Popping Exhaust

[Guest zoomzoom]

I think we have a new winner of The ''Having a stropp and throwing the toys award 2010?''

Would the winner please stand up, ooh he's left..............

 

Never mind we can hold the award in lieu of a return or am I being uneducated and unable to understand the science?

There is one science i do understand and thats beer making ! and theres one i don,t woman as for pintos i think my dyno guy knows that science... .

This has turned into an argument about who knows more theory than the other! And it's not needed really! As we all know the air/fuel system on each engine meters the petrol it uses in proportion to the amount of air that passed through the carb/ throttle body. This is why we use joints, sealants and gaskets to stop un metered quantities of air getting in and upsetting the mixture. So if your exhaust is forcing gasses in or out we are going out side the design of the closed system and thus reducing efficiency and performance. The simple answer is fix any leaks on the exhaust and if it still pops then look for the next potential cause. It could be 20 different reasons.

If its not needed Mcramsay, then why add to it by explaining how you think it works!

mine pops that much,ive nicknamed it The Weasel.

jess.

[Guest mcramsay]

im not adding to it by adding "how i think it works" im just saying it seems that people are getting into really deep technical arguments when theres no need. nothing i said in my last post was overly technical, nor did i quote equations and try to work out pressures within the exhaust system. if your car woudlnt start you wouldnt start fault finding by taking the head off straight away would you? so why get into a massive argument about wether an exhaust sucks in or blows out gas on over run? look at the easy options first if you think you have a leak in the exhaust system and you are getting popping then fix the air leak . if you still get popping then it must be another cause. Sure additional air going into or out the exahust is more than likely an additional contributing factor.

 

and Dinger even though im trying to take your response in the nicest way possible. theres no difference to "how i think it works" and how an engine actually works. or are you trying to tell me that carbs/throttle bodies do not meter fuel in proportion to the amount of air that goes through them? and that its ok to suck air in through a bad joint after the carb and get lean/rich burn in the cylinder? and then to blow gasses out a bad exhaust joint/ or suck extra air in.

 

all i tried to do in my last post was get some perspective back on the post, by explaining in laymans terms the basics of the fuel/air system. and if im talking rubbish please let me know.

[Guest dinger]

Calm down Mcramsey,

 

I was just pointing out that you said all this argueing was not needed and then followed with an explanation of how it works, Forgive me for pointing out the obvious.

 

I'm not trying to tell you anything, and dont remember saying anything to that fact, Hold on,

 

"Or can we just agree that the popping is unburnt fuel exploding in the exhaust exagerated by excess oqygen from a hole in the exhaust?"

 

This was meant be an end to a debate which was getting way out of hand, and to be honest, the origonal poster knows nothing more than the above due to everyone confusing him with too much technical jargon, and then a "who knows best" compitition.

 

Zoom Zoom took it in the manner it was meant, other may not have the same sense of humour, Appologies to those.

 

 

You say you wanted to put some perspective back in the post, but adding to the confusion wont help,

.....and that sums it up, time to grow up, if it pops so what??, build the dam thing, drive the dam thing and enjoy it ........

 

time we all moved on and share a drink across the BBQ at Stafford.

[Guest dinger]

I'm up for a beer at Stafford, all will be good when we are all together,

[Guest mcramsay]

I would love to " pop" open a beer with you all. apologies dinger I took what you said the wrong way.

[Guest scudoman]

In coming take cover,,,,, wait for it

 

So to put it in a "nut shell"......The popping is caused by air being sucked in through a hole or bad joint and doesn't do much harm to the engine........Thanks lads that all I wanted to know.

Ps. Thats a lot of posting for a simple question Ha...Ha......

Well said Mikae I really like that , lets all loosen up a bit and enjoy what we have mowerman

Always thought Baxter was the brains of your outfit.

 

Sorry but where is your science?

 

I use this simple equation.................. M + G X5 = 89IQ

 

B + G X5 = 101IQ

 

S + W X5 = 170IQ

 

Now the values are M = Me

 

B = Baxter

 

S = Spencer

 

G = Guinness

 

W = Water... (Spencer doesnt drink)

 

So we can see that the amount of guinness applied to each subject has an inverse effect on the IQ of each.

So infact Spencer is the brains of this outfit.
