R33S2 Posted December 5, 2008 Share Posted December 5, 2008 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?

lachlanw Posted December 5, 2008 Share Posted December 5, 2008 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 Link to comment https://www.sau.com.au/forums/topic/247824-extra-water-cooling-for-6th-cylinder/#findComment-4302623 Share on other sites More sharing options...
paulr33 Posted December 5, 2008 Share Posted December 5, 2008 add more fuel to cyl #6 via the ecu tune Link to comment https://www.sau.com.au/forums/topic/247824-extra-water-cooling-for-6th-cylinder/#findComment-4302714 Share on other sites More sharing options...
R33S2 Posted December 6, 2008 Author Share Posted December 6, 2008 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.

R31Nismoid Posted December 6, 2008 Share Posted December 6, 2008 ^^ 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 Link to comment https://www.sau.com.au/forums/topic/247824-extra-water-cooling-for-6th-cylinder/#findComment-4303435 Share on other sites More sharing options...

shanef Posted December 7, 2008 Share Posted December 7, 2008 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) Link to comment https://www.sau.com.au/forums/topic/247824-extra-water-cooling-for-6th-cylinder/#findComment-4304533 Share on other sites More sharing options...
tufrx3 Posted December 12, 2008 Share Posted December 12, 2008 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...

Dose Pipe Sutututu Posted December 22, 2008 Share Posted December 22, 2008 add more fuel to cyl #6 via the ecu tune 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?

nizmonut Posted December 22, 2008 Share Posted December 22, 2008 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.

DRIFTER Posted December 24, 2008 Share Posted December 24, 2008 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) i run a similar set up to this and i found it was the only thing that could control water temp after continuous drifting.
