Compound charging

  1. Feb 13, 2014 #1
    Hi, I am currently seeking advice and looking into the idea of compound charging with two turbos. One blowing into another.
    Here is a basic article on the subject.

    I am currently running a single turbo setup with methanol injection on a 2.7 liter inline 6. I know the benefits of having a smaller turbo and a large turbo would be having the efficiency of both with out one running out of steam so to speak.
    Now is this a plausible way to have a better power curve at lower boost such as 20psi? I am at 15psi currently, my ignition system is limiting this, but with new turbos will come a wasted spark setup.
    Having some experience with this engine, it made quite a bit of peak power with a gt35 turbonetics on a different car(same motor but 2.5l). However it had a lot of lag and wasnt the greatest to drive around town. What I am chasing is the top end of a bigger turbo with the kick of a lower turbo.

    Any thoughts on this at all? Im reading Corky Bell's Maximum boost again, Ive been thinking aobut contacting him if its even possible to ask him questions.

    Turbos have come such a long way that there is almost no need for it except for usage on small cubic inch engines that make insane horsepower.

    I'm talking about 1000+hp 2 liter Mitsubishi engines and such.
