New 2.8 Liter Six for the Racecar, I'll be asking a bunch of Conversion Questions Options

[motorvated]

The first question I have is related to modifications to the engine shelf pieces required for the 6-cylinder conversion. I noticed the Patrick Motorsports sells an expensive engine shelf kit for the 6-cylinder conversion. But, since the 6-cylinder is going into a Racecar, can I just cut out the entire engine shelf to maximize the available space in the engine compartment? Or, has anyone made a template that can be used to modify the 4-cylinder engine shelf to accommodate the 911 engines? I'd like just to remove the shelf parts if they are not needed. Thoughts on this? How do you other racers handle this. Many more questions to follow. I know there are many conversion threads out there, but it's hard to weed through them to see if they address the question(s) that I have. Plus most of Tigre are for street car conversions, not race cars.

The motors create a lot of heat
Your about to double your HP. So you’ll need a lot more cooler than your old motor

Additionally the cooling at our altitude and humidity is not so great
I run 3 oil coolers on mine with two of them up front
(A 4th cooler on the transmission)

Rpm also contributes to the equation

I’d be very surprised if you didn’t need a front cooler cooler on an air cooled racecar

So what size front oil coolers are people using and what size oil lines, and running lines through the longs? Also what size for the 915 transaxle cooler? Any additional protection on the front of a front oil cooler to eliminate the possibility of damage on the track, like a screen?
