Re: Cams
I depends on your "same setup". Stock - you wouldn't be able to measue the difference. If you are running a medium build and higher boost and need to run a little higher rpm then it may have a slight advantage. A higher built motor running 5,800 - 6,000 rpm and 23+ lbs of boost then it would be worth it. The 114 lobe separation in the 422 cam helps control the intake/exhaust loads of higher boost levels.
Turbo motors mask a lot of cam differences. It's is not as critical to have the perfect cam on a turbo motor like a NA setup. I have run my 412 cam into the tens and basically gained zip when I changed to the 422. I did notice that I pulled better at the big end with the 422 as the 412 setup nosed over a little at the end of the 1/4. What I gained there I thought I lost a little on the short side. The times were no better than a tenth or two. That was running 26-28 lbs boost and 5,800 -5,900 rpm runs with 72GTQ turbo.
I would stay with the 412 or the 415 on any stockish to mild build as there are many very good tuning setups for these. If you are going to a more agressive higher boost build then go with the 422 and get a good tune setup for it. If you already have a 412 in your motor, it's not worth the change until you decide you are going to push it with a 70mm or bigger turbo and want to move the rpms up to the 5,800 - 6,000 range.
