When running 1.5 rockers the 224/230 cam is .502/.510 on a 112 LSA and the 230/236 is a .510/.520 on a 112 LSA. What would it be when using 1.6 RR's.

Which cam will keep me from having to rev over 6000 RPM while making power?

 

NCC-224XL
XTREME
Comp Cams 224XL Camshaft 224/230 duration @ .050", .503"/.510" lift with 1.5 rockers, .536"/.544" lift with 1.6 rockers.

NCC-230XH
XTREME
Comp Cams 230XH Camshaft 230/236 duration @ .050", .584"/.585" lift with 1.5 rockers, .622"/.624" lift with 1.6 rockers.

 

the duration isn't changed by the 1.6's

 

~6000 rpm?

Go with the 224 or something even a tad milder like 218.

Of course you made no mention of the engine size?????

it has no effect on the total durraction, but does increase durration at .050 which is usually what you compare

 

Im sorry, what I meant was the lift.

.622/.624 lift on a 230/236 XE cam when using 1.6RR's

Need lift numbers when using 1.6RR's on the XE 224/230 and the 230/236 cams.

 

Pretty simple...divide advertised lift by 1.5, then multiply that by 1.6.

XE 224/230= .535/.544 with 1.6 rockers
XE 230/236= .544/.554 with 1.6 rockers

 

i dont think it wors that way

especailly since you did the lift

edit:
never mind, i thought you were thinking about durration

 

This is correct.

1.6 rockers affect lift not duration.
