wrapping my turbo, advantave or not?
 

i have a 91 non-ic cummins and was wondering if wrapping my turbo would have an advantage as far as boost goes or not? any input is great!!! thnak you

advantages for boost? i don't think so. it will help eliminate some of the heat under the hood due to the exhaust, but it will not increase boost any..... as far as i know

okay i figured that. i had a teacher tell me in college that it would help. i guess he was bullshitting me
:dang:

Where can I purchase the wrap for the turbo? My cousin was telling me today I need to do this. I'm interested in keeping some of the heat off my A/C box in my F350 swap. It is only a few inches away at most.

i agree with benjamin.the only thing you wrap them for is to protect things on the outside from burning up :humm:

geno's garage has it i'm pretty sure

Theoretically it'll help you make more boost; more heat will be utilized by the turbo instead of going under the hood. In practice, however, I would imagine that the largest benefit would be reduction of under-hood temperatures.

Heat is energy that cant be used to operate the turbo, so wraping it will be an improvment, enough to notice? Maybe maybe not.

well i would be interested in knowing if it makes a differece that a person can tell i dont think but i could be wrong wouldnt be the 1st time :w2:

Some swear by it.

I've just completed the installation of a new twin setup that includes ceramic coating of the exhaust manifold, hot pipe, as well as the exhaust housings interior with a heat rejecting material (keeps the heat from moving into the iron) and exterior with a heat retaining material (keeps the heat in). It works. :pca1:

As others have pointed out, it's the energy of heat that drives our turbo(s). The typical illustration is the fact that a pre-turbo EGT might be 1200*F. Under the same running conditions, but moving the temp probe to post-turbo now shows 900*F. That 300*F exhaust gas temperature drop represents the conversion of thermal energy to mechanical energy by the turbocharger. Anything we can do to keep the heat in the exhaust gases drives up the system's overall efficiency. :)

best example I've heard yet! Thats what I was thinking but didn't know how to say it!

thanks bobby and bc 847 always good to learn new things even if it means i was wrong twice so far in my life :w2:

I dont agree that heat drives the turbo. It needs drive pressure, the heat lost is most likely dissipated off the turbo housing and downpipe. The higher pressure the exhaust is will also make it hotter, and since the turbo is a bottleneck in the exhaust then it holds pressure behind it making it hotter. Thats just my 2 cents.

We're talking "heat" in a more theoretical physics sense... Think of "heat" as an energy that can be turned into temperature, pressure or mechanical motion depending on the properties of the system it's put into. ie. A big turbo can have a lot of heat go through it without actually having that much of a temperature or pressure drop. It's a flow thing.

i have my down pipe wraped with header wrap.... can't say i noticed anything as far as the turbp working better.... but i'm not melting the insolation off my heater box anymore

You would need it pre-turbo or on the turbo itself to notice any power difference. One the exhaust side the hot exhaust air has already done its duty and just needs to get out of the way. Now if you have a small exhaust slowing the flow of the exhaust then you will see even more heat pre-turbo and carried threw post turbo.
