IIRC the factory XR6T tune specifies a 7.7 L manifold volume in the software. It's difficult to get accurate info on the volumes of the different plenums and relate it back.7.5l IIRC,Im considering taking my plenum off for painting so i spose i could measure the volume at the time,of course the volume of the lower manifold would need to be measure too, I spose the volume takes into account everywhere from behind the throttle blade to the the back of the valve?It would be interesting to see exactly what difference this would make to tuning the car? Edited 11/06/10 10:45 AM by hiddeous 7.25l actually..... Link to comment Share on other sites More sharing options...

I haven't got photos of that cos my phone died but I will get some tomoro. Link to comment Share on other sites More sharing options...

Kent (DUS12) is one of these guys. Link to comment Share on other sites More sharing options...

I read somewhere you cant buy them on there own??manifold looks cool, not sure about how the plate will sit on the round holes if you have seen the manifold pulled apart its not flush, you will know what I mean if you have seen it...are you screwing the bolts in from the bottom or top? how you gona do that? how heavy is it compared to the stocker? I kinda under estimated when I made mine I thought 3mm would be sweet....fail lol Link to comment Share on other sites More sharing options...
