what's the difference between torque pipe and tuned pipe? :-)

a torque pipe is a tuned pipe...a torque pipe is long, then you have a mid range pipe wich is a bit shorter then a high speed pipe which is shorter yet..I belive most hsp aluim tuned pipes are of the mid-range or torque variety

No you have it mixed up, a torque pipe is short and fat, and a rpm pipe is long and skinny.

i agree with torque = short

but it does not end there, obviously.

i have a Losi Aftershock that came with a long fat pipe. they call it a tuned-pipe.
But man does that pipe sucked. no bottom, no top, no middle. The pipe was just killing the engine.

Then i swaped it out for a HPI polished pipe, which is about the same lenght, about the same diameter, but has a real tuned pipe shape.

Man what a differance. The Aftershock now runs like theres no tomorrow. Huge bottom, huge middle, and very good top. Its bassicaly not the same truck anymore.

So, my point, for newbies of course, dont take for granted that a short pipe will give you bottom end and that a long one will give you top end. Ask the guys arround before you buy. The internal construction is the major point there and usually, what you see of a pipe (the exterior) is just the exterior, nothing to do with the performance.

My 2 cents.

no I do not have it wrong...

do your homework...

iam upgrading my volcano sv which one is better?

team associated torque-tuned pipe or the hpi aluminum tuned pipe 21+polished?

firebird, you are right. wikipedia says the same thing.
there is a differance though, i think, if you play with the header.... which will provide more bottom if its shorter... i red that somewhere on the net.
but anyway, you are right bro.


RichardTF, i own the HPI polished +21 and it rocks on my M26SS (TeamLosi Aftershock) i love it.
As for the Associated tuned pipe, i dont know how it performs.

But then again, the HPI works well on my M26SS.... does not mean it will work well on your mill...

I heard the Losi Hi-Torque is an awesome pipe on most engine... you might want to try it out. Thats the one i wanted but i ended up getting a good deal on the HPI... and i dont regret it.

but you have a Volcano SV? the hpi might be too big for the small mill .18 you have in there... (will not even fit on your frame!)
I suggest you grab a 1/10 tuned instead... the HPI and LOSI HT are all 1/8 (way too big for a volcano i think)
any opinions?

The shape of the pipe doesn't matter one way or the other. 2 cycle are designed to run better with a certain ammount of back presure to the engine. The pipe short, long, fat or tall is there to restrict volume. How you restrict the volume is how it effects the reformance of the engine. There are a lot of pipes out there that lay claims to one thing or another that do nothing but restrict air volume and they call it tuned [sm=confused.gif] tuned to a 350 yamaha [sm=lol.gif] word of mouth or experiment yourself is the only way to know for sure if a pipe will work for you [:-]

Alright maybe i have it mixed, up, but no need to be such an *** about it bro. Im confused on why ae has their torque pipe fat, and the rpm pipe skinny then. And why boats have long and skinny pipes when they run at full throttle almost constantly.

wasnt being a ***** man.... just saying if your not for sure someone is right look it up before ya post is all...heck thats what these forums is all about is helping each other..as far as why some pipes are skinny or fat I think it would be how its chambered...some pipes are just a aluim tube and nothing more...John is right on experience and listening to others on what pipes work or dont work well...anyways the length of the pipe is SUPPOSED to have a different effects on performance..
I have heard good things about the ae pipes with a vx or sh engines...but thats just what I hear

Alright, its been a while since i read about pipes so i guess i forgot, but i used to have the ae "rpm" pipe and so thats what i was thinking. But after i read and thought about it i noticed i was wrong.

I myself love my team ae torque pipe. I also have it on my volcano, i think it's funner to have that extra little kick on the low end that will get u around off road a little better. But if your a stree driver, or just want as much high end speed as you can get go with an rpm pipe, i'm assuming that the hpi aluminum tuned pipe is and rpm pipe, but u know what assuming does.

Ya i used to love speed runs, but i sold that and got me a redcat pipe, great pipe

has anyone tried the traxxas resonator pipe?
