Without external cooling you are limiting the possibilities greatly. I had some radical thoughts but those require some nice coolers to keep things in check.... That's the subject of another conversation, perhaps for that 71 E PCA racer
 In your shoes, I'd opt to get some Nickies due to the improved heat management (material, extra fins, ...) and perhaps consider overdriving the fan (knowing that there is a possibility of cavitation). I'd also consider some of Sherwood's heat barriers (anything to keep heat away from the engine) and perhaps some creative use of underbody airflow. In this app. I think squirters would not be a must but would be nice and can't hurt).

John,
Remember, the fan ratio can negate the necessity for a front cooler on a “small” engine and you can change back & forth fans & pulleys without removing the engine. I have 1.82:1 on my 2.0 and 2.8S (of course the 2.8S needs the Rubbermaid Solution for track.) Best, Grady

The engine that I put in my 914 has a 2.4L crank with the 87.5 mm pistons with the Nickes. It has 46-40 valves with 36mm ports. GE 40 cams. I have 10 to 1 comp. I have not finished tuning it yet but is making 170whp and 160wtq at 5800 rpm. I have not dynoed it past that yet. I also do not have the 36mm manifolds for the carbs yet. Still looking for some. I hope to see almost 200 hp at the wheels when all is said and done.

Spray water from a tupperware tub onto the cylinder heads or into the fan.

Have anyone tried Cheap Cylinder/piston sets?
Hi ,
I am Restoring a 68 911, The body has been lengthened to 69 spec, and is near all complete. I’m now turning my focus to the engine. I have a 2.2 t all in tact that has been running but is need of a ring and valve refresh. I also have a 2.4E that was rebuilt several years back but the previous owner let water get into a cylinder which cracked one cylinder. My question is has anyone used those cheap cylinder/pistion set found on ebay? My preference is to have the 2.4E as my engine. I also see 2.2E cylinder/pistons sets for sale will these work? I appreciate your reply |
