  1. I think on a commute on a warm (over 20C) day with stop/start driving plus some 50-60km stuff, it will get to 85-90C or so, but then the fan kicks in and keeps it in check. It was just at the track there wasn't any airflow to or away from the fan/cooler so the cooler was sitting in a hot box and couldn't evacuate the hot air. With the undertray in place and all the other plastic covers etc - it's pretty sealed in there. Yeah I'm thinking the 105/106C I saw was not what caused it to go into limp mode, and it was probably the engine oil overheating that caused it. Which seems crazy that it happened so fast - 5 minutes on the track is all I would get without having to do a cool down lap or two.
  2. Great write up! I have done something similar but am getting up to 106C on the track and the car goes into limp mode until things cool down. I assume it's the trans temp that's causing it to go to limp mode. Although at one point I also got an engine oil temp code. Have you thought about putting a louvre style vent in the inner guard to help evacuate the hot air? I haven't done that and my inner guard is super hot at the track.
  3. How long is a piece of string. Depends on their offset as well as overall width. I'm running 245/35R20 on my FGX on an 8 inch rim and they could with 255 or maybe even 265. Sent from my LYA-L09 using Tapatalk
  4. So now I'm undecided. I can only afford to get 2 tyres before my track day. I have 2 with half tread on the car at the moment and 2 that need to be replaced. Do I put brand new tyres on the front and put the lesser quality half worn ones on the rear, or the other way around? Sent from my LYA-L09 using Tapatalk
  5. Ok thanks. I'll stick with 245's then. Thinking of Michelin Pilot Sport 4S Anyone know if these are accurate width wise? You'd hope so for their cost!
  6. Thanks. Got it working. Any suggestions on a vent/louvre for the inner guard to vent the fans hot air when you mount the trans cooler under the drivers headlight, inside the bumper space? Bunnings has a crap selection.
  7. That's what I thought. Inside the rim it says 8x20" though. I wonder if the cheap tyres that are on it are not really 245's as they say they are. Cavallis. Heard of them on a car? Nope. Me neither haha. They were on the car when I got it.
  8. Hi all. I have 8x20" rims and have 245/35 tyres round. I am about to buy some new fronts tires and will probably just get the same size again, but for the rears, I wonder if I can go wider on the current 8" rims? The current set looks slightly streteched at the moment to me. But maybe I don't know what I'm talking about?
  9. Howdy. Tried uwing Torque app adding the trans temp. There were 3. Two of which gave no reading and one gave a minus 40C reading, increasing to minus 35C as it warmed up while the car idled. Weird.
  10. Haven't tried Torque app. Will do tonight! Will the free version work or do I need the full paid version? Do I add a custom PID or is it smart enough to do a scan? Cheers Hunt
  11. Hi Andrew. Thanks for that. I will monitor temps and try again. My OBDII tool doesn't connect to Forscan and the other random OBDII app I tried to use was telling me the trans temp was 176C.....yeah right. I don't suppose you were able to export the stats from that trip? I wasn't thinking just slots, I was thinking a louvre design to angle the air down, also to prevent the tyre from flicking dirt/debris at the cooler. You're right, hot air over one tyre may not be a good thing. Not sure how else I could vent it though. There isn't any air flow inside that area, especially with the lower undertray on. The inner guard was VERY hot when the fan was on.
  12. I've just installed mine with a fan under drivers headlight. There is no air flow though so with the fan on, blowing backwards, the inner guard is COOKING and I imagine the cooling effect is minimal. Thinking of cutting some slots in the inner guard. Thinking of making them like a louver vent so the wheel doesn't flick crap into them. Not sure how to go about this. Any tips?
