Overheating after GTM stage 1 supercharger installed. .plz help
 

Hi all..
I installed GTM stage 1 supercharger kit on my Z370 2012 AT transmission. I drove it on street it is much faster then before...however I noticed that temp is raising to 4 & 5 on the engine heat electric gage. ..this is at night and driving normal...if speeding it reaches even more than half gage! !!
This was not the case before installing the supercharger !! Can't know what is wrong...I noticed that there was detonation so the mechanic reduced the horsepower by 15HP and it was gone....please help me

what tune are you using? the flash that came with the kit?

Did you not install any coolers?

Yes oil cooler is there and intercooler

I took it to a workshop an they tuned the manufacturer ECU on the dyno

What software did they use, Uprev? Unless im not remembering the water temp gauge correctly, 4 to 5 dots sounds normal, unless the scale is somehow different in the UAE, can we have a picture of the gauge ?

Am not sure which software they used...and the gage is exactly the same as US cars...normal days it's 3 bars only...in mid day around 2 pm when outside temp is 42 C° it reaches 4 bars....however now it at night and outside temp is only 31C° and it's going 4 to 5 bars on normal driving and if I speed it goes to the 6th and more bars

The gage looks like this
z370 heat gage -

It has reached the 10th point when I drove at a speed of 210KM for less than 5 minutes constantly

It may be worth taking it back to the shop that installed it, they would know better than anything how they built it and what they encountered and didn't tell you along the way.

Besides they should stand behind there work and clear any of the issues

4,5 dots is normal for me after a bit of driving. If you're driving around at 130 for 5 minutes in 31 degrees C ( 90 degrees F) in the UAE, I'd def recommend a bigger radiator.

The dash gauge is not linear, IIRC. Buy or borrow an ODB/CAN scanner and see what the water temperature really is.

I took it and they tried everything and Check all...nothing seems to be fulty

My friend own same car but he installed Stillen superchar. ..and he really drives fast pushing the engine to maximum limits...6 bars was the highest he recall seeing. ..stock radiator

Potential overheating issues aside, did you do anything to strengthen that AT of yours?
