Well, I have never posted a "build" thread in the past - it will serve as my re-build as my car has been running for some time. Something that might be interesting for the H20 folks is a performance based cooling system - oil included.
The silver lining associated with the engine down is I have been intending to make the cooling updates for well over a year now. Its such a PITA I have delayed engagement. LS engines are notorious for running high oil temps on track - GM will tell you it is ok - I believe it is not. Likewise, mid-engine cars have a notoriously difficult time controlling temperatures simply because of the location of the engine and cooling systems. This is exacerbated with additional power. I walked the pits of the Walter Mitty Classic at Road Atlanta last year and took a bunch of pictures. All late-model mid-engined prototypes used Water-to-oil heat exchangers in lieu of oil-to-air. It adds a serious layer of complexity since the coolant now has to carry the burden of dispersing allot of extra energy. That is what I will be updating: all lines, the radiator, shroud addition, coolant distribution chambers, etc. One of the benefits of this new system is the ugly-as-sin rooftop oil cooler scoop will be eliminated (not to mention the drag that thing is causing ~ slowing me down)! Just remember, along with most other members here, I ain't no "Tygaboy"! (IMG:style_emoticons/default/bye1.gif) Tony |

The volume is not necessarily the same - the two circuits operate on completely different pumps and pick-up sources. I just do not understand where you are drawing that parallel from...we are installing what should prove to be a far more efficient radiator.

T Because it's a fixed amount of oil in a closed circuit and I'm assuming you will be cooling 100% of the pumped oil. I think you're over thinking it. Fast in a little tube cools better than slow in a big tube when capacity is equal. |
