PRL big turbo: Turbo Blanket vs heat shield

[teders]

Hey everyone. Trying to figure out if i should use a turbo blanket option for the Garret turbo, or keep the heat shield that PRL provides with the kit. I dont think the heat shield will fit if the turbo blanket is installed, and so i'm wondering if anyone has done this already or has an opinion on the matter.

Thanks

I used a PTP blanket after I broke one of the heat shield bolts. Fitment was great and it looked better in my opinion. Performance seemed fine but I did not do any in depth testing.

Notice any difference in your IAT or coolant temps?

I left the heat shield off when I installed the kit. Looks much better in my opinion. A turbo blanket will work good.

I wrapped my downpipe and front pipe too since those get pretty hot as well. On a nice day I can keep my IAT2 5-10 within ambient for a good while before too much heat builds up in the bay.

I did not, but I again stress that I did not make an effort to do any thorough testing.

A turbo blanket (and heat wrap) is insulation, a heat shield is merely to prevent heat soak into other parts. The blanket should do way more as it contains the heat within the turbo... to escape from the downpipe. If you want the best results you should wrap the downpipe, you can also add gold tape to the intake bits to prevent heat soak.

I haven't seen anyone able to put their heat shield back on the turbo after the blanket anyway.

What would be a good compatible turbo blanket to use

Well the one I got is the T25 compatible turbo blanket from PTP.

Which one did you use? I have the generic T25 one and fitment was a pain with the EWG setup so we opted to not use it.

I don't have the part number handy but it was a PTP turbo blanket. I did not have the EWG installed with it.

The heat blanket will insulate the turbo heat and lead to greater thermal efficiency. You may notice a slightly quicker spool and slight power gains. The turbo blanket will also drastically help with heatsoak by reducing engine bay temperatures.

The issue is that the heat is being contained within the exhaust housing, which is right next to the CHRA, which is fed oil for cooling and lubrication as well as water for cooling. By running a turbo blanket, you're asking the oil and water to take on greater loads, which can result in the engine overheating (overheating and heatsoak are two different things).

The conductive heat of the extra hot exhaust housing is greater than the radiant heat it would give off without a blanket.

An alternative would be to run a vented hood or hood vents to evacuate the radiant heat that a blanket-less turbo would give off.

@ApexEight great points, i also installed a high flow grill at the same time i did the turbo blanket. really helps improve the efficiency of my radiator. About to post to my build thread, check it out.

Here's something that Russel from @ACUITY said to me a while ago :

"Remember that the turbo dumps heat into air after it passes through the rad, so it is not impacting cooling. Also keep in mind that putting a turbo blanket on a turbo means the heat can't escape that way anymore, so most of it remains in the exhaust and heats up exhaust pipes elsewhere and the balance of the heat absorbs back into the motor and subsequently into the cooling water (which then goes to the radiator). If anything, the turbo is a flow impedance since it sits right behind the rad."

"I think a good compromise would be a heat shield on the turbo, blocking anything like intake piping where radiant heat is problematic. Although I am not sure if any company is making a decent option. Similarly, you can wrap the objects being radiated to (the parts absorbing heat) with insulated, reflective tape rather than opting for the blanket. "

Insulating the turbo always seemed like a bad idea to me. I would rather insulate the intake.

Not sure if it’s even a viable option to get done but is ceramic coating any better? Rv6 is supposed to have that as an option on their new turbo
