mellonman Posted August 26, 2011 Share Posted August 26, 2011 (edited) Guy and gals i was wondering how can you monitor the intake temps on a jspec im going to be fitting a thermal intake gasket and was going to record the differances to see what gains are to be had but how can i do this ?

Scott Posted August 26, 2011 Share Posted August 26, 2011 Where do you want to measure the intake temperature? If it's before the gasket then it'll make no difference. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted August 26, 2011 Share Posted August 26, 2011 As above, the gasket seperates the intake manifold from the head so measuring temps wont mean anything. Quote Link to comment Share on other sites More sharing options...

David P Posted August 26, 2011 Share Posted August 26, 2011 Because of the weight of the charge-cooler I have decided against using a thermal gasket, the AIT sensor is located after cc and before runners. Quote Link to comment Share on other sites More sharing options...

To be honest the difference noticed on the gauge was probably from the lesser heatsoak on the sensor housing rather than the actual air temp.

It does make sence to me being that if you touch your intercooler its no way near at hot as the intake so it must be getting that extra heat from the engine + bay. i have changed the title to hopfully get someone that might know have a look, i did bye it from ryan and even he said it drops the temps alot in the for sale thread Edited August 26, 2011 by mellonman (see edit history) Quote Link to comment Share on other sites More sharing options...

No matter what sort of insulation you put between the intake and the head the intake is still going to be miles hotter than the intercooler. The question you need to be looking at is whether putting an insulator between the intake and the block drops the intake enough to actually have a positive effect on the air. We know that it has a positive effect on the intake air temperature sensor, but does it actually have any effect on the air. Remember that the intake sensor is going to be mounted on the intake and therefor the casing of the intake sensor is going to be effected dramatically by the temperature of the intake. I reckon that the difference in the actual intake air temperature will be negligeable. Easy way to check would be to fit a long thermocouple probe, that way you could centralise the probe in one of the intake runners and the housing of the sensor would make no difference.

mellonman Posted August 26, 2011 Author Share Posted August 26, 2011 negligeable difference just like heat wrapping our exhuast but we all still do it, its was a cheap mod i wanted to know how to test the intake temp to have some real results before and after fitting so could know the facts. to save debaits about it Quote Link to comment Share on other sites More sharing options...

As I said, the housing of the sensor will be affected therefor skewing the actual air temperature. Anyway, I feel like I'm going round in circles and my points aren't being grasped so I'll leave you to it Quote Link to comment Share on other sites More sharing options...
b_have Posted August 26, 2011 Share Posted August 26, 2011 I logged mine via the powerFc datalogit, my ait's were very low due to a combination of a cold air box housing the filter built under the headlight and meth injection. The thermal gasket will help prevent heatsoak in traffic/staging but will be minimal compared to the other mods. Quote Link to comment Share on other sites More sharing options...

mellonman Posted August 27, 2011 Author Share Posted August 27, 2011 i agree too, thats why i want to see what the differance was with and with out, i have a fic which i could maybe log the ait if i knew the correct voltages of what comes out the stock sensor to corrrect temp Quote Link to comment Share on other sites More sharing options...

If your AIT sensor is in the stock position, the readings will be tainted by heatsoak, I moved mine to the ic pipework (just before the throttle body) for that reason.

I've mentioned the sensor being affected more than the air but it seems to be falling on deaf ears. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 27, 2011 Share Posted August 27, 2011 Guy and gals i was wondering how can you monitor the intake temps on a jspec im going to be fitting a thermal intake gasket and was going to record the differances to see what gains are to be had but how can i do this ? A logged probe before the gasket and after the gasket, but it will be a waste of money, the sir flow is so fast and of such volume that the temperature of the walls of the "pipes" under boost or at cruise will be of little significance to the AIT as a whole. Heat soak may be effected, but over the course of a few seconds it will be negligible. Google thermodynamics in tubes. Quote Link to comment Share on other sites More sharing options...
mellonman Posted August 28, 2011 Author Share Posted August 28, 2011 sod the test then, i will just fit it and know that its there and doing not alot but abit lol, cheers for the input guys Quote Link to comment Share on other sites More sharing options...
