These tests have been done many, many times before but I still found this video very interesting to watch. They also reference some testing done by UT Austin on a Cummins Diesel engine, but all around the blanket results were promising. Also very note worthy is the UT study measured the temperature of the oil feed AND the oil drain, and found that the temperatures were actually the same as it passed through the CHRA, meaning any worries of blankets "coaking oil" is unfounded.

I'll let the rest of the video speak for itself, but the tl;dr version is that these blankets do exactly what they're advertised to do.

 

It would be nice to see some controlled data test between different turbo blanket manufactors. And lava, titanium, etc....

 

Nice find!, pretty much re-enforces what people on HT have been saying for years faster spool and lower underhood temps

Pretty sure when I bought my PTP blanket in only came in "lava" anyway and its much better quality then DEI IMO

 

The DEI lava blankets I've seen appear to be a little thicker than the PTP blankets, but their price tags are a fair bit higher than the PTP and I've had more problems with the DEI blankets starting to fray on the stitching or come apart if they happen to snag into any other clamps or things like that.

 

FUUUCCCCKKKK. I bought a new DEI blanket back in november. And i find out their quality is iffy. They do seem thicker though. PTP does offer the titanium variant now. But i decide now to go back them after how my old one turned out.

PTP blanket after seven or so years

^Just make sure you don't do something stupid like get it stuck under a vband clamp like I did. The way the DEI are stitched seems to be a bit less forgiving towards things like that.

 

yup I had a DEI, fell apart when I had to remove it...@LSjoker youl be fine just dont touch it once its been heat cycled lol.

When I removed my PTP I did not have any issues with it coming apart seemed pretty solid

 

I've had a PTP for years and it only started to degrade when I lost a wastegate bolt and the exhaust gases were shooting out on top of it, eating away at the outer 'case', exposing the insulation.

Otherwise Mint

 

I want to wrap Charles' beard around my hot side and observe the insulating ability.

 

My ceramic coated Tial V-band housing doesnt get nearly as hot as the old cast iron piece I had. Even after a 25 psi pull.

 

I'm planning on using the Tial stainless steel vband housing, coated, with a PTP blanket on my build. Should minimize the hell out of heat radiation.

I also like that the SS/Vband housings don't weigh as much as the larger cast iron housings, I think that will help somewhat with nut/bolt issues on the studs. Could even help prevent cracking somewhat since there's less weight hanging off the manifold.

 

I'm in the market for a turbo blanket and it looks like PTP with lava is the overall better buy (and the one I'm leaning towards). Anyone have any experience with the ones from GoAuto?

 

The blanket is a must have in conjunction with other tricks, the wraps themselves fall apart overtime but there is a trick to extend the life.

 

...and the trick is...?

 

I put a new Thermal Zero one on last year and with a few thousand miles on it it seems to be doing good still. No idea if they are good quality blankets or not though, functionally.

 

I thought about putting a turbo blanket on mine....but the turbo is in the front (D,B, H series for example) unlike the back area like most VWs. I guess it is beneficial for those with turbo K-swapped cars. Other than that...I doubt it really helps much.

 

helps regardless of location, really. I've had turbos fitted in both locations off a vehicle. It ALL helps

 

Will still help significantly with reducing under hood temperatures, which is always a good thing. Less heat soak is always a benefit. Could also lower IAT's depending on how the intake is routed, and as per the topic/study provides a small bump in spool time.

For people who use a top mount style as well it can help keep the paint on the hood from fading, which will happen rather quickly if the car is driven often with an exposed exhaust housing only an inch or two away from the hood.

(I will agree though that on a K-Swapped car, a blanket goes from being a "good idea" to 100% necessary).

 

Yup. I turned a section of the underside of my freshly painted hood from white to a cream color in a matter of weeks without a blanket. Adding a blanket stopped that from progressing and helped keep the engine bay temps down. The blankets help protect surrounding plastics, wiring and connectors from becoming brittle over time from continued heat exposure as well. I usually recommend them on most builds. A blanket combined with at least the downpipe wrapped will make a huge difference in underhood temps. Most people don't opt to wrap their shiny manifold for the bling factor but that helps a ton too.
