I just recently moved from the bay area to Colorado and I noticed that there is a performance loss. I realize that Im in a higher elevated area and that the air is thinner here. I have the Joe Z intake and I was wondering if I get an f-sport intake box if that would help restore some of the power loss due to the more air that comes in.

im surprised you can feel any performance loss at all.
i honestly cant feel a 10 hp gain or loss.

 

yeah i think its all in ur head..... wont notice much diff in hp with intake ... all u get is noise lol somtimes is mistaken for power

 

install 2 rockets on the back of your car?

 

There's a pretty big performance loss from sea level to 5-6,000 feet. Around 15% reduction in total power at 5k feet (turbo reduces this percentage to around half this).

When I drove my 250 awd to the east coast, i was surprised at how much "faster" it felt, haha.

so in all, an intake isn't going to change much if anything. But everyone else loses the same amount of power (well, unless if you're turboed or supercharged).

 

For every 1000 ft. you will lose approx 9hp. So at 5000 ft. you will lose 45hp. You will feel the lose. Only forced induction will help!

is that true???


soo what about a place like where i am in canada its by the rocky mountains in alberta ... im really high above sea level i dunno how much(if theres a way to find out let me know pls )

how much hp losss do you think us canadians are losing?

 

I lived in CO for a couple years. I don't know if 9hp/1,000 ft is true, but there's definitely a significant loss. I seem to remember is being in the 20% range.

Changing intakes won't do a thing. It isn't the volume of air, but the oxygen content within that air. As someone said above, forced induction is the best way around the issue, but even FI cars don't perform as well out there.

In fact, I know Audi's reference altitude in determining boost. The higher up, the higher the boost... to a certain point.

 

Thanks for the input guys. I didnt think the intake would "fix" the issue but just help it just a little? But yea when I was in CA the car felt fast and responsive. When I was driving through Montana you can def feel the loss. The car feels less responsive and heavier in some ways. But all in all I guess I can live with the fact that my car is slower now :'(

 

Just like when I was in Mexico City and my track was at exactly 7,411 feet and where I lived topped 8,000 feet and 2,000 feet further up was my uncle's shop, that's 10,000 feet. If you can figure out how to do a ram air attachment I did this for my RX300), if you can't afford to do forced induction, this can help.

 

no the fsport intake box wont help at all, spend your money on 'show' rather than 'go'.

 

+1 time to buy things to make the car prettier

 

See for yourself!
