The pipework you use from the thermostats etc has to have the right internal dia as well.

Cant you just reduce the dia of the dump holes to give you more pressure?

Use 2 SS nuts and boltsto block the holes and re- drill 2 corect sized holes
What you have to be carefull of if you reduce the flow too much and alter the position through the plate, is that you don't melt the water pump.
While it's apart it's a small job to 'dry stack' it. Block off all the holes fit 2 pipes about 8 mm down to just above the pump and crinp the ends so they form a spray. A 1mm hole in each pipe spraying the outside of the tuner and it's done

Changed the CLE for the standard box this afternoon, ran engine on the muffs, gauge shows WATER PRESSURE (just over 1psi at tick-over) warm tell-tale.
Changed back to the CLE, piped up the 2 low water pick-up points, ran at tick-over, gauge hardly moves, hot strong tell-tale.
Is this normal with a CLE?

The 1 PSI pressure is probably coming from the hosepipe, the muffs providing a reasonable seal. Whereas if you are just putting 2 loose pipes into the cle holes you won't be providing a good seal to realise the pressure from the hose.

Sorry to bring such a old post up, but I'm on with the same thing on my XR2 and two plate tuner, its dumping too much water so need to seal the triangle water dump up, just wondering if you need to re-drill a smaller hole in to avoid melting the water pump?
Cheers,
James

Good luck with your quest James, I gave up with the CLE after melting too many water pumps.

Thanks Wayne, If you don't mind me asking what was the reason for the pumps getting too hot? Did you have a one piece tuner on?

I once replaced an impeller and forgot there was still a rubber on the tube (going into the mid). I placed a new rubber on the impellerhousing so there were 2. The PSI was very low and the engine was running hot!!
