How much timing are you running with 9.0:1 pistons on pump?

[BIRDCLAWTSi]

I am running 9to1 pistons and can't run more than 13psi on 93. That's with 12* timing. I get audible detonation. Just curious how low of timing is safe on forged internals?

Have you verified base timing?

If you are just starting to tune it. Start at like 4-5* WOT and work your way up. With higher compression, you can't run as much timing as you normally would. Though, that seems pretty weird on a a little E316G..

Are you also sure you're not getting spark blowout? I've seen a lot of people that haven't had much experience with knock confuse the two.

I'm running a 14b now, so peak timing at 4-5* then add as much as I can incrementally? Base timing is dead nuts 5*. I've read about guys running 18-20psi on pump with 18-22* timing. I am far from that. Just wasn't sure how low I could go. I don't think spark blow out is happening, but anything is possible

I'm running 9:1 pistons in my 98 with 20 psi from a evo3 big 16g. the only tuning I have is from is a safc2. With no problems.

I did have popping out the exhaust every time I went wide open that I thought was spark blow out. It was just running real ritch. My wide band was hitting 8-9 at full boost. Leaning it out totaly stopped it and its running fine now

I was running 18-19* on pump on my 18g at 24-25 psi.

What AFR are you running?

Whats your coolant temps?

Do you have a CAI?

IDK how people hear audible detonation on their car! With solid mounts, no BS, full 3" exhaust and 35 psi boost I can't hear anything besides spool, roar and rattle!

No cai, I made a duct to put fresh air into the intake though. Have had afr from 10.5:1-11.5:1 no difference, 180* t-stat. Operating temp 199-206, wondering if my injectors are clogging up

Try running BR7ES plugs. They are non-projected.

Does your engine management log knock?
