Boost vs Fuel Enrichment?

Post  AlkyPinto on December 3rd 2011, 12:08 pm

Are there any formulas out there for how much the fuel system
needs to be enriched for each lb of boost applied? And more
specifically, to maintain the correct A/F ratio for E85?

I'm not aware of a formula, but I know on Dry NOS setups, we typically start with 30pph of fuel per 100HP of NOS consumed. If you know the brake specific/est hp, you can calculate how much fuel you need. Ex. on Gas, 1000HP (boosted) may run @ a BSFC of .6 One would need 600pph of fuel. Add 30% for E85..I've been told that a boosted engine can pick up 7% HP per pound of boost. Not sure if this is accurate. I'll keep my eyes open, and if I see a chart for boost, I'll share.
