Fox How Much Timing Under Boost?

[Kpblownfox]

Just out of curiosity and for the sake of comparison, how much timing are you guys running under full boost? And how much boost?

Simple safe method. 93 octane, I pull 1* per pound of boost.
Wot NA 33* total
Wot boost 9psi 24* total.

For larger boost setups I never go below 16* total. On a sbf.

Mod motors like/need less timing.

That's where I'm at now I have 24* at 10 pounds but due to high intake Temps it pulls it down to 20* about half way into a quarter mile run. As the weather gets cooler I wanted to start adding a little more in just to see what I pick up

[a91what]

26 degrees 24 psi

Devils in the details. What fuel are you running what's your compression ratio is this turbocharged or centrifical. Stock or aftermarket block and is this with water methanol that's a lot of timing for that much boost

9:1 f1r q16 dart block. Will take more also. On pump gas it is 18 psi and 19 degrees.
