Sadly I imagine the hardware limitation will be the turbo there... It just won't flow as much as you'd want.
Then you're into hybrids, and potentially losing the transition between the S/C & the Turbo
Interesting times though...
I think the turbo can manage that.
if its making 215hp on a standard engine with just a stage 1 remap. The main rstrictions are the induction and exhaust. If you add an air intake your looking at a potential 5-10hp. If you add the downpipe and stage 2 map your making it much freer flowing, so the turbo doesnt waste power trying to force the exhaust gases though a really restrictive system. Lets say this gives 5-10hp extra.
Alot of additional power/torque can be gained increasing the ignition timing on a forced induction motor. the limitations with this are the Air intake AIT's need to be kept low, and high octane fuel needs to be used, or you end up with detonation, knock and bent rods etc. If you add an intercooler to keep the AITs low, the stage 2 map can advance the ignition timing more releasing more Hp/Lbft.
So lets say
the the intake gives 5hp
the downpipe and stage 2 map gives 5hp
and the intercooler with map adjusted to utilize it releases another 5hp.
then were looking at 230hp. Lets be fair none of the above seems far fetched or wishful thinking in any way if anything id say thats on the conservative side.
That said 230hp is based ont eh fact that the stage 1 is giving a genuine 215hp, and not just generous rolling roads
