Thinking of creating a 33 Compressore. Any suggestions in terms of performance/cost/availability?
Performance should be interesting coming from the 1.3 engine, which is really asking for such a mod!
My brother and I are currently trying to solve the air-inlet problem, which is simply in the way. This also goes for the water pump and alternator.
The extra pully on the crank could power the thing; were the Alfa engineer's trying to tempt this or what? Just how can we fit it in?
We will probably also need a 16V gearbox, OMP clutch, new pistons for decreased compression ratio and a remapped chip. Not to mention Integrale brakes (all round?).
We think that a compressor will be more suitable than a turbo in terms of flexiblity; more power lower down the rev-range. |

Hi,
I think you will need to use a toothed belt that is a couple of centimetres wide. I suspect you would snap belts if you tried to use just a normal V belt or similar. _________________ Scott Sander

Just get a 16V engine - surely? _________________ Hugh B

Wouldn't this be easier. See article at www.autoseed.com/cms/A_1117/arcticl.hmtl which talks about dropping a Subaru EJ20 turbos into an ALFA 33. This should give 200 horses and according to the article is reasonably easy due to the fact that the alfa like the subaru has a NS flat four engine and there was plenty of width to squeeze the subaru into. _________________ John H

A guy I worked with suggested Eaton superchargers as a good "pice of kit". Info can be obtained from http://www.capa.com.au/eaton.htm _________________ John H

Thanks John and Hugh,
I have already considered a Subaru engine, but would rather fit it into another 33 as a testbed (ie. locate a written-off Subaru with decent engine and shoe-horn the unit it into a mechanically dud 33 P4)
A compressor mated to an (Alfa) boxer engine should make a fabulous noise and would also present an interesting engineering project.
I will first have to consider insurance and road-approval in the Netherlands.
I shall keep you posted on the project.
Best regards
James |

Hi
There used to be a supercharged sprint about 1 mile from my house. The supercharger lived on top of the engine in line with the crank. It used a single SU carb and sucked through that. Then had 4 outlets from the supercharger with one pipe going to each inlet. The belt to drive it was only around 2cm wide.
By the way the 16V and 1.3 gearboxes on the series 3 have the same gear ratios, just that the 1.3 has a lower diff ratio.
All the best
