I run one but I'm not running a FI TT kit

I'm not sure what size you would need but I'm sure someone that makes them like ptp would be able to get you one that fits well, just give them a call or shoot em an email. I'll probably get a pair, they have benefits such as lowering the temps of the engine bay and the radiant temps around the turbo, thus lowering the chance of a failure, while retaining the maximum heat for the greatest amount of expansive gas and a more responsive boost.
You can read up on them here.

I see turbo blankets used more on the single turbo builds than with twins.

Is there more benefit one way or the other? Besides boost ranges, I always thought a turbo was a turbo, big or small. But I'm no Yoda.

I don't have an good educated answer for you other than my observation on reading all the boosted threads and all the folks I know with twins don't have them. I would surmise that because of the size of the single turbo and as you stated above there are more benefits to single turbo.

I still believe that bagged is better than not bagged. However; if you aren't concerned about heat issues than the benefits are minimal.

They will benefit from them, but top/bottom mount setups will benefit more. There's more inherent enthalpy loss in a setup that places the turbo farther away as opposed to one that keeps them tucked up close.

I'm more concerned about direct line of site melting issues from the insane heat generated from the hot side. On a factory NA car there is minimal shielding because they didn't design for turbo levels of heat. I didn't bag for any performance reasons. Of course I went full retard on heat management all over my build. :rofl2:

For Fast intention TT set up, I would go with their provided heat shield and ceramic coat both the exhaust manifolds + the turbines.

Didn't realize they provided a heat shield. That'll definitely help. All you need to do is break line of site.

Ceramic coating is not going to help much. Wrap is better. A buddy has all his piping ceramic coated and after two years you can definitely start seeing that heat is doing damage to connectors and such. Went ahead and header wrapped the hot side to prevent any further damage.

Yeah I'm more concerned about hot spots on the engine more than performance. A big reason for gasket failure is hot spots I've read. Also, everything else close would be more subject to melting.

I'd still grab all of it. Ceramic coat and bag em. Especially considering the location of the turbos. This isn't just FI's kit either, most the kits out there have the turbo running just off the manifold but the Z turbos are a bit tucked away under everything, giving me more reason to grab a bag.

I know when I go boosted I will do ceramic and bags. I prefer overkill.

Extra heat shortens your engine's life and kills your components underneath the hood prematurely, particularly the wiring harnesses.

The 370Z is engine compartment, for some reason, is notorious for trapping heat. That is one of the major causes for high oil temp. One of my colleague has a 2013 EX37. Same exact engine set up, same exact radiator capacity and same exact fan temperature PCM codings ON/OFF durations as the factory 370Z.

Even on a real hot day for the EX37, on normal stop and go and occasionally hard drivings , the oil temp never went above 220F, where as my Z in the same condition can shoot over 240F easily. I am comparing both without oil coolers as they came originally.

So, TT the 370Z makes it very vital to keep the hood temp as low as you can. In addition to ceramic coating, I probably have to think about ventilating the hood somehow, or install a good carbon fiber one with nice ventilation built in.

There is no dry carbon fiber vented hood out there that I know of. That's precisely the reason I bought a spare oem hood and modified it. Lighter than any vented hood on the nsrket
