G'day all,

I Just installed an exhaust temp gauge in the car, but i cant seem to get it to read past the base number (500 degrees C).

Just wondering what sort of temps i should expect from a fairly stock R33, i had the gauge reading up to around 650 with a gas match under the probe, so it works as far as i know.

Also the probe is installed in the turbine outlet of a split dump, just in front of the oxy sensor.

Any ideas?

Cheers, Bart.

Stop-start city driving between lights (not just sitting extensive idling) 500-550C

Extensive idling 400 drops to about 350

Steady state rolling on/off throttle to stop, up to 80km/h not running big throttle 550-600C

Highway running extended closed loop running 600-680C

Climbing mountain range, mild boost 600-650C

Flat knacker acceleration run 700C

Thermocouple placed in split dump, main dump from turbine just behind O2 sensor.

Some of the cast HKS RB manifolds have a port at the collector , will get faster reaction times if placed before the turbo which does absorb some heat . Some tuning firms like to have them closer to the exhaust ports (by 6) and can help assist tuning on an individual cylinder basis . EGT tells alot about AFR but finding the variation between cylinders is impossible taken at the collector . The laser temp sensors would be handy at the tuning phase .

Cheers .

Can anyone tell me what the resistance of the sensor is cold? I'm hunting a problem at the moment and i'm leaning towards either dead sensor or damaged loom as i've checked everything else.

cheers

Dave

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
