Hey Guy, I just picked up my 2017 Gsf and was wondering what the car operating temp gauges suppose to sit at? Both gauges temps is always in the middle. Is that normal? Thanks for ahead for any feedback..

 

Yes, but the oil temp gauge can be tick or two to the left of middle in cooler winter months under low load driving conditions in my experience.

 

Thanks for the reply. Also is a rr racing aos recommend ed even if I don't track the car? It's my daily

 

I'd say its not, since the PCV generally doesn't suck much oil up when normally driving. Take it to the track and you might want an AOS. I personally don't think even for tracking it is really necessary, but I do suppose it does help the engine a little.

 

I have an RR AOS and I see benefit from it even outside of trackday weekends. We have some fantastic mountain roads around here and the AOS collects a fair share from some spirited driving.

Another way to look at it, having it won't cause any harm.

 

Will it void any extended warranty I have with lexus?

 

As long as it doesn't introduce an air leak from faulty connections. I'm not a fan, don't run any catch cans, and never had the issues some claim at trackdays. But I didn't follow the factory break-in either. I know it's a guaranteed recipe for poor ring seal with lots of blowby, and I've proven it to myself more than once.

 

That depends entirely on what you mean by void. It can't void any warranty for anything not engine related, but could cause problems if you have some kind of engine failure.

I'm worries for whatever reason if I installed the app incorrectly and it some how messes up the engine that lexus won't cover the damages

 

Does anyone know if they make ark exhaust for our GSf?

 

Strangely enough, mine runs cooler than most cars I have seen on this forum.
I don't know why...

I live in the Middle East, so as you can see, our ambient temperatures are very very high most of the year-round.

 

The gauges display numbers to prevent owner complaints,

 

THere is no reason that the catch can should cause any issues, if you install it correctly. It is also very reversible, very easily so if you have an issue and need to take the car in, just remove it. I do get a fair amount of oil in mine, but nowhere near as bad as my old N54 BMW.

I live in a state where a catch can would fail me at a smog test. But I’ve heard mixed opinions on them.

Ive read several comments on other forums claiming the catch can actually increases the pressure/blow by so the amount of oil you are catching is more than you would actually have in your intake without one. So it appears more effective than it is.

Anyone know if that’s true?

 

No, it could never increase the pressure. What actually happens is the pressure drops when the gas enters the can as predicted by Boyle's Law. Pressure and temperature are inextricably related by Charle's law, so any pressure drop will also cause a temperature drop. A temperature drop causes state change, so "fumes" turn into liquid and coalesce in the "catch" can which is called a coalescent filter in industry. You can buy one for your air compressor to help remove water vapor from your compressed air, and it uses the exact same methodology as the catch can, with zero moving parts.

So collecting a bunch of liquid (I'm not going to call it oil because I'd bet a whole lot of money it's more water than anything) in your catch can doesn't mean a lot. If you're street driving and filling up one of these things, I'd bet you have pretty high humidity. If you live in the desert and fill one up, something is desperately wrong with your rings.

In a racing application - either at WOT or closed throttle most of the time, there's a whole lot more opportunity to have blowby and therefore different approaches make sense.

I don't run one, and have no intention of putting one on unless my car gets put into track duty exclusively. That's really, really unlikely.
