First time at the track.....

Had so much fun. For anyone who had never done this before YOU SHOULD GO. I just had a couple of questions. As you guys can tell my NX is turbo, GTiR engine and I only ran stock boost 8-9 psi becuase I didnt want to run too hot. I am running a KOYO rad with 2 pusher fans (had the flex-a-lite as pullers, but does fit with the koyo rad tubo is touching it), nismo thermostat, took out the turn signals to let some air in and bypass fan switch (fans were on the whole time I was on the track.

The track was 1.35 miles, For anyone here with a NX doing some road racing how hot is your water temp during and after a 15 min session?
How else can I better my cooling with out cutting up the bumper and a vented hood?

oh shit! not bad man. time for an oil cooler

Congrats! Enjoy you new addiction.

Are your running aftermarket gauges?

Without the oil cooler, I couldn't run more than 10psi of boost for more than a couple of laps at a time before hitting 230* on the coolant and pegging the 300* gauge on oil.

With the oil cooler and a Koyo-sized radiator, I was able to go flat out at 20psi for 20 minutes at a time and not overheat the motor (200* coolant, 230* oil). The tires and brakes (225-45-17s and AD22s with Hawks) were a whole other situation though.

running an oil cooler involves an thermostat correct? What would be an ideal temp and where can I get a themostat for an oil cooler? And where would one put an oil cooler?

Most every T-stat involved with an oil cooler is set to open at 180F.

You either use a sandwich plate (between the block and oil filter) to run your oil cooler or an adapter plate to run a remote filter/oil cooler setup. Just search "oil cooler" under the roadracing section for some good writeups.

I put the cooler in the foglight hole. I run a Mocal pump with -6AN lines welded onto the oil pan. I have a write-up on here somewhere...

^Is this mainly for turbo guys when they up the boost? I plan on tracking my daily in the future some once I get her the way I want her.

Depends on how fast you are. As a beginner, you'll likely not need it, just keep an eye on oil temps. I'd start there and upgrade as you get faster.

Speaking of temps, how high is too high for coolent? I have the temp sensor in the upper radiator hose...

^Would I just be looking to get the oil and water temp gauges N/A?

215* is time to back off and not rev above 5-6k rpm. Above 220*, time to cruise in 5th. Keep the speeds up for airflow, but definitely back out of it.

Water temp should be fine for NA, unless you're really wailing on it. A good synthetic is a must, as is an oil pressure gauge.

For water temps I usually start backing off at 225F, have been to 245F a few times but wouldn't recommend it. Of course oil was at 270F at this point :eek:.

I have a water temp switch that will turn on a light above 225F... I've yet to install it, but will be a nice reminder when I'm getting to warm :).

I tried looking for your write up but had no luck, do you have a direct link? :confused:

I made it a long time ago. It's fairly straightfoward though. Get a Mocal self priming oil pump, mount it somewhere, and run it off a relay slaved to the ignition. Weld two -6an fittings (or whatever size fittings your cooler comes with) onto the oil pan (with the feed on the back, below the axle, as low as possible, and the return on the side below the crank pulley). Run -6an lines (or whatever size fittings your cooler comes with) to the oil cooler, which is mounted behind the foglight hole (or in front of the radiator, up to you). Mount it with some angle aluminum brackets and make some sheetmetal ducting for it to force the air through it.

I'd also cut slats in the splash guard to allow air out (or duct it out the side of the bumper or the bottom of the splashguard). If you run the slats in the splash guard in front of the tire, make sure to put some metal mesh on there to keep the rocks off of it.
