Has anyone run a low compression 7.7:1 turbo ea82 without the turbo? I reckon ea82t goes OK before boost cuts in so wondering....

It runs 8.5 psi boost. That's about a 58% increase in power theoretically (58% of a full atmosphere which would give a theoretical 100% HP increase). Which means it's going to contribute approx a thereoretical 58%รท2 of the rated HP. Subtract 29% of the 115 HP rating of the engine and you are left with a little less than 82 HP. Which is about what you would expect being the EA82 n/a versions are around 85 to 95 HP. Lost compression accounts for the HP loss over an MPFI n/a engine at 9.5 compression.

So basically.... slow.

A little math is all that's needed. Boost performance is pretty easy to rough calculate.

Great if you treat them right i just did.some work on one for a freind and it gets driven all over the state through the sierras snow sand mud down to the beach at sea leval  there fun still they have the same limitations that all ea82 have there gutless and problematic but if you can take care of them and there little whinnie issues and you like to fix things there great engines
