So I have the opportunity to purchase a set of very nice roller rockers for my triple turbo 12v DPC build for a pretty good price, but they are 1.8, I was planning on going to roller rockers to fight rocker arm deflection anyways but in 1.6 maybe 1.7. I'm using a 194/220 cam, head flows PLENTY, and I have more than enough valve relief to accommodate the extra lift, my question is what will the higher rocker ratio do to the overall drive ability of the engine? Beings it needs to be somewhat streetable to finish well in all the events. I've got no experience messing with rocker arm ratios just looking for a little bit of advice. Thank you!
