Hey guys well i decided i was gonna take my kit apart and wrap everything in heat wrap, but when i went to go buy it the guys there said something about after time the piping becomes weak when using heat wrap, is this true?

also what are the benfits of venting the wastegate to atmosphere on the turbonetics kit? cause ive heard of gains on the greddy kit, but will i see the same gains?

 

If it was a mild steel header I might be worries. But SS 304 piping isnt going to have any problems with that. As for dumping the wastegate on the out of box kit, no gains. Turbonetics tried it on my car. ZERO increase in HP, ZERO increase in response or stability. The only thing that changed was how loud the car was.

 

what about the downpipe and turbonetics exhaust piping?

 

Thats what I meant by SS 304 steel. Thats what Turbonetics piping is made of. The stock headers are made of SS409

 

where do you get heat wrap from?

 

^^^^ your local race shop should carry it in 50' foot rolls.

 

www.jegs.com has it to. $38 for a 2"x50' roll I think. The Snap Straps Thermotec sells make it easier too. They are $17 from Jegs..

 

I wrapped all my pipes from the TN kit before the install. I purchased 2 50ft rolls from Summit racing. It took some time and that stuff is kind of itchy if you get it on your self. Good Luck.

 

My piping is heat wrapped with the Thermotec carbon header wrap. I couldn't tell any difference performance wise, but the heat in the engine bay was decreased greatly.

 

Oh, and between the header wrapped piping, high temp coated manifolds, isothermal plenum spacer, and vented hood, my engine bay ambient temps actually feel cooler than stock.

 

heat wrap does weakin it is 100percent true since the days of old school racing when your parents did it. Instead of heat evap, it is kept in the material constently with saturation and over time will most definetly weaken it even if it is 304 Run a vented hood if your worried. But dont listen to me im no metal expert. I just go by what ive seen and heard over the years of playing in this game

 

It will weaken the metal but I have yet to see a SS304 PIPE crack. I've seen headers themselves crack from weight but if you wrap a properly supported SS304 pipe I don't think theres any issues.

 

what about getting it thermal coated rather than heat wrapping it? Sure its more money, but would it be any less prone to fatigue?

 

I imagine it would be the same or close to it. Personally I'm going to do both. Jethot my piping AND heat wrap it.

 

i agree with miaplaya, i have only heard you need to be worried on thin steel headers. but on the flip side, if those wives tales were on race cars not driven much and held moisture under the wrap for lengths of time it would help rust the thin steel, and that could be the prob people were getting too. who knows. i run it on my Z, my vettes, and my quad, lol. not a burn through yet!

 

could be true who really know that metal area is not my expertice. ive ran it on my Supra TT no issues but then again ive seen it on SE-R turbo cars crack the Fmax manifold

 

Keep in mind that the Supra TT has a bit more support for the maniold. The SR20 manifolds I've seen dont have a lot of bracing.

 

Just got off the phone with my manifold guy he did say that SS304 is stronger then mild steal but one must not exclude it prone to weakening due to heat wrap. all metels that endure heat and keep that heat in will be prone to weaken or crack. its a god given with metals of this nature. now the SS304 is made to exhaust the heat off alot faster then regular mild steel and make itself cold to touch in minutes vs mild steel. Either way I know there are different circumstances in ways turbos are mounted or braced and such but let me stress this area is not my forte so dont take my word for it.

 

well looking at the worst case scenario of each case. either potentually crack a manifold, or possibly get temps so hot you melt wire harnesses and fuse wires together causing engine fires (yes it happened to me in my vette, burning through a braided fuel line and nitrous line, yes it was bad!!!). header wrap is here to stay, hahhaha.

 

soo true
