i know they produce more power than most of the popular cams including HKS etc. i have no doubt in the power it makes but hows the quality compared to others ? and for anyone running them how long have you been running them and do you have any problems mechanically ?
thanks

 

bump. will check back tommorow.

 

I guess I don't count, just installed them last week, 350 miles on them... check with turbotrix if you want more details though

 

over a yr. still running great!

 

thanks. any more people ??

 

Had for 9 months, no problems other than crazy top end power.

 

I thought comp 280's and HKS 280's had the same specs?

 

cool. wasnt sure about american made parts for the evo.

 

Comp 280s are the cheapest cams that offer the most lift, even over the HKS 280s

 

That isn't going to be of benefit for a stock head.

Comp Cams and HKS cams do not share the same specs. Note: The timing of the Comp Cams is such that they will not make best power installed straight up.

FYI

 

ISP in Maryland is making great power with the Comp 280's. I have them in my car and definitely cant complain. They have just about the highest lift you can go on the stock valvetrain without upgrading.

 

i have had them in for 16 months..i cant complain..i love them!! ..but i am starting to get a lifter tick.

 

Why is there no benefit for the stock head? I figured the the stock turbo would be more of a bottleneck than the head. No?

 

Someone mentioned their cams being made by Crane. Additionally, they refer to said cams as 'their spec'.

 

Because flow data reveals the stock head is 'dead' above ~10.2mm lift.
