information on IC
When talkn about intercoolers, is "bigger" necessarily "better"?
I'm going custom and so far here are the plans of what I plan to get:
Garret T3/T04E .57 trim .63a/r stage 3 wheel
Inline Pro T3 manifold
Garret type s BOV
Tial 35mm wastegate with .45 bar spring
These are the main topics right now. Still researching the other stuff like fuel upgrades, engine management, internal work.
This will be fitted onto a 00 civic Si, and I want to keep my a/c.

Re: information on IC (4-banging)
No, bigger is not necessarily better...Easiest way for you to find what you'll likely be happy with is search this forum and see what others are running etc...I've seen people list core size plenty of times. There really is alot to take into consideration when picking an IC.

Re: information on IC (AfroPuff)
how is bigger not better? Bigger = less pressure drop. As long as there arent any bends in the ic, bigger usually always is better. Bigger adds turbo lag tho.
Bigger ic makes the air flow thru it slower which gives the ic more time todo its job..

BTW You answered your own question...introducing too much volume into the intake system presents more lag. All that volume has to be pressurized before you get any positive pressure into the motor. You can't just say bigger is better...There is a proper sized IC for every application, figuring out your volume requirements would be wise.

The size of the IC has absolutely nothing to do with pressure drop. Pressure drop within the IC itself is determined by turbulator density and design. (how can there be a bend in an IC ?)

Re: information on IC (rjardy)
pressure drop is psi in, psi out @ given cfm
the air velocity can be effected by dense turbulator design (denser slows down the air so that it can be cooled for a longer period of time) but not by volume...if you've got two IC's with the same identical internal design and one is simply bigger why would it exhibit more pressure drop ? It wouldn't...the air is going to flow the same regardless of the size.

Re: information on IC (AfroPuff)
And btw, some pressure drop is good, the pressure drop from hot air to cold air that is An ic will always have pressure drop if its doing its job correctly.

pressure drop = psi in, psi out @ given cfm
Temperature isn't in there anywhere nor will it ever be. The industry doesn't measure pressure drop based on air temperature. If you want to talk about thermal efficiency then that's a whole other discussion. Pressure drop and thermal efficiency are two different things, treat them as such.

Re: information on IC (earl)
what brand are those IC's? I'm guessing that 24" long is the norm and 3" wide. But 10.5" and 8" would be decided upon fitment issues??
Thanks for all the replies guys (most of it was over my head
)...

Re: information on IC (rjardy)
so you are telling me that if i filled a ten gallon drum with 10 psi and then transfered that amount of air that made 10psi in the ten gallon drum into a 500 gallon drum, it would still be 10 psi? it will take more volume to make the same psi in a bigger area. so i think that pressure drop would occur in a large IC. some one straigthen me out if i am way off here.

Re: information on IC (C-Redrum)
I have a Spearco 24x6.5x3.5 and ive seen it flow 500-550whp plenty of times.....
Whats the difference between Spearco and PWR? Spearco seems to be a top brand here??

Thats exactly what I'm tellin you...you can pump 10psi in the 500 gallon, it'll just take longer to fill (read: introducing lag into the system like I said earlier) but hell it's still going to be 10psi...

Re: information on IC (rjardy)
i see what your saying but still there would be allot more air envolved in 500 gallons, so yeah the lag makes sense.
