    Further detail on Cooling setup:

    For the cooling, I'll have the traditional 2 front “pusher” cooling fans. I’ve added a SPAL 16” “pull” fan to the rear of the radiator. I’ll have one master fan switch for all 3 fans that will provide power to two relays. I’ll always leave the power switch on (normal position) unless I need to turn them off for some reason. The rear fan will be controlled by a variable speed and temp controller, see link and description below. The rear fan will start at low speed at 180degs. The front fans will kick in at 200degs (off at 180 degs).

    Side note: I actually will have 3 switches that on in the normal on position (i.e., Fan, AccuSump and fuel pump). These three switches will have a flip-up safety cover, the switches will be turned upside down so when ON the switch lever is down, in the on position, and the cover closed. See the Interior, Dash Thread http://www.uniquecobra.com/forums/showthread.php?t=8225

    Variable Speed & Temp Fan Controller:
    http://www.summitracing.com/parts/FLX-31163/

    Flex-a-lite variable speed controllers attach on or near the electric fan, sensing coolant temperature via a temperature sending unit. I’ll set fan speed from 60 to 100 percent, depending on the built-in thermostat's setting. The thermostats have a range of 160-220 degrees F. The variable speed controllers allow greater control over engine temperature, which helps to reduce charging spikes and current load on the charging system. It allow a maximum load of 30 amps, and keep the fans running for 30 seconds after your vehicle is turned off.

    Thanks!
    Paul, I believe I found another reason why the ~4400 RPM starting point is a non-issue... while entering data specific to my car at this popular link.. http://www.gtsparkplugs.com/GearCalc.html
    It provides lots of data taking into account Eng peak HP, RPM range, tire size and transmission (TKO 600 w/.82 5th). In the chart below, I never drop below ~4300 RPM... so all my shift points are in the peak range.

    Gear Change RPM drop (change @6500)
    *************************************
    1->2 -2220 (To 4280 RPM)
    2->3 -2098 (To 4402 RPM)
    3->4 -1422 (To 5078 RPM)
    4->5 -1170 (To 5330 RPM)

    Paul... thanks for pointing that out. Brent, my engine builder, is really good and I hope his exposure on club cobra helps others you need engine builds or help. He's a wealth of knowledge for the entire drive train! The best part, he takes the time to talk and communicate with his customers .

    A little "Engine" addition

    You'll notice the black wrinkle coated/alum rib valve covers (picture above in previous threads) came with a breather and std PCV. I wanted both to look more like the valve covers.... So I searched and found these matching polished ribbed CNC's alum breather and enclosed PCV... problem was... didn't match the valve covers.... therefore, I sanded them, used acid etching heat primer and then a high heat wrinkle coating. I turned them upside down on a flat surface with 100 grit sand paper, followed by 320 grit, to remove the paint from the top of the ribs and flatten them a bit to better match the valve covers. Picts below of before and after.

    Most of the oil filter, accusump, elec valve and oil thermostat installed. One of the 2 oil filters is still yet to be installed. I'll run all the hoses when I get it. I'm going to install a single remote spin-on oil filter for the first ~500 miles, then drain oil, remove temp remote oil filter and then connect all you see. When I connect the entire oil sytems... it will add about ~6 qt's of oil (accu = 3 qt's,2 oil filters and oil thermostat = ~2 qt's and the oil cooler and hoses about ~1 qt oil) to the oil pan of 9 qt's.... therefore about 15 qt's of oil total capacity.

    engine bay complete

    I finished the final touches in the engine bay, spark plug wire runs, final LED brackets (they blended in well, hard to see them). I also had to shorten a set screw on one of the steering U-joints. The set screw was hitting the gas pedal linkage and would cause it to stick until I turned the wheel one way or the other.
