Power loss due to WG rattel?

IncrediBrian · 05-08-2014, 04:57 PM

Anyone experience an increase in power with the new factory turbos after being replaced because of the WG rattle? The butt dyno tells me it feels stronger, but that's just the butt dyno.

Well the wastegate flaps get real loose and wobbly, which I would assume lets exhaust bypass the turbo, causing laggyness etc. The last car I put turbos on had bad rattle, and I noticed a huge improvement afterward.

Your wastegates were not sealing, resulting in less boost in the combustion chamber. Your car will make more power with the new turbos.
