If you are talking 450 crank HP (which, I am not sure why you would want to), you would need to mod to approximately 369 RWHP which is achievable but not with the mods you described.
see ImportLabSRT... He currently has 506RWHP...but then again, his SRT is boosted...with a turbocharger...so I guess he doesn't count.
I agree that I do not believe anyone has even hit the 400RWHP point with the stock SRT supercharger... If only there was room for long tube headers on this baby.
