    Is there a before and after dyno chart that can be posted (there must be one or how else do people get numbers?) that will end the discussion?

    I've posted dyno sheets from 1st tune at CHE....ugly numbers but shows 20rwkw gain. This was prior to OTR and early in the tuning history. I believe the OTR and the MACE E85 tune make a vast difference. The Scanxl software indicates that it is putting out around 185+rwkw and 400nm fairly regularly. I can't say that is accurate but just telling you what I'm seeing. Here is the sheet thread http://forums.justcommodores.com.au/ve-holden-commodore-2006/155189-late-model-sv6-tuning-8.html

    I believe the title of the thread is "Working a SV6 SiDi" not "I want heaps of power tell me the best way to spend my money"

    The cost all up is approx. just over $2000, if you can find me a VE SS that will out perform my SV6 for that price I might consider a trade...
    Or maybe you are saying I should just buy a V8 engine for $2000 and leave it on the garage floor?
    Thanks for your input though :)

    Just be careful putting an OTR on a SV6. It causes a lot of dramas with the MAFF sensor.

    The ORSSOM OTR requires a tune when you fit it. MACE supplied a tune for mine no dramas.

    Fitting any OTR to a V6 or V8 will most likely cause issues with the MAF sensor, with a good tune you won't have to worry about anything!

    We've never had an OTR on an SIDI we couldn't fix 100% :)

    Reckon someone needs to start making some replacement heads for the SIDI so you can bolt up some decent extractors...
    Surely someone could sacrifice some heads, machine away the forged headers and tap some studs... then sell them as exchange and repeat the process..

    good to see some working being done on the new engines though...

    Next you need extractors and high flow cats.
    Then you might hit 250kw

    A dyno is nothing more than a tuning tool. If it says 220rwkw for example then I don't doubt it makes that power on THAT dyno.
