The warranty on my Roush Phase 2 supercharged 2018 GT is set to expire. Now time for some power upgrades! I am working with an experienced and reputable shop / tuner and we have put the following mods together. Curious if others have swapped the pulley on their 2018 or newer Roush blowers and what power results they achieved. Would welcome any other thoughts. I am not one to be penny wise and pound foolish. Car has been lowered, has 305 Nittos DRs on rear, and runs great.
Here's the list:
- VMP 2.8" pulley, possibly smaller belt (to be evaluated)
- one-piece 3.5" aluminum driveshaft (DSS FDSH53-A)
- VMP boost-a-pump
- Billet oil pump and timing gear (apparently this is a 17 hour job but strongly advised for the Gen III Coyote at these power levels)
- Long-tube headers (likely Kooks or Stainless Works)
- Custom dyno tune - baseline and after mods
- Half-shafts - we discussed and decided to pass for now. If the car is not being tracked heavily / frequently and not many hard launches (i.e., mostly spirited driving), tech said the half-shafts should be fine. Said he's seen many others at 800-900 HP on stock half-shafts with no issues.
Thanks for the input.
