2020 GT full Hellion build

[80FoxCoupe]

Totally get trying to keep everything cool but I'm struggling to see how coolant lines to the wastegates will keep anything cool? Other than maybe the diaphragm inside it? Seems like senseless extra lines to run so I'm just trying to wrap my head around it. Clearly turbosmart added them for a reason but I don't see it....

You already acknowledged the purpose of coolant flow thru a wastegate. It's a mechanical device utilizing a rubber/nomex or whatever diaphragm on a glowing red hot exhaust pipe. Engine coolant temp can be potentially 1000deg cooler that the exhaust gas. Your application likely does not require this cooling. Do a bunch of standing mile runs or road racing, then you may need it. A rip on the hway or even 1/4 mile racing doesn't require it. I'm sure you would see water on wastegates on any rally or road race car.

In between track outings, my goal is to be able to take the car on 3-4 hour road trips and have everything remain in check while not being overworked.

It will do that easily without coolant running through the wastegates. To me, it's just another chance at having a leak. I wouldn't do it unless I had a car I was road racing.

Don't take this as negative, but it seems you over engineer and make everything more complicated than it needs to be. Sometimes less is more.

I sure hope no leaks come from this install anywhere, whether it be boost or fluids, as I hate leaks. I‘m just looking for reliability and durability that will let me drive the car as far as I’d like to without any issues. I live in Florida, so it does get very hot here.

I appreciate your and everyone else’s input and don’t take them as negatives at all. It’s true that I do have a tendency to over engineer and it’s because of past experiences and lessons learned about addressing weak links in my cars/motorcycles. I also enjoy the challenge of doing things that many people say can’t or shouldn’t be done.

Working on my toys is therapeutic for me. I don’t rush anything when it comes to this stuff and will take whatever time is needed to hopefully make a vast improvement. I have a really hard time letting mods go to waste that I’ve spent good money on (my nitrous kit being one example). I would never come close to getting back what I have invested in it to justify selling it and therefore, it will stay on the car with a lower and safer shot being used.

I’m learning a lot as I dive deeper into to this car and as always, will share the good, bad and ugly with others in the spirit of helping them, while also drawing from the experiences of others to expand my own knowledge base.

I struggled enough with trying to plumb the boost controller without melting lines around the exhaust manifolds. I can't even imagine trying to get coolant down there. For me, the risk would not be worth the reward. Hellion insists that there really are no heat issues with their sleeper kit and doesn't even recommend Jet Hot style coatings.

I hear you. Looking at the current mock up of the BL Fab single turbo kit, I can see that it will indeed be a challenge just as you’ve mentioned. I see lots of heat sleeve material being needed to pull this off.

I can already see that fabrication work will be needed for some of the cold side plumbing and intercooler. The kit appears to be a bolt on and go setup, but I don’t at all expect it to be that simple.

Found more of the photos from the advertisement of under the hood. You can’t see much as the turbo’s are mounted below, not top mount. I will get to taking more of the intercooler mount and turbo’s themselves. I need to check the air filers as I am only getting 9.75 psi rather than the tuned 10 max.

Thank you! That's what I was getting at. At what point is it needed enough that risk vs reward makes sense. I take 5-6 hour drives to visit my son at up north in the summer all the time and burn through about 3qts of meth on an average trip so I'm in boost playing around quite a bit. No standing miles or road racing but lots of fun heavy driving. Just wanted opinions of when something like this would actually make sense.

Sounds like you are just making quick 1 or 2 gear pulls with plenty of time to cool down between. That's really nothing IMO. Not to say that water cooled gates wouldn't benefit you. Gates will last longer and perform better in that duration. But it's up to you if that cost is worth the benefit. Just like anything else we do. You paid 10k for a turbo kit, 2500 on fuel system, 1000 for tuning, wheels, suspension etc. What's a bit more? LOL
