    Do you plan to or are you running an ignition timing controller? I ran an MSD 7AL3, it had a multi-step timing retard feature for each stage of n2o.
    i just run the timing 4degrees less.

    As a general rule of thumb, 1.5 degrees of ignition retard for every 50 HP of n2o is common.

    I have a friend who swears by it. He runs it on a 496ci chevy with a 10:71 and 18psi. I am pretty sure he is making 900+hp in his 19.5 Schiada.

    I run 91 octane in my engine. I ran some nitrous (175hp) a while back and I bumped up the octane for that. I ran vp 100 octane.

    No, I loved it. Its all still on there and ready to rock.If possible, Ill have an engine built for alot of nos next go round. I think a 500 shot on the river would be hard to beat.
