[QUOTE="MG0h3, post: 15887636, member: 164690"] Either would help in the torque dept. E85 because of the extra timing. Pulley brings more boost on way earlier. On my 2.9 with a 3.75 pulley, Wot from 2500 or so would give me 12-13 psi and it would crawl to 15 by 4K or so. With a 2.9 upper pulley I get 10psi at half throttle just passing someone on the freeway. Not sure it the motor or the fuel is the limiting factor in the case of the 550 here.
