A2 Cam Specs

[Payntech]

We measured the A2 cams yesterday.

Intake:
Primary - 176 deg @ .050" .282" lift
VTEC - 227 deg @ .050" .458" lift
Seconary - 186 deg @ .050" .263" lift

Exhaust:
Primary - 187 deg @ .050" .254" lift
VTEC - 218 deg @ .050" .397" lift
Seconday - 182 deg @ .050" .262" lift

*Note: all measurements are at the valve with lash.

For comparison here are the K24 cams that we measured.

Intake - 197 deg @ .050" .359" lift
Exhaust - 187 deg @ .050" .372" lift

I think I am going to send the K24 cams out to be reground and see what we can do. I am guessing that we can pick up about 10-15 whp with a decent grind. Which should put a well tuned car in the 165-170 whp range.

I will let you know.

Thanks,

Thanks for the numbers, I would assume that the cams for the K24 are close to the numbers you would find on the A3? Do you have any numbers on the A3 cams?

I do not have a set to measure. I am sure the specs are close.

I know nothing about cam grinding.
So we could get the A3 cams grinded for some decent gains.
How much $$ does cam grinding usually cost?

I have the factory specs for the A3 cams somewhere. I'll post it when I find it.
