Guru Posted May 29, 2006 Share Posted May 29, 2006 Whats the normal water temperature range of a BPU supe? I just wanna know what temperature will mean bad things really Link to comment Share on other sites More sharing options...
chilli Posted May 29, 2006 Share Posted May 29, 2006 well if your talking stock gauges, mine never moves from just under half way regardless... not sure what that is in degrees C or how accurate those standard gauges are though Link to comment Share on other sites More sharing options...
Guru Posted May 29, 2006 Author Share Posted May 29, 2006 No not stock. I have the Apexi stand alone and an Apexi gauge so need exactly. I think middle is around 90C but just want to know what high is (and what death is) Link to comment Share on other sites More sharing options...
bignum Posted May 29, 2006 Share Posted May 29, 2006 well 100 is boiling point so you would be boiling over, i think your oil temp is as important.90 is about normal running temp though. Link to comment Share on other sites More sharing options...
Pixelfill Posted May 29, 2006 Share Posted May 29, 2006 100deg C is boiling point, but not if under pressure. Under pressure the boiling point of water increases. Mike Link to comment Share on other sites More sharing options...
JohnA Posted May 29, 2006 Share Posted May 29, 2006 well 100 is boiling point so you would be boiling over,.... where did this come from? Apart from the system being pressurised (as said), the coolant mix has a higher boiling point compared to pure water. Anyway, I've never seen my gauge go further than 1/3 of the way, and I've pushed it a lot. If yours goes halfway or more, you may want to do a good flush.

Digsy Posted May 30, 2006 Share Posted May 30, 2006 I'd bet that 99% of the Supras on here have guages that sit at exactly the halfway point. Everyone knows that the Supra temp gauge is pretty useless (or the cooling system is very very stable). 120deg maximum coolant temp is a good figure to work with. It isn't a modern, high pressure system that we're talking about. The stocker is only 1.1bar and I think the "uprated" rad caps run to 1.3 bar?

Soonto_HAS_soop Posted May 30, 2006 Share Posted May 30, 2006 Mine is BPU++ (according to MKIV.COM) and mine sits around 85-90 on a run. That's with a standard Rad, FMIC and Oil cooler in between the Rad and FMIC. Link to comment Share on other sites More sharing options...
Ian C Posted May 30, 2006 Share Posted May 30, 2006 The E-Manage Ultimate datalogs the stock water temp sensor, which is great, but unfortunately the calibration is miles off so it reckons my car runs at just under 60degC - hmmmm I don't think so However, these datalogs are good for watching how much the temperature varies, and it's not by a lot - 2degC. That's with hard acceleration, housing estate tootling, 50mph traffic and 90+ cruises. Is that implausible or just the sign of a good cooling system? -Ian Link to comment Share on other sites More sharing options...
foodfreak Posted May 30, 2006 Share Posted May 30, 2006 My R-vit logs both water temp. & air intake temp. on a cruise( 80 M.P.H) air intake temps are around 20-25c water temps are 90-92c med-heavy traffic (20-30 M.P.H) air inlet 35-40c Water 94-96c John Link to comment Share on other sites More sharing options...
Guru Posted May 31, 2006 Author Share Posted May 31, 2006 Thats cool thats what I thought. I get 90C virtually anywhere anytime. I only see higher when I drive then have the engine off and come back to her..... Link to comment Share on other sites More sharing options...
