Its come full circle. I hate that you're having to replace it after all your research and experimenting but I am really looking forward to watching you catalog the process. Hope everything goes smoothly!
Condensor core has some bug smash goin on. Ugly but not enough for me to discharge the A/C system to replace.
Interesting, I'll put the Spoon Rigid Subframe mounts on my list then if they are that good. Actually, I'm planning on upgrading where I can on the suspension if the cost is reasonable. For the amount of labor required, I'd do as much as possible if the subframe is getting dropped anyway.
The CVT cooler I had in mind is the Setrab 9-20 Row Dual Fan Pack setup (FP920M22I), very nice engineering. It's pricey at $380 but comes with the fans too. I'll have to run thru the calculations again for the BTU heat rejection and all that but the core is 6" x 14.5" so it's quite massive but fits nicely in the stock FMIC location. We know the CVT get hot as hell and this setup is primo. The airflow should be pretty good, I designed an inlet skirt to force air thru the core.
The FMIC I'd like to run are either the Garrett 24x7.9" (10-row core) or the Treadstone 22"x7.9" (TR-82) core for $271. Not too big but they have enough cooling flow for 500 h.p. I ran the Forge FMIC and the power and response are great but the cooling isn't fantastic on those long highway runs. For the Mamba 19T flow rates the Garrett or Treadstone would work pretty well while not being too laggy.
