I've been following Michele Abbate (SCCA STU racer and 2015 SCCA US Majors Tour Western Conference champion) and a few other Edelbrock SC owners who track their cars and so far the LTR is sufficient given the coolant is mostly distilled water and Amsoil coolant booster. Properly ducting the incoming air straight into and through to the LTR and other heat exchangers is critical as well. Nothing some sheet aluminum and creative cutting with shears can't handle.
I've also seen logs of the intake temps being significantly lower with E85 running on an EForce kit at the track as well. The heat soak will likely become a bigger issue with smaller pulleys than the stock 3.25" pulley that makes ~10psi.

I follow them on here and on Facebook and I'm very confident in my Millers gear oil's ability to put up with temperatures like that, but I do still want that Harrop diff cover to keep more fluid in there and help cool it down.
