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
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
