    I posted a little bit ago about getting some Exhuast heat wrap, and Justin recommended a Group buy.

    so i have talked to me friend about it and if there is enough interest we can make it happen. so i want to see who is interested.

    this is just a feeler so official pricing and stuff will be figured out at a later date.


    1.Dynapar 2 x (50'x2")
    2.LilRed 1 x (50'x2")
    3.BlackDubRX 1 x (50'x2")
    4.Justin 2 x (50'x2")
    5.LVT 1 x (50'x2") Longacre
    6.25RSMN 1 x (50'x2")
    7.Bikerboy 1 x (50'x2")
    8.jk78 1 x (50'x2")

    Yeah, you shouldn't buy it if you're just looking to spend money. Get a turbo or somethin. PS you already said what it does :roll:


    I'm interested, but I'll need a price before I commit.

    Why are people wrapping their exhaust pipes? Thermal wrap will contain heat in the pipes and not let it bleed to the air around the exhaust. I can understand it if you are trying to protect electronics, or if it runs next to fluid lines. But otherwise, won't you alter the readings from some sensors?

    Exhaust wrap in motorcycle racing was only done to protect boots and electronics, and sometimes you had to retune after it.

    Is there something I am missing?

    i am personally doing it to protect fluids.

    but when you wrap exhuast you keep the heat in (as you said) but doing this makes more exhuast volume (colder = smaller) so in a wrx/sti or other vehicle w/ turbo, this gives you more gasses through the turbo giving quicker spool up.

    atleast that makes sense to me.

    Also, it keeps the air from the outside heating up the compressor side of the turbo, intercooler, and charged intake pipes; which is heated up by the exhaust.

    Pardon my lack of knowledge on wrapping exhaust parts but is a 50' x 2" enough to do a dp? I have no idea how thick you have to wrap it.

    i think 50x2 is plenty to wrap a DP. from what i read you just warp it once w/ a 1/4" overlap on te spiral. BTW: arent ou getting that DP coated? are you gonna put a CO2 sprayer on it next? lol

    to improve the scavenging effect of the exhaust flow, you want hot exhaust

    Sorry, I got the PM from Dynapar. Life has been crazy lately and I haven't been keeping up enough. I will get ahold of Soren today and find out how soon we can get the wrap here.

    Soren and I are talking with another distribution place and we are trying to get an account with them. We might not move enough stuff to start up with them, but if it works out we can get this stuff a little cheeper. Sorry for the delay. The worse is that we stay with the prices that I gave you guys already.

    I know you are an N/A guy right now so scavenging would apply if you are using an equal length header. Are you?

    Scavenging basically is using the right length primary tube in your headers so the preasure wave of the burnt charge is timed to reflect back to the ehaust port when the intake and the exhaust valves are both open on overlap. This produces a suction effect in the chamber as the preasure wave bounces off the exhaust port and pulls the fresh charge into the chamber as well as "scavenging" any remaining exhaust gas that was not pushed out with that stroke.

    OK, now that I spit that out lets talk about subi's. First N/A subi's do not have tuned equal length headers. This is why we have the rumble. All the pulses hit the last junction in the primary (the secondary) really close together. Think of it as they are firing at 3-5-7-9 o'clock and the equal length headers they are all hitting the secondary at 3-6-9-12 o'clock. This is why people dont like loosing there rumble and "there car sounds like a honda" when they use equal lenghs. This is only effective with proper design (tuned length header)which I doubt anybody beside the factory or prodrive took the time to do the math for the subi guys. Wraping would help with tuned length header yes on an N/A.

    Now lets talk about turbo's. Scavenging plays no roll in the turbo system, we use boost for the same effect. Instead of using a bounced back wave from the tuned lengthed exhaust to create suction we get to blow. So at the same time in the cycle, overlap, when both the intake and the exhaust valves are open the preasure wave from the opening intake valve having XXpsi behind it does the same thing.

    So with my long rant here you ask why turbo guys use wrap and coatings? Most all will say heat, but that is not all of it. Yes turbos run much hotter that N/A so our exhaust is much hotter under the hood. But if you do everything you can to keep the heat in you do two things. You send it out the exhaust where it belongs and not under the hood. But, in the case of headers you keep the heat in so the gas travels faster. Remember a hot gas travels faster than cold gas. It is for better spool first and radient heat second in my mind.

    Ill take a 2x50 please!
