Turbo blanket
anyone running or looked at any turbo blankets? I find with the intake being right over the turbo it could be a little more efficient if I bring those pre turbo temps down a bit. I was looking at these guys who seem to have a decent offering: https://funkmotorsport.com/product/m...et-b48-engine/

I want to get a downpipe at some point and considered a coated one and doing a little heat management in the area, but haven't considered a turbo blanket. Seems like something that'd come after an intercooler upgrade. What real world impact do turbo blankets have on spool time in general? I'm curious to research this.
Thank you so much for sharing this link btw. As someone with a Melting Silver Metallic car, I am obsessed with the aesthetic of this, and the company in general!
Added to the parts list lol

I have only recently started looking into it as even with my upgraded intercooler it felt things could be better. I have heard that keeping the housing hotter increases spool response etc but I have not dug into any practical theory. For the price I might just give it a shot anyway, it just sucks the turbo is between the firewall and the motor hindering access a bit. I removed a bunch of the plastic / padding between the firewall and the motor and it seems to have made things quite a bit more accessible but at the cost of things being noiser in the car. I can really hear that hpfp and the injectors from in the car now.

From what I've learned, the efficiency of the turbo is based on the delta between the "hot side" and "cold side", and its durability is based on the cold side staying cold. If the hot side is hot then air moves more quickly which spools the impeller faster. If the cold side is cold, more air gets in faster since it's denser, plus the oil and bearings experience less extreme heat cycles and wear down less.
When people measured the effects on spool time with a blanket in the multiple videos I watched, the improvement seemed to be 250-300 rpm earlier for one bar of boost, and in the one research paper with a large V8, there was 140 Nm more torque at a given acceleration point.
Some turbos have heat shields in between the sides for this reason. A blanket is a vastly more effective solution at a vastly higher price.
Then of course because the turbo can otherwise get very hot, blanketing it keeps other parts cool such as intake, oil, and coolant as you alluded to. I could see you being right, since you could drop 400-500C down to 50-100C right below that intake (there's a valve cover heat shield but don't remember what there is for intake so maybe the delta would be less since you'd be improving over an existing shield).
