Magnuson2650 Pulley combo
A question for who ever went throught the trouble of trying diff type of lower+upper pulley set ups, i am going with a vvt1 *stage1* cam 32% fuel lobe, dsx low side and a jms volt booster and meth for the fueling, i have been wondering if i could go 85mm upper and 9.17 lower with this fueling support? or if anyone tried another setup of pulleys and finds it great I’d appreciate the recommendation i am really lost.

With your fuel mods plus a LPE HPFP and +30’s but no meth I was out of fuel on E50 with a 9.06 lower and 85 upper. Making 18psi. This is a heads/cam 11:1 compression setup though.

My tuner said i can go 85mm with 9.17 lower, but i doubted it i think it makes more sense now that its impossible to do so, i am running 13.9 psi now with 85mm and stock lower with meth only, the rest of the mods are yet to come.

Great numbers on the stock box and TB for just a lower pulley, longtubes and tune. How was the heat soak with the longtubes added but more boost? |

I only did the dyno numbers because I went port 2 days later basically drove it over the weekend and right back to the shop for more power. Tuner said it looked fine though.
