I would be concerned about 9 CR and the 10lbs of boost. As is, if the heads are optimized I woud think you should have closer to 180 HP, but I am not familiar with that cam, and am only relying on my sence from other engine specs I have gathered over the years. Maybe someone can run it on a dyno program for you?

Just a question, dont you think the web 121/125 is a bit wild for a 1.25:1 ratio rocker?? With the specs gicing a cam lift of 11.3mm at 270 deg (0.050"), it is about as steep, if not more, as a Engle 140 - which has 10.77mm cam lift and 274deg 050. Isnt that a recipe for disaster??

Tony, I dont understand your question...I got the W125 cam NOT the Web 121/125. As for the W125 is to wild with 1.25:1 RR, I talked (emailed) alot (>15) of people to get there feeling for the cam and more than 50% of them was running 1.25 rockers. there are a few beetles here near me that are running this cam and rocker combo, one of them are an offical nordic beetle cup car and they recomend this cam for my engine. But as this is my daliy driver it's on the wild side, but should be okay for street...
