Race Fuel + Boost = how much timing

[rainmaker]

How much timing advance is safe with 12-14 psi?

What size turbo or blower? What (if any) intercooler? What intake manifold? What cams? Running meth injection? What ambient temp? What afr? You get the point, no one can answer that question very accurately without a WHOLE lot more information.

The correct answer is....

As much timing as the computer allows you to run.
Active knock sensors are going to be your friend.

Keep adding timing, as she wants to add timing.
Then when you see your HP gains start to slow down, then stop adding timing.

Plug reads, and watching those KR counts are going to be your friend.

talk to your tuner, and you guys come up with an educated decision on your combo

I use the same fuel for my track tune. I'm at 13psi and 23.5 degrees of timing. Runs great and never see any knock. Here is a SS of my log from when I was on the dyno the other day. The dyno bay was 95 degrees lol. Pulls were all done within 5 mins of each other. First pull they were scared and only took it too 6800 . All pulls were in 4th gear.


Row E is timing and D is my IATs.

With your maf counts pegged at 86.6 from 7400rpm to 7900rpm (column G) looks like there is no reason to rev it that high.

It's still making power, check the dyno. I have 60 logs of hitting 7800-8000. No issues but I do have a MMR timing gear and opg.

How much boost will I see going from the 3.48 to the 3.33 on my V3?

Where in NWI are you? I'm near Valpo.

I have paxton running E85 12-13 psi 20-21 degrees of timing.

Not too far, I'm in Saint John. Let me know if you ever want to hit US41 Motorplex - I practically live at the place:

Who is your tuner?

Ken Bjonnes. It was 23 but I asked him to pull couple degrees just to be in the safe side.
