I don't have a cooler in the COPO since we can't cool the engine and blower off fast enough to worry about it, and its a T400 with more capacity. You can be bybassed in the pump and just plug holes as mentioned or loop the lines. I keep a loop on the COPO so I can monitor cooler pressure. |

I have never liked the internal bypass, ours have a small loop of tubing. I replaced an internal bypass pump with regular pump and an external bypass and dropped 4% slippage with an ATI 8" converter. Haven't run an internal bypass since.

Do you plan on winning?
Not trying to be a smart butt. Most time trials and early rounds of stock/super stock have plenty of time to cool everything... sometimes a single round in a day. However, if you plan on winning, then often the final 2 or 3 rounds are rushed, round robin, get it over. Is a really bad feeling to get that far, that close, and have a trans hot and change your reaction time and or time slip...? It happens. I ran without a cooler a few years ago, after having a rubber line on the barbed fitting leak in the waterbox at a divisional race in my 10.90 car. Thought it was the one less thing to go wrong or worry about. Then I lost a race when trans was hot and cost me a few hundreds in a final... stock metric 200 pans do not hold much fluid... Now I run one of the Jegs' coolers, part # 60351 I think. I put AN fittings on it, and all braided line. Very little chance of this style cooler leaking or getting damaged. This along with synthetic fluid keeps things very consistent. Extends trans life also. Just my nickle worth of experience over the years. Good luck. Ken Stock 412 |

Ed, ATI has their own synthetic fluid. Jim has been after me to try some, I've been testing other stuff, I can't give it an honest fair back to back test.

The way I look at this is from my own personal experience.
If you don't plan on going quick, back to back late rounds, either in S/SS or bracket racing, then you probably won't need an auxiliary trans cooler.

Mark, I like your comment and agree. I see no down side to running a cooler and you point out one very positive advantage.

I should add that my car is street legal and will drive to the track as well as run in either GT/ or bracket. Therefore I run a cooler with braided line and -AN fittings. I don't drink beer so I plan to spend as much time as possible with my right foot to the floor.

Personal observation - Any advantage in my case is nullified by my huge swings in reaction times lol. When I go rounds it is usually due to dumb luck on my part or incredible bad luck by my opponents.
