Below is what I think the 20V L and N1 H will look like vs FS4 cams

That power curve for the 20V L and N1 H is way in its favor, much more power under the curve. This setup will be a great drag cam and street cam from a role.

Wow, im blown away by offers of money! Ive just been doing all this for myself, but more than happy to help the rest of the comunity along the way.
If Miko's predictions are right, then i will be a very happy camper.
If they dyno up how we hope, then these should be a popular cam. Only thing i'd like to try to complete the testing is N1's as well, so the Americans etc can compare what they can already get, vs the 20v hibrid cam.
Should it be called a stage 20v, stage 3.5..... Hmmm...
Pick up tommorow with any luck, otherwise friday, its over an hours drive and i'm heading down past that way anyway on fri. Wont be able to bolt them in till i get back sun, so expect some tuning and a dyno mid next week.
