Forced Induction oil temperatures
 

I decided to go with GTMs TT kit. Obviously it's a must to go with an oil cooler, has anyone ever done twin oil coolers to maintain oil temps down? What are the forced induction guys experiencing?

The other day I was hanging out with a friend's TT Z ( GREDDY ) and oil temps were getting up to 260 degrees! of course he was driving it hard, but that's unheard of. I can only imagine if you track the car!? any ideas? solutions? I want to make sure the install/project gets done right.

Thanks!

Oil coolers are all about surface area. You can run 1 large cooler or 2 smaller coolers and have similar results. If you have an intention of tracking the car with TT then you'll want the largest cooler you can get which is currently the AE Performance unit.

is AE performance the most aggressive and efficient setup for forced induction though? I thought maybe twin oil coolers with 8 quarts of oil might be a better setup... any ideas?

If you can find the space to put in two 19 row coolers inline, that would be your best bet as it would start getting more difficult to fit larger units inline. Additional oil capacity is good for extending oil change intervals but if you are pushing FI power and are driving the car hard, that extra oil will get just as hot as the rest.

Two 19 row units will have less cooling capacity vs the 1 AE Performance unit, it's the biggest cooling unit around. Look at the specs for all the cores, I did my research.

Yeah, the AE oil cooler is very large.
Also, what size oil cooler was your friend running on his TT setup? I would suggest if you are going to do forced induction I would look at anything larger than a 19 row cooler.

I have an oil spacer, Competition 25 row and we are not having any oil temp problems but mine is SC not TT so not quite as much heat generated. It takes 7.5 quarts and I track my car and never get above 230 in 90 ambient, haven't got to run in the 107 currently plaguing OK.

Yeah, I think the 25 row Stillen would be just fine for a street TT setup as well but given the extra heat it does produce I think an even larger core is a good idea if you are tracking. Plus he is in FL where Summers are brutally hot and humid.

you also went with the GTM kit so there for your temps shouldn't reach as high as his even if you had the same exact setup. Unlike the greddy kit the GTM one really doesn't use the oil to cool it down. It uses the oil to lubricate the bearings and the coolant fluid in your car to cool its self. This is one of the big reasons the gtm kit shines over the greddy kit.

You are definately right, my bad. I just checked it out and you are not kidding, the AE unit is massive!

I am running a 24 row oil cooler and I am usually at 110 celcius. TT'd

Im in orlando fl, and we are currently getting 100 degree temps in mid afternoons. Regular driving stock anout 215 225. I need the best cooling option.

I am located in the super heat of Houston TX. I have the GTM competition oil cooler and my temps never go over 195 or 200, and may I add this thing is huge. I have gotten it to 220 but thats cause I was ripping on it really hard for about 10min, and at the time I had a real rich tune for 91 oct instead of 93. Im sure now it would go up a little higher on agressive street driving conditions now since the tune I use on the daily now is little leaner.

One thing I would like to see though is, the capability to get up to temps much quicker after a cold start. I can drive 20min away to my office sometimes and finally just be getting up to 180-190 by the time I get their. I dont rip it until it reads 180 or more so it makes for a granny drive to the office every day :(

107 deg ambient and driving hard for 30 minutes yesterday and only saw 210 oil temps max mostly around 200. Also had to let the car sit and it would heat soak for 10-15 minutes while reflashing the ECU between tuning changes.

Nice :tup:

Don't expect to be able to track the car with a tt unless you have some insane cooling solution.

My temps tend to stay at around 200-210 max when I beat it in 100 degree weather. I bought my SC partly because of this. TT cars tend to stay off the track unless you have an insane budget. That's just my experience...

:iagree: same reason for my SC choice over TT

just wondering what you guys are getting at idle, my get about 200 on idle, with a hks 15row oil cooler, but thats after like driving for about 10-20min

we are running 14qts of oil in the car and 2 coolers... big gains can be made by addional air flow. On these 100deg days we still see 240 water 240 oil. Just got back from RTA at sebring (very hot) saw 260 oil 263 water!!!! We have beat the hell out of this motor at these temps... tons of WOT and 100s of laps at 12-13 PSI. Zero issues.... Buy good oil... change it after every track event... and be brave :)

Jay is that your son?.... if so he looks just like you :tup: cute kid!

I'm actually kinda surprised your temps got so high. Damn man, even with all that cooling you still were close to going into limp mode.

Guillermo, unless you're planning on spending BIG $ on cooling like jayfightmoves did, don't plan on being able to do a full track session on the TT.

Or you can get an upgraded radiator to help as well. Jay have you talk to CSF or Mishimoto? CSF has a really nice unit out and Mishimoto is looking to develop a unit...

Wow hot temps Jay, the Greddy is oil cooled only. But I dont think that is too big of a factor. 104 side and my temps never got over 195 last week. This with a little bit of aggressive driving. I have never had a problem with oil temps yet. This is a pure street car for me not a track car.

RCZ: I do not plan on tracking the car, might hit the 1/4 though I dont think my temps will be a problem if I decide to.

Should be all good for quick quarter mile sprints!

JB, what cooling do you have that you don't break 195 with aggressive driving?? I have a monster truck spec cooler and I break 195 in 90 degree weather with some aggressive driving..

Wow really! I will even take vids to prove it! Just a comp GTM kit nothing like a moster truck oil cooler. And this is in 100 degree weather, this is with ripping a gear or two every once and while.

RCZ thats because you went Stillen instead of the more efficient GTM kit :stirthepot:

Ooooo, drama. :tup:

Good thread.

Everything is a contributing factor.... We have huge rubber that transfers all that torque back to the motor as well as the increased rotating mass. The increased grip lets us stay WOT longer and get back on throttle sooner... all adding heat. My car is full race so Ill bounce the limiter rather lose the time in the shifts if I'm close to a breaking zone.... that's what really gets it cooking ;)

I have not looked into those radiators. We are however going to change up our cooling once again... so i look into them.

gfy :stirthepot:

real worthwhile contribution bullitt, you are an asset to this board.

awwwwww!!!! :bowrofl::bowrofl::bowrofl: I am a HUGE A*Set to this board Thank you very much! :tup:

:rofl2: you're an asset to this board LOL! :rofl2:

:facepalm: really guys...?

fwiw i'm going supercharger eventually, so i have no idea if the gtm comp will be enough; i would think so, but until then, i'm going to enjoy my NA engine and sub-200 oil temps :tup:

:wtf2:

Would two comp oil coolers help?

What about some dry ice? OR! Move to a colder country! OR Alaska

or how about using a CO2 cooling system on your oil cooler and oil lines that should cool your temps down a bit... if temps get to hot system turns on and super cools your cooler and lines... just some food for thought maybe I could develop a kit or something...

Chit do like the Veyron lets put 16 of those mothers on the car!!!

Just thinking here...

Do they really have 16??? Wow. I am not having any issues right now with oil temps for steet use.
