After a 3 month break she's back home:
The car was a pig to drive below 80 mph (overfuelling, missing backfiring etc etc) after which it went like a scolded cat - great for the track but not much use on our great British roads so decided to return the engine to a more 'user friendly' 2.7RS spec.
Work undertaken by Bob Waston Engineering:
- remove the 'raised' 965 injector stacks (poor mans high butterfly)
- relocate stacks back to factory position
- reposition injectors back into the heads
- rebuild RS spec MFI pump
- replace worn cams & rockers with S cams & 930 rockers
- gas flow & twin plug heads (for future use)
- skim barrels and raise compression ratio to +9:1 ish
- new rings/gaskets/chains/studs etc etc
Bob's somewhat conservative rolling road shows she is now producing 220 hp which is consistent with a good 2.7RS spec engine and although I haven't had an opportunity to test her legs the car is transformed, pulling cleanly from low revs and spinning very quickly onto the S cam - so far I'm delighted with the new engine and at last can actually enjoy driving the car below 80mph.
Next stop will be to complete the interior, recover the Scheels, refurb the factory 9"/11" fuchs and then negotiate the divorce.
