What are the hp limits of the stock 951 components?

When I say "hp limits" I mean the hp level that a specific component begins to be the "weakest link" or simply can't keep up with the rest of the system.

What hp level does the stock fuel pump support reliably?

How many psi/cfm before the stock intercooler is worth upgrading?

Same question for the turbo? Manifolds?

I think the K26 turbo is the first major limitation; injectors seem to be a close second. Of course that's after chips, wastegate, boost control, tuning,... etc.

Yeah, the turbo will max out first. Actually the injectors will be maxed out a higher 3-bar FPR righ around the same place, about 265-275rwhp. I think everything else in the engine and drivetrain can handle that power-level OK.
