Have the JUN and HKS cams been dyno tested against the JWT's..? I dont remember reading about them in teh shootout...just curious...
HKS cams were not available until recently so I have no direct opinion other than HKS stuff is generaly good quality.
JUN refused to take part in the cam shootout although from testing done by myself, there cams are close to the S3 and S4 JWT grinds. The JWT cams make slightly more power in my testing. JUN stuff is high quality and they don't make junk
Zex cams are ok for the two biggest grinds, don't bother with the two smaller grinds, still JWT comes out on top.
Tomei has the best bottom end but the worst top end of any cam I tested, still decent cams and the cheapest.
JUN, Tomei, HKS and Zex cams are all pretty good but the JWT cams have better area under the lift curve and have better valvetrain harmoincs. With the ECU that is tuned for the cams, the power is great and the powerband is wide.
The junk SR20 cams which are proably not even avalible anymore are Bullfrog, Crower and JG. Don't touch those with a 10 foot pole!
In my testing the JWT cams did better than the SCC tests but I used an ECU tuned for the cams and SCC did not.
