added a header to my CLONE.. saw ZERO GAIN

[1992suburban]

I bought the $30 Boxstock header with .880 3 stage ect ect ect


saw ZERO improvement in my opinion over my homemade and that was MARGINAL over stock muffler..

sounds LOUD but ok.. needs a muffler..

if I had it to do over I would buy the $20 one that uses the screw in briggs muffler .750 threaded one you know...


anyways.... I will have video and pics up soon

YOu guys know how I LOVE posting pictures and such

...saw ZERO improvement...

It's a matter of "Every little bit helps".

 

[1992suburban]

hahah maybe...

but for 30 bux.. I wouldnt do it again lol..

 

[Russ2251]

Agreed!!!

When I added the header to my stock clone besides sounding pretty mean, It seemed to increase bottom end torque.

 

[1992suburban]

well I had a Homemade header on there out of 3/4" conduit

so... ????

I actually saw a guy over on Bob's loose some power from intake/exhaust mods. Personally, thats the best thing I've done to my Subie. I hear that RLV mufflers actually get you some power power too.

 

[1992suburban]

I think a longer or smaller diameter would have been better

I hear ALOT these motors like back pressure

 

[modelengineer]

No motors like back pressure

 

[NJOHC]

It might not be a matter of back pressure, but many of these pipes are known to run better with the RLV. Whether it be because they are tuned to work with it or something else, they do.

 

[freakboy]

They like to breath... heres a test to see if YOU like back pressure... breath through a straw for half a hour... lol.

Im sure if the pipe is built right it will give more power increase.. one question is the pipe bigger then the exhaust port? if it is the exhaust might be loosing velocity.

No motors like back pressure

i strongly dissagree

 

[NJOHC]

2 strokes do, correct?

 

[1992suburban]

if you know anything about MOTORS then you know what I meant when I said "they like back pressure"

 

[Kenny_McCormic]

Jetting?

 

[newrider3]

2 strokes do, correct?

Try again. 2 strokes like the pressure wave created by a properly tuned pipe, to force unburnt fuel back into the chamber. Just backpressure by itself doesn't help, and isn't the same thing.

Kenny's got a good point, meyby you'll need to rejet to realise its full potental.

I'm not sure what all mods your engine has but I'd think Box Stock headers are designed for a completly stock engine besides air filter/rejetting.

As far as you noticing any improvement, I know kart racers that have tryed out serveral diferent model headers in hopes of just shaving a 10th of a second off their lap times... Without the stop watch, I doubt they'd notice any diference either.

Oh ok, thanks for the explenation.

 

[1992suburban]

its all stock with airfilter adapter cone filter and header tried .035 jet .036 jet motor runs good did a plug chop shes RIGHT jettin is real good

 

[Rickracer]

Could be you need a little port work to get the most out of that header. On my genuine Honda GX240, about 15 minutes with some tootsie rolls made a LOT of difference. I suspect a clone may be even more so.
