Stock Cam

something i thought about.. if the brian crower stage 2 cams have a lift of 410"/.410" then y do the skunk2 stage 1 cams have a lift of 0.449”/0.449”. on the brian cower site it says for the stage 2 cams that the cam "Requires kit BC0050" with a lift of .410.. then y does the skunk 2 stage 1 with a .449 lift only say recommends..if i have misunderstood something then please please correct me.. but something doesnt seem right

2nd he said if the paper that came with the cams said "Valve train upgrade is recommended" not "required" then the cams that i was sent were not stage 1 cams.

as per skunk2, stage1 TUNER cams don't need valvetrain upgrades. maybe you got the PRO cams?

unless they sent me pro cams in a box with the paperwork for stage 1 cams if they did that then yes.. but on the website they dont have pro k series cams..... also read my last post the one above yours... y would the stage 2 brian cower cam need springs when it has less of a lift then the skunk 2 stage 1 which doesnt require one

brian crower cams have more duration.

Have you called Skunk2 about this yet?  I bet they can provide a little bit of insight when it comes to needing a valvetrain upgrade.  My guess is that the installer fucked up and the timing was off.  If other people have used Skunk2 Stage 1 cams with the OEM valvetrain, and you got valve to piston contact, then it's either the install or you were sent the wrong cams by Skunk2.

i got the cam from chris off of gen7accord... he was selling them almost half price.

[timot_one]

He's running them in his car too.  Something isn't right here.  Sounds like the install.

[fatbastard]

yeah as per skunk2, even stage3 cams won't have clearance issues with stock engines.

[timot_one]

The only reason why you would have valve to piston contact is if the timing was off.  You can advance your intake cam up to 30º on a K24 Accord.  The TSX K24A2 comes with a 25º cam gear, but you can advance your intake cam up to 45º without valve to piston contact.  One reason for upgrading your valvesprings and retainers is to be able to accommodate the additional lift that most aftermarket cams give you.  My guess is that your installer fucked up and the timing was off enough to cause the damage or another thing that it could be is that your timing chain tensioner failed and your chain skipped a few teeth.  Usually, your timing chain tensioner doesn't fail immediately.  Usually it will fail over time with aftermarket cams.

[fatbastard]

is it then recommended to replace the timing chain tensioner at set intervals when aftermarket cams are installed?

[timot_one]

No.  It's suggested that you replace the timing chain tensioner with a stronger aftermarket unit.  There are 3 companies that make them.  Toda, Skunk2, and Hybrid Racing.  Hondata uses the Skunk2 timing chain tensioner on their 2 k powered land speed cars.  You can also get a discount from Skunk2 if you already own a set of their cams.  If it were me, I'd only use the Skunk2 or Hybrid Racing tensioners.  I don't know a lot about the Toda one, because I haven't researched it.  I do know that the Skunk2 and Hybrid Racing timing chain tensioners are not remanufactured OEM units, but are completely redesigned and new units.
