Mine was fitted by Courtenay and it runs constantly with the ignition on. So I have the pleasure of listening to the chargecooler pump if I want to listen to the radio, without the engine running (not to mention the fcuking stupid beeping auxilliary gauges).

[NickB787]

same here as Techieboy for wiring of the cc pump Chills pump seems to put out more flow than mine maybe time to change my pump as it is about 7 years old now.

At least 1 check can be done relatively easy..

 

How hot does the coolant in the CC tank get after a brisk run? Perhaps check with an IR gun or a simple thermometer dunked in the tank.

 

Or if the tank is mounted on the outflow from the laminova's and before the pre-rad: does it get significantly over ambient temperature? Aka, is there sufficient heat transfer happening from the air to the coolant in the laminova's?

 

Should at least give an idea if something is 'up' if the results do not match the expected behaviour.

I'll try give this a go this weekend. I can say in the past I've dunked my finger in and it's never been anything but mildly warm even at track days.

 

Is it a new TMAP?

confirmed, yes

 

 

Could it be that the coolers need a clean out as per the service guide for the yankee cars?

Good shout, I'll see how I go with the above.

 

When Lee and Vocky put the Saab head I'm pretty sure they said they were clean.

But at the same time the PCV valve was opened, potentially oil has been pushed up into the laminovers?

 

I've not really driven the car a massive amount since it was opened, but hmmm

bit late to this one...

 

as said earlier, temp will rise as the by-pass valve opens, so if you have been giving it some stick, then back off to light throttle cruise, the temps will go up, if you then give it a boot full, it will drop again.

 

How much all depends on where the sensor exactly is, nearer the engine, the more this will become apparent as with low airflow and back-flow from the inlet ports, temps at the port face get pretty hot.

 

Other bit is how much heat soak the sensor itself picks up from it's mounting. 

 

 

[siztenboots]

the rise time on the sensor is probably quite long, you really need a k-thermocouple in there for fast response

[siztenboots]

quick look at the specs for 2.5bar tmap , t₆₃ = 10 s , resistance at 20°C = 2.5kOhm

Cant you connet in with a T piece if you have a boost gauge fitted and get a temprature ,reading from their? Or tap a thread into the charger put a sender or thermo coupling on their ? I believe CS did one on Nicks to check the inlet temps when it was being mapped.

I do similar with the Honda's:

 

 

fast open element IAT into the manifold...

 

this does exactly the same thing though, as soon as the bypass opens, the temps jump up, not a problem as in this condition, the engines never going to det or the like, the only problem is how you use the temp as a fuel/ignition modifier

 

on the Honda's, it;s easy, you have different modifiers for different engine loads, so you can separate out the fuel/spark corrections for high load without making the same (bad) changes to the light throttle stuff

Saw this on a supercharged MX5 - uses an intercooler

As if I'd have something as advanced/chavvy as BOOOST gauge

[Sutol]

Sorry try this. Just wondered if something like this could work in a vx?? This uses an Intercooler.

That's a map sensor...

[Sutol]

No, I was thinking of something to to get away from using laminova cores. That discharge from the charger does look a little restrictive though.

[Scuffers]

probably not that bad, air volume will be a problem though...

[Sutol]

The pressure drop after whizzing off the charger, slamming into a brick wall and then hanging right will be big. Just put it forward really for a bit of out of the box thinking prompting.

[fezzasus]

Chris, best solution would be a diblias inlet sent to a turbo charge cooler.

[Scuffers]

Nothing like that bad, air does not come out of the charger at 90 degrees...

Shoving a fist full of bees up your ass would be better than the dilbert solution.

Not sure how an inter cooler post SC is necessarily better than a charge cooler.. Given the mid engine layout in the VX with restricted airflow to an inter cooler?

I'm not sure either Steve but I'm not impressed with the laminovas and not being able to run the pcv system as it was intended for fear of clogging them up. Also there would be a weight saving.
