Hey all,
so it's become obvious to me that I need a transmission cooler set up. With 330 hp and using a 901 box, it's going to start destroying gears (already did this past weekend at Road Atlanta). So, what is everyone using and how are they set up? What pump & cooler? are you using a resevior/tank? Where is the cooler mounted? and where are you getting the oil in and out of the trans? As you can see, I'm a complete newbie about this, need to educate and do as quickly as possible...I'm running out of transmissions! Pictures would be wonderful... thanks!! |

Ron,
Sorry if you mentioned this type of info earlier, but on your trip yesterday, you mentioned an approx 15 degree delta when you run the pump. What was the temperature you were seeing when at steady state highway cruise without the pump on? Thanks, Richard |

Sorry if you mentioned this type of info earlier, but on your trip yesterday, you mentioned an approx 15 degree delta when you run the pump. What was the temperature you were seeing when at steady state highway cruise without the pump on? Thanks, Richard It varied from ~150 - 180 depending on my speed. That's less than the temps that I saw on the previous transaxle (lost the R&P late last year) and the main reason I'm going to plumb another sending unit closer to the gear cluster/R&P. It might get the same readings but I'm just not sure, and tapping another hole for a sender is trivial. Until then I don't know if I'm comparing apples and oranges between this box (same internals except for the replacement R&P and a taller 5th gear pair) and the last one, which ran hotter ~200 without a cooler. All bearings are the same. Interesting to me that it took about 5 minutes at ~2.x gpm flow rate (didn't measure it hot) to bring down the temp. I could've calculated that beforehand but chose to just observe the finished system. This geared pump is rated at 2.6 gpm continuous duty. Another thread that, but important. |
