Ok,
I know there is a diagram out there showing the flow of coolant thru the block/head. I remember the thing was seethrough and you could see blue arrows showing the cold coolant and red arrows showing the hot coolant and they pointed in the direction it flowed. I'd really appreciate it if someone could post it for me, I searched here and sf and haven't found it yet.
Thanks,
eric

For stuff ;)
I want to know where abouts the coolant passages are near the back of the head, and where the hot ones are so I don't butcher my junk head for no reason. I'm thinking of playing around with my idea of bettering AbFlug at their bypass mod although i don't really need to since i don't have a supra anymore ahahaa. I just want something to do, I'm terribly jealous of you guys with your fancy cars and fancy driving :icon_razz

They are a company like Greddy or HKS. It would deliver freshly cooled coolant directly to the rear of the head giving the No. 6 cylinder cooleing it could benefit from as it has been said that cylinder runs very hot so this would even things out, make it run better most likely. Possibly prevent it from overheating back there. Icase you think I'm nuts I didn't just make this up while eating my muffin this morning, I just wanted to improve on the already existing kit by AbFlug, a well known Japanese tuning and aero company.

Hehehee. Thanks for trying Jeff, I saw those already. You know what diagram I'm talking about tho don't you? I'm sure we've all seen it. I just can't find it!

OH that's cool.

how do you accomplish re-routing coolant paths? it sounds complicated. lol

Not complicated, only complicated to figure out where things should go :icon_razz You'll end up just needing some an fittings, some hose, and a tap.

awsome. sounds like a nice idea.

i wonder if it would be possible to super cool the intake plenum with an AC line.


i was thinking the other nigt, what if you could make a cooling system with the AC compressor and run the piping along the intake plenum, it wouldnt be touching the block so the block wouldnt stay too cold but it would keep the intake air colder until right when it enters the cylinder.

without cooling the plenum (more than the engine coolant will) you get several feet of warm to hot metal the air has to go through...not the best IMO. but i dont know how much cold air can benefit horsepower...

maybe its not worth it.... you'd have to cool the plenum a long time before racing and shut off the ac before your run... or the ac might offset the cold air power gain.

just random idea...

If you're re-routing the coolant by tapping into the head where the water jackets are, wouldn't you run the risk of getting less coolant into certain areas of the head due to the coolant flowing through the new lines?

I don't about this for sure, but it seemed like a good thing to point out...

It would be nice to have a smaller separate radiator mounted somewhere in the bumper and run cooant lines up the intake manifold. This would be plummed into a type of "cover" that would be highly heat resistant on the outside, but would have a good heat exchange rate on the side laying on and around the intake manifold. This would also be powered by a small electric water pump. What do you think about that idea Figit?

sounds good, i'm sure someone could make up a blanket of flexible hoses with some sort of reflective sheet on the upper side like you said. or maybe before the plenum and intake manifold are installed, copper lines could be bent and contorted to hug the intake and attached solid, and then covered with heat shields and mounted to the engine. then you could run whatever cooling system to this via connectors - then you can remove the intake when you need to.

i thought of the extra radiator but you'd have to find a flud that would actually get cold enough to help, or maybe you could rig up an ice system with water what woulc circulate over ice cubes placed in the tank early before the run. ice absorbs all the heat from incoming water, and sents cool water to the intake....it would only be temporary though.

but i dunno...maybe since the system is just the intake and doesnt touch the engine block water jacket it wouldnt get really hot? i was thinking of something cold cold.... like a No2 sprayer on the intercooler or the AC piping. i'm not sure what pipes are that cold but i know that on my mom's van, there is an exposed ac line i touched once and it was very cold...so if that....freon maybe...could be re-routed (remove cabin AC in the process) you could hit the AC 10-20 min before racing and trigger it off when the tree begins to light...

but then there's the problem of such differing temps.

i'm a bit worried that such colt flud running against metal that is very hot on one end might cause some bad effects. i'm not to familliar with this kind of thing but hopefully it wouldnt cause warpage...

It could actually crack if the metal it comes in contact with is hot enough when the co2 or freon, or whatever is sprayed onto it. every taken a skillet outa the oven and poured ice cold water on it? Instant crackage ;).

BTW: Anyone have any input on the first part of my last post? I figured it was something that needed to be addressed when considering this mod.

yes, it could. BUT the coolant lines would probably take a while to heat up. if you had instant application of cold i could understand this but it couldnt be gradual as the heat would keep the AC from compressor from cooling the freon because its absorbing heat and also...the AC doesnt cool down really fast.

valid point though, it's a danger.

i'd be more worried about how the metal reacts to having a very hot contact at one end and a cold one on the other.

Ahahaa yeah these 2 are similarly related, but only because nobody managed to find me the coolant diagram and changed the thread direction a bit :icon_razz
