My build, can I reach 600rwhp?
is the power ur talking about came from the BC STG III cams, ????
or the Math + extra timing in the ignition map ????
what about if we have the same setup with the JWT C2 cams ??
So as someone mentioned before, If my injectors are rated at 650 at 3 bar, right now I'm running about 52psi (stock psi) right now, so that's almost 4 bar so like 750cc as someone mentioned previously. Wouldn't that be sufficient for my power goal?
BC stage 2 cams you can just drop right in. No spring or retainer upgrade. With most other cams you will need to upgrade those parts, at least.
By "best" do you mean best mix of power and calm idle? Or 100% power? Power where, up top? You see the point...
It really depends on what you consider "best"

my heads setup is, C2 cams , JWT springs and shims, SGP TI retiners, and Brain crower stock size valves.
those days ppl just talking about BC and GTM cams in FI Forums.
makes me feel like i did a wrong decision chosing JWT C2 cams
better to get the CJM twin pumps.
Like Fluid1 said... It depends on what your application is and what your priorities are in determining what's the best cam for you.
There is no single answer for what's the best cam to make 600whp either. It depends on what your turbo setup is. For example, a large single turbo setup like the PowerLab GT37R doesn't even need aftermarket cams to reach 600whp. A single turbo setup produces more top end power, while a twin turbo setup produces more midrange power.
The reason you're hearing so much about the BC stage 2 and stage 3 cams lately is because they seem to shine at making top end power on twin turbo setups. This is something that a lot of twin turbo FI guys have been looking and waiting for. BC cams have shown in Julian/MRC's reviews and on SP's 1,033whp shop car to make power beyond 6500RPM. The first cams I noticed making power above 7000RPM were the BC stage 2 cams, when Julian posted his review. SP is making power with these cams to 8400RPM.
The BC cams are great if you have a twin turbo setup and your priority is top end power. There is nothing wrong with JWT cams or the other brands. As Alberto has posted in his thread, the JWT S1 cams are great if you want nasty midrange power. If you want stock idle quality without having to adjust idle and/or want more low to midrange power, than big top end biased cams aren't for you. Up to this point though, the BC cams are the only brand that have been shown consistently to make power up to 6500RPM and beyond.
Another interesting fact that should be noted is that all 3 members of the 1,000whp club (Injected, SP, and Intense) are using BC stage 2 cams in their shop cars.
All this being said... For the OP's standard APS setup and 600whp goal, I'd recommend the BC stage 2 cams. The stage 2 still has decent idle quality and it won't sacrifice a lot of low to midrange power. If you want to make big numbers with a smaller twin setup, a cam with good top end performance like the BC cams will be essential to achieve your power goals.

The BC stage 3 cams are optimized for top end power for the guys that want to make high rev peak power their 1st priority. They also seem to make a more linear power band on twin turbo setups, which helps with traction on the bottom half of the powerband. Alberto indicated in his thread that he is hooking up better on the bottom end with these cams.
tomei makes more than jsut 1 set of cams..which one you have?
your engine building should have specified this to you already
Thanks.

) and the Stage 3's would be better for guys with the Greddy kit, which is a fast(er) spooling setup. I guess the other issue is the idle, which some people don't want to compromise on.
Interesting. It would seem to me that the Stage 2's would be better for the big ST guys ( I have two in mind ) and the Stage 3's would be better for guys with the Greddy kit, which is a fast(er) spooling setup. I guess the other issue is the idle, which some people don't want to compromise on.

I bought BC stage 2 cams for my motor build, but then a fully built longblock that is virtually new recently became available and I jumped on that opportunity. This motor has Nismo cams in it. The specs are almost identical to the BC stage 2 (the only difference being that the Nismo has 262 duration and the BC stage 2 has 264; both have the same lift). So I'm gonna see how it performs with the Nismo cams. If I'm not satisfied, I'll replace them with the BC stage 2.
My guess is that your Tomei cams are either the 256, 264 or 272 version. The 280 cam by Tomei is their newest one and I haven't heard of anyone on the forums here running these besides the Intense widebody G that ran them for a short time period before replacing them with BC stage 2 cams.
For comparison, the BC stage 2 is 264 duration and the stage 3 is 272. Both BC cams have higher lift than the Tomei cams.
Here's the links with the specs:
