What tranny cooler is everybody using on a dragster without getting hot. I recently busted a b&m flat style cooler and changed to a b&m canister which hold 3 xtra quarts and still got hot. Would it be in trans or convertor causes heat or what steps do I need to check and eliminate. In a dragster with 498 bbc with cooler mounted to trans with small fan on it.

I have the canister and that definitely isn't the solution. It is fine for the rare times I use my dragster, but I don't think it would want to be double-entered all the time.

I run both the B&M trans cooler and the canister. I don't usually get hot unless I'm still doubled up in the later rounds with little to no time to cool. In that case, I have the jones cooling system to cool it in the lanes.

If budget allows the Jones cooling system is a good investment.

as far as the cooler goes, get the biggest one you can fit in the space and it should have it's own fan.

I have a regular old b&m stacked plate cooler with a fan. A few weeks ago two TT and 7 rounds varied from 124 to 164 staging this is in high gear only. I do cool the converter with a leaf blower when the rounds start going fast.

Large stacked B&M unit with fan mounted on top, I run the fan when the engine is running and try to keep the fluid cool. -6 AN lines from trans to cooler and the trans is modded to allow a bit more fluid pass through the fittings. I can normally keep in the 150-170 range. Also use a 50/50 mix of F and Synthetic.

This is what I run and it has worked well. My transmission guy told me often if you have a ringless input shaft they will often run real hot because they do not circulate fluid through the converter very good where the heat is created. I am lower power so do not have to run the ringless input shaft and have no problems.

Not a dragster guy but going on three years in this ride without a cooler and no issues. Having said that I will be changing trans next week.

How hot is too hot and where are you measuring?

Last time out I saw a peak of 199 in my canister and 215 in the converter. Measured with a gun. I feel like that is high but not too high.

Too hot is when the clutches start to slip.

Not dragster but I'm my car I double alot.

With Jones cooler I can take my 210 degree trans to 160 in about 6 to 8 minutes.

For those with racepak or dataloggers most of the heat I've seen is on the return road. Going down the strip my car gains only 2 degrees typically. On the return road it will climb 35 to 40.

When I hit the pits or Lanes in late rounds I just got the pump and fan and let it do it's thing. Shut it all of at 160... And repeat.

Without it later rounds I was always around 190-200.. Up to 230 at times.

I haven't been running a cooler but installing a Shogun can that I have before I go out again...I also put a fan on the converter in the pits....Never had an issue with trans temp though, even running a ringless shaft....
