...warning, don't look unless you want a lighter wallet.





sweet, your 2 1/2" core is really a 2 1/8" core. Always good to leave a straight shot to the other side of your intercooler, less pressure drop and all.

 

Earl...what are those metal wire mesh thingies in the intercooler. You should pull them out for better flow.

 

LOL yeah you wanna see the end tank... look at this..... its like 5 inches by 1"... deceiving.... when I started my 3.5" ICs I had a chance to look inside as well... Ironically the sides on the IC endtanks are are barely even present... for shear purpose of fitting studs to the brackets... thus they reduced the sides of endtanks... I found a way to maximize every mm I could.. sorry if I hi jacked your thread... just wanted to add to your findnings

 

Look at how badly the OEM piece necks down in the 3rd pic - holy smokes! I really need to swap some parts....

 

Great photos Earl. I really was shocked at how cheap the OEM ICs looked when I swapped, pitiful. They were really restrictive too as I gained 0.1 bar of boost just by switching them out. I guess ECU was calling for more boost but could not get it past the ICs.?

 

Beautiful looking stuff Markski! The side by side is very revealing, great pics and work in the design!

 

This is not a wallet-friendly thread!!!!!!!

 

Yes but considering some of the stuff we by this is by far one of the most overlooked upgrades. That's I know for sure.
Cooler air =power

Fancy billet turbos alone will not do it. Lol

 

Here's the 996 (left) vs 997 intercooler. Albeit slight, there is a difference in the internal core as the 997 has about a 1/4" gap compared to the 3/8" of the 996.

 

the 997tt uses the 996 X50/gt2core... that's it...

 

yep, though some have claimed that the internal core is the same and the only difference is the additional fin length on the outside.

Neither appear to be great for a modded car

 

Nope..
especially if your running boost....
look at the IAts... thats on a 18 g car... same everything except the ICs got swapped.. at 1.15 bar....
before and after... nor am I trying to hi jack just showing that is does matter.. and thats only at moderate boost on a entry level turbo upgrade.

 

no worries! Any thread with datalogs is bueno. Random thought -one would think that compressor outlet temps on an 18g at 1.15 bar would be less than that of a K16 at the same boost, would potentially more temperature reduction benefits be realized with an intercooler upgrade in front of a less efficient compressor? Obviously flow rates are different but from a Tin/Tout perspective...

 

smaller turbos at 1.15 bar emit lots of heat... not sure the temps as I never tested it... but smaller wheels turn faster to produce that target boost and emit a lot of heat.. bigger turbos don't work as hard but do flow more lbs./minute... I tend to agree with you on that one...

 

Markski,

Would I have to cut out anything in order to fit those intercoolers ?
Also, would I need a retune if I were to get those, or would the ECU adapt
to the intercoolers ?
Last question, would I be able to use my stock piping so I won't have any
tyre issues ? I currently run 315's, in the near future i would like to run 335's like tom kerr as my car sees road courses alot, and I do not want to go through what Dave is currently going through with his custom intercoolers to fit 315s. This looks like a must after i'm finished doing my suspension.

TIA
