You could just try your existing Mishimoto first. But I’d say the biggest one you could fit and afford if you try another. I trust the Setrab brand, but anything that has decent test data and is over a 948 equivalent btu should work.thanks lol I had thought about going to a larger cooler and moving it behind. What kind of coolers would you recommend?
This is interesting....so it feeds from the lower grill and exhausts out the bottom....is that whats going on here?As a rule I don’t like to locate an oil cooler in front of a radiator, you are basically pre heating the air going through it with an automatic increase in water temp
On my s550 track car I went with an Harrop oil cooler kit that seat parallel to the ground.

Pushing the car on squared 305 on a 103* track day, maximum water temp was 230 and oil 257
The cooler is a Setrab
Yep. You’re 100% correct. And with the removal of the factory oil-to-water cooler, I also removed a huge thermal load on on cooling systemThis is interesting....so it feeds from the lower grill and exhausts out the bottom....is that whats going on here?
With the exception of feeding air to the underside of the car its a sweet setup.Yep. You’re 100% correct. And with the removal of the factory oil-to-water cooler, I also removed a huge thermal load on on cooling system
We’re in the Houston area. There’s an event in august but I unfortunately won’t make it. Hoping early next year.Where in TX are ya? Planning on heading to COTA?
What is your take on the no fan shroud option? What fan do you have?Andrew just copy mine. It works flawlessly in heavy competition and in the heat. Water and oil temps are no issue and I don’t even turn the fan on unless it’s stopped for an extended time. It just works and you've seen more of it than most have. Lol. I didn’t want to lose my hood scoop either but I got over that pretty quick and now prefer the hood louvre look.
Someone can correct me if I’m wrong but as I understand it is this. The air enters the radiator at an upward angle ideally from the lower grille. Especially with large splitters this is the highest pressure zone on the front of the car as the blade is creating big downforce. The air moves through the coolers and exits the center hood vent 2” behind the radiator. This is the easiest flow path for air increasing airflow through coolers while decreasing lift and keeping the front end of the car more stable.Can someone explain the logic of rolling the radiator to me?

Basically it’s the most direct and unrestricted path through.

I have a more traditional setup but very well ducted and I get similar numbers.
More than one way to skin the cat. lol.
EDIT: I'm at 220 water and 210 oil temp in competition. I make 477 rwhp and shift at 8k
That's wild - mine can get up to 260 if not more on oil, 235 on water is a pretty standard figure. If I cork up the exhaust to pass sound, oil skyrockets to 290+ in a 30 minute race and I'll flirt with 260 water temps and the associated limp modes. Half our race schedule in AZ features race times at 95* ambient which is a challenge, but if you throw in a bit of altitude or sound restriction things get real hairy real fast for a lot of the ST1 and ST2 fields from a cooling perspective.Update:
This years motor makes 507 rwhp and after 2 years of wheel to wheel competition my water/oil temps have stayed around 220/210 in all climate conditions.

.576 and 252 duration @ .50 for intakeMy god!!! That thing is still pulling to 8000 mine starts closing down at 7200 :-( What are the specs on your cams?
