I have seen pics of some high HP engines in Japan (mainly), where they have run an extra water cooling pipe to cylinder 6 welsh plug, I do know that by the time the water reaches no6 it has passed all the others and would be warmer than when it enters the block, but is it worth the extra work?

guess it comes down to how hard out you are going with the engine build . eg tuning or reliablity has become an issue with #6 and this isi needed to solve it . if it aint broke dont fix it . would anyone go to the effort if it wasnt needed. what sort of engines /power have you seen it on . ive never heard of it but it is interesting

add more fuel to cyl #6 via the ecu tune

Thats all well and good, i know that is the accepted way of compensating for #6 but what concerns me is the balance of power accross the cylinders and how that effects the crank and bearings, I know that I'm splitting hairs here and if it was a great way to fix #6 alot more ppl would be doing it.

^^ i think more to the point if it was required, everyone would be doing it.

But its not, 400rwkw, motors don't even have a sniff of issues, even bigger power ones.

I mean if these big big budget motors/setups dont feel the need to spend what would be classified as a relatively small amount in the total of the build, then it cant be of too much benefit or a hinderance

this came up in one of the discussions i had with Will at jhh terry, and what they do on some cars is run a header tank with extra points plumbed in around the head (like an arc kit for the gtr but with more points drilled into the head)

Well for me to make up some fittings to replace a welsh plug near the rear of the block is pretty easy... You could run a t piece somewhere to the fitting to help with the cooling... But i would need to know the size of the welsh plug.....

I have contacted a couple of people regarding this and still waiting for a reply, but i think that this might be a cheap aid...

Not sure what other people think but just thought that i would put my 2 cents in...

Paul, you say add more fuel, how much more? currently on my PowerFC settings, Cylinders 4,5 have 0.5% more, and Cylinder 6 has like 0.7% more than the rest..

What does everyone have theirs set at?

sacrifice your heater hose at the back of the block and plumb it back to the radiator. creates enough flow. but really, my gts4 was running enough hp to show a mack truck and it never crossed our minds. short of pulling the thermostat that is.

i run a similar set up to this and i found it was the only thing that could control water temp after continuous drifting.

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
