Hello, some reading this may well be aware of my winter project, but posting on here just in case I can find out mote info. on making my 3.2 that is stock run out to 7500 or more.
The engine is in my 550Kg hillclimb car.
It has just been on the rollers giving 262 bhp.
I need to get this engine to run to at least 7500 rpm. It has PMO carbs, single plug heads and RS 2.7 distributor, no electronics in sight.
The engine is very fresh inside and is really good to use, long smooth power with strong torque.
So far, my plan is the following, but I will welcome any advice or opinions before I start spending money.
As I say, I need the engine to rev to 7500 or more, not necessarily make tons of power.
Pistons: Wossner or JE
Rods: forged steel, prob Carillo with their standard bolts or Wossner with ARP bolts
Cams: DC 60
Springs: Schrick, not sure about titanium tops
Rockers: no idea!
Ignition: possibly Clewitt, but will be machining the heads for twin plugs just in case which Clewitt and serve.
The engine will be a self build, this will be my 4th 911 aircooled engine.
