Its actually two of the 10x12x4.5 cores welded together. So its 10" tall and 24" wide and 4.5" thick.

That must be vertical flow ?

Yes it is.

ok cool.

No doubt the Garrett is nicer but I didn't think sub 140 degree IAT was too bad from a $300 cooler on 27+ PSI on my old setup.

Just for ***** I went from no intercooler to the Treadstone and it dropped IAT's from 220+ down to mid 120's. So while I know the Garrett works well it's also more then twice as expensive as the Treadstone. However, I'm not sure the Garrett works twice as well for the dollar spent and on E85 I'm also not sure the super cool IAT's are really needed. For an unlimited budget build I'd have a Garrett core in a hot second, but I would also have a lot nicer engine! For a clapped out 5.3 build and cheap turbos I think the Treadstone fits right in.

For those looking at these results factor in the cooling area on the Garrett core increased 28% over the Treadstone. That 28% larger core resulted in being 32 degrees cooler at 17-18PSI.

Would be nice to see a comparison with a similar sized Treadstone to see if it splits the difference and if 16 degrees is worth over double the price?

Yes its a little bigger but that's the closest I could find at the time. The Treadstone core is 350.00 and the 2 of the Garretts is 554.00. I would gladly pay 204.00 more for a better performing intercooler that nets more HP. I feel like the treadstone was becoming worthless over 24psi on my setup. Especially during the summer when starting IATs are 100* and its gaining 80* above that. My timing table starts pulling at 150* so less timing on top of less dense air adds up to a lot of power left on the table.

Did you happen to have a pre intercooler pressure tap at all? Just curious of the delta on both. Thanks for the data.

DBRODS

I didn't when I had the treadstone. I assume the pressure was pretty high since the turbonetics wouldn't make anymore power above 31psi. Since switching to Holley dominator and PTE turbos I added a pre sensor and pressure is even at 37psi.

Understand, however it seems most in this market are looking for cheap complete intercoolers that work well enough. A lot of people use the TR1245 that comes with end tanks without needing fabrication. If we factor in fabrication the price rises a good bit in comparison. The Garrett intercooler I looked at they wanted north of $1000 assembled, another place was $1400 customized to fit better. While it would probably work better and gain a few hp its hard to justify when the $400 unit works pretty well and I haven't tapped out the current setup yet.

Personally I wouldn't pull timing that low unless you ran really shitty fuel which I doubt you do on that boost level. On E85 we don't pull timing until a good bit above that, haven't seen any negative impacts yet. I saw 240* IAT without an intercooler and I didn't start pulling timing until 200.
