Carrera28 Posted 13August, 2022 Report Share Posted 13August, 2022 A question for the more mechanically minded amongst the forum, this sounds a bit like snake oil to me. Does this actually do anything? https://tunersmotorsports.com/trs-development/porsche-under-drive-pulley-kit/ Quote Link to comment Share on other sites More sharing options...

JB911 Posted 13August, 2022 Report Share Posted 13August, 2022 I had problems with power steering fluid overheating on my 987 Boxster S track car, and it took an under drive pulley and an additional fluid cooler to fix the problem. I think it's only an issue with cars that are driven on track/motorkhana/etc. because of the extra work/load put on the power steering pump. I sceptical about the claimed power increase though 🙄 Raven 1 Quote Link to comment Share on other sites More sharing options...
