Just got back from the dyno, it Made 288WHP and 288WTQ on pump gas at 17 degrees of timing (on a mustang dyno witch is about 30WHP and WTQ LOWER than a dynojet so lets just call it (320 lol). I'm pretty happy with the results but im aiming for 350 so I can sleep at night. I know everyone is going to say E85 but its a 20min drive and don't want the hassle of it all.
So first off im pushing the limits of my LQ4 MAF, im at about 11,300hz at the highest. Based on my research I can do an AFC but is there any downfalls? How do I tune for that? Theres a fixed one from ZZP looks simple to use, any thoughts? Im running a 3.0 pulley at 10.5PSI with no signs of real knock.
Secondly, 17 degrees is the most timing I could add without my WTQ dropping substantially. I found this disappointing as a see people run a ton of timing on these motors. I have tiny blips of kr but nothing over .5 (second gear pull). All my AFR's are dialed in.
Lastly, I just ordered a water/meth kit from AEM. Since I don't have the luxury of E85 I want to squeeze every HP i can out of this thing without having to go turbo. I know how difficult that is with all the parasitic loss of these blowers.
Any advice to help me get to that 350 mark would be greatly appreciated.
