Successfull Tracking with Forced Induction??

theaudir8fan

FI on track is defiantly doable, the only thing is what type of tracking you are going for, personally i can't just go out for hours on, most of the time i just go out and do around 10 laps and go back to the pits to let the car cool down. Plus most of the time, brake fade is the main reason for going back to the pits for cool down. However, if you guys are the type that go out and keep on driving hard for more then an hour, then i say more cooling is defiantly needed. So far on my HR, with outside temp at around 77F, i have seen my oil temp go as high as 279F, that's the highest record on my blitz. This is with the 19 row oil cooler from GTM. I do live in a cold place tho, so for those of you in the south, this might not apply.

CSF, for the Radiator for 7 speed Trans, is there any way we can get something bigger than a 7 row cooler that comes with the Radiator? Can it be upgraded. I am a GTM SC stage 2 on a 7AT platform and would like additional cooling on top of my 19 row trans cooler.

CSF Inc.

The original Nissan unit has a 7 "plate" type oil cooler. We initially wanted to put a larger cooler in there, but it was the largest we could fit in the end tank. This is when we thought about the idea of putting a cooler in each tank for double the oil cooling capacity, but we didn't know if there was a market demand considering that everyone was already buying an external oil cooler.

how much would the price jump if that were to be tabbed up.

You didnt get the 25 row?

apparently the g37 has some room issues lol..

I track my tt 370 and the temps are a problem in more then just the engine also. I boiled the diff oil and it spewed out onto the track and I didnt even know it was happening untill I got under the car and saw it. No problem I bought the nismo diff cover and it helps but it still gets pretty hot. The engine temps Iv never been on a long track with long straights that you would stay on the boost constantly but the tracks here the most iv seen is 245 oil temp. It does get a little tricky when gassing on it out of a curve because so much power comes on so fast I almost lost it a couple times. All in all none of the supercharged 350s or turbo 350s stayed up with me so I think it was pretty successful. Then again im new to the whole road course thing. As for the drag strip it was pretty cold out and the temps stayed down even when I was just about hot lapping. I have a video on youtube of me on a little road course. The other thing is sometimes when the gas got low on a hard turn it would starve itself of fuel but would regain quickly but it would make a spudder. The turbo was much harder to get used to considering the super chargers were much more predictable but all in all I had a blast. The 370 really isnt that hard to make a car you can take to the track every now and then. I have a 34 row oil cooler on my tt and thats it. If you really want a serious car to take alot itll take some extra work if you want it to be reliable.

cf radiator will be here friday.

From 190f cools to this low on the freeway with 45f outside temps

Mike@GTM

I know we have a thermostatic kit on the way to you, but in the meantime, you could always cover the oil cooler if you are concerned with the temps dropping too low.

That's what I'm planning on doing this weekend till that part comes in. Idk how much longer it's going to take to get it to me but i am being patience at the mean time.

Wouldn't the electronics box on the lower fan shroud (top picture) be better off mounted against the flat radiator portion that has no fins in-between the two fans? Odd to me to place it such that it impedes airflow given the room you have. Edit: just realized those are OEM fans so I am sure this was not a GTM design decision.

Along those lines, it's interesting to me that so much of the back is blocked off so such that air can't freely flow through. You would think that this would really impact heat exchange efficiency. Perhaps the action of the fans more than makes up for that. Very nice looking kit in any event. It is about 2x what the CSF kit costs so I am curious what the performance difference is.

The idea is was to allow an option to run the factory fans if desired. We also have an option to run a pair of larger 14" fans.

In regards to "blocking" part of the radiator, the factory shroud does the same thing. That is to allow the fans to draw air through the radiator more efficiently.

Our radiator is 70mm thick compared to the 30mm thick alternative and 18mm thick stock radiator. Running a much thicker radiator core increases coolant capacity as well as increases heat transfer. This also allows us to run a substantially larger auxiliary heat exchanger in the end tank for better oil cooling (trans or engine). Basically, the heat exchanger in our radiator is large enough that you don't even need to run an air-oil cooler on an automatic transmission...it does a spectacular job on its own.

OK, so the two questions that I think are most important are:
1. Can this radiator support FI oil cooling (assuming no Auto) without an additional air-oil cooler? You seem to suggest that, but I am not sure if that's talking stock car or FI car.
2. Where is the AC condenser? Is that the black, smaller radiator in the pictures above? And if so, where is that mounted?
