increasing compression, running on regular gas?

dremd; True mechanical injection has no electrical input or operation like the Lucas injection (i.e. CanAm 494 Chevy, Formula 5000 Chevy, 1971 Porsche 911E) it has a belt or gear driven pump, throttle linkage controled metering unit, and undividually run high pressure lines to each velocity stack. K-Jetronic is not that type of injection. Mechanical injection has no air density measuring, it is set pretty much on a flow bench or dyno by a tuner or builder. In the case of the street Porsches, this really was true mechanical injection and it was used in a street application till the K-Jetronic injection was interduced. I had one, was really neat injection, nightmare to set up , but ran better than webers (Solexes if stock) and stayed in calibration till you went to a diffrent altitude at which point you had to set it for air density. Once agian K-Jetronic adjusts for this via the air metering unit.

wow... there did this thread go off too...

EFI was not introduced on North American model watercooled VWs until around 1988 or 89.... Otherwise they were Carbureted in the first 70s models and Mechanical CIS Injection there after (Except some Canada models). Some VW (and Audi) models kept Mechanical injection until the early 90s... namely a lot of n/a 4-Cyl and basically all 5-cyl models.

For those that aren't egumicated on Mechanical CIS Injection.... A Technical Book by Bentley Publishers:

Our 13 year old volvo has done 190k miles on 87 octane with 10.7:1 CR. Its all in the engine management and its ability to adapt.

already covered page 1, ECU and Knock sensing are two things my engine doesn't have
