That bypass delete is interesting. I guess with the t stat removed, you need it. Never really thought about it. It would be interesting with a t stat and without with that plug and see the temperature difference
That would be an interesting test. Since the car only takes a temp reading from one spot it would be difficult to get accurate information though. My only concern would be potential hot spotting.
I didn’t know about the coolant block off pipe at the water pump. Was thinking it was there for a reason but couldn’t find any info on it. Should’ve welded the water neck and water pump housing shut while I had it off. Maybe will take it all off again and just weld it shut. The walls in the housing itself have scratches and I don’t want it to leak later also. Haven’t run engine yet, still mocking things up.
Yes, Sir! It’s from PHR and a lot of the guys that run partial fills will use them to keep coolant temps down with the reduced surface area. I was curious to see how it works with a non filed block and may revert to stock depending on temps. My only concern for running on a non filled block is that the oil still needs to get up to temp in order to burn off moisture and contaminants. If it doesn’t, I could easily spin a bearing. 😬 I’ve got an oil temp gauge installed in the relocation plate to track its progress. After the car is running again I’ll take it for a quick 30 min drive. If the oil temp doesn’t get to at least 200F then the bypass is getting pulled back off. I’ll keep you posted though. 🙂👍
@@s302jzget I opted to switch to the PHR low temp thermostat instead. After discussing it with a few other Supra people, the general consensus was that the oil wouldn’t get hot enough to evaporate any moisture it may have accumulated which could then lead to bearing damage.
I might have missed it in the vid, but I know of the t-stat delete kit from PHR, but is there any downfall on startup (cold engine) to using the delete? Only thing I can think of is the engine maybe not coming to temp as quickly, other than that seems like a benefit all around. Can you shed any light on that?
I’ll have to let you know how it responds once the car is back up and running. You’re right about it not coming up to temp as quickly. The only other drawback I foresee is the car using more fuel in an attempt to get the operating temp up. We’ll see how it goes though.
2JZ Addict yeah will be interesting, I can see someone making a claim of more engine wear due to being ran at lower temp for longer, but in my opinion that would be pretty far fetched lol.

@@2JZAddict any feedback on this?

Are you running the IS 300 fans and shroud?
Yes, Sir! 👍🍻
PHR makes a really nice IS300 fan kit
