So I guess there are a few things I can still try before panic sets in, none of which are likely to make a massive difference on it's own, but perhaps when added together it will be enough.ricster wrote: ↑13 Aug 2019 15:02 Peter, is your turbo both water and oil cooled? Nope, just oil.
I don't have an accurate water temp gauge ( madman ) etc, so can only speak from the standard dash gauge. On mine it never goes up passed halfway. In fact it sits to the left of the wiggly lines on the gauge even on a long climb. My car water temp gauge is actually surprisingly responsive. 100 degrees is pretty close to the top. But I do not have my turbo connected to the water. I also have a monstrous radiator that I have no idea where it came out of ( was told its from a Cabstar, but have been told that it isn't ). The top mount vs front mount will have an impact on cooling for sure, but I am surprised that it is pushing the boundaries on yours. I have a brand new custom Ally radiator which is pretty much as big as the GQ body can fit. But it is pretty well known that the GQ is pretty limiting in that respect, and pretty marginal when it comes to keeping the kettle cool.
Do you have the full shroud around the fan? Jip
Another thing I think can have an impact, and I'm not sure if the GQ has this or not, but the plastic "deflector" that we all take off when we fit your bash plate, can have an impact with negative air pressures not being achieved as high to assist with sucking air in through the radiator. Should probably try something down there. Currently there is nothing, not even a bash plate... This also mean that the side rubber skirts between the engine bay and the wheel well need to be there and in good condition again to assist in keeping a negative air pressure in the engine bay. Those (or replacements thereof) are in place and in good nick.
Maybe give it a try by placing piece of rubber matting on the angle of your bash plate ( like a spoiler, for the inner boy racer in you....hahaha ) and see if there is a difference.
Alternatively, Hows your viscous hub? Relatively new and seemingly good. Also, since the issue is primarily at freeway speeds, unlikely to contribute much.
Possible extra advice... the rubber foam sealer between the body and the radiator to stop air leaking around the radiator may need attention. The radiator is pretty much right up against the body, with very small gaps. But I do want to try stuff something in there, just don't have small enough hands and thin enough arms...
