Well the 3rd try porting did the trick. Holds ~9psi to redline in 3rd and 4th.

1st attempt woefully inadequate.



Current porting with valley.



Sticker applied. What does MK stand for?

With the warmer weather, the stock radiator and fans weren't cutting it. FM stage 1 shroud fan/kit installed without issue. Gained enough room to re-install my twin core. Temps are more or less under control (~210F at speed 205F in town) but the summer heat is still to come.

What's left of a cut up OEM under tray is installed. Didn't seem to make much difference on or off. The old style BEGI/FM i/c fills the grill up and is really thick.

Water temps have been getting uncomfortably high with the pre-summer heat.
Some observations on water temps with my old style FM/BEGI intercooler under the following conditions:
- 40 mile interstate commute, ~80mph, a/c on 4, ambient temps 84 - 88F, cut up under tray installed

OEM radiator, thermostat and stock fans
- temps out of control, heater on full to keep temps around 225F

Twin Core radiator, FM Stage 1 fan kit, OEM 190F thermostat
- temps stable without using heater, 215-217F

Above with gutted thermostat
- temps stable 205-207F

Above with modified high flow 180F Motorad thermostat
- temps stable 200-202F

Motorad 2040-180 - slightly larger opening than OEM and appears to open further.

Interesting to see such a difference with the high flow thermostat. Seems like a reroute would still be a good idea, It's only gonna get hotter (because Florida).

Spal fans suck up a lot of current on start up. AC and two fans coming on at the same time gives a noticeable hesitation. Relay delay module (Casper Electronics) wired into the coil side of the AC fan provides ~3sec delay and helps quite a bit.

I use that relay for my fan as well. It's a nice feature to have.
