Dinan/RMS Vortech Stage 2 Boost level/Pulley size = HP levels?
Trying to get an idea of how much boost I need to run to make certain horsepower levels. I'm looking at my NASA Time Trial rules and have to fit into certain power to weight targets depending on which class I want to run in.
NASA uses an average horsepower at the wheels measurement, taken from a Dynojet. For my car it's the peak HP, and then the next 5 highest values at 250rpm increments. For TT4, I can have an average of more than 290rwhp. Next class up is no more than an average of 355rwhp. My car has all the bolt ons, including Schrick 264/256 cams.
Can anyone give me an idea of how much boost I should run to hit those horsepower targets, as well as what pulley sizes I need? I have the RMS 6" crank pulley, so really I just need to know what blower pulley sizes I should be running.
Posting up some dynos showing how much power you've made with what mods/boost levels would be very helpful for me to ballpark where my average will end up as well.
TIA!
