Maybe this is just something for you to ask about in class tomorrow.

perhaps all this depends on the wastegate? does the wastegate operate on absolute pressure?

maybe the losses are negligible.

I would just like to take this moment to mention that Hieu's process of making this post was a fail on his part. :D

I'm going to stop thinking about this tonight... Hopefully it makes more sense in the morning.

aen

damnit.

at the very least not as bad as a supercharger's loss!

ill be watching the boost levels as it gets colder out here... i figure that's more feasible than watching for altitude changes... :D

aen

dude you should make a ____load more power when it's colder.

i sure hope so! but id hate to only race people on the basis of the time of the year... :D

wait... thats going to suck to have to get a tune on. how do i get a tune on such different numbers? unless its not really that much and it'll be fine?

i got it. ill have a summer and winter pulley....

that was a joke...

missReni

Har har?

Good point, do you know anyone else that's had to tune with such different numbers?

rod. his turbo should have made 7psi but he's not complaining with 5psi, but his tune will take 7, despite being for 5.

aen

if i was tehre and you had a f/ic i'd street tune for you

missReni

But will that work for your s/c?

missReni

Well, half of that is going for him... So where are you? ;]

i have an f/ic. you mean just tuning it on the fly?

aen

tuning it while you are driving me

yea i could do that.

Mr_Meaty

I'm a little late here, but colder air will make more power no matter what type of FI or NA you are running because the air is denser so there is more for the fuel to mix with...which is why we benefit from an intercooler.

At higher altitudes, the air is thiner so you make less power...not only that but atmospheric pressure is lower at higher altitudes so even if you make the same power, you don't reach the same amount of boost, so you make less power.

The guys in colorado always complain about how they woudl make much more power in california.

yeah thats the consensus ive been seeing, through the 3am research as well... haha

so are conditions in arizona better or worse than here? i think you mentioned it before.

Mr_Meaty

worse...hotter and higher altitude, but not by much in either regard, so it's basically the same...meaning a tune in AZ would react the same, if not slightly better here.
