HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Is there a preference for a 165 deg or 180 deg stat? Is there any accepted thinking on the choice of temp for an LT1. If lower temp, is there some reasoning. I've searched and couldn't find any definitive answer.
Thanks

I'm going with the 165 deg stat and programming the ECU to run fans.

If it is street driven, stock temp is fine. A high flow tstat would be a plus. With these cars some find that the cooling system is not sized well for the V8. If that is the case then a low temp tstat will have little impact as the system temps will run high anyway.

LS1 motor - I have a 165' t-stat, an all aluminum radiator that is basically a stock replacement, Porsche fans, computer set to run fans on 200(low). in 85-90' weather I run 195 on cooler days down highway it runs cooler than that.

Thanks Gdopnt: I have an AL radiator from Evans and the Porsche fans as well. I'm going with the Hi Flow 165 deg stat. I'll probably set ECU for 200(low) as well.

Stock 96 Vette LT fan settings are:

low speed fans ON at 104°C (219°F) and OFF at 98°C (207°F)
high speed fans ON at 109°C (228°F) and OFF at 103°C (214°F)

IIRC the stock thermostat temp is 180. If you go with a lower temp thermostat, lower the fan settings to match.

The 96 has dual fans that are both running for either low or high speed operation.

Erm....i'm running a 165* T-stat, stock 87 944na radiator, stock cooling fans. Didn't touch a damn thing and she sits perfectly at 190* using stock cooling fan triggers etc.
