Dynoed some Pro1's VS Skunk stg3's on a GSR. I am waiting for some Rocket 22xx cams to compare. At this point I am impressed with the Pro1's.
GSR with 11.5 comp. Wiseco's, Scat Rods, Ported head, Matched SK2 intake, 62mm throttle body, Omni springs-retainers, "R" intakes, Omni EX. valves, 92 Octane Exxon gas, SMSP header, 2 1/5 ex.
TQ@ 3500 139.2 vs 128.1
4000 143.1 vs 131.5
4500 145.1 vs 134.5
5000 148.1 vs 137.6
5500 146.6 vs 139.
6000 148.2 vs 142.5
6500 145.9 vs 135.
7000 150.7 vs 149.7
7500 152.7 vs 150.5
8000 150.8 vs 149.2
8500 141.3 vs 143.8
8700 138.0 vs 140.00
The STG.3's on the GSR made more power from 8100 RPM to 8750 (redline) but were killed before that. I will post grafts when avail.

 

Nice torque difference down low.

To my understanding those cams have similar VTEC lobes but bigger primary lobes than Stage1,2,3 cams ?

Is the idle affected at any point ?

 

i think im going to get some pro 1's soon

 

Nice numbers.

I don't have a good feel for what a torque curve looks like from just numbers, so I converted the numbers you posted to a excel graph. Hope you don't mind.

I'm planning a 2 liter build almost exactly like yours so I'm hoping my numbers will be similar...

i'm guessing blue line pro 1 ..graph show both HP sk2 stage 3.. thanks for dyno

 

Sorry, I corrected the graph and edited my original post.

The blue are the Pro l's and the red are the Stage 3's.

Looks like the Pro l's beat the Stage 3's from prolly well below 4k all the way to 8k, then the stage 3's show a slight advantage.

Remember... Peak numbers don't win the race.

 

Just found out I will not be getting the other (IN) m22xx until next week. Will post nembers then. Wish I new how to do the EXCEL graph, need to wait on my daughter. I have dynoed the alot of cams ( Sk1s,Sk2, Sk3s', several custom grinds, Web customs, Buddy Club 4s', M24x's, Crowers, Kents, etc. and at the moment like these as the best street cam. And I am not a dealer. Myself and T-Bone got some to test. Kudo's to Dave at Skunk.

 

Thanks for the info Don! Would love to see the m22's against these pro 1's soon

 

looks good don

power is still climbing by the excel sheet. are more gains realized past that redline in HP???

i was just looking and do not see a HP #'s listed by donF, did you use smoe math to ge those, or were they given and i missed them somewhere???

 

When I get the M22xx cams will post the numbers. I really did not post BHP numbers because then there will be ( Bert got this on his ) this is not a trick motor, GSR with ported head ( Portflow, Rocket, RLZ, Me, Alinez, Endyne, Skunk, JG, etc.) 11.5-1, good rods, 62mm Throttle body, really nice SMSP headers, 2 1/2 exhaust.
BHP @ 4000 109 vs 100.1
4500 124.4 vs 115.3
5000 141 vs 131
5500 153.5 vs 145.6
6000 169.3 vs 162.8
7000 200.8 vs 198.8
7500 218.1 vs 214.9
8200 232.1 vs 236.7
8600 229.1 vs 233.5
8700 228.5 vs 231.9

 

damn, those are some linear curves on the Pro1's.

All these awesome new cams coming out, makes me want to go vtec.

We did them on Boosted Hybrid's car (regular m22's) They were the same on vtec and a few less down low... They should idle better though

 

Thats sweet. I need to get in touch with Skunk2.

 

I guess I should say the SMSP headers, that were for a 2.0 litre, made between 7.5 and 10.3 BHP more than my DC 4-2-1 with a 2 1/2 outlet. As I have not paid for them yet i didn't want him to know the improvement. Now I want some for a 1.8.

I think you were asking if there was some magic math used to convert the torque at a given rpm to torque.

The math is very simple. Take the torque (ft-lbs.) multiply by the rpm and divide by 5252 (that's just a conversion factor).

Example:
148.1ft-lbs @ 5000rpm =&gt; 148.1 x 5000 / 5252 = 141hp.

You can easily set those equations up in excel and convertthem and graph them from there.

I know the formula, and I have the dyno sheets in 100 rpm separation, plus the graphs. Posting them from the DEPAC engine dyno is the problem, I can build engines, need my 19 year old to help post the numbers .

 

to the best of my recollection, the skunk pro1's have like 12.5 lift on the intake cam, right?

 

Wow I'm impressed. That vtec croosover rpm range is much smoother. What a good looking graph!!

 

Yes, the same as the SK 3's less duration on the vtec lobe . .494 lift @ .000 on the indicator.

 

I'm impressed ..... are the Pro1's in stores yet.....

 

I think they are as T-bone and I got some to test and do not sell Skunk products. Try there dealers or call them . I charge them to dyno their stuff, some you will hear about, others you will not (it did not work) Skunk, Rocket, Omni, SMSP,Jenvey ,have agreed to let me post there results.

 

JHP has the Pro 1's on their website.

 

awesome thread! wish i had the $ to get some pro 1s ...verrrry soooon

 

Hey DonF,

I wasn't posting the math for you, I figured you knew how to get the HP, and prolly already had it (which you did...) "JohnZM" posted earlier asking about "some math" (if I remember correctly), and was just explaining that the math was pretty simple... Sorry for the confusion

Are all of those numbers "crank hp"? Those are still nice numbers, but I assumed (I swore I wouldn't do that anymore) they were whp, which makes them almost unbelievable from a 1.8L, and only 11.5:1 (and I guess they were unbelievable...)

Thanks for the contribution,
Adrian

 

makes you wonder how come skunk doesn't make a new cam using pro1 primary and stg 3 vtec ... that would be a king of a street cam.
