wouldn't waste my money on a K&N filter either

I had a V8 swapped S10 ( ~330 horse) running mid/low 13's in the 1/4.
Bunch of people told me I needed a bigger K&N filter vs the itty bitty fram ca353 I had on it. So I ran it with a vac gauge hooked up, several passes with and without the air filter. Always read 0 - 0.5" on the vac (at WOT) and et/mph were unaffected. If no filter had no effect then neither would a $$$ K&N.

Maybe it would help if you have a large cube motor and/or forced induction turning a lot of rpm.

Short ram or Cold air dosent matter the performance difference is minimal. I've seen flow bench results first hand with top manufactoring systems. On a consistant basis thier is only a 2% to 3% difference in air flow and you can get the same 2% to 3% by just switching to a performance gauze or steel mesh filter. Cold air or short ram aftermarket is a waste of money. I mention a K&N because they are still the world leader in performance filter aftermarket.

The only reason fuel is required is for use as an ignition agent. Our atmosphere does not contain enough oxygen to create the explosion required in the combustion chamber. The fuel is used to offset this balance and allow the oxygen to ignite and release stored energy.


Questions so far?

You have that part backwards. Oxygen is not flammable by itself - but combustion is impossible without it present in some form. It is just an oxidizer like nitrous oxide is.
You need oxygen, fuel, and a source of ignition for combustion to occur (preferably oxygen and fuel in the correct proportions).
Doesn't make your statement wrong, just a detail.

Do you ever run density altitude or oxygen altitude calculations at the track?
Factors to consider are temp (cold air=dense air), humidity(water displaces oxygen), and barometric pressure(effectively the weight of the atmosphere - relates to density).

ya - exothermic simply means the reaction produces/releases heat. Been thru a few engineering physics courses.
Would have to add that (atmospheric) oxygen isn't exactly a constant. That's why you see drag racers and pilots (among others) adjusting their tune to compensate for density altitude. It's also why your car will slow down on those hot humid summer days.
Smokey would have known this, but he was a little ahead of his time

Gotta love the top fuelers, 16+ hp per cubic inch with all the durability of wet tissue paper. Not so sure nitromethane has an octane rating but it does have some interesting properties.

WRONG! Oxygen is NOT flammable but can make one hell of a fire given a fuel and ignition source. I.E. oxygen is an accelerant.

No single ignition source of the fire was conclusively identified.

The Command Module Environmental Control System design provides a pure oxygen atmosphere.

The fire in Command Module 012 was subsequently simulated closely by a test fire in a full-scale mock-up.

The test was conducted with a 16.7 pounds per square inch absolute, 100-percent oxygen atmosphere.

The test conditions were extremely hazardous.

The rapid spread of fire caused an increase in pressure and temperature which resulted in rupture of the Command Module and creation of a toxic atmosphere.

Studies of the use of a diluent gas be continued with particular reference to assessing the problems of gas detection and control and the risk of additional operations that would be required in the use of a two-gas atmosphere.

However, in lay terms, more air in, more air out, reduction of resistance equates to more power and efficiency.

Done.

Some materials react explosively if they come into contact with pure oxygen at high pressure. Other materials may catch fire spontaneously. Such materials are incompatible with oxygen.

Besides, there is a thing called dusting. This is where an engine basically gets the internals sand blasted. From so-called aftermarket air filters that let in more dirt, along with more air.
