    Default boost vs static comp guide??

    I dunno, say I'm 9 to 1 alum heads. 10 LBS? I know there are tons of variables, I'm just wondering what would be the limit of boost for something like I've got? Pump gas wise, For me that's 91 octaine. I'm kinda thinkin I only need 1 turbo, like 10 lbs. of boost?? I'm one lost mofo,.. seriously.

    I am going to suggest less boost may give you a better chance of not burning holes in the pistons with pump gas, but I don't know what type of turbo system you are going to come up with. Better plan on at least using an A/F meter to set it up if you can't afford dyno time.

    A little 106 mm 1.50 housing and 12-13lbs should work ok.

    If you're serious, I have a complete Race Arrow setup with wastegates that will get you to 15+ easily.

    9:1 compression,10lbs of boost, 91 octane will put holes in the pistons and ruin alot of parts. Go for it if you use good fuel, 100 octane or better.

    You could pull it off if you take some compression out of it, say 8:1

    I would use the RACEARROW set up over the Banks system. Just my opinon.
    Good Luck!

    Right now I'm broke, but I wouldn't mind seeing a pic or 2. I'm just thinking out loud, thought I'd start to keep an eye open for a deal.

    I have no idea on the arrow or banks stuff but we run 12-15 on pump all the time on blowthrough. 1000hp and change.

    8:1 compression you can safely run 10-12lbs on 91 octane.

    You should be able to run a couple of pounds of boost more due to the elevation.

    Oh yes, Marv has always been known as a very shy guy. He has been this way since he was very young. If you guys need some good info, just ask him and maybe we'll be able to pull him out of his shell.

    Good to see ya here marv.
