uh, don't. :P (I need a 951, not him)

Remember, you put the nozle in the intale pipe, not in the cam housing!

Well, he says he is 25, so lets not get carried away with age here. We all know that just being young doesn't neccessarily denote stupidity. (Well not allways atleast!)

since we are on the topic of nitrious i heard that water injection does the same thing. Anyone know $$ and what kind of performance you get out of it and where it can be bought

Come on guys, give the dude a break. You know most of us have Nitros bottles in our car! How else would we tear up the track? German Engineering? Come one! Here is the secret!

Blue, if you didn't post it, someone else wouldve!

lol... how did i know that was coming before too long?? ...water injection is far different from nitrous. The only similarity is their effect at cooling combustion temps... but that is water's sole purpose, where nitrous' main purpose is to add oxygen content WHILE cooling the temps.

FSAE - it also increases compression by adding more mass per volume... i'm too tired to entirely explain it... jets use water injection sometimes for more power.

Yeah, once i saw that pic it blew my mind! I must have laughed all night. I am always ready to pass on the humor!

It's not that complicated, is it? It's just more dense than water, so there's more matter in the chamber, right?

FSAEracer03

Mike,

i understand that, but thats a pretty negligable increase if you're only adding a small amount of H2O... think of how many cc's a chamber holds at TDC relative to how much water would be sprayed in to create non-compressible space... is it enough to really produce useful torque?? Now you've got me thinking and curious, but I'm dead tired too, so we'll talk about it tomorrow.

...wait a sec... the water is compressed and heated to vapor... vapor CAN be compressed... ok, you definitely need to explain this tomorrow, lol (I promise I'll read it after i drink my coffee so I'll pay more attention, haha)

Water vapor is still more dense than air probably. That's my guess anyway.

ERAU-944

actually in meteorology class i'm fairly sure i was told water vapor is lighter than air. so maybe it does just cool. it might help though adding it far enough back to help the VE of the engine, but you'd still have to account for that via the AFM somehow, so you'd be getting the effects of a vacuum leak... so it stands to reason. in jets, they inject it so that its added to the volume of air, and yes, it vaporizes (otherwise you'd get a nasty flameout) and thats how it increases thrust(via increase in flow volume, but even then you get the disadvantage of that 8#/gal of having that water on board). i think the physics of the two type engines are different enough that it might rule water injection out as a possibility for a horsepower increase in our case.

more tomorrow, its 2:16! i'm going to bed!

hey epic2112, i just turned 17 myself....does that mean i'm immature and stupid too?
