I've got to go back to get my turbo blanket as I left it there... he took it off and told me it was a waste of time for my car hahaha.

You may be right Mick.. on both points.

Really? A waste of time? A waste of money, maybe, but can't see how it's a waste of time. He wasted his time by taking it off maybe.

Given it's a heat shield (or thermal trap depending on how you interpret what it does), even if it does next to nothing, that's no reason not to refit it.

Did he discuss with you before removing it (and not replacing it)? "A waste of time" would not be an acceptable response in my opinion.

Haha don't get your knickers in a knot
You'd have to meet MSR to understand. He's a no bullshit kind of guy, tell you how it is type of guy. Bare in mind he's a rally driver and does only what works or what he needs.

His reasoning was that it does absolutely nothing for spool time on small turbos, and the blanket will in fact trap moisture in there and can cause rust. There's also an issue with oil sitting in the turbo when the car stops and burning the oil.
He did agree that it helps keep that part of the engine bay cooler, but you do so at the risk of the other side effects.

I think youre taking it a little to literal. It was probably a joke form or a mini protest as a well experienced mechanic in defiance of possible gimmick products

I reckon it has to do with decreased back pressure.

Larger diameter and better flowing headers will remove a fair whack of back pressure

This will reduce the amount of resonance down low and thus noise

It seems to me also that Michael from msr has optimized your avcs to suit the headers, so now your engine note sounds different due to change in volumetric efficiency and thus noise levels too

Exactly. Better flowing headers allow for different avcs and michael is one of the few who really puts effort into his avcs.

Bruce's and mine both came away quieter after his cam timing.

No knicker knotting here. I was just curious about the explanation(s). But they haven't made me think any differently.
I appreciate that you'd rather believe the guy you're paying dollars to, but I see no risks in the so called "side effects" compared to what may be (admittedly) minor benefits.

I'd be interested to know how a blanket benefits larger turbos over smaller ones.
(I'm "thinking out loud" here, Adam - not expecting a direct response from you).
What aspect of trapped heat in a big turbo means they benefit but a small turbo does not?

Unless you regularly wash the inside of your engine bay with a high pressure hose I can't see how any moisture can accumulate under the blanket.
And the next drive you do will make it evaporate anyway.

The trapped oil idea is very interesting. Is this cooling oil, or oil passing through the intake and TMIC?
The blanket is on the exhaust side. What temperatures does it see (genuine question - I don't know the answer)?
What temperature does the "air" side see in comparison? And what temperature does the oil (whatever oil it is) see?

Anyway, I can't see any reason to take mine off. Besides, those heat shield bolts are a PITA to remove...

[peadya100]

In no way did I want this to become a preach about whether or not blankets are worthwhile... each to their own.
I trust my tuners opinion as it comes from 30+ years of real tarmac and rally racing experience... it's really hard not to listen to him when you're standing in his office surrounded by 75+ racing trophies.
Its really no skin off my nose to have it off. I can put it back on one day or sell it to someone who does want it.

[peadya100]

The other thing people might find interesting is the cold air intake install and sound.

As some of you may remember i put the process west cold air intake on my car once before... drove it around the block and took it straight off as i couldn't stand the sound it made!

As i was getting a tune for the new headers and TMIC, i decided to put the CAI back on and hoped id get used to the sound.

I installed the intake once again. For anyone that hasn't seen a PW CAI, the quality of their gear is as always exceptional. The fit of the heat shield is spot on! Once installed, i still really hated the sound, or not so much the sound, but the volume of it. To my surprise, the tune made the intake much much quieter!! You wouldn't even know it was on there now. The only time you hear it now is under load up a significant hill at low speed and its much less obnoxious... in fact i quite like the sound as its more of a turbo whine with just a bit of the sucking sound.

So long story short. If you ever wanted one and were scared off by the noise... dont be

[GONEWALKABOUT]

mmm juicy, how exposed is the intake to water in wet weather etc

[peadya100]

Ive heard people mention that, but it would take a lot to get it wet i think. The guard liner seems to be fully sealed so i guess for water to get in youd have to be driving backwards, as its in front of the front wheel, and there'd have to be a hole in your guard liner. I wouldnt call it impossible to get wet, but it would be very hard.

... until the women get near it.. heuheuheu.. sorry. Well thats reassuring!

Energy cannot be created or destroyed, only transferred. Less wasted energy making exhaust noise, becomes more crank energy thus more efficient combustion and less noise.

[peadya100]

I see. So I'm not going crazy, the exhaust can in fact be quieter.
But if I'm reading it correctly matt, you're saying it's a tune thing, not so much the headers?

[gen3v8]

What are you talking about? All the energy should be spent in the combustion chamber if what you are saying is so ie crank energy. What has that got to do with after the bang headers choice noise reduction

sort of but if you want to make what he said work, theres still the turbo post combustion
