Tony,
Nice shop! Looks like they can do just about anything you could think of asking for.
So, how's your car been doing? Still running like a "cool top"?

Have you sorted out how you're going to run a 'stat?
Cheers,
Bill

Its running heaps cooler also noticed on really hot days the aircon works better. The reason that is that in the old days and with the wifes car once the engine goes over a certain temp the ECU suts down the AC to try cool the engine. I haven't sorted the Thermo plan yet.

Did you see the way they went to so much trouble to get the coolent outlet to feed properly by using a tapared suction pipe. It sure makes what Adam was doing sound smart.

Tony,
I noticed that! Probably cost prohibitive on mass production runs

Post up when you get your 'stat situation sorted out.

I was thinking that it would not be difficult to build the larger outlet for an alloy radiator by utilizing a simple hammerform. In fact it could be easily repeated accurately without investing anything for tooling. I have access to a very large woodworking shop w/free materials so I use this method a lot, even for one-offs.

BTW, Docking Engineering was my inspiration for this intercooler I built. I started with a WRX core and fabricated end tanks from sheet alloy using simple hammerforms. A tapered radiator outlet would be far easier to make than this was, FWIW.

Show off!!

Now, go off and make a couple of outlets for those of us with PWR radiators!

Impressive! Nice work Bob!

Ah see, you're old-school fab like me! Anneal that metal and form it around die sets. Brilliant! :lol

Well you learn somthing every day, I never would have figured that you could do that. I am convinced if we run our engines to 9,000 that's 300l per minute we are going to have to make sure we get it out of the radiator the best way possiable.

I would just need a radiator to pattern from that has been marked with the new outlet location. Once I had that, I could make an outlet which could be shipped out and welded on locally.

Okay, so who has a PWR and lives close to Bob?

Tony -- think we could get enough benefit from just replacing the stock outlet with one of Bob's custom pieces versus using a custom piece relocated to the center of the bottom tank? I'd like to minimize the amount of cutting and welding, if possible.
Thanks.

-Bill
p.s. Bob -- how long would you need the radiator? Worst case, I'll ship you my PWR.

Dessertrunner · #**1046** 02-09-2010, 12:33 PM

Bob I can mostly do 1 better I have the plans of the last PWR I had made so I could send that to you also I could design the position and shape of the new out let.
Would that work.

The more I think about this the more it makes sense if you do it for air you would think it would be done for coolant. Friction on water is greater then friction on air.

Tony,

Here's another thing to possibly factor in. If the outlet is going to be moved toward the center of the bottom tank, is there an existing 42mm ID radiator hose (from another car) that would be a "use as is"? I've got upgraded silicone radiator hoses now (stock SVX configuration/size), so I'd like to be able use the same type of hose on the modified outlet. Adam/Bob - what does the lower hose on a WRX look like? Might it be a candidate?

Lower hoses are nearly identical between the two cars. It's the upper hose that's different due to the radiator inlet location being different on the two cars.

just started reading this thread.. and decided i would loose my mind it i read all 70 pages haha. What did you guys end up doing to cure the overheating? I have been trying to figure out what to do so mine wont over heat with the power im looking for.

I was going to run a large electric water pump but in the first few pages you mention its something internal as well as the cross pipe. If you could tell me which page you explain what you did to cure it that would be awesome! Or just shoot me a PM

SVXRide · #**1050** 02-10-2010, 08:46 AM

short answer is enlarge the inlet to the water pump and outlet from the radiator to 42mm ID. Slightly longer answer is also to relocate the thermostat to the line feeding the radiator and enlarging the crossover pipe at the top rear of the engine. Oh, yeah, you'll need to go with a PWR radiator or something similar, the stock radiator just won't cut it.
