    Hey Guys , would like to hear some feed back from people that have fitted a 2.4 Whipple on a standard 5 ltr. I see some people reaching nearly 400 hp atw while others get only 260. Are people that have one happy with there choice or would they go a side mount second time round.

    Ok, i dont have either. But my understanding is the sidemount is cheaper, and thats it's only advantage over top mount.
    I think if procharger did one it would be a different story though.

    Depends on what you are trying to achieve.

    PD style blower (whipple) will produce bulk (tyre frying) torque almost right from idle where as the centrifugal style blower (vortech) produces boost in a linear fashion reaching peak boost at high rpm.

    There is a guy on the Commodore plus forum who's got a whipple charged 304 which might be worth checking out.

    Making good power comes down to the tune and a good fuel system to keep up with the engine, also, on a blown engine you need a good exhaust and good thermal management.

    Haven't got the positive displacement type on the 5l , it's on a ls1, and yeah low down grunt ( suitability for street use ,grunt when you want it down low is great).
    It's stock engine wise apart from that so does feel a little flat up top because of the low down torque

    Check this out , lots of money = no object , their 2300 supercharger, 355 harrop crank , Higgins ported cast iron heads and more = 813 hp @ 6950rpm @ flywheel
    Harrop in conjunction with sams performance
    Harrop have or are about to bring out a valley type 2300 for the 5l

    Between whipple and vortech theres only $500 difference.
    Trying to choose something that looks neat as and works well. Torque down low probably suits me better.
    Will definitely be looking into the Harrop one, it has never come up on any supercharger search that i have done.
    Thanks everyone

    Interesting comment (from the Harrop guy) about the crankshaft....

    You won't make the same power in the car breathing through the factory airbox!

    What everyone thoughts at first glance on this compared to Yella Terra Whipple set-up ?...In the video, is the optional intercooler pump mounted where the air-con usually is?, not an expert on how these top mount are intercooled, it would be nice to know what this set up is like on an engine not so expensive plus wonder how much boost they were running to achieve those figures. Would like to up load a pic of my engine bay but having trouble doing it

    Try using Imgur or a similar 3rd party image hosting site.

    Then, using the pic link icon (next to the smile icon at the top of your new post) paste the pic link and you're away.

    Could also try using middle red button at bottom of post ( upload a file) , although the file needs to be smaller .
    Don't know about the charge air intercooler but the optimal front mount intercooler radiator judging by mine on the v2 goes in front of all the other radiators.
    Not sure about pump.

    My immediate thoughts are the harrop would end up costing more but you'd think would be a little better, ( newer and more direct air intake), and neater looking.
    I would suggest ringing and talking to both harrop and yellow terra.

    Back in 2014 when I was trying to decide what way to go ,( it went from supercharge the V2 monaro to do the VS Maloo and ended up doing the monaro , but I rang the guys at yellow terra and talkedto them about doing the maloo and they were very helpful and informative .
    As long as done right I don't think you'd be disappointed with either.

    In a vn you won't be putting your foot flat down in 1st or 2nd without breaking/ fighting for traction.

    And in the wet you'll have no hope.

    Even in my V2 monaro, which I haven't even modded to it's potential, in damp / wet conditions I've got no hope low down in 1st and 2nd .
    Even one night, way home from work, damp, straight line ,right conditions , 3rd gear , 70 , 80 klms , probably only about 1/2 throttle , hadn't disengaged traction control and it kicked in .

    Yeah, utube , marks workshop, he's in western Australia, he posts alot of his work , explains basically what's been done and shows dyno runs and or test drives.
    Gives you an idea of what to expect.

    Took me a while, but finally got a pic up-loaded
    I have watched a lot on Marks Workshop, he seems to know what he is on about, pitty he is on the other side of the country.
    Those Harrops have got a fair bit of coin on them, plus they still have to be adapted to the car,,,, finished/bits & pieces/tuned I rekon you would be getting up near $15k

    And then don't forget the upgraded fuel system and full drivetrain to cope with all that extra power and probably a brake upgrade to help put a leash on all that power.

    Don't want to pour cold water on your plans. However, keep in mind that a powerful V8 in your car will destroy your differential and trans (if auto) or gearbox/clutch (if manual) in no time at all without being upgraded. Also you will need to upgrade your brakes - if you want to go fast, you have to be able to slow down even faster!!! Been there, done that. How is your budget looking now?

    Oops, immortality beat me to it!
