theres a plateau for everything. just saying if hes looking for the quickest spooling turbo DD, consider manifold shielding, turbo hot side shielding and the likes. this practice is ignored by many it seems. It costs 200-300 for whatever youre doing, IMO well worth the money spent if youre after top performance from your turbo.
Ive seen people trapping heat inside the downpipe post turbine. i dont understand why that would be considered a performance advantage.
