Do Turbo Blankets Actually Spool Turbos Faster? Real Results Tested!

- We all know that turbo blankets keep turbos hotter and engine bays cooler right. But do they actually make our turbos spool quicker and can we measure those results? We find out today on DirtGearTv do turbo blankets actually spool turbos faster? I did my own testing before and after installing a turbo blanket to see if my k03 turbo would spool faster after the turbo blanket was installed and the results might surprise you.

Best thing about the turbo blanket is it can't see you murdering clutches and axles and run away scared.
I had never heard about turbos spooling faster insulated. Great video dude.
🤣 Ya I wasn’t expecting to see an immediate result like this
One thing to consider is load has a huge impact on boost psi. If you compare a dirt data log to a tar data log the tires have more traction and will creat more boost due to higher engine load whereas in the dirt the power makes the wheels spin and doesn't load the tires as much. What gear are the datalogs taken from aswell because if you do a pull in 2nd gear your boost will be lower then if you do a 4th gear pull. Just some things to consider aswell. But I do believe the blanket will help spool a little fast as it's keeping the heat in and the gasses will flow faster and expand or stay expanded longer.
What an underrated video !
So informative and so much better than other channels...
thanks bro 💪🏽
God bless you.
Very informative video! I learn SO MUCH here! You are AWESOME!!
I've been looking at one for my k03. Thank you because this was not only helpful but very informative
Awesome video, tons of information, scientific result explained. well done bro. and thank you.
Ok I've never heard of a blanket spooling faster. Can't wait to see the results
Me either!!👍🏼. Exciting!!!
You've been under a rock then lol
This is a great video👊🏿
GOOD STUFF BRO!!!👍🏼
Anyone who owns a 10th gen civic I got a $30 blanket from Amazon been working good for almost 3 years now no issues with it or my engine. I was skeptical about it but rolled the dice and won to even my own surprise
Be interesting to get a intake air temp b4 & after blanket. I suspect the turbo heating up the intercooler for every degrees deduction increase air density ( more oxygen) maybe a ram air duct blowing on the turbo hot side may reduce turbo temp every thing help when try to squeeze every once of power! Thanks for your time for sharing .
Did you make sure to change the emissivity settings for the IR temp gun for the material you were measuring?
Another factor not as easy to datalog is power. Since less energy is being lost as heat, it needs less exhaust volume to power the turbine. That means less drive pressure - which almost always more power.
Nice video!
Yeah! Great stuff here!!
A turbo blanket is just a material used to cover the hotside of the turbo. In many applications, the added heat from not having anything to cover the exhaust turbine housing produces significant heat for the cold side and any components close by. Thus why many manufacturers use heat shields. More cost effective and still contains heat away from anything else. Now the blanket is designed above a heat shield in terms of it absorbing the EGT produced and dissipating it better. When you do this, you do increase in thermal efficiency which in turn can be used for more power.
Now applications like the Ecoboost 2.7 and 3.5 platforms do not come with any covering for the hot side. It is technically air cooled during motion and has a water cooled exhaust manifold as is.
good idea and subaru - under bonnet heat is down 250 degrees = and keeping the exhaust hotter - yes faster spooling and will notice it on the street !
Ceramic coating the manifold and the turbine along with heat wrapping both makes a significant gain in spool and under hood temperatures. Both is better than one or the other. The wrap/blanket makes a bigger difference than the ceramic coatings, but the coatings are easier to do, look better, and last longer than the wrap/blankets.
thank you for the test...
so turbo blankets improve performance..
how about parts longevity and durability? will there any particular parts that negatively affected?
Anytime an exhaust or turbo gets wrapped there will be a small trade off on longevity as it’s exposed to higher temperatures
You need a bigger intake dia to free up the cold side
Will turbo blanket help even in dune buggy with turbo out in the open no engine compartment?
It deff improved response in open air on the buggy!
@@DirtGearTv Suggestion: carefully insulate every fraction of an inch of the exhaust tract after the exhaust seat.
A) grit blast then clean and paint the inside of the exhaust port with a thick coat or coats of heat-rejection metallic/ceramic or whatever you find is the most effective. Detroit Diesel actually CASTS insulation in their exhaust ports of their 149 series 2-strokes. Porsche used a ceramic shaped insert into their exhaust ports of their 944 turbo. This stuff is overlooked by those less-informed.
B) cover the exhaust tract from head to turbine outlet in a thorough, possibly double-layered covering of insulating cloth, such as the silver carbon fiber available at surf board material shops on Maui.
C) Put the biggest exhaust pipe you can cram into the car after the turbine. No size is too large.
D) Grit blast and/or sand down all surfaces of the turbine snail, then coat THEM with the most reflective heat-rejecting coating you can find, like the exhaust ports.
E) Same drill with exhaust manifold: grit blast then coated with reflective, ultra-high-temp coating, inside and out.
F) Thermal barrier coating on the exhaust port part facing the valve spring area, if it is not separated by a water jacket therefrom.
None of this is rocket science any longer, just ignored and overlooked.
You may want to put a small cooler on the oil line just before the turbo center section for heat management and cool it with some closed-loop liquid cooling or just air. Gotta keep the heat in one place only: the turbine.
The difference between millionaires and trophy winners and the shleps is fanaticism.
Great video filmed from inside a closet...
In a closed engine bay there are huge difference with or without a turbo blanket same as the difference between having a wrapped exhaust system and reflective shielding on your intake. As far as a turbo blanket making a Turbo spool faster I'm not entirely convinced on that one. I think it might play a factor because less energy is being lost from the closed system in the form of dissipating heat, but it also means it is containing heat and that can cause many other things that could also rob power. For example metal parts expanding more, and tolerances changing. Not discounting your findings it is just my worthless 2 cents. I do think the pros definitely outweigh the cons
If you add a math channel that is DERIVATIVE(MAP) you get a channel that reads rate of change of MAP and read spool rate directly from the data.
I can make this easy. Yes they absolutely work. There have been many studies done.
I still like being able to show and prove stuff in simple experiments!
TLDR; Yes it does!
At 6.28 it looks like you put it on backwards???
I think also that those slots now on the downpipe side should be towards the center of the turbo.
I think that turbo blankets became very clever marketing spiel to milk consumers of their money.
To me it's never a "blanket", more a heat shield, and it's used to protect components near the turbo from heat soak. Not to keep the heat inside the turbo.
Which in a daily driven car would be catastrophic I might add because all that excess heat is only going to coke up the oil lines to the turbo.
Great idea, but the fact that these are different days and runs the data is skewed. You're forgetting the most important thing as far as performance.... environmental conditions.
That's very true. Fortunately, it was the same temp within 2 degrees as well as similar humidity etc. also why I tried to include as many other data points as possible. Though it wasn't perfect, I think the environmental factors were close enough to show some solid data and results!
3 data points is a trend.
