    Your insulators have been sent off, so you don't have much longer to wait :)

    As i am interested in getting the 12mm manifold spacers for my 07 VE SV6,
    would be interesting if you could post your pre/post install temperatures from your scientific studies and any 'seat of your pants' feelings about pre/post install power/torque gains, throttle response and fuel economies.

    Yep I'll be posting up my findings , as in temp before , start up , and after a drive of a set distance , and the after fitting , go for the same drive at the same time of day , or similar conditions , and see what difference they make , having said that , on my old VX , which has 12mm manifold insulators , you could feel the difference by touching the top of the plenum . So with the 25mm insulators , I would expect a greater drop in temp .

    commodore665 has very generously come up with some findings here.

    Hope this helps.

    Hey guys, bit off topic but was wondering when i put the manifold insulator on today i obviously use the gasket sealant. Says after 1 hour to tighten it fully (only finger tight for first hour) after that am i able to drive or do i need to wait the full 24 hours?

    when I did mine , I used some copper gasket cement from a can, Iv'e still got the RTV sealant Mace sent , and pretty much just let it go tacky for a few minutes , and it was good to go .
    Went a quick drive after install , out into the country , luckily only about 5 minutes from here is rolling farm land , and open road limits as well . All good .

    So you just used the copper gasket spray no RTV sealant? is it still a goo substance from the can or just a spray?

    Sounds like the place to drive :)

    we have a few mountains about 10 minutes away which makes for some spirited driving ;)

    Other question would be did anyone use the original gasket as well or chucked it out and used the insulator? any clearance issues? Just paranoid about a vacuum leak possibly happening only using a spray :/

    We normally recommend discarding the factory plenum to runner gaskets on the Alloytec when installing our manifold insulators. The reason for this is because including the gaskets, if they're second hand, can increase the likelihood of a vacuum leak.

    If you have any questions please don't hesitate to ask

    Kindest Regards,
    Steve

    Are you still doing VE Alloytec tunes? I have a quad tip exhaust, 12mm manifold insulators, and just about to put in an Orssom OTR. Would like a tune as it's using a heap more fuel now...
