    Default 03 mach1 with ysi blower/pulley question

    im upgrading to a ysi trim om my 03 mach1. i have 8 rid setup and an I/W 10% overdriven crank pulley. i want to be around 700rwhp or more without belt slip and without replacing belts all the time. what size blower pulley should i use to achieve this? and can i use a standard vortech blower pulley or do i have to get a R/R ultra grip pulley? thanks for any info.

    I'd say a 3.4-3.2 rr ultragrip pulley should get u where u wanna be. Says stock block in your sig I'm guessin its been built at this point.

    I wouldn't think the intercooler would cause u to lose boost especially since it will be cooling the air charge. You don't wanna go too small on sc pulley it will put u at a higher risk for belt slip. I would do a 3.2 at smallest and some kind of aftermarket tensioner so u don't break it and so it can help u with any slippage as well.

    You do loase boost pressure with intercooling. It is 100% normal. Cooling the intake charge will allow for less back pressure, because colder air can be compressed more, therefore, the compressor is not compressing as much.

    People who see more boost on cold days, need to double check. You should see more boost on hotter days. Hotter air cannot compress in the same volume area, therefore, more back pressure(boost) is created.

    Should have numbers soon, I am hoping to tune again sometime next week. Build details below, very similar to your project.

    03 Mach 1
    stroker 5.0
    9.7 compression
    stage 3 heads
    Comp stage 2 cams
    SHM ported intake
    Accufab twin 60 TB
    Kooks 1 5/8" x 1 3/4" x 3" collectors
    YSI
    3.10 pulley
    IW 10% overdrive balancer

    Pulled to 5,000 rpm and made 12psi, I figure the set up should continue building power to ~ 6,600-6,800 with a total boost of 18-20 psi.
