Think this guy may be fulla BS but had a 2.7 with no tin and claimed no matter how hard he ran it, the temp never topped 210. Had no front mounted cooler, just the engine mount cooler.
So is he full of it, or are the rest of us stoopid? (No Rick, you be the stoopid one for not calling his BS) |

I've seen quite a few 914 track cars with no tins or engine shelves. Shrouding and cylinder dividing tins only. The 914 engine compartment is far larger than a 911 and also has a larger source of intake air. The biggest drawback is dirt and dust collection above the cylinders which will accumulate on the cooling fins. Forced air in the front top of the engine and exhausted out the bottom and everywhere else for that matter.
I ran this question past a couple of people a few years ago. Dave from TRE and also Mac Tilton. Both agreed on the dirty air issue but history proves it isn't really an problem on a mid engine car. Look at all the old mid engine Porsche race cars which had nothing except shrouded fans. Those cars had way more heat going on than a street car. 911's on the other hand are very different. Air is brought into the engine compartment from the tail of the car then forced through the engine and pushed out the bottom. If the guy with the 2.7 is in a 911 I would call borderline BS unless he has removed the decklid. If its in a 914 I would not. My build was based on low weight so shelves and tins are removed which was based on research. |
