Cold/Warm Air Intake

So they were in the same testing environment

Yeah i know sound does alot for performance for most young people haha. get your kid a loud muffler and an intake and they should get a bit less speeding tickets cause they THINK they're going fast haha

No, those things will make them get more tickets because they think they're able to go fast.

Trust me, I won more than my share of money from 17 year olds with mom's check book and no idea how to really tune a car. It's not even racing if you do what I used to do. It's slaughter.

The aspiration sound makes it go faster too.

It's commonly called an SRI, but unless you have a shield on the engine side and an opening for a source of fresh air, it's only just a WAI.

Either way, it's a common FAI... L.

How so? i thought warm air intakes were good for fuel economy?

Haha worked opposite for me when i had my straight pipes on my el camino i rarely drove ocer 50 or 60 cause that was the quiet point of the exhaust

Now that i have my stock muffler back on i rarely recognize it if i'm cruising at 70 or so

Gimme a break, man... the guy didn't install that filter for economy, he installed it because he thought it would get him somewhere in the HP department. Of course, real tuners and anyone that knows how engines work know that he's now starving his engine at higher RPMs, under heavy loading, because the air gets so hot it has the same mass as the colder air at lower RPMs.

The difference is that on his vehicle, there probably is no air mass measurement, it's based on a MAP sensor, which means he's getting stupid rich mixtures at high RPM/load curves, further polluting the country.

I seriously doubt if he's getting any better fuel economy, either. Butt-dyno, my friend. That's all it is. And that's a ricer mod, done by someone less concerned with fuel economy than Clinton was with the state of affairs outside his little circle (oval?)...

haha i would agree with you. and i do on all the info but i've riden with him lol and he can't afford to drive the car like that it actually was done for fuel economy because he's a broke college student

With the MAP it will compensate the extra airflow by adding fuel right? that's why it pollutes more?

[Christ]

MAP compensates for manifold pressure by adding fuel. It doesn't care about flow.

MAP systems assume a basic map of manifold pressure versus known VE under OE circumstances, and add fuel based on that. It will run pig-rich because he's stuffing hot air in the engine under high RPM situations, to the extent that the O2 can't recalibrate the mixture enough to compensate. If he does it long enough, the cat's toast. Raw fuel in a catalytic converter is a good way to have a car fire, by the way. I've had it happen.
