This is what I found...
231/237 duration @ .050,
0.598/0.595 Lift, 0.307/0.307 Gross lift
112 LSA installed on a 110 CL
@ 0.05 ~10* overlap
IVO: 5.5 BTDC
IVC: 45.5 ABDC
EVO: 52.5 BBDC
EVC: 4.5 ATDC
I cant find a 231 or 237 lobe with the same lift as what I found to figure out its duration at .006 and 0.200. I pretty sure tsp upgraded to the 233/239 from this cam a while ago, when they were using XE-R lobes for most of their cams.
An educated guess based on XE-R lobes would be 281/285 duration @ 0.006, 153/157 duration @ 0.200.
This would give you:
@ 0.006~59* OL
IVO: 30.5 BTDC
IVC: 70.5 ABDC
EVO: 76.5 BBDC
EVC: 28.5 ATDC
@0.200~-69* OL
IVO: 33.5 ATDC
IVC: 6.5 ABDC
EVO: 12.5 BBDC
EVC: 35.5 BTDC
