I personally think it would be awesome if DSPORT could do this exact same test again only with a Evo 9. I would like to see what influences MIVEC has on the outcome of whp and wtq using MIVEC specific camshafts. I also would've liked to see them test the GSC S1's just for fun. All in all this was a great test and a phenominal article by DSPORT. It really helped me narrow down my choice as to what camshaft I wanna run. Based on my needs I will probably end up getting either Kelford 272's or GSC S2's.

Yeah it would be interesting to see where the stock Mivec cams sit, I've heard they're comparable to HKS 272s

I agree that a list of engine mods would be helpful. A cam that is a beast on one engine could turn another engine into a dog.

Also, peak HP/TQ numbers don't really tell us all that much.

Still, interesting thread.

I posted the peak numbers because that's what everybody seems to be interested in. The article is about 20 pages long, no joke. Every cam tested got its own page with a ton of information. The article is a must read.

^^ This. Actual dyno graphs would be much more valuable. Seeing the full power curve of each cam would be much helpful in helping people determine the right cam for their goals and set up.

I need to pick this mag up asap!!

So which two issues have it? I looked up the February issue and it has the first four but the rest are coming out in March's issue or what?

Both issues are available now.

Here they are:




The first issue gives details about the Evo they are using. IMO, its not a fair comparison to most Evos on the road. It's using an JM fab aftermarket tubular exhaust manifold, AMS intake manifold, and FP GTA FT3586R turbo. However, the setup never changes so it does serve the primary function of comparing cams. The first issue also gives a complete breakdown of how cams work and how the different grinds produce different results. Also details the specs and how to compare different grinds. The three cams tested in the first issue are also included in the second issue.

The second issue is all test results. They list all of the data and analyze it. Peak numbers meant nothing to me. I was far more interested in the power-band that each set of cams delivered.

Not all of the cam options were tested. I was interested in seeing the following get tested:

Cosworth M2
Cosworth M3
STM 650
BC "Stage" 2
BC "Stage" 3
GSC S1
