The carbon trap removal is worth 2rwhp. It was dyno'd

elvism

i'll second that

I've heard 2 somewhere else too. But I also have heard as many as 8 and that was proven with a dyno as well. It really depends on the car, temperature, situation, machine, etc. Removing the HC trap will average around 5 HP. That's a good average.

Any adverse affects of removing the carbon trap? Need a tune?

HOTLAP

Wow - I'd seen posts here that removal (w/o a tune) actually hurt hp and one person claimed to have dynod & lost 3 hp......

Fordracing200

nope, stock car minus the cabron trap dyno'd plus 2rwhp.

Um...YES, you trying to tell the guy he imagined his "Real World" experience? We've seen everything from negative numbers to +8.

I don't like to get caught up in numbers, real world experience tells me different. I removed my H-Trap with a K&N filter change. I lost 2 mpg, and the car didn't run right. Put the trap back in and I gained 4mpg, and the cars acceleration was back to normal if not improved.

That might not be everyone's experience. Don't forget there are a lot of variables here. Add up the +'s and the -'s and you end up with a result that's statistically insignificant.

Face it, the car needs a tune after you make significant changes to airflow. Maybe with a paper filter it's not enough, but it sure was with my K&N replacement.

OK,here's one for ya.Took my trap out from the first week I got it(5000 mi now) and my car runs a bit better than my wife's.Revs quicker and pulls better at high RPM.Go figure.

I think I may be on to something with that last statement. One without the other may be the key. The H-trap by itself isn't enough to trip over the line, but combined with a freer flowing filter, it is

How many runs did you make with it out?

I gained 2 HP on a warm run after removing the trap and 6 HP after we let the car cool down.

Can you explain exactly where it is and how to take it out.

Blk05GT

It's behind the air filter. Take a pair of needle-nose pliers and slowly work the the thing out. Very easy. The 05s have been running rich from the factory so just removing the trap shouldn't cause any problems. However removing the trap along with changing the filter might lean it out enough to be an issue as SixtySix pointed out.

Has anyone else heard the term, "leaner is meaner?"
Just figured that if you took the H/C trap out and installed a K&N filter you wouldn't be adding enough air to make the car significally lean.
Yes, you are improving air flow, but you aren't increasing boost.
If the stock settings on the 05's is rich, then it seems like you would either be neutralizing the setting or running slightly on the rich side(which I doubt) making more power.
After all, the more AIR you mix w/ the fuel, the more power you are making...yes you do have to add fuel w/ air, but we aren't talking about adding power adders (N20, Turbo, Superchargers).

I believe the computer adjusts the fuel up and down at the wrong times just to confound us.

This is my opinion also.

:worship: Hey thanks alot Tim. :worship:

Fordracing200

if you take off the air filter all together, it loses rwhp. and sixty six, i meant that it doesnt lose power.

jwede

The Mass Airflow sensor will read the extra air and adjust the mixture accordingly. If you have a vacuum leak after the MAF sensor, you will run lean.

I don't see where less restriction will cause a lean situation.

yikesaz

COPY THAT.
It's like the difference between Sea Level & 6000Ft above. The computer should adjust for a little more air......unless it doesn't like you.
