    Hi PROBLEM?

    Thank you for your enquiry:

    "hello just wondering if there's any benefit to running the ported blower on a l67 with,1.9 rockers,extractors,4inch alloy intake,extractors and twin 2.5 inch exhaust with 12 psi pulley?will i lose power or not gain any??"
    The smallest pulley we recommend fitting with no intercooler or cam on a healthy motor would be 10 psi. Any smaller and your AFR's would sky rocket potentially causing engine damage and a big decrease in power would result.
    The rest of the modifications you've mentioned would work great with a 10 psi pulley upgrade.

    If you have any other questions, please do not hesitate to ask.

    Kindest Regards,
    Damo

    It would certainly help but we'd really recommend installing the 25mm insulator and porting the lower intake manifold which we can help with but if you're on a budget, you can do it using a jigsaw. Please see the instructions below on page 25.

    If you have any other questions, please do not hesitate to ask.

    Kind regards,
