i use to be able to listen for timing but with my new mounts i cant hear nothing,,,,,,,,what are my options to test for ping so i can advance tiiming and still be safe
running 440injector now
Well as you might know the afr helps to cool down the combustion chamber, so running lean with to much advance and boost can be dangerous.
I look for small little puffs when doing dyno pulls.
Another good way to find the sweet spot is to run some 100 octane, retard the timing a bit and walk it up until the power starts to just drop off.
Once it just starts to drop, back off a few and call it a day.
I go with 2-3 degree increments.
This is not for the butt dyno.
50/50 water methanol injection will allow you to run max boost and timing on pump gas, works great.
I time G60's per the factory specs, unless I'm squeezing juice or running mega boost on pump gas.
Then you can back it off a few.
I'm certainly no guru engine tuner, just my personal experience so I thought I'd share.
