HKS MIVEC 272/272 Cams, but what about 272/280???
As the title states, I have a qustion about running a HKS MIVEC 280 exhaust cam. I currently have HKS MIVEC 272/272. I also have stock turbo but making good horsepower https://www.evolutionm.net/forums/ev...o-92-meth.html but I want more. I was wondering if anyone has done this combo, 272/280 on the stock turbo and seen gains from just swapping out the exhaust 272 for a 280. My guess would be 5-10 more horsepower up top with maybe a bit more lag. AMS did a test like this but it was with a 35R and not very compairable. All my mods are in my sig. Lets see what what kind of talk this creates and if you have a dyno of before and after, please post. Thanks
