That's really interesting that they added a variable fuel pressure regulator for the 2.0L. I'm sure both could have used it though. If I ever get around to installing the kit, I've thought about using the cold start injector as a fuel enrichment source on boost. The variable fuel pressure regulator seems like a better idea though! I wonder how much additional pressure it added on boost.

I’ve owned many Corvair Turbos over the years and used one as a winter car every
year when I put the 914 away for the season.. It did have a primitive system, but it worked pretty well considering the era and the fact it was in a production car.. It had a pressure retard in the distributor and also didn’t need a waste gate because of the size of the carburetor, exhaust housing and exhaust system limiting boost. Sodium exhaust valves and a nitrated crank helped it survive also. Different compressor impellers, exhaust scrolls and Weber 2 barrel carb adapters were readily available… As well as oversized forged pistons.. I still keep a turbo setup on a shelf above my workbench. My 930 was a very different animal and I did use one those Hobbs pressure switches To control an alcohol injection system for it when I bumped the compression, put in SC cams, changed the spring in the waste gate and twin plugged it…. |

"and the fact it was in a production car." you said it. about 7-8 years at least in front of porsche? they were pretty good those corvairs. not many of them down here in aus. very handsome cars. its a low pressure set up in the corvairs? i don't know anything about them. but they are fascinating. |
