Getting 375rwhp is not that hard n/a.......it's just hard when you're talking about bolt-ons You can easily make that power if you rebuild the engine for more displacement and higher compression. The stock 4.6 3V's compression is not very high to allow us to use 87 octane fuel.
A 5.0L stroker block with pistons set-up for 11:1 compression and those same stage II heads and cams will definitely get you to your goal of over 375rwhp.

Way more power in forced induction, you cant reach that level naturally aspirated.
What kind of racing?
Circle Track?

You should be fine with that setup. The twin screws have more heat soak because they sit on top of the motor! Centifugal should have less heat soak, should work well for that application.
Thos power levels are fine with this engine. I have 450+ RWHP and mine runs great and have pushed it hard.

I am starting to think this Procharger would be a better idea than N/A, since 425-450RWHP is about perfect for road-courses in my opinion, any more is not going to be very helpful. Since it is so cheap (compared to other blowers) it would give me more money for the suspension. So an intercooled centrifugal should be fine then i guess heat-wise.

So this is for auto-x? I would a S/C is almost a must for when you race road courses. That and thousands of dollars sunk into the suspension.

For road courses, i go to a lot of track days and want my car to be at its best. The suspension has for the most part not a stock part left. What i am trying to decide is if i should go for around 375RWHP and then get nitrous for the strip when i go there, or just a Centri-SC, i am starting to think the S/C is the better option of the two, since it will save me some money, and might perform better. My concern was the S/C overheating, but with an intercooler centrifugal, it seems like that isn't an issue.

Looking at the cost of the centri S/C and my needs, it seems to be what i should do, even though i kind of wanted to build up a 4.6, i think in the end the centrifugal will be better. Thanks for your help.

I got a JLT CAI Series 3 110mm, CAI, 65mm GT5OO TB, Comp Cams, Comp. LT Super Hooker headers, O/R X pipe, ST3 Hi flow CNC Ported Trick Flow Heads, and a Stroker kit and 4.56 gears soon. I plan on trying to make a N/A beast with a compression of hopefully 10.34:1 maybe try and make it run on 91Oct with a little bit of nitrous. a build with a little over 23 grand under the hood
