Here's the specs for the Spoon cams:

Intake: BTDC : 15,5
ABDC : 60,5

Exhaust: BBDC : 42,5
ATDC : 22,5

at 1mm lift

 

 

Based on Valve lift @1mm seat:

Skunk Stage 2's In. Closing 49 ABDC
Skunk Stage 3's In. Closing 52 ABDC (They have 267 duration & are NOT 270!)
.....But, if they where 270 dur. the In. Closing would be 55 ABDC....

Also, if you have some specs for other cams performances CAMS specs, I can calculate the overlaps as well.

 

supposedly the skunk2 1s are 43 degrees, but that seems odd since ITR cams are 45 degrees. I would think that the skunk2 1s would be greater than ITRs.


gsr - 40
itr - 45
skunk2 stage 1- 43?
Skunk2 stage 2 - 49
Skunk2 stage 3 - 52
Toda A - 45
Toda B - 50
Crower 63400 - 36
Crower 63401 - 40
Crower 63401T - 33
Crower 63402A - 40
Crower 63402 - 41
Crower 63403 - 46

 

good info here
