For the many that have gone the DIY route and sourced a EBAY core with custom piping, do you have logs of your IAT with the variance in temps? Do you experience heatsoak prematurely?
(Jedi94 or Kompressed feel free to time chime in) :D
Thanks

i have an ebay FMIC although I have no temp logs I can tell you there was no boost drop and I hold boost alot better than I did with the SMIC

My ebay cheapy is fine. no problems at all. As of yet, no heat soak either. Unfortunately, I have no IAT logs before or after. the specs are 2.25" in/out, 2.75 thick, 21" endtank to et, and maybe 7-8" tall (not sure on this one). I have 2" hot side piping then 2.5" from cold side to the TB. I think that helps alot w/ keeping IAT's down. That was k0mpressed's idea. I'm very happy w/ the results. I think I did everything for right about $450 but if I had to do it again, I could get it down to $350 because I'd be a little more savvy this time w/ my purchases.

no name cores have poor efficiency. Spearco, Precision and sometimes Garrett cores are sold on ebay and are good cores. backpressure and transfer efficiency are the major differences, heat soaking is more a product of the material type, ducting and volume of material. larger cold side piping promotes flow through a core by lower backpressure discouraging pulse stagnation in the core

yea...but remember that includes everything from turbo outlet to throttle body. everything. Oh that also includes some silicone & hardware I needed for my TIP and intake piping.

With that being said most precision and garrett intercoolers I have seen are 3.5 wide... YOWSA... I have a S4 bumper. With a core so thick i would imagine that bumper support will still need to be cut to sh!t. All in all it may still be overkill for my use because I don't plan to track the car often.
Do they have garrett or precision cores that are 2.75.


EVEN the precision 350 is 3.5" thick... [eek]

I have no idea, I bought it from k0mpressed w/ a pre-welded mounting setup for a song. maybe he can shed some light on the brand??? It's fine though. holds pressure, no noticeable press. drop. no problems really. for my homebrew setup, it's perfect.

high octane, did your core come with piping? if not, where did you buy? was there any trimming involved with your bumper?
