Per Dinan's site as I'm sure you saw, they quote 398hp/429tq vs stock 300/300. Who knows exactly... would have to dyno for that I assume.
Here is a copy of an old email I received from the Indy shop/Dinan dealer that did mine.
"Did some research and found that there are no bolt on oil coolers available for the Z4. Contacted Dinan and they stated that they do not make one and it would be completely fine to install stage 3 with just a drop in intake filter.
So this high HP jump will not require any additional components beyond a drop in air filter. Exhaust would be recommended , although not required. Tune will add an incredible 90 HP over stock and a ridiculous 110 ft lb of torque."
I did the drop in air filter but skipped the exhaust. So... sorry I guess I lied. It did require 1 other part. All told was still under $1,000 for some pretty impressive gains.
