    on the fuel economy thing I can gauntee a worked holden engine is absolutely fucked and on that principle alone If I was building a engine now it would be LS every day of the week

     

    not ot only is a Holden 3 times more expensive to get decent power they are then 2 times more expensive to run once you are done

    That’s my thoughts to cava

     

    iv had my hand under my bypass valve and giving it a hard sharp rev and doin only sees A couple psi and bearly makes a noise when doin that compared to when driving and it actually builds up boost in the pipes

     

    the old v2 blower use to do big woooosh should, now with v7 it’s more a sharp hard crack noise like a whip noise

     

    i can can tell you that is a lot of air that comes out, so much it’s had me concerned if it would blow my plastic radiator shroud Into the radiator one day

     

    infact its so much I have actually wondered if it would physically be able to travel down a 2 inch pipe of any distance like 600mm to the  intake or 2 metres to the exhaust with out having back pressure issues

     

    grp A ute please let me know how it does go and if it gets any flutter noises at all as I’m very interested to know, never seen them actually plumbed back in but have heard it is a legal requirement

    Are yep

     

    iv wondered if it creates pressure flutter when it goes of when plumbed into air filter

     

    a massive amount of air comes out at high rpm

     

    i actually thought its ment to be plumbed into exhaust system but not sure that’s just what I thought

    Yeah i thought about that

    <span style=”line-height: 1.5;”> </span>

    <span style=”line-height: 1.5;”>Personally i think the restrictive part would be the filter its self </span>

     

    My plan is to make a bit of a funnel so it scoops a lot of air into them side parts

     

    I wouldnt make a full air box down in there especially using the inside of bumpa as a side of it

     

    Doin  250km/h backing off i think it would probley blow that side of front end off its mounts

    Yeah I just bodgied this up out of fibre glass

     

    I just st made it out of cardboard and sticky tape then glassed over it

     

    about 2 hours later glass was strong enough to hold its shape but allowed me to remove cardboard then I had a skeleton out of fibreglass to work from, had to cut a big chunk out of side as I have pipe work there

     

    also wacked a bolt through it all to hold air filter in place so it has 20-25mm clearance the whole way around it</p>

    Sean though you built this car with not much left unmodifyed on it

     

    why dont you take them adapters and throw them in the bin

     

    then set set up the fuel rails to sit lower onto the 3/4 length injectors ??

     

    Or you you can just keep going and anodise them and I will just be quite

    Either of them

     

    irs7 say they come in 18 but don’t have details if they come in 10 inch or not so finding out as I kinda like them

     

    if anyone knows other films that come in either 8 or 8.5 inch for front and 10 inch rear and must be 18inchs and must be big brake compatable

    Was only able to get about 73 L with dual exhaust

     

    myn goes all the way up to chassis rail at back of diff and all the way to back rail

     

    to to remove harrop diff cover would be either a diff removal or tank removal

     

    tank removal in myn is very easy
