The CS hood is more purposeful in build & may extract hot air even better (though I'm only guessing), the vent on the CS is much more horizontal & thus is baffled & designed to divert the increased water ingress. I personally went for the GTS hood as I'm trying to create my own version of what an M2 GTS might be (wheels, seats, cage, hood etc). I wanted an aluminium hood as they are much more oem looking imo (underside has all the oem fittings & pressings), aluminium is also much easier to re-work than Carbon if required (thankfully this wasn't needed). The quality of the aftermarket Carbon hoods is also relatively poor from what I've seen requiring additional work before painting. My aluminium hood required virtually no work apart from removing some excess sealant before paint, the fit & panel gaps etc are the same as the factory hood with very little adjustment needed (I do have a very good panel shop which is imperative imo).

The scoop def presses against the DCT cooler. I guess no one’s worried about this bc the most temp the cooler will see might be 225-250F? Speaking of DCT & temps, my mechanic recommended replacing the OEM fluid with Redline. He said it’s solved some hot PDK issues in some Porsche’s he’s worked on. Any input from you guys? Thx. |

Yeah, I just wrapped the OEM rubber gasket around the edge of the aFe scoop hole, and then put the OEM plastic grill piece back--seems like it'll hold fine. |

Hey.
Anyone ever tried to wrap (insulate) the coolant delivery line? My shop brought this up as we recently discussed about the differences N55+ to S55; The main coolant line to the block on the N55 runs very unfavorable close alongside turbo and downpipe (probably the hottest area in the engine bay - maybe for quicker warm-up?) [img]https://i.ibb.co/mC8fxHD/Main-hose-coolant-inlet.jpg[/img] This might be not an issue on stock cars, but they definitely recommend to insulate this line on tuned cars. Anyway, BMW moved this line on the S55 to the front of the block. Could be a quick (and cheap) win for those fighting high engine temps... |

For turbo blanket I was talking to some guys about a b58 blanket and modifying the waste gate section by cutting it larger. but fitment might not be good so a better idea is removing the entire turbo exhaust side and having someone ceramic coat it with heat rejecting ceramic coating, this stuff is super effective and should help keep the heat inside. This might actually yield some meaningful gains on coolant temps.

Does any one know if that's the return line to the pump or is that the feed line from the pump to the block?
If it's the return line I don't think it's worth it. If it's the feed line I think it may absolutely be worth it. And I just had it off when I did my turbo lol |

If you can find anything with a larger inner diameter to fit the coant hose that would work best.

AFAIK my shop uses this (I'm not sure if it's exactly this one): https://www.techflex.org/en/fire-pro...ca-sleeve.html This one is flexible and withstands 980°C (1800°F) long term. I think the 25.4mm variant should fit. The coolant line has a diameter of 32 mm. The compressed areas have a max width of 42 mm. Quote:

So essentially I was looking for a reflective wrap rather than an insulating wrap suitable for super high temps which DEI also sells if you needed it. Also IIRC clearance is super tight so try not to get a wrap that is too bulky or it may touch and now you are introducing conduction into the equation. I would even think a reflective thermal tape would be a really good solution, because like I said I think the major issue is thermal radiation so reflecting would be the best solution. Adding a reflective wrap would probably be even better because of the added insulation but again I don't think the ambient temperatures there would be high enough to make insulation a huge factor - you could always measure temps there to make sure.

Oh yeah turbo blanket, I looked around awhile back and no one was willing to make one. One company that pure turbos worked with made one as a prototype but they were going to charge like $1k for it if you wanted a one off.

I honestly don't think it would get that hot, otherwise bmw would have put more shielding on the water hose. If you ceramic coat the turbo exhaust side all these heat issues will be drastically reduced to the point where a turbo blanket might not even be needed. If you manage to get a turbo blanket on top of that then it would be icing on the cake and overall under hood temps would probably drop alot.

Yes, I´m sure ceramic coating the exhaust side and manifold would help alot. Any idea what costs we're talking about? Probably only makes sense if you want to upgrade the turbo anyway... |

It costs me about $100 locally to get heat rejection ceramic coating for a down pipe, it might cost $500 for the turbo exhaust side. So about the price of a turbo blanket. The only real concern is remov of the turbo and the costs involded in terms of bolts, coolant, oil, and time involved. If you're chasing every single degree it will be worth it.

I get where you guys are going with this, but if the objective it to remove heat from the cooling system in the engine bay I think a better alternative may be a vented hood vs reflective insulation and ceramic coatings.
I got no data on that tho. |

If you could get a turbo blanket that would make a huge impact on under hood temps.

Is there any gains in decreasing the backpressure and lower the egt with an aftermarket turbofold ?. Making the same boost on lower egt. Maybe some stage3 guys can chime in.

You'll get better cylinder temps resulting in lower coolant and oil temps.
