You should see spikes in temp with every application of the throttle lasting more than a second or two, but instead you see heatsoak.

I think the reason here is that the IAT sensor body is very heat conductive, sits in a heat conductive supercharger plenum, and probably gets more thermal conductivity through its body than it does from the charge air.

@King Tut

Picture of where it sits in the manifold tomorrow.

Unfortunately it is a nice and simple design but the sensor sits out side the direct air stream. There is a port that leads to it and it does give you a better idea of what is going on. It would be more effective to move the sensor into the direct air stream. I would recommend keeping the normal plate for the map sensor in place and drill and tap the manifold to put the sensor in after the blower / intercooler to get a more accurate reading. You can get a gm open element sensor kit with the connector for around 35 to 45 dollars, then just run 2 wires and and rescale the sensor settings in the ecu. You will see the sensor heat soak a bit sitting at lights or when you have shut the car off, such as running into the store and such. Heat soak will be much more pronounced when the vehicle sits not running as compared to sitting at idle. These are just my opinions from what I have seen on other platforms. For now on this is what I will be doing when I install one of these blowers though. There are other sensor options out there as well to look into that will work for this type of application.

I'm pretty sure that Mark@Abbey m/s has adapted the plate to take a sensor that sits into the air stream. That's what will be going on mine. I should be able to report back in the next month.

Would love more details on this Mark@abbey m/s!

Sorry for the delay in keeping this thread up to date;

Yes we have developed our own IAT kit that paces the Bosch fast acting sensor in the airflow;

Sensor and plate



We have to modify the manifold to allow the Bosch sensor to put direct in the airflow



we modify the loom to allow the IAT to be inputted on the normal IAT wire;

We have just done some more tuning on our Demo car , fitting a HKS manifold running no cats at all and a 69mm pulley , seeing some great numbers now;



spent sometime on the dyno yesterday and I now can remove the dip totally in the torque/power curve.

Waiting for P tuning to hopefully ship me on there manifolds(headers) very soon.

Next mod will be water/methanol injection(I know I said I don't like it before) but I have spent sometime looking into it and I have a pretty trick idea to allow the car to be tuned nicely on the water/meth mixture.

Will keep this thread up to date.

thanks

Jesus, those are some incredible gains in the low end. The top end looks good to, BTW.

Do you have the IAT logs to show how the newly fitted sensor is working. Would love to see a multi pull session with the current set up. It is intercooled now, correct?

Thx

[sw20kosh]

Now that is a proper IAT sensor... The fail FA20club sensor was for fluid. lol

Would be interesting to see logs of how it is detecting air temps during a wot pull.

I've had this sensor setup on for some time now, it works well. Plenty of log data of it on normal and fast driving. Shows how the manifold heat soaks after being stationary but also how quickly the temps drop once moving again.

[Lawnik]

@Kodename47

Please share some of these logs, preferably the hard driving ones. You got this from Abbey?

[Mark@Abbey m/s]

The FA20 IAT is a IAT sensor not a liquid sensor but I agree it doesn't get a good airflow over the sensor.

Our car is still running this sensor and the IAT temps do "hang" where as our sensor
set-up reacts quickly.

I will get some logs uploaded sometime over the next few days.

thanks

If you're replying to sw20kosh he was talking about a sensor that another vendor sold, they were called FA20club and........well they suck.

Looks good.
