    Anyone ever fit Treadstone trv 1859 IC into Omni?

    Looking at intercoolers for my 37K mile 88 Omni. I have a NIB 1080 CFM Spearco, but looking for something maybe a bit larger. The Treadstone 1859 is similar to the Spearco 1080 CFM but it has a 9X18.5" core instead of the 6X18.5" core. Anyone ever tried to fit one into an Omni behind the grille? Obviously going to have to do plenty of mods to core support, but taking some quick measurements it just may fit. It will be close. That appears to be about as big as I can go without getting into something semi-custom made like I did for Quacks Masi GLHS years ago. Anyone have a contact for good custom made coolers?

    That would be cutting it close. Mine is bolted directly to the upper rad support on the drivers side and I have about 2 inches or so of clearance to the core support. Mine is 12 inches total height compared to 15.25 of that treadstone. Mine has mounting tabs like the spearco so it loses probably an inch of clearance just for that.
    It's still not permanently mounted it yet.

    I don't know, but I would be interested to find out. It would certainly be as tall as you can get in there. It sure would help to keep charge temps down.

    I'm wondering if the bigger treadstonee will be as effective as the smaller spearco.

    I am wondering the same thing. Less transfer tubes (by quantity), but obviously 33% longer. Another question is with the larger 9" core of the treadstone, will the radiator perhaps see a bit more airflow vs. the Spearco?

    Humm, I see the Spearco now makes a 9" version of their 6" 1080 CFM intercooler. About $250 more than the treadstone. Part # 2-221a-3c
