I have a 04 xr6t auto it has the following mods: 60lb injectors, walbro 255, valve springs, monza cooler, knn filter, 3.5" dump, hi flow metal cat. Car made 292rwkw on 13 psi. My end goal is 300kw+ No more than 350 it's just a daily. Well my fuel pump is on the fritz and needs to be replaced thinking a walbro 460. good time to consider e85.. I love the benefits that e85 offers and it would surely push me past that 300 mark I've been aiming for many years. Filling up more often doesn't worry me I can get e85 5 mins from home. But what are the cons of e85? Short term & long term..
