I feel like if you have the stock air box, or EC V4 intake there would be no benefit to the blanket. I kind of understand how engine bay heat could effect your intercooler, but where is the 124 intercooler?I saw that Madness Autoworks is offering up a turbo blanket for the 124...what do you guys think about the use of one???...they have been around forever...I have never used one...looking for opinions...
Yes, you do. The turbocharger uses waste heat in the exhaust to spin the turbine. Keeping that heat in makes your turbo more efficient.The turbo is hot,right? And giving off heat to the engine bay is understood. But would I want to keep the turbo hot as opposed to cooler,w/o the blanket?
Thanks. My,how much has time changed turbos. My last experience decades ago with a 924 turbo was an eye opener with coking oil. Just prior to shutting down,it was best to let it idle for 30 secs to avoid just that. The NACA intake on the hood was too hot to touch.Yes, you do. The turbocharger uses waste heat in the exhaust to spin the turbine. Keeping that heat in makes your turbo more efficient.
Here's a Master's thesis a guy did at the University of Texas last summer. He concludes thermal blankets make a significant (but not huge) difference in turbo output and spool-up time.
He also found that even though the outer walls of the turbo were hotter, there was no change in the oil temperature at the bearings so there is no danger of coking your oil from the extra heat.
His conclusion seems to be that a blanket offers measurable benefits without any significant drawbacks.
