This is the key point I think for SloGN, it sounds like from his description that the fueling was not changed between the pull with pure race gas and the next pull with alky added in...that would make for a very rich mixture if the pump was working, but it doesn't sound like the AF changed much.Razor said:Lastly, the way power is made using injection is replacing fuel that is pulled. If you target a 20% replacement.. that typically is a good starting point.
You have to cut PE fueling in the chip to use alky effectively.
I've made 404 rwhp on the dyno with a GT61 turbo and stock untouched heads with alky, with your ported heads you should make around 425-440rwhp with the combo you have SloGN. Our combos are almost the same except for the heads. I've ran 7.23 at 96 in the 1/8 so your 350rwhp with a 7.6 1/8 time is a correct match hp to 1/8 time IMO. The guy's dyno is reporting the correct numbers, don't sound low to me given your times.
