Thread: Removing heat shield - turbo

Depends for how long and how you drive it while it's off, it might cook the windscreen washer tubing and the foam on the bonnet...as about leaving it off IMO it's not a gain cos the turbo likes heat, i have a titanium cover fitted to mine and it seems to me that it runs better with it....

I have seen a few posts where people recommend removing the heat shielding altogether

for those who are recommending that^^^ i recommend to read this Turbocharger Heat Shielding - Fact Or Fiction - Import Tuner Magazine ... and as i said i feel improvement on my own after i fitted one

I was just going to drive it to work for the week and see if I'm still getting a leak on number 5. Just 30 min drive in light traffic (I go against peak traffic flows). I cleaned up the soot so will see if it is still blowing.

Interesting article thanks.

where did you get your Ti heat shielding from?

Yep and some that send to Oz or are in Oz at varied prices

T3 Titanium Turbo Blanket | eBay

thanks for that.

Did you use any exhaust wrap? I see some sell it with the cover. I have a roll of it on the shelf. Was left over from a project at work. I had used a bit of it to insulate a coffee machine boiler. Not sure what to warp though. Is it just the top of the down pipe?

I think you are getting the LR heat shield mixed up with a turbo blanket. The heat shield does not shield the surrounding objects from heat from the turbo. At the least, it stops people touching the hot bits. At best, it directs air over the turbo, to dissipate the heat. The turbo blanket looks interesting, but all the data given is based on high performance petrol engines, where there is more heat generated than on a diesel. I would like to try one though.

I have had the LR heat shield, engine acoustic cover, and under bonnet cover removed for about 2 years. The last two because they just either got saturated with oil, or fell off. [ before I took off the heat shield] Now I can spot any oil leaks or exhaust leaks early. I have driven perhaps 20,000 km's with no noticeable adverse effects. I don't advise any one else to do this, but it works for me. I'm not interested in arguing the point.

remove the acoustic covers by all means I highly reccomend this.

DO NOT remove the turbo heat shield.

its the perfect shape and size for reheating

party pies
sausage rolls
garlic breads
pasties.
wraps and kebabs.

I'm not interested arguing either, i just want to respond that i didnt mix the factory fitted heat shield with a blanket just read few posts where members recommended to remove it especially "to let the turbo cool better", or as you said

..... The heat shield does not shield the surrounding objects from heat from the turbo. At the least, it stops people touching the hot bits. At best, it directs air over the turbo, to dissipate the heat.

and my recommendation was to show that removing the shield has no benefit at all and dissipating the heat means cooling it a bit too for me
As about it's real purpose who knows... that's what RAVE sais:

at the turbocharger....

I declare that I felt an improvement in throttle response after the blanket was fitted and the cooling seems to be more efficient with it(i hope it's not a placebo effect)... and i'm not alone(even though the involved diesel engine is huge(which means it doesnt get so hot) Installed a turbo blanket, interesting results! - Diesel Place : Chevrolet and GMC Diesel Truck Forums

Mine came without it so no but i'm thinking of buying some, IMO it should be applied along the downpipe untill it leaves the engine bay
