Met some guy at a carshow today; he had put PMO's on his 911SC... something I was pondering/really want to do.... Main purpose to abandon the KTronic and get some 'feeling' added to the car by natural aspiration... Didn't know which route to follow the new (spain) Webers (40) or now the PMO's..was pleased the 'reissuing of the webers' but these PMOs seems like a good, improved/progressed engineering... Its not for racing still,just road going (its my weddingcar), but what PMO size for a ('82 SC)... Thanks for your brilliant uploading!
Fuel injection does have its advantages over carbs. If it were me I would have to think long and hard before abandoning a working FI system. The guy at PMO can set you up with the exact right carbs depending on your driving requirements. Thanks for all your nice comments !
It would work, but you may want to mask off the mating surfaces. I would also keep the powder coat fairly thin. It is possible to put a lot of powder coat dust on and make a thick coating, but this tends to flake off over time especially on smooth surfaces. I sprayed my entire carbs with T9 Boeshield which is a clear rust preventative coating that works really well. I spray it on almost everything mechanical nowadays and it keep creeping corrosion at bay on all the fasteners and aluminum parts. I drive my cars in the rain and occasional salt.
Not really. Twin plugs are used because the 911 has a high dome piston and when running higher compression and a healthy amount of ignition advance it is necessary to spark both sides of the dome to optimize flame front propagation and avoid pinging. Of course one could just back off on the advance but with a loss of power. Also twin plugging allows you to spend gobs of useless cash and makes your engine look really cool ;)
@@Porsche9elfer That makes perfect sense. I never thought about dome shape. Thank you. Now I feel justified in selling my kidney and some insulin to raise money for this necessary mod. ;)
