revhard or pwr....cons/pros and specs between the two.

thanks

There really is alot to take into consideration when picking an IC.

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..

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 ?)

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.

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.

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.

Pressure drop within the IC itself is determined by turbulator density and design.

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.

Pressure drop within the IC itself is determined by turbulator density and design.wtf is a turbulator, thats a first hahaha

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.

I have a Spearco 24x6.5x3.5 and ive seen it flow 500-550whp plenty of times.....

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...

i see what your saying but still there would be allot more air envolved in 500 gallons, so yeah the lag makes sense.
