Here's one to ponder....

[Seahorse51]

As an avid scuba instructor, I was in my garage checking my gear about 10 ft from my vette and it dawned on me......poor mans supercharger.

Why coundn't a person mount a small compressed air tank similarly to NOS but with enriched air, maybe 36% oxygen, with a hose that runs to the front of the TB and inject 140#'s of enriched air thru a switch that senses WOT and turns on the air?

This should generate some great conversation.

Oh yeah! :L

Well, as a devil's advocate, I wonder what benefit this would have over NO2. Would there be less hardware to install? More power? Easier to work with? Certainly O2 would be cheaper than NO2, I'd imagine.

Why not straight O2?

Hey KOPBET, PADI 166961

 

[Seahorse51]

rrubel, yes the equipment would be about the same but an 80 cu ft cylinder of regular air compressed to 3000 psi only costs about $4.00 and would certainly last much longer. Pure O2 would hold more hazards I would think. Computer probably freak out on pure O2.

Can we build an underwater enclosure for Corvettes? Then we would have the best of both worlds!

Hmmmmmm....now thats REALLY something to ponder.

KOPBET, I notice you are in tornado alley. Where exactly are you. I grew up in Wichita and now live in centrar Colorado.

Welcome reefdiver!

 

[reefdiver]

Thanks Seahorse51.......one thing struck me as funny here........you're from Colorado...KOPBET is from Tornado Alley.....and I'm from Pittsburgh. We all dive but live a long way from any oceans. Might be a good idea to have the CAC Cruisefest # 2 in South Florida. Corvettes AND Diving.......sounds good to me.

For what it is worth, nitrous oxide is N2O, not NO2.

Tulsa! Great diving around here, huh? :L

Yah, yah... details! It's been, um, 21 years since high school Chemistry class :L . Thanks for the correction.

That's weird that you brought that up! I was just thinking about this exact thing the other day at work when replacing one of our 02 bottles that we use with our medical gear! I am kind of interested to hear any war stories about people who have tried this........Come on, I know you're out there!!! :L

 

[DRTH VTR]

I have thought about this, too. I am no mechanic, so if this is wrong, I am interested in what is the truth.

The mass airflow sensor detects air, not oxygen. If part of the air (20% oxygen) was replaced by pure oxygen (say 40% end concentration), how is the computer to know to add more fuel? It seems to me that this would result in a very lean condition. No?

 

[Vettelt193]

what you would have to make is a sealed system... meaning, the air that you 'inject' into the engine couldn't have another way out (ie, you can't let it run out through the air filter.

what this would basically be is a supercharger (but bottle fed)... you can't really change the ratios of oxygen Vs. the rest of the air too much without doing other mods.

the reason why this hasn't really been done is the sealed system problem... look at a supercharger, the piping etc. from supercharger to engine is heavy duty stuff... and with only one way to get air into the engine. trying to figure out a way to bottle feed an engine compressed air, while maintaining the way the engine normally runs for 'regular driving' is near impossible.

 

[DRTH VTR]

How would the quantity of fuel be adjusted to compensate for the additional oxygen? I don't see how this could be ignored. If you ran on a constant oxygen adding system, the computer could be reprogrammed. But if you only used it some of the time, how is the computer to know which oxygen environment to use for fuel delivery?

 

[Vettelt193]

Ideally, you use straight compressed air. this keeps the ratio of oxygen to the rest of the air the same. The mass air sensor will compensate for the increase in air flow (assuming we aren't going nuts with the compression here). Realize that corvettes have engines that can probably withstand 8 PSI if tuned properly... for this setup, you would probably shoot for 2-4PSI. if you go above that, you are going to need heavier mods anyway, like bigger injectors (or extra injectors) and computer upgrades.
