What about turbo cool down time? Is the time you want to idle the car after hard driving extended? Or does it cool off at the same rate?

I have however watched the bare turbo with the infrared camera while it has been idling after some aggressive runs. There is "sweet spot" so to speak of time. I watched a bare turbo at 550F idle down to 400F in that couple of minutes. The normal operating temperature of the bare turbo at idle is around 350F, until driven then it wont dip much below 380F-400F at idle. Extended idle times can raise the temp back above 400F. |

with today turbos, the real reason to let them idle a few seconds is to make sure the turbine is not still spinning (or spinning fast)
spinning with no oil pressure is bad. i think this is correct... but others may have input. |

There is a misconception that the heat retained by the turbo blanket will cause damage to the turbocharger. This is not correct. Turbochargers are designed to handle well in excess of peak engine exhaust temperatures. Maintaining the heat of the exhaust within the turbocharger will not damage the turbocharger. However, as with all turbocharged vehicles, whether utilizing OEM or aftermarket turbochargers, it is very important to not shut off the engine directly after periods of heavy acceleration. It is advised by us, as well as all OEM and aftermarket turbocharger manufacturers, to allow a period of time to let the oil (and in some cases water) circulate and cool the turbocharger. We recommend that before shutting off the vehicle after periods of heavy acceleration, you should allow one to two minutes of idling to allow the turbocharger to cool down effectively. You may also consider purchasing a turbo timer to allow the engine to idle for a predetermined amount of time after you have left and locked your vehicle. |

I actually turn my car off in mid-WOT since my subzero ice water fed turbo can handle it. So what's the real truth these days? People get so obsessed with calling each other wrong that they neglect to provide the right answer. |

I agree with you wholeheartedly though. Seems as though everybody is obsessed with being right most don't want outside information. I'm in this thread for information myself. |

If I have found the that the detailed analysis, information and FLIR images the HeroCrank has assembled are informational and informative, is it wrong that I went ahead and supported him with a purchase? I think not.
I am enjoying my PTP Lava Turbo Blanket. |

Finally installed mine. I was able to wrap and place the OEM heat shield back on without issue.
Biggest problem was the ratcheting wrench I dropped, slid right to the middle of the engine bay out of sight. good thing I had another. Took me a quick drive and some time up on rhino ramps until I pulled down the cowling off the bottom and finally found it. Getting that thing out was a moment of joy. I found the only extra bolt I needed to take off was for the power steering bracket. Without pushing that out of the way I'd have never gotten to the two bottom bolts on the heat shield.

I've been seeing a lot of new faces around here with new cars the past few weeks. The thermal questions are starting up again and I encourage you all to research before you buy and ask as many questions as you can. Ill bump the infrared testing threads and please contact me if you have any questions.

Great bump to something I've been meaning to do but keep forgetting.
I just re-read this thread and thought of the TMIC. Essentially, everyone wants a turbo blanket to reduce underhood temperatures. But for me, the end state is to reduce the heatsoak and temperature of the TMIC, both at idle and after a few hard acceleration runs. Herocrank, do you have any of this data - temperature readings of the TMIC at idle and after a few runs with this new turbo blanket? That's key for me. You've clearly already shown how much this blanket reduces the temperature on top of the Grimmspeed heatshield but I feel the TMIC is where it is important. |

Really appreciate the support and I am glad you liked the thread. Enjoy your blanket this summer!

It's been awhile and I just got back to looking for a turbo blanket and remembered this thread. I meant do you have comparison temperatures of the TMIC - idle and runs - with & without this lava turbo blanket?

Bstflex Titanium Exhaust Wrap
The Titanium Exhaust Wrap - twill is constructed from fragmentized lava rock that is extruded into the fibers to create a heat wrap that will give you strength and performance you expect from an exhaust header wrap.
When properly installed, the proprietary weave in our heat wrap will allow an even dissipation of heat so that it will not over insulate your pipings or create any hot spots. Titanium Exhaust Wrap - twill promotes increased flow and keeps down underhood temperatures for improved performance and reduced vibration breakdown. Titanium Exhaust Wrap - twill is chemical and oil resistant that will not shrink or loose flexibility under extreme conditions. Titanium Exhaust Wrap is very easy to install and tightens down onto pipings without needing to be wet. Lava Heat Wrap Tolerance: Direct Contact Use Limit: 1800°F / 982°C Max Contact Use Limit: 2500°F / 1371°C |

BSTFLEX turbo blanket
The turbo blanket isolates the heat produced by your turbocharger, and prevents that heat from damaging, or even igniting, components surrounding the turbocharger within your engine compartment, such as plastic and rubber hoses and electrical wiring, as well as painted surfaces, such as the engine bay and the surface of the hood. Also, it prevents areas of localized high temperature from damaging the engine itself. In keeping the exhaust gases within the turbocharger hot, turbocharger efficiency is improved. As you may know, the hotter a gas is, the more expansive it is. Within a contained system of a specified size, the more expansive a gas is, the greater the pressure derived and thus, the greater the flow of gas to escape the containment. With this increased pressure and flow rate for a given engine RPM, the acceleration of the turbocharger's impeller is increased as compared to the same turbocharger with the engine at the same RPM but with cooler exhaust gases. This equates to faster spool up of the turbocharger, as well as greater attainable levels of boost. What a driver will experience with a turbo blanket is greater turbocharger responsiveness. The faster spool up of the turbocharger means less turbo lag and a more linear power curve. As you may know, it is very important to keep engine intake air cool. This is why intercoolers are often utilized with turbochargers. Similar to above, the cooler a gas is (such as intake air), the more dense it is. The more dense the intake air, the more oxygen it contains per unit volume. The more oxygen reaches the engine, the more power can be obtained. In keeping the heat of the exhaust gases contained within the hot side of the turbocharger and away from the cool side of the turbocharger and the intake path, more oxygen per unit volume reaches the engine, and thus, more power. |

Back from the dead.... yeah...
But does this blanket cover the center section or no? Too much coverage is bad. |

As a side note with the blanket off I lost ~150rpm of spool. 26psi by 3700rpm for multiple multiple runs. Put the blanket back on and 26psi comes on ~150rpm sooner. |
