4AGE silvertop exhaust

[dencio1976]

as i was trying to take pics of an 8k or up rpm while the car was jacked and on 1st gear, i saw water drops coming out of the exhaust and on to the wall of the garage. is this normal?

the engine seems to run fine. just that.

yep, H2O created

[gixer]

yep, H2O created by also if you have cat

[dencio1976]

that's good to know. what's a cat by the way?

and exactly how does water get to my exhaust anyway?

Petrol is a hydrocarbon. Hydrocarbons, when mixed with oxygen (from air) in the right proportions and heated/compressed to the correct temperature/pressure, form carbon dioxide and water vapour. By the time the exhaust gases reach the end of the tail-pipe (especially if it is cold), some of that water vapour will have have condensed. This is how you get water dripping out of exhausts when the car and ambient temperatures are cool.

As an aside, if you take the carbon and oxygen out of petrol, you are left with hydrogen. Thus, you'll get no carbon dioxide in the exhaust, and you're left with just water. This is why hydrogen fueled cars are technically zero-emission

wow! does this mean ive got a good emission?

by cat, do you mean catalytic converter? i dont have one. i installed a twinpipe on my EE100/AE101 and had a 2 1/4 tube of around 18inches welded inplace of the catalytic converter.

Not exactly. Every car produces water as part of their exhaust gases, just you don't normally see it unless it is cold. And trust me, there is still plenty of carbon dioxide coming out of your exhaust too (which is bad, but unavoidable as all cars put it out too), and you can't see that.

[dencio1976]

well atleast that's good to know that it's normal. never seen this on other cars that's why.

while the car was jacked and on 1st gear

You've got to be careful when you do this, some cars use CV joints that lash about when they aren't in the laden position, you can make quite a nasty projectile out of a high speed CV. Just a word of caution.

yup i was very cautious of this. i was stepping on the clutch a little while i was doing this. thanks! also the reason why i did it on 1st gear only. i couldnt achieve an 8k+ rev cut if i did this on neutral that's why.

Its illegal not to have a catalytic converter you know?

And did you notice he's in a different country to us? Manila just happens to be the capital of the Philippines, which isn't Australia.

you werent gonna apprehend me or something, we're you? hehe!

yup, im from the philippines. unfortunately, catalytic converters arent mandatory on older model cars.
