Now that I have some time to post this, I want to know what the experts think. In my quest for 300RWHP on stock internals I came up short. So I need help.
Alright I need alot of help.
At carlisle I had Brian Herron dyno tune my car. The base pull was something like 265rwhp. After that he adjusted air fuel to perfect. He noticed that the Knock sensor was kicking in at around 3000-3500rpms and ruining my numbers. So he dicided to turn of the sensor and monitor it himself with some added timing, and he found a lot of unexplainable detonation, but I managed 275rwhp. After that pull he turned the knock sensor back on and retarded the timing so i was at a safe level. Leaving me at 268rwhp. So i am not even at stock timing, he said once I get the problem fixed he can give me more timing and should see a big increase in HP.
Now comes the problem. I have a list of fuel delivery upgrades and a MP MPIC and cannot explain why this thing is detonating. I talked to Paul from BlueT and he suggested a couple of things, ill try them this weekend. But I would like to get other opinions too.
I am making about 15~ lbs, sometimes I peg it sometimes Im at 13 of Boost. Also I have a BBK AFPR and 42lbs injectors 255lps pump and a LMAF. My understanding is that this shoud be plenty of fuel.. Plus run colder plugs and a FMIC, to cool the air down. Brian even added that My Intake charge tems were way below average because of the FMIC.
So why is it that this thing is detonating like this.
I have not touched the internal engine Yet.
Any help is appreciated and sorry for the long post.
