craig, jake does both. looks like i will be going back to using a FAT as jake is reporting a delay in the Sharpbuilt shrouds right now. i already have a FAT as i was planning on using a runner (like Sandeep) has done, but ran into some money and was able to go with a RAT sooner rather than later.
so jake will do either. the FAT is easier on him, but tougher on the car owner due to the decklid issue. i have some possible decklid designs i have been playing with just to do something "different". they are below. not sure how much any of them will cost at this point. let me get some votes so i know opinions for the hell of it.
the main difference is that FAT has the fan sit on top of the breather chimney and all others machine the chimney down to get the engine "shorter" to fit under the lid.
