I have currently HKS 264 Cams I/E I have a friend selling comp 280 cams, I was debating on swapping to the comps.

Has anyone have any experience with both of these cams, and suggestions to swap to the 280 or stay with the 264's?

I am hoping to go meth or FP red this year.

Thanks in advance

 

The 2 arent really even close to the same. HKS264s are honestly little better than stock and the 280s are nice and thumptastic. You will make significantly more power with the Comps.

 

Why don't you go with a nice set of 272/272's?

 

look at my sig
93+meth and 280s comp

Im getting the 280s for a really good price one of those hard to find offers.

 

Reason I was asking cause i saw this in the cam sticky thread:

Comp Cams 280+
Advertised Duration - 264 deg Int / 265 deg Exh
Effective Duration - ___ deg @ 1mm Int / ___ deg @1mm Exh
Lift - 11.0mm Int / 10.4mm Exh
Lobe Centerlines - 104 deg Int / 112 deg Exh
LSA - 108 deg

HKS 264
Advertised Duration - 264 deg
Effective Duration - 206 deg @ 1mm
Lift - 10.8mm Int / 10.2mm Exh
Lobe Centerlines - 110 deg Int / 110 deg Exh
LSA - 110 deg

 

nice numbers.. now i want my tax return to get here now..

 

Yes. definitely look at the lift.

 

More importantly its what isnt pictured. The advertised duration is a very small part of the puzzle. The only truly important measurement is the duration @ .050 as this gives a much better idea of what the ramp rate is and the amount of power a given cam combo is worth.

HKS264s are almost invisible in the car, the comps are noticably lumpy at idle and definitely make more power.

 

I switched from HKS 264/272 to Comp 280s. It was definitely worth the switch. At least 15 whp gained and better mid-range and top-end.

 

Nice thanks for all the advice

 

diver mod needed...lol...
125mph trap speed is insane...u should b at low 11s...

 

if you are going with comps 280s get springs and retainers, I didn't so now I'm paying for it I got collapse lifters and I bend my valves, rev the car to much and its hard not to do it with the red cause the power never stops so you just wants to keep going n going


that was my first pass with the new set up no traction and hit the rev limiter, did 2 more passes but it was worse, then my valves went out the door, so hopefully my car should be ready this week to try it again
