  1. If my coolant is 94-95 deg and my oil is 110ish then even if the airflow was as hot as coolant it's still not going to heat the oil. I think it's each sensor having a different heatsoak/thermal latency in the housing they are in. (By which I mean... definitely aliens) One thing I've noticed with the oil cooler fitted though is consistently lower coolant temps, so I'll look through some old logs and see if engine was running any hotter.
  2. Haha. Yeah fan blows in correct direction, when car is idling you can see it pulling stacks of heat out of the cooler and there's a 10 deg drop across the sensors. Instead of cooling system reacing saturation point and fan coming on, car stays at 87deg and fan never comes on. So it's definitely doing something, but I dont have any oil temp data from beforehand to compare to. The sensors are both brand new and using same cal table in the ECU, when car is first warming up they both read the same until there starts being a temp difference across the core. In order to fit my sensors (they are quite deep and bottom out in the AN fittings) I've had to use a 1/8th > 1/4 NPT fitting then a 1/4 > 1/8 NPT back again. So the tip of sensor is sitting in oil but they're not completely immersed so it's possible they're prone to heat soak from external sources.
  3. On the whole time
  4. Haha yeah sweet power now Glenn! Good rev range for powerband too. What else changed about the motor to get you over that 200kw mark? More compression?
  5. Okay so who wants to try explain this one for me? Orange line is engine temp. Red line is oil temp before the oil cooler. Blue line is oil temp after the cooler. At a certain point of track day run, my oil cooler appears to be heating the oil hahaha. I am wondering if exhaust heat is influencing the reading of the "After cooler" sensor, as it's line of sight to exhaust manifold. The "before" sensor isnt line of sight to exhaust as it's on far side of oil cooler adaptor.
  6. Haha for sure. Some of the guys in street class have openly said that their cars are too delicate/stiffly sprung/etc to drive them long distance on the road at all. Trailered to and from events, wof and reg "street class" cars that only ever drive on track haha.
  7. My idea for a combined trackday/camping trip... Hmmmm maybe not the best. It was annoying having tools and tyres etc in the car while trying to go camping, then vice versa for trackday, and just generally speaking a car stuffed completely full of stuff! Had an awesome time at the Riverglen camp ground where Nats was in the Cormandel for a few days though. Superlap round 2 at Taupo was a mission! Clutch Master cyl packed up on the way down. Replacement one didnt fit so rebuilt old one with guts of new one. Then staged injection not working properly so retuned for primaries only. Then i had a session where everything went well! And managed a 1.51.6 which I was really happy with, huge improvement over last time and everything felt great. Rear tyres were getting slippery at end of session at 32psi hot so dropped them to 30 hot. Next session after that, e-throttle fault! Which cleared after turning car off and on again, but I'll need to look through logs to see why this might have happened. But decided to just head into the pits and call it a day. On the whole pretty happy with the weekend, and happy that I made it home alright. But I'll also be pretty happy to just park it in the garage for a while and do some other stuff for a while! It was a weekend of frustrating mechanical issues with a small spritz of success in the middle haha.
  8. Hahaha awesome. Down at Taupo at the moment. I ran a 1:52.6 today which is a fair bit quicker than previous best of 1.53.8. Only had 4 laps too, other 4 sessions are tomorrow and GPS is showing a few corners where there's a big stack of time to cut. Also found that incorrect knock sensor setting was pulling 5 deg timing out of the entire powerband haha... So should feel a bit more lively tomorrow! Cant wait! R888s are awesome I was able to take turn 4 without any braking.
  9. I post things that are interesting to me. Feel free to add me to your ignore list.
  10. I was planning to do the next round of superlap with just a temperature probe fitted to the existing setup to get a baseline of what the oil temps get to. Buuuutttt smashing the windscreen brough plans forward a bit! As I had to pull most of the dash out anyway so it makes sense to get wiring changes etc done sooner than later. I have finished building a shroud for the oil cooler fan and the brackets to hold it in place. Unfortunately the cooler is too damn big to fit anywhere except for ahead of the radiator panel, but I've placed it behind the bumper / numberplate and quite far forward so it shouldnt get too much airflow through the core without the fan going. Also I chose black AN fittings where possible and put some fibreglass heat sleeving stuff over them. Mainly because it looks a bit nicer I reckon. Nearly finished the physical install of it, then just the wiring to sort out. Dad has provided me with a PWM fan controller, it's really easy to setup so that should be cool to have a play with! Markku has loaned me another speedo drive to test with, hopefully this makes everything work nice again and cruise control will be back up in running in time for the next Superlap round at Taupo.
  11. What's the scoop thingy for? EDIT: Nevermind just read that link
  12. He'd have to actually work on some of his projects to improve the ratio
  13. He'll put it in other projects after he attends his first meet in it
  14. I remember someone telling me that these came with an RB motor, but I never believed it. Very cool! Nissan Z cars win at 2 seaters and fails so hard on the 2+2s
  15. Yeah I think I'll keep eyes peeled for a 2nd tank, and then get it dipped / repainted / etc then swap them over.
