Anyone know the following STOCK specs for the d16a6 cam?

1) Valve Life
2) Duration @1mm Int./Exh.
3) Adv. Duration
4) Lobe Separation

Thanks

I've never seen the specs posted. I did measure to lope height on my CRX Si cam that I was using in a D15B7.

Doubt that info will help you though.

 

Hmm, probably not...thanks anyway though!

Anyone else know?

Ok what the heck, what was that measurment that you took?

Thanks

CRX Si 1990
Intake
base height 1.220, lobe 1.445, .225" lobe lift = .374" valve lift
Exhaust
base height 1.262, lobe 1.455, .193" lobe lift = .353" valve lift


Gude #HCCS07 (regrind)
Intake
base height 1.135, lobe 1.385, ..250" lobe lift = .415 valve lift
Exhaust
base height 1.170, lobe 1.400, .230" lobe lift = .421 valve lift

Gude lists duration @ 241I/228E for that cam.

Hope this helps.

 

Thanks man!

Is that Gude a pretty aggressive cam grind? I was looking at the Crane turbo cam which has .394/.376 intake/exhaust valve lift. Which isn't as aggressive as the Gude one you posted..

Likely Gude specs are "overrated".........

 

how do you calculate the lift

 

lobe height - base height = lobe lift
lobe lift x rocker ratio = valve lift
