Race Developments UK picks up ~100 horsepower with their Audi 2.5 TFSI cylinder head work on a MKIII/8S TT-RS - Before and after dyno

These are monster gains for cylinder head work only at this output level. AudiBoost asked Race Developments if this included any camshaft work and they stated they do not mess with the cams even for 1000+ horsepower builds.
The head is ported and likely milled. Whatever their recipe is we do not know but it clearly pays dividends:
Talk about a huge increase in flow up top! Power goes from 364.58 hp to 465.33 hp without any other changes other than the Race Developments head.

#audi #ttrs #8s. Engine we built a few weeks ago. Same turbo and same boost pressure. Solid 100bhp gains with increased spool too. Mapper was lost for words. Customer over the moon
AudiBoost is at a loss for words as well.
