Our last deal was a hot blooded BBF......staged at 160 - 165 and parked it around 195-200. I used a tick tock switch ( Shogun industries ) ....a sequential switch that alternated the water pump and fan and it would recover in a very short time..........five minutes max. This really helped in late rounds when there wasn't a lot of time between passes. I know new cars run a lot hotter , but I never liked seeing over 200 personally. And a lot of cars just didn't have much trouble with it. I know bow tie guys who could run all day and never get over 180 with pretty decent cars........mid 10 stuff. My Ford just didn't care for it and I did a bunch of things to try and improve it. A shroud would have really helped too if I would have kept the belt driven fan. Big aluminum radiator , Moroso electric w.p. drive , 1,600 c.f.m. fan and the tick tock kept it manageable , but it wasn't exactly optimum. A little hard on the battery , so I had to make sure to charge it when I had time so it would start me in the late rounds.

Back when I was running gas I had a pretty good thing going.
I would burn out @ 180. Leave @ 190, cross the line @ 200, and @ the turn off I was @ 190, and back to 180 by the time I reached the pit.
I have a very large radiator

We have been staging between 130 - 140 running 200ft in the mud crossing the line @ 180 - 190 hitting 200 on the return then shuttin down 200-210, It takes around 4 min to cool off to 100-120 with the engine off and the pump & fan on, We see a 40 to 50 degree temp rise in around 3.5 secs @ wot, I have a single pass rad with a 2800 cfm fan with no fan shroud, Don't have too much room in between the moroso electric pump and the single pass rad around 1/4", The fan is mounted in front of the rad pulling air out of the front of the truck to help clear the rad fins,so I dont run the fan during the pass, I switch it on @ the turn on to the return road, We have been gettin along with this set up for 4 seasons without overheating....But we have plans to run out of state in @ a 300ft track... so its time to up grade,Current rules state cant fool with the fire wall so I can only go forward, Trying to keep the stock grill in place so any one got any ideas

What engine temp do you guys use just before you leave and what is the temp rise @ the stripe? Also how long does it take to shed the temp after the return lane?
I like to see 140 F in the burn out, stage at or below 160 F, cross the line(1/4 mile temps) at or near 180 to 200 F , different motors at different times of the year make a difference As far as cool down time it depends on which car and which track More power makes more heat, takes a little longer to cool down, all comments are about gasoline motors N/A, no power adders and no fill in the blocks either

Spring And Fall click the fan on at 170 stripe at 185-190 stopping cool down at 130 to keep some heat in but in summer fan on at 150 stripe at 175-180 cool as much as possible for the temp and humidity
when i click the fan can sit under 2000 rpm and never see the temp rise even 3 numbers
If I run with a lite load with the fan on its hard to hit 150 even in summer,

With my roadster & 565, the temps were identical to yours

has anyone seen a reasonable drop in load temp with E85?
YES big difference, I have to warm the engine proir to going to the lanes to get heat in it. I heat it up to 160 and then turn the fans on it stays at 160 ! I have tried 140 and 180 but it runs the best at 160.It will go higher without fans but it will stay at the number if the fans are kept on. This is with outside temp in mid 80's we will see this summer when the temps go to high 90's.I used to leave the fans on for about 5 minutes to cool it down after a run and now I turn the fans off so it wont cool down. Best thing no pushing in the lanes just start it and drive it even if you have to sit for 20 minutes at idle. I love it!

Burnout at 150 or so, launch at 160 ... might hit 180 at the turn off and its back to 150-160 at the pit using E85... I see a 20* drop just using E85... its a little harder to get it up to temp so I watch it pretty close in the lanes and fire up to keep it near temp

Why don't you put a larger radiator in the bed. I have done this on a few hill-n-hole trucks here around the house.
One day I will have something cool here.
