Yikes this took forever. Too much to do in the spring plus two ruptured discs. But back at it. Started it last night. Runs so nice and smooth. Idle vacuum is much improved. Image Unavailable, Please Login
Very happy with how this came out. Thanks to all the contributors here. It is smooth as silk, pulls like a freight train and sounds so cool. https://m.youtube.com/shorts/WtT-97E-6Ok
Mk e, In the charts the BSCF is in the low-mid 40s. It that a variable that you input or is that calculated by the program? Is it low because it’s such a small displacement engine? Would a higher BSCF result in more or less HP in the final analysis? Thanks again.
The short answer is low 40s kind of means everything is good....you're not wasting fuel. Adding more fuel than you need drops the combustion temp and reduces hp so you don't want to just add fuel. The longer answer is often a boosted street engine will end up wanting more octane than you can buy at the pump and riching the mixture to drop combustion temps and often also retarding the timing will let you run more boost and make more net hp but at some point you've added so much fuel and pulled out so much timing that you're making less hp at the higher boost setting than at a lower boost with more optimal timing and mixture. A $500 simulation software really can't predict this. I have the simulator set to assume enough octane and use optimal values. The only way to really know is to go to the dyno and try.....you add a little fuel, then a little timing , then usually it will want a little more fuel...and repeat until the hp stops going up and that is the right mixture and timing for your particular engine.
