So just so I am clear when you stated during the dyno runs the water temps were around 68 degrees (I believe) and the IAT's were 122? How much did the water temp rise during those runs?

Wish something like this could be done for lowering trans temp. A tran cooler is only good to about 20-30 degree's. Hotlapping just kills a trans and it takes to damn long to cool them off!

anything in the works SC2150

I am not sure where you got those numbers from.... but the water temp is normally close to the IATs. So if the water was 68* the the IAT was prolly 70*.

On the dyno runs IIRC I got the water down to about 55* and it rose to 110* and the IAT was 60* and rose to 110-120*

For future......please read the information posted previously instead of asking. There is alot of info in this thread and is not easily remembered and when myself or anyone else pulls numbers off of their head.....well that is how things get misleading and out of hand.

Im not sure where you are getting this thats not my experience. I see the ICWT stay low enough not to worie about it. In fact The GTO came with big tank that sits on battery. I want to change it to the small tank they use in kit now days.

I have read every post from when this thread started last year.

When you had posted your results (page 14 or 15) you showed the starting ICWT and the resulting IATs during the run but you didn't post the water temp after the run. My point was to my original post last night is that water temp seemed to come up drastically (50 degrees in a 10 second dyno run) and my feeling is that there is not enough water in the system to absorb this amount of heat.

I understand on a 1/4 mile run this is not an issue but could be a big issue on a road course if the chiller is unable to bring the temps down quickly enough. At that point you would need a larger capacity insulated tank to help disperse the heat or possibly a larger chiller... just a thought.

He just stated the water temps went up 50+ degrees during one dyno run???

My thought is that if you are going down a straight away and the ICWT reach 110 and then the compressor kicks on in the corners it is not going to have much time to cool the water. On the video it took 3 minutes to drop 40 degrees, my concern is will the water temps keep climbing and climbing after each additional lap.

on the dyno runs the A/C was turned off, so it was not cooling anymore. On the roadcourse you would have it on the entire time correct?

I just added to post 450, my concern is that after each additional lap the chiller won't be able to keep up and that the temps will continue to climb after each lap. Depending on the layout of the track the compressor should kick on for 5-20 seconds at a time in the corners then when you reach straight aways it will kick back off when going above 4500 rpm or WOT and build heat very quickly.

actually when we dynoed with the compressor on one time it would kick off briefly and back on for the rest of the run (it came back on around 4800 or so. We could see the dip in the graph when it kicked back on.

I would think you could retune the setup for a road course so it would stay on longer.
