  1. its best to wrap the manifold, having a wrapped manifold reduces under bonnet temps, but will also stabilise the heat up and cool down of the manifold

    reducing the potential for cracked manifolds

    the worst manifolds for cracking are stainless steel, as in the polished type, most peeps use

    ...and not to forget: Heat wrap raises exhaust gas temp. which raises exhaust gas speed,

    for better spool up.

    Who knows physics will know, that the hotter gases are, the thinner they are so the quicker they can flow.

    :winky:

    Same on exhaust system..... a too big diameter in exhaust system can reduce power instead of

    raise it.

    Exhaust gases can cool down because of the lower speed in a large diameter ex.sys.

    and cooled down gases reduce speed and can block the gas flow. ;)

  2. Thanks for the offer Mike but I've already got most of the 3" system already fitted. Just need the bigger decat pipe and cat back exhaust.

    Plus I need it ASAP as I've 'sold' the Kazama months ago. Also the new down pipe and other section has pushed the Kazama up slightly and it was touching the TTE rear lip and started to get it a bit too warm

    Ah I see.... OK! :winky:

    Pics, pics, pics when you have done the job mate! B)

  3. YYOOOOOO SO GLAD TO HEAR THOSE GREAT NEWS BUD!!! :winky:

    Did you notice a difference in exhaust note since the lower CR with the new internals?

    Ordinary you also should have a bit more than 2.0L of displacement now. B)

    So happy that the car is running now!

    Let us know what's going on with the mapping session you start soon. :whistling:

    Congrats,

    Mike :winky:

  4. Mate pls upgrade your injectors!! :o

    To add an extra injector can help but it isn't the best solution.... some cylinders can get more and some can get less fuel, so overheat can be effected in single cylinders and you wouldn't notice on your ex.temp.gauge. :o

    I think it would be OK for those 0.5-0.6bar, but when you plan to reach 1.2bar,

    do us a favour and go for bigger injectors to replace the extra one. :winky:

  5. Fair play to you Adie - a "belt and braces" job :D

    As your car is (or will be) probably one of the most powerful around (except for a guy in Norway) with the 1G FE engine, I don't think anyone knows for sure whether you need the fuel return line or not. Better safe than sorry though I guess :)

    All my thumbs are up for that project!! :winky:

  6. WOW! B)

    That looks amazing!

    Top Job!

    But I'm wondering how the traction on the IS will do with +1000HP :whistling:

    Maybe a serious launch control system will help. B)

    Traction in any car with 1000+HP is an issue but I am upgrading my diff to a ford 9-inch with a 4-link coil overs set up and will be running either 315 or 325 series rubber on the back so traction will be pretty good.

    That's an idea.

    A good launch should be possible then. B)

    But take care on wet ground, the IS body is pretty light at the rear axle, at all the

    weight ratio (front/rear) will take some differenced caused by the heavy engine in the front.

    A 325 rubber will show its effect during hard braking and on wet streets. :shutit:

    But I guess.... a car this like won't see wet streets, just drag strips. :D
