Plus make sure that your intake mod doesn't end up a "K&N hot engine bay intake" mod, as this will make SC heat issues substantially worse. SC needs cold air intake, especially if you increase boost with a pulley mod.

Intake mod is a waste if all you are going to do is pulley and a tune. People tried this already, no gains in power. Considering that it is hidden from view, you won't even get the look.

I'll be doing it for primarily sound reasons, to remove resinators.

F-type uses Eaton TVS R1320 on the V6, and TVS R1900 on the V8.
You can port and polish for a better flow and coat rotor for better thermal protection.
Doing some web search on porting Eaton TVS, it seems like a mixed bag. By itself, without any other tunes it should reduce SC power consumption. However, potentially, when done with other porting and mods it could help safely increase boost.

Also, sts-v, make sure you are aware that F-type does not warn you of low engine oil conditions. Considering that tuned car is more likely to experience blow-by when pushed, I recommend you a) install catch can and check it b) check engine oil level regularly c) change your engine oil a lot more often than factory schedule.

I believe a couple have, and they've been safe so far. I haven't because you destroy the upper pulley in the process of installing the new one and I like to have the ability to return to stock.
Something to keep in mind on this platform compared to your Cadillac is that we will never have the amount of aftermarket support you're used to. So far we've only had one person in the tens and he had to port the S/C and add nitrous/drag slicks to get there; on top of full VAP mods. Outside of that myself and another AWD R member have been the closest at 11.3X. The other member claims to have been stock but haven't seen him around much.
Ive constantly (albeit slowly) been working with VAP to fine tune my engine and try to get to that 10.9 mark. But have constantly been running into little issues such as grip level and cat temps that have prevented me from getting any closer.

Talked to stuart - dunno if I should do both the crank and supercharger pulley.
Car makes 15psi boost on the stock pulleys. Supercharger pulley adds 1.5psi. Crank pulley 3.5psi. At 20psi starting to run the blower at a speed the is right on the limit of the efficiency range.
he advises picking one or the other because 20PSI will require 100% functioning of coil packs, injectors & plugs and in high temperature environments even then intermittent misfires are possible due to heat soak unless you upgrade the charge cooling system - which isnt available yet to my knowledge

I prefer to build constant power, all time gains with no hassle (same reason I dont use NOS.) But if you were considering, I'd do E85, then meth, then nitrous in that order.
