Do you guys think Bar & Plate style fmic are better or Tube & Fin? Which manufacturing technique offers better heat exchanging properties? Many factors go into this comparison so lets compare the 2g Greddy tube & fin big fmic to 2g Slowboy bar & plate big fmic. Also keep in mind that the i/c piping design is different. Slowboy has a shorter distance from turbo/fmic/bov/throttle then Greddy because Greddy utilizes the area where stock intercooler used to be, then upper i/c piping goes to throttle. Which one do you believe is better even though both are very good fmic's.

go to your control panel and activate your PMing. I am trying to pm you but it wont let me cuz you havent done it yet!! call my phone if you got a question about it.
Greddy offers 2 core choices in their DSM applications. 1 is a V Spec and is your "tube" design, and one is the R Spec and is you "fin" design. The design is both of them is set for differant applications. The V setup is used more for factory sized turbos with a little more boost and the R setup is used more for those big dick slinging turbos. They are both basically tube and fin design cores, just have a little differant design and thus used in differant applications by those who do buy specific for their application.
A good bad and plate design is generally able to hold more pressure and is generally built for maximum performance with less pressure drop and usually has more "uniform" dimensions. Generally the way to go if it's a well built core in my opinion.
And tonight I can't sleep or spell at all.

Both of the GReddy FMIC's for our cars are the R-spec cores.

Hes running a greddy right now... it kinda has a long piping route back home. So he is wondering if there is any way to get more power out of a slightly ( or highly) different intercooler setup. Looking for over 500 whp, so whatever would work best for that...

The Greddy kits are ok. They are fairly inexpensive compared to the better kits out there. People have made decent power with the Greddy's, but you would have a hard time finding a kit that didn't perform better, unless you made one out of some of the cheap cores sold on EBay. If you really want to make power especially on pump gas, then get something better then the Greddy.

Aside from the core not being all that good with the Greddy, I have never liked the way that the piping goes out through the passenger fender. Or can you get kits that don't do that, all the ones I have saw it seems like the UICP would be kinda restrictive.

Since Greddy was one of the first to put a kit into production for the 2Gs they tried to make it as easy to install as they could and obviously it sold. But now with all the custom short route kits and one off designs the Greddy and APEXi kits are not the greatest choices anymore unless you score a sweet deal on the core and have custom piping I'd skip them.

he always is running c16 if that matters. Hes looking to break 500 whp next year and is getting a bigger turbo and was told to do something else with his IC and piping. Hes mainly concerned with the 2 different TYPES of ICs, and the way its routed. How much does the piping hurt / benefit for performance? Sizes.. routes.. length.. material.. etc.

Well 2.5" piping is widely the most popular diameter piping that is used. And obviously you want the least amount of bends and the shortest route possible. The least amount of "walls" that air can hang up on the better with turbo applications especially.
The smaller the piping the more restricted its going to be as well. Some people go with smaller piping (like 2") to make more torque. For a daily driven pump gas car this wouldn't be a bad idea, however you are not going to be able to make big HP numbers as you would with bigger size piping.
In your friends case, if he is trying to make 500hp and is running C16 with 30+lbs of boost, he should use the shortest route piping and use the atleast 2.5" diameter. Also if he is using a aftermarket intake manifold, a bigger throttle body would not be a bad idea as well.
The basic idea is to let the air go from the turbo through the intercooler up to the intake manifold and into the motor as easily and efficiently as possible. There are numerous variations to achieve this, you just have to pick one that is functional and cost effective.
