i seen the roots blower intercooler kit does anyone know the price and the gain from just a regular JRSC ?

I have seen it also......As for the specs? I had the jrsc for about 9 months..I have seen better gains with the stg2 cams and head work..jrsc just kinda hangs here in the garage right now..Just cannot get enough psi even with a pulley to get better gains. In a nut shell the charger is just not big enough
