Skunk2 Camshafts and valve springs
Hey guys, i contacted skunk2 about the camshafts they offer for our baby and heres what they said....
Q: Hi, just wondering what the deal is with the camshafts for the S2000. Can you put just those in? Do you need valve springs or anything else with them? Are they streetable? Would you need an aftermarket ecu or anything? Any info would help.
A: Thank you for contacting the Helpdesk at Skunk2 Racing.
The S2000 camshafts make 15-20 HP and 18-22 ft/lbs of torque. They are a precision camshaft that do not require adjustable cam gears. They do require aftermarket valve springs and retainers, and are very streetable once you trim fuel under 1500 rpm.
If you have any more questions regarding Skunk2 products or policy please let us know. Thanks.
Whats this trimming the fuel stuff? Do any of you out there know if these are per say drop in camshafts and you add valve springs and away you go? What kind of tuning is required with camshafts? Are the benefits really worth it? Do bigger injectors come in to play at all? ANy of your guys' input would be awesome. Thanx

Trimming the fuel means adjusting the AF ratios with some type of aftermarket engine management syste (VAFC, AEM, Emange, etc.)
When Skunk2 cams first came out they made no gains, maybe they updated them but zero chance of 20HP just from streetable cams on an F platform motor.

I can't imagine why any manufacturer would change the non-VTEC lobes on a camshaft, unless it was designed for a boosted motor or a big change in compression ratio. Ask them for the lift and duration specs and the intended application for this cam.
THis motor has 6 cam lobes per cylinder:
Intake - 2 normal (may be same profile for both intake valves) and 1 VTEC
Exhaust - 2 normal (may be same profile for both exhaust valves) and 1 VTEC
If the non-VTEC lobes are the same as stock, the idle should not need any fuel trimming.

Also, the primary & secondary lobes (at least on the intake) are, in fact, different profiles. This is to induce swirl in the chamber to aid in fuel mixture.
