There is a slight chance I may have to have my sr rebuilt, after speaking to a few people some have suggested raising the comp ratio to 9:0:1 to aid off boost torque etc. What are the downsides to this, does it affect top end and make det much more likely?
I'm guessing any machine work to the block/head and mhg thickness will affect the ratio too?
I've currently got a standard bottom end with a cosworth 1.5mm mhg, I guess this has dropped my ratio?
I'm a total noob to this and don't really have much clue as you can tell so please forgive my ignorance.
