Water to air intercooler......... Closed loop

[rusty rider]

Just need to get that cold air intake going now and you should be set!

Mine seems to be working quite well.
With the water pump unplugged, my charged air temps were getting up to 155.
In same type of riding after I plugged in my water pump, it would only get as high as 75 deg f.

whats the actual performance gain? can you notice anything between the two temps in how the machine runs out?

So I built tossed together another exchanger (sorry it is not on a cat but it is in the cat section). I left it gap between tha exchanger and the tunnel, hopefully it don't bung up with snow.

On my m1000 I went small on the exchanger (4X16) and it seemed hard to tune, I dumped some coolant out of it so the water to air cool was only abour 60% full, it run way more consistant and still helped cool the intake charge.


Rusty how is your settup working?

Finally got my WTA sled finished and after seeing how Boyko had issues with only running a dedicated system with the small front cooler (similar to mine) I decided to run mine using engine coolant. I eliminated stock DeGas bottle and routed the coolant from engine through stock front cooler, to rear U-cooler via running board edges (CR tunnel) and back through to extra front cooler (below stock front exchanger) then to the intercooler and back to the engine. Pull after pull on hill and I/C is lukewarm only. This is with little to no venting on my hood (only have dash vents and still have headlights). Sled runs awesome and consistent. Just changed from Attitude box to Dakota Performance PCV and hope to dial it in even better.

How has everybody's closed loop systems been working?

Mine worked awesome from the day I put it on. It is amazing what it does for reed life. Mine had over 1000 miles on them when I pulled my motor and they look like brand new. I think the biggest thing with the closed loop is getting the size of the exchanger right.

I agree, need a lot of volume so that charge temps cannot overcome coolant temp. My system is holding a bit over 3 quarts. I have driven machine around with pump unplugged and it runs not nearly as well with it in operation.

Well I am diving into the water to air intercooler system.. I have done some research and found a intercooler that draws heat 2.2 times better than the frozen boost type intercoolers. I am going to try and make a waterpump that will fit between the oil injection pump and the block. I have found a few options on impellers, I just need figure out what rpm the oil pump shaft rpm is.. Anyone?

 

[rusty rider]

What inner cooler did you find? Need one for my m8 build too. I liked the frozen boost one on my tm1, worked very well, good throttle response down low still and kept it very cool. Shoot me a call Jim.

I just bought a cpc m1000 with a boost-it kit. Do these sleds have enough juice to run a big water pump for the water to air I/C? The one on my Apex works great and I'd like to put one on the m1000.
