JRSC and CRV crank pulley gain PSI ?

I heard that by replacing the B18 Crank pulley to the CRV B20 crank pulley and you will boost 10 PSI instead of the stock boost that comes with the JRSC which is 8 PSI i'm not sure???any info will be appreciated. thanks

ya my buddy had a b20 with type r head with JRSC and some tuning, he was able to get a 15psi spike while tuning, so they limited it to 9psi

That doesn't add up. eaton blowers don't spike. A b20 crank pulley, and stock alt. and blower pulleys will give you around 8-9 psi. If he had aftermarket cams, or really poor cam timing it could create useless overboost.
