To Heat Wrap Or Not To Heat Wrap

[2brag]

Is it worthwhile heatwrapping my TXS down pipe?

I have seen information about the temps that can be produced and so on, but more so the hotter the temp inside the pipe the better the flow which is ideal for a turbo car.

So is it worth it just a waste of time and effort?

Thanks in advance

from what i know it is a waste of time especially since raising temps in the exhaust is gonna change readings for your oxygen sensor, which could fool the computer into dumping fuel to cool the exhaust lowering horsepower.

I have a buddy, 30, who has an MA in engineering. He buys EVOs, takes the whole engine bay apart, rebuilds them from the ground up over the course of months, and then sells them for sick sick prices. He helped me put an electrical boost gauge in this past weekend and I asked him, "Should I wrap anything in that heat wrap stuff? I see tuner mags and stuff and people wrap everything with the heat wrap." He said, "Nope, waste of money for the little it does."

So, yeah, I am leaning toward believing the expert.

(uhm) You always see strip cars with everything wrapped, so maybe its more like buying lightweight lugnuts, it does something but does it really make a difference? I have recently bought heat wrap, stainless steel zipties, and silicone spray because I was going to heat wrap the 2 sections on my fmic piping where its right next to the radiator hose, my intake gets really hot and its not even as close. Thing is after my motor mount broke I havent done anything to my car, so (wiggle) not sure how much that would help. Im pretty interested aswell to hear what people have to say. Its a big pain in the a$$ to do a Dp though...


Ps I didnt realize you have lightweight lugnuts, do they feel any different?

Wraps increase exhaust scavaging on long tube headers... no need to use it on these cars, let alone anything that isnt making 800+ hp with open exhaust and big headers.

heat wrap also does a wonderful job of trapping moisture and aiding with rust and corrosion. I had a very nice set of stainless headers on my Buell S1 that rotted out in what seemed like a year.

I did mine... Don't know if it makes a difference but... It's also ceramic coated so it helps with avoiding rust.

I like the blankets more then the wrap.

holy crap....def a small turbo.....*Cough Cough*

 

[northmiler89]

yea... i think i am going to have my dp and rp ceramic coated

 

[AutoXRacer]

It you ceramic coat something, you don't need to wrap it...
Ceramic coating is an alternative to wrapping...

Only wrap if you need to protect adjacent components... Wrapping will oxidate parts!!

 

[xenon929]

Trust me, I had to do both to keep heat down. And if you have ceramic wrapping will not oxidate parts anywhere close to what it does alone. Essentially, by the time that happens I will have sold the car. ;-)

do it CHICKEN

A Master of Arts in Engineering? I sure hope you meant Master of Science (MS) in Engineering. If he has an MA in engineering, I don't know that I would trust anything that comes out of his "Cracker Jack diploma " mouth.

Like said above Heat wrapping is to keep other stuff in the engine bay from getting too hot like having a giant turbo under the hood that likes to actually glow red hot melting every electrical connection and your hood. Oh it also helps with shooting flames out the tail pipe...

haha

That is funny. I have a BS and MS in Mech and Nuc Engineering...never heard of the MA...."Much Appreciation" for your attendance in my engineering classes!!!

Ok seriously have already done this mod for my txs downpipe and charging piping. with out a heat shield and the down pipe i recorded a temp of 225 F at the down pipe and at my cobb sri i recorded temps of 180F. After i heat wraped my fmic piping and the down pipe i recorded a temp of 185F at the downpipe and 155F at the sri This was down after driving the car while warm, on a 3 miles loop and letting idle for 30 secs. I also recorded the temps with the hood closed for 5 mins at idle. The outside temp was 75 F out side!!!

MA Engineers...
Yea they all go work for the movie industry:
Sound Engineers, Scafolding Engineers, Starbucks engineers, Lighting Engineers, ... they think if someone works with technology it makes them an engineer....forget the fact most of us who actually got a real degree worked our asses off for it... only ones IMHO that should be able to call themselves engineers are those with a degree and those who drive trains... the rest sorry are nothing but posers... (yes I feel strongly about this.. you think Doctors or Lawyers wouldnt mind if you started calling yourself a Doctor because you took a CPR class or know how to use an ultrasound machine)- Dont take me wrong - I have a lot of respect for technicians and some know more than some engineers but a guy working on the set of a movie hooking up the sound is not an engineer but a Sound Technician...

Sorry... thats just a sore point with me..back on topic: I have to side with those who say the heat wrapping is to keep the heat from other components in the engine bay and NOT to keep the exhaust gases hotter... I see benefit from keeping heat away from engine bay (wiring, intercooler, intake) but none from trying to heat up the exhaust gases....about the only one that benefits from hotter exhaust (and thats to a point) is the catalytic converter
