Re: Methanol/water injection
40+ above ambient when you're not giving it a hard time sounds like the pump isn't on. Can you reach the pump to listen/feel if it's on? Otherwise syringe a little liquid out so you can see the inlet to check the flow.
I don't know if your pump has a safety switch in it to turn off if it detects air, otherwise it might be something simple like the fuse.
There is also an issue with the LSA intercooler cores collapsing at the end which inhibits flow thru it. Could be possible that it's bent and causing a bottle neck if there's very little flow.

Yes common issue with the LSA internal brick either distorting or rupturing, you can have it removed & braced to overcome this problem.

Finally got around to doing this today, you are spot on mate, there is no flow whatsoever. I even pulled one of the pipes off and absolutely no suction. Now to try and trouble shoot it.
The fuse seems fine (it has an inline fuse under the engine bay). I assume the pump should be running all the time when the engine is running? This would certainly be accounting for some of that 40 above ambient IAT's that I am seeing, surely. Yesterday morning 18 degrees on way to work, by the time I got to work (22km) it was rock solid on 58 degrees IAT.
Re: Methanol/water injection
Rod might need to put a voltmeter across the leads to the pump to ensure it's getting power. If the pump is electrically operating then perhaps as mentioned above it has a shit load of air in the system, sometimes can be a real pain to purge them too.

Thanks Mick, Brad just rang me and said same. If it is getting power need to pull the hoses off the blower and force some air through in case the pump has an air lock and is cavitating. Off to try these things now.

I would have thought that Brad would have noticed if it was not pumping when he looked at it. Might have faulted since?
I have wired up my pump so it goes on as soon as either ignition or accessory position is switched on & can certainly hear it running.

Just pulled the plug off the pump and there is definitely power to the plug when the ignition is on. Cannot hear nor feel pump running with hand on it. I guess next step is replacement.

:yup: faulty pump easy fix.

Yep, just have to decide what pump considering that Davies craig was about $180 and lasted about 5,000 km. I like the varimax that Gary mentioned, can't seem to get it in oz, so might have to order from o/s.

Never really like DC stuff, bought one of their Thermatic fan thermostats once for one of my early Holden projects, no matter what I did it always leaked & was installed exactly how they instructed.
In the end I bought a Honda thermostat with an adapter & no problems.

Was talking to Brad about them, he reckons good years ago but have dropped the ball.

I reckon it is exactly the same pump Rod. :cheers:
