I just bought a JSRC and didnt find all the info I needed in the search engine. I had to look all over the place. Im posting this to help others.

Note: 1. To prevent slippage run POLY V belts.
2. Slightly longer belts may be used for better belt wrap on high rpm pulley combinations.

Notes:
1. 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.

6 psi 20 c / 68 f 65 c / 149 f
6 psi 30 c / 86 f 76 c / 169 f

12 psi 10 c / 50 f 103 c / 217 f
12 psi 20 c / 68 f 116 c / 240 f
12 psi 30 c / 86 f 130 c / 266 f

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.
