It doesnt always knock but it does worry me. I am selling things in parts for sale so that i can get a safc II this week. I really hope to get to low 13's at 10 psi...then it would be a rocket ship

Not exactly lol, but good run

you might be getting heat soak. if you have the stock sidemounts. you can only do one run at a time and have to let it cool off. what is your iat temps? higher the heat temps easier the knock.

its a 10:1 motor. Hes running no fuel control and the TT ecu thinks its playing with a 8:1. I would take the PSI down a notch untill you get some fuel control. Then look into some meth you'll pull numbers there also.

Get some fuel control SAFC2 for basic tuning.. Emanage blue to really get the fuel tuned out or emanage ultimate or other piggy back/standalones that will control timing are your step up from that.

There could be lots of reasons your seeing knock. lots...

I'm getting more knock than you running wastegate pressure and stock fuel. I'd check your fuel pressure to make sure it is sufficient. I'm thinking of hotwiring my fuel pump to see if that will get rid of my knock, as mine is definitely from running lean. I bet yours is too.

Fbc 978 · 04-20-2008, 06:20 PM

hmm how do I check the pressure...im running a tt fpr...maybe I should upgrade to a walbro fp.

Just put a fuel pressure gauge in between one of the connections for the fuel hard line. You can do it yourself with the correct fittings. 3sx sells a complete one with an adapter and it's not overpriced.
