Loud Engine

[SilverSurfer]

how can you make your engine quieter. cause mine is super loud alot louder then some others so if theres anyway you can make it quieter without effecting performance that would be awesome.
thanks

Are you running an exhaust pipe on it? I only ask because, the engines run relatively quiet with them on and really really loud without. If you are, make certain that it is still properly attached and that the coupler (if there is one between pipe and header) is in place.

Other than that, you can try attaching an exhaust deflector to the stinger. It is a small tube that is used for redirecting the exhaust away from the vehicle. This will make it run a little quieter.

once you make your STINGER longer... means more torque and less rpm and same goes for longer MANIFOLD,

once you make your STINGER shorter......... smoother/less bottom end or torque and more top end power/rpm.

The steeper the angles on the pipe means power comes on harder but powerband becomes narrower.

that is the STINGER/MANIFOLD length affecting the performance yoru engine... cool eh?

k. so the coupler is the plastic thing which attaches the manifold to the exhaust?I will definately get a deflector but will this mean less power from my engine as the air travels further? or doesnt it matter?And if i get a deflector over the stinger and i put my shell on( i'm sort of freaked about puting my shell on ever since ive had my buggy the shell hasnt been on it because im scared it will melt)will the deflector protect the shell from the heat?

yup. sometimes we (over here at my place) called it GASKET.

if you are a BASHER and not into racing... i doesnt matter...

And if i get a deflector over the stinger and i put my shell on( i'm sort of freaked about puting my shell on ever since ive had my buggy the shell hasnt been on it because im scared it will melt)will the deflector protect the shell from the heat?

yup... it wont melt your body.
or you can make the hole on your body bigger than the stinger.... .

tune pipe shouldnt melt your body anyway, if it does it means your motors tuned to hot (bang) youll have more than your body to worry about, if your gaskets or o rings seals are f**ked you prorbably find you havent got much presure feeding your engine so you might be running lean as well, if all else fails buy a new tune pipe, we get the new efra style pipes with manifold, gastkets, and conection springs for about NZ$90 so in aussie oyou should get them cheaper

siic! thanks for that yeh i dont really wanna cut my shell but so i'll just use the deflector. and they're supposed to make it quietter but my friend has a swift and it makes it sound louder? why's that?

[mikeburgin]

deflectors dont muffle the sound at all and they do change the characteristics of the pipe regardless of what others think it changes the pretty little waves that resonate around in ther pie more lengh = more restriction deflectors were more designed for planes and helicopters

[SilverSurfer]

k so since i dont want to effect the performance of my buggy but dont want to melt my shelf what can i put over the stinger to stop it melting. im thinking putting the deflector on then just cutting it down? what do you think

[mikeburgin]

in all my years of racing i have never melted my shell, as longs as you give it enough clearance like a couple of mill it wont hurt it, what car have you got?

the worst killer of boddies is people that cut there design out of masking tape while its on the body scoring the inside, creates a weak point.

i have an OFNA Ultra LX Comp my first buggy

[mikeburgin]

i tend to just cut a tab out of the body instead of drilling a hole make removal much faster in race situations

SIngle chamber pipes are the loudest, like the stock pipe on a GS storm. They are deafening, louder than a chainsaw. I have to find quiet pipes because I have a track in my yard. I found the two chamber Dynamite pipe works well and is noticably quieter, plus I run a silicone deflector.

[dgrobe2112]

yeah.. ofna RTR pipes.. are single chamber pipes.. you need to get a tuned pipe.. you can go to ebay.. get the Jammin Pipe.. you will like that pipe.. and it will make your car quieter.. also.. the Jammin JP-1 pipe is a low to mid range pipe.. or the JP-2 is the mid to high end pipe

The stock tuned pipe on the Swift is loud to begin with. I have a deflector on mine and it certainly doesn't make it any louder, it also has no discernible effect on the torque profile.

The length of a side-exit stinger as used on RC car tuned pipes has very little effect on performance. The effect is more pronounced on large scale and RC boat pipes where the stinger is in-line with the rest of the pipe.
