Have you the value to put on the pulleys for adjusted this with my camshaft?

Please let me know

ALWAYS set up aftermarket cams with dial gauge and degree wheel.

Lobe centre lines are:

HKS 2202-RT065 272 Inlet Cam: 110 degrees ATDC
HKS 2202-RT064 264 Exhaust Cam: 103 degrees ATDC

When cams are set up correctly, set ignition timing to 10 degrees BTDC with E1 and TE1 bridged.

for the Exhaust 264° BTDC is 108°

i have us this technic with dial gauge and degree wheel but i think that i have not do it correctly.

in first in will be test to adjust the ignition and i let you know.
Tomorow i see for buy flash lamp.

why i can put the same value on my camshaft pulley that other person who use the same Camshaft?

for the Exhaust 264° BTDC is 108°

i have 108 you can see my doc:





I think that they have a problem

[arnaud_mr2]

i have find the information about the stock camshaft:

Specs of stock ST205 cams:
Ex, max cam lift 8.2 mm, 236°, max lift at 118° BTDC, open 56° BBDC, close 0°
In, max cam lift 8.7 mm, 240°, max lift at 113° ATDC, open 7° BTDC, close 53° ABDC
Overlap 7°


spec of my HKS intake 272 camshaft:
duration 272° cam lift 9.2, max lift at 110° Ref 2202-RT065

Spec of my HKS exhaust 264 camshaft:
duration, cam lift 9.0, max lift at 103° Ref 2202-RT064


For find the value to put on my hks pulley:

Stock in 113 - hks intake 110 = 3° i do put 3° on my hks pulley for have the max lift at 110°.

And for the exhaut:
Stock 118° - hks 103° = 15° i do put 15° on my pulley for have the max cam lift at 103°

Are you ok with my calcul?
