Blower RPM calculated for an engine RPM of 8500. 2. Boost is an estimate for a non intercooled/non-ported blower; Intake, exhaust, and camshaft selection will effect boost. 3. Blower heat becomes a significant problem on non-intercooled (or non-ported) blowers; running above 8 psi and is not advised. 4. Running above 12 psi regardless of setup is not advised. 5. An Endyn ported blower makes approximately 7% more boost. Click here for JRSC Calculators I've put together.

Notes:
1. LHT intercooler should reduce intake temperatures by 28-38 C / 50-70 F
2. Ambient temperature is intake temperature prior to compression.
3. Calculations based on 65% Adiabatic Efficiency for 8 psi and below.
4. Calculations based on 60% Adiabatic Efficiency for 10 psi and 55 for 12 psi.
