Ran a temperature cycle across it and see if we can log some data....

who knows their threads.....??
This apparently has a 1/8 GAS

I'm thinking I best swap it for an M12 1.25 or M8 0.75....
Which would be the easiest to find fittings for.

I want to place one into each of the send/receive Charge Air Cooler lines (to start with) so will have to make up some copper tube with solder bungs to suit the thread.

just picked up a digital flow meter to boot....

When i get back i will use my water heater, vacuum cleaner per your idea to measure flow, heat rejection and static friction loss . Should be informative.. Woody

Plan is to have this inline to my SC readout in the car with the in an out temps....hopefully an input to the Dashdaq (eventually)

 

Temperature Sensors

Not having a CACooler hose around handy - I'm guessing a 19mm "T" will cut it - but not sure.
Can someone tell me the OD of the aluminium pipe feeding the Charge Air Cooler - see attached
I seem to recall it looked like 12mm or half inch?

Found these garden PE fittings - figured they'd be cheap (for now) - just gotta get a
15mm BSPF to "whatever"
to screw the sensor into...the "whatever" may be determined by whatever thread adaptor I can get my hands on.

Pipe run

Sketched up a pipe run - doesnt have the Supercooler shown (yet) - some say its overkill....and a three way valve arrangement is the go. I'm guessing - if you dont want the Killerchiller - you simply just turn the AC off via the dashboard switch.....

AC On or Off?
Here where I live in Australia (on the coast) our temperature range is 5C-40C or 40-105F - so AC is only needed on steamy days - rare. The problem might be - you dont want to run the cabin AC - but you want to run the AC for the SC

Comments appreciated

 

That looks like a really great sensor for the money, great buy!

 

In/Out Temperature Senders
Well I think I've sorted the Temp sensors. I'm still in expt. mode, but the 19mm T looks like it will "do da bidness"...I bought a plug and end cap and will drill the 4mm thick cap and self tap the RTD into the cap.

I'm hoping it will be up to the prs. I think I read somewhere the stock bosch pump puts out a max 10psi dead head - so this 1/8 Gas thread may hold - we'll find out. It's possibly an advantage - its a fine thread self taping into a 4mm PolyEthylene (PE) material and I think that thread combo lends itself to self taping.
Hey - those little threaded barbed garden risers handle mains pressure into thin walled PE tube - anyway - here's hoping....

Flow
Well the flow meter's going to be a few weeks, so I'm going to assume 2.7gpm (10Lpm) for calcs

Brains
I'm going to need a PICAxe setup to measure the hall effect flow meter - yes, cheap meter SRT - but maybe $$ on the brains. I'm hoping to tie the temps and the flow back to the PIC and with an LCD in the cockpit read out temps, flow and it can calc kW "absorbed" (BTU's) by the water system.
I'm already thinking of doing an similar imbient sensor down on my IC (front of car) to compensate. Humidity - hmmm...minor

Recording and other data alignment
Still gotta work out how to (what to) ultimately transmit back as a signal to the DashDaq for logging(if I ever get one). I'm doing the LCD thing so I can get a feel for temps/kW day to day and allow my "optical integrator" to make some assements. My foot will know throttle position...so will wait and see.

The plan is to get some data on -kW heat rejection ....then start changing things...pump/front IC/Killer chiller (on order), isol kit, CAC clean+baked potato etc. and accumulate numbers for each step in the journey.

 

Well self taping seems to be the go.
assembled and pressure tested to 5-6bar (85psi) and 70F tap water - way above the pumps 10psi.
I'm thinking temperature may yield different results - PolyEthylene may not like 80C (176F) and loose its resilience.
Thinking a lock not on the inside might be insurance of it poping out....but then you think of the nut coming loose and getting stuck in the CAC. So then you think - maybe a sealant on the inside where the nut is to stop it coming loose....of course then you ask....what kind of sealant.

anyway - moving ahead....

The sensor riser is possibly a little far away from the main flow stream (for my liking) - but I'm using a self justification that there will be significant turbulence in the region and that should transfer temperature quickly....fX

Got some cheap coolant hose and clamps so I dont have to hack into the OEM stuff....install in the next couple of days and then some readings (2 multimeters to start).

Well time has moved on, and Xmas came and went here in the land of Oz.
Under the tree a Fully programmable ArduinoMega Microcontroller pack and all the necessary bits to.....
54 Digital Inuput/Ouputs (I/O)
16 Analogue I/O
16Mz processor
+
USB Port
GSM (maybe later*)
ELM327 and CAN Bus Chip
16x2 LCD Screen
=
OBDII interrogation and recording to csv file along with all those lovely I/O
Scrolling display of various sensors
calculations and reports
relay actuator signals (initially for IC valve with KC)

And I hope to tailor it into a unit that fits neatly and un-noticeably here with LCD and USB port on the front face.....(attach) Leaves room for some expansion

* The neat thing about the GSM is that it samples 5 times per sec and can log your ECU output with GSM data - so you can scruitinise your hill climb v engine data.
