    I had to search 'turbo' and 'non-turbo' and refine it to title only.

    Needless to say 98% of the posts were in video suggestions but then i found this one.
    It was way at the bottom which was one of the reasons i decided to bump it.
    Ah.
    Well, good that you did.. Maybe I should have tagged it better..?

    Sure, go ahead.

    Good job searching, was it easy to find?

    I tried, but they don't want a forest of stickies at the top of the forum, so that probably isn't going to happen..

    You can always do things the good old fashioned way and install a rising rate FPR until you can properly tune the car

    Actually I've known some people to run off a RRFPR only... its generally the euro community who have bosch DME III and under as they didn't use a crank sensor (meaning the MS conversion is harder)

    Its not the most efficient way of tuning but you can usually get your AFR to stay out of the danger to manifold zone

    In a perfect world it would be true, but unfortunately it isn't meaning you can never get that efficiency. An Awesome write up though

    This should be stickied to prevent newcomers to the forum from starting their own thread in regards to this. Not many of them use the so-called search function.

    In reality, things might indeed not work out so well, a poorly functioning intercooler, having to reduce mechanical compression and timing all kill off a lot of power, but hey, thats where tuning in the true meaning of the word comes in, improving those things so you do get the power. Also, if the mechanical compression was quite low to start with and no reduction is required for the desired boost level, the power gain might be bigger than expected indeed..

    Yeah, I guess you are right, but as an order-of-magnitude rule of thumb, it probably works still works?
    No need to run 2 bar of boost to get only 50% increase, or vice versa..


    Exactly.


    Yeah, way easy indeed.
    Also, thats why I recommended swapping in a complete turbo engine if one is availible..
    Different turbos have different cfms, and therefore more or less power at the same psi. But the double fuel/air= double power makes sense. At least with the low boost you would run on an N/A, as there are diminishing returns.

    But awesome write up. +1 indeed

    I always recommend the book "Maximum Boost" by Corky Bell. It helped me get started on building my own turbocharged vehicle. This led to me building another 25. Cost me too much money and 3 girlfriends. Now I get paid to design and build turbo engines.

    Just keep that in mind. Everything else looks good.
