 2s in a couple motors recently. Even in a comp4 race car with heavy modifications (including big valves), we had enough P-V and V-V. We felt that for this test we could do without it.

 

Nice job on the test. Get in some air and one of Dave's or Randy's headers and you will have a REAL happy customer. The 2's should peak a little higher so I think you are at the end of a stock head and throttle body's range. How much money did you win?

 

Holla! can i get a Abacus Racing Tshirt?

 

nice test. nice to see someone else is putting in time doing some testing.. now i need to put the pro2's to test in my engine... one day.... work sucks sometimes.
