Any one running a 228R cam with 112LSA and a turbo, if so how do they like hit? Would it hurt performance being turboed over a stock cam?

ive always been a fun of running more of an 'N/A' cam in a turbo app because i have yet to see a so called 'N/A' cam not do well under boost. if you make good power n/a, add approx 30hp for every psi you plan on running.
my car made 380 before the turbo. then i added 9psi and according to the 30hp/psi it should be around 650, it made 630 which is pretty darn close considering thats a VERY rough estimate. (the cam only numbers were also through a ten bolt, the turbo numbers were through a 9in.. same dyno for both though)
this also why you hear people say just run the cam you have, if you already have one.
id go 228R, it has a better power band than the MS3

it will bleed some boost, but if anything itll just help the motor survive a lil longer haha.

Try running a TSP giant under boost. It will make power but it's not a good cam for boost, yet it runs like crazy N/A and on spray. You will find the more you turn up the boost on a more N/A style cam it will lose more power compared to a correctly spec's turbo cam.
i was more referring to those of us who go from h/c to turbo and that we shouldnt really shy away from n/a cams at that level because its not really worth the effort. the car is gonna make more than enough power.
when going through the hassle of building a motor, by all means get a turbo cam spec'd

that cam is not perfect for boost, but it does a damn good job. i used it with my d1 and 346 and made great power. its also a great DD N/A. mine was 114lsa though. 393rwhp NA before better fuel and UD pulley.
35thcamaross is another guy i know with boost and that cam. and no probs with that cam at all.

Not so. There are guys here pushing crazy amounts of boost on these stock motors and were not talking about one or two guys. If there are guys who are running minimal amounts of boost its because they are afraid to turn it up to break something but we all know if the tune is right it will live. So put in a good cam, turn up the boost and have fun.

I am running a 224/228@114. Have yet to get it on the dyno, but am in to see others results as well.
***Edit... Just checked the pics from my build and I was mistaken. Its 224/230@114. Comp cams XER273HR-14***
