Do not want at all. At least he ditched a bunch of the random routings he had before.... apparently we were right in the end... because he did accept advice on his Holy Grail.

I guess I had to register over there to check it out, so I did. Now I hate you and myself, thanks.

This is becoming rag on Hyper day... he is now attempting to source a 90mm tb to accomodate his 4" i/c piping.

Ok, I finally got my CR membership and viewed the thread. Is it just me, or does this reroute either deadhead the flow entirely or reroute the water completely AROUND the head? Either way, blown engine results. What think?

He basically has the stock thermostat housing in place, but it doesnt connect into the head anymore. At least thats what it looks like to me.
and then hes got that giant *** aluminum thing over the exhaust manifold, god knows what that does, but I can guarantee its an epic waste of time, money, weight, etc.

He tied both ends of the head together.

Not sure why...and everything else is kinda strange, including random line from back of lower driver's side of block to mixing manifold.

Looks like a laminar-flow oil cooler, positioned so as to receive the hottest coolant in the entire system.

I just get the biggest kick out of the coolant lines fro mthe oil cooler to the radiator that have no flow because of a little thing called no pressure difference

Oh wow...and I do mean wow.

Missed that on the installed pics.

Are we sure about that?

Consider the design schematically:



Q: Which one of the two paths through the engine has zero flow?

A: Neither. They both have flow equal to 1/2 of the total flow.

Ok, this is a simplified illustration. Both of those paths have some restriction in them. The question then becomes, is the restriction greater across one than the other?

The biggest restriction is probably the head gasket. The holes in it are pretty small, compared to the passages in the head. The block itself is not much of a restriction, even though it does make the path longer.

I'm pretty sure that water follows the same basic rules as electricity in a parallel resistance circuit. Namely, that the current flow across any one resistor is a fractional multiple of the total current in the circuit and that resistor's value relative to the value of the other resistor.

If you have 1 amp total coming out of the pump, and two resistors which are, respectively, 5 ohms and 10 ohms, you'll get 666ma going through the 5 ohms part, and 333ma going through the 10 ohm part.


I hate fluids...

As far as I can tell, this is how he has everything routed.... so Joe, how does flow work with the oil cooler in this situation?

I think those lines actually have oil in them going to an oil cooler that he must have incorporated right next to the radiator, sort of like FM's twin cooler or whatever they called it. In one of the pics you can see how the top header tank of the radiator is divided right where those lines go.

I am still unsure how that oil/water cooler sitting on top of the valve cover comes into play, if that's in fact what it even is as I didn't see any oil lines going to it.

Oh, he went all out and is using those one time use heat-shrink hose clamp thingies.

Well, if indeed there is oil in there.....
But in the pics, I don't see any provision for oil lines coming from the oil cooler...i.e. a sandwich plate.

What's up with the oil lines (?) and the t-fitting and junk up in the driver's corner area?

He's using a laminova oil cooler, as Joe has already mentioned. This in and of itself isn't a bad idea. I've noodled with the idea of using one. On a standard re-route, replacing the straight hose from the rear of the head to the radiator with an inline laminova oil cooler would provide very effective oil cooling without requiring any frontal airflow real estate. Downside is that oil warmup would be slightly longer since the oil will be losing heat into that cooler until the thermostat opens and 190 coolant starts flowing through it.


But ... someone explain to me how there is any significant coolant flow through that oil cooler ? One end connects to the back of the head. The other end connects to the front of the head.

One end connects to the back of the head and one end connects to the front of the head. ??

If the thermostat is in the front of the head ... I don't see how it's effective.

If the thermostat is in the back of the head ... why does it plumb into the front water neck? Why doesn't he just run that directly into the radiator?


Edit: Looking at the very first picture, is there a coolant passage there into the head? Or is that just a plumbing fixture in front of a blockoff plate? I can't tell. If flow into the head is blocked off there, then this actually makes sense to me. The thermostat's in the back, the oil-to-coolant heat exchanger routes to this, and from this to the radiator. Kind of convoluted, but it keeps the radiator hoses manageable and solidly mounted. No weird Z-bend in front of the motor to flex around and stuff.
