I know this isnt your typical buick quesiton. I bought a Alky kit from Julio and it works fine no issues. The issue i have is i tried to use it on dyno and it sent my AFR into the 9s. Now before you suggest things in your head. My combo is a 8.8cr 4.8 LS1 style motor. I have a PT88 turbo on it, i have Motron 60s with my fuel PSI they are 73# injectors and i have a 1:1 regualtor. I tune with HPTuners and fairly decent tuner. Our motors like 11.0 AFR as Ideal anythng past 11.5 and your little to lean for safety. also some dont say to go past 22* timing, Most ppl in the LS world run 15* tops I currently run 21* on dyno. My fuel is 40% E85 60% 93. My truck made 700rwhp on a fluttering 16psi. [5psi WG spring]
now onto my issue....for those that have tuned and used Meth injection when did you realize you needed it? i know your motors are different i understand that. I have a dual nozzle kit its a M10 and M15 nozzle my meth kit was setup for my combo with use of a 408CI motor. the 4.8 is only a temp motor till i can replace my 408. I know Meth helps lower IATs but on dyno i only seen a gain of 4* of IAT temps that is no meth just thru my FMIC. I never had KR.....My question is Id love to make 800rwhp which shouldnt be too far off. I gain roughly 29rwhp for every PSI of boost. Now would you pull fuel out above 210 kpa and set the PAC to so its in use at this KPA and use meth for fueling? Im stil stock internals and dont want to hurt this motor but am greedy and would like to take use of my Alky kit.
bascially im asking how are ppl using meth and how would you do it for this build? others use meth at much less boost but my setup seems to not need it. I want more numbers since im already strongest 4.8 thats nationaly recorded and was looking to get more out of it.
