That pump flows 23L/min, should be plenty

You're not too far off finishing it, looks like most of the hard yards are done.

so probably turning over the water in the core 50 times /min... plenty

Few more bits showed up today! Thermo tec Insulation tape (I expected it to be more but quality seems good and hopefully it makes a difference!) also the warrenty replacement oil pressure sensor for my SPEEDHUT gauge (first 2 got "lost" in transit) this time it was sent express with a tracking number... order made Tuesday and it was on my tool box by lunchtime today America -> Australia. (Aus post is a fucking joke)

Also as I am an inquisitive creature I did a few tests on the small body water pump that came in the cooler kit and I must say, I pleasantly surprised at just how well it actually did!! Will probably upgrade to a larger Davis Craig or bosh unit at some point but for now I will be giving this one a red hot go.

Basic set up to see how long it would take to pump 20L from one drum to the other with minimal restriction to flow and the battery voltage of a running car for power supply then measure current draw.

Pump is rated at 23L a min.



Turned out to draw about 1.2A /1.8A depending on load (pumping from one drum to the other at ground level / pumping from ground level up about a meter onto the workbench)



Both test done around 13v /13.4V (Mazda 3 MPS sitting idling as power supply for my test).



Pumping on ground level with minimum restriction took roughly 47 seconds to pump 20L! Not bad I thought!

So then replicate the test but this time with the second drum on the bench about a meter above the supply tank outlet, this took about 70 seconds to pump 20L still doing fairly well!



As you can see it's fairly pumping! No fire hose but didn't seem lacking that's for sure was confidence inspiring for the first incarnation anyway. (Bigger pumps are easily and readily available if I want to upgrade) .



Best step would be to see exactly how much it flows a min in the car (purely for interests sake and data / comparison later on if I do upgrade pumps).

There is no such thing as too fast a water speed but I think the returns from it drop like a stone pretty quickly not withstanding pumping losses and issues with high speed fluids.
A lot of effort went into finding those pumps, they are the only ones out there that are affordable, quiet and not shit lol

The heat exchanger efficiency is going to be the biggest contributing factor beyond the ambient temperature.

Quiet and not shit love it hahaha

Looking forward to getting a GOOD chuck of tomorrow to play with the car! Things try to do tomorrow.

#1. intercooler and it mounts finished.
#2. Pipework from cooler to throttle body finished.
#3. Die grind inside throttle body to ease transition of pipe size (pictures to follow).
#4. Start on heat exchanger (removing baffles from condenser tanks and making inlets / outlets for coolant)
#5. Mount heat exchanger and condenser to radiator properly.
#6. Mount intercooler pump and plumb to cooler / exchanger.

And so much more but I'll be happy if I can get a good chunk of that finished!

[_glenn_archer_]

Everything takes so god damn long to make haha

Had to re-make the baffle that I removed... I decided to keep with the twin pass to try and keep up water speed in the core and less holes in the body is also good ;p



The plates are only temporary to try and stop excess heat from damaging the core while I was welding, just did multiple passes with low amperage to build it back up.



Everything is sooooo tight, trying to make everything fit and work together is proving difficult and time consuming!! Showing how close the coolant feed and return lines are to the turbo inlet.



I couldn't get some 19mm alloy pipe on short notice so I got the next available size up and then I had to turn down some fittings to weld into the larger pipe for the 19mm heater hose.



Had to remove the baffles from the condenser to turn it into a single pass "radiator" turned out to also be a pain in the ass lol and left some large holes to fully



Custom periscope needs a lick of paint but should do the trick?



Tiny wonder pump mounted.

Nice work!

[_glenn_archer_]

Thanks!

I'm a little worried the engine rocking will try to brake the inlet side of the cooler off... but I have done what I can for now to try and stop that. Maybe one of the straight silicone pipes with a bulge in it would be better for the application but budget is shot and I'm running out of time as usual.

Finished the intercooler today and tested it for water leaks (didn't have a spare pressure reg and or a dunk tank so fingers crossed it won't leak under pressure but it didn't leak just holding water).
The photo dosent really do the lack of space any justice, it's tight!



Might even be able to run it up in the next few days I'm really keen to see how it goes!

On a side note, anyone else set them selfs huge lists of shit to do in unrealistic timeframes and then get annoyed when you don't finish it all?

I swear I am the king!!

Does 7 years of "i will have a turbo adub at toyota nationals" count?

Modified the throttle body to take the proflow clamp this arvo and finished off the intake pipe tonight.

Was surprised the clamp actually had a LOT more movement than expected! Like so much i might try and get an extra o ring on either side just to try and limit it a little.



Air temp sensor mounted to the under side of the boost pipe as seen here through the BOV v band mount.



Make a start on the mounts for the heat exchanger and condenser tomorrow.

that fuel line is looking a little worse for wear

that fuel line is looking a little worse for wear

Agreed, been replaced under warranty once but came with a new catalog that said only "fuel Vapor safe" when I replaced it all the individual we was fine, it was only the very outer layer that looked shithouse... apparently the RACEWORKS E85 safe hose pushlock is the goods. Also have a part number for some spiral wound German hydraulic hose that is also the goods!

It's on the list of shit to do but not as high as the outside makes it look.

DONT BUY AEROFLOW PUSHLOCK HOSE! for anything to do with fuel or coolant... in fact it's just shithouse! Don't use the shit at all! I regret using it on my car deeply, I wanted a more factory "look" than braid shouldn't have ever touched it tho.

[TRD-MX62]

I'm going to try some of this on the soarer... http://www.gatesaustralia.com.au/pro...ction-hose-mpi

[_glenn_archer_]

First stuff I got from aeroflow was gates hose (don't think it was the green series stuff tho) but the second lot was this shit.

[_glenn_archer_]

After installing the proflow clamp and finding it had a lot more movement than I had initially expected I tryed to put some extra O rings on the outside of the original ones but still within the clamp body, it worked! Removed a lot of the play and actually feels like it's going to seal better also! The sleeve slips over the O ring section and then the clamp covers the whole lot and holds it form pulling apart.



Made up a turbo intake pipe that puts the filter under the intercooler.



VERY BUSY once everything is in place, this sucks balls to get the filter out now. Not like the Car is doing a massive amount of KMs but making serviceable components hard to get to is a dick move...



Pulled everything back out so I could try and insulate the intercooler and pipes with the fibreglass reflective tape, I also got some exhaust heat shield so I can try to build something around the lower part of the turbo manifold.

I think my biggest enemy is going to be engine bay heat now

Also removed my radiator / hydro fan setup so I can make some mounts for the condenser and heat exchanger to the radiator, while it's all out and the front of the engine is super accessible I should mount my compressor and change the belt path. (Few other things apparently need to change to make the compressor fit again so it might not make it this time around)
