2.2E vs. 2.4E Performance

[Tim Walsh]

hal,
Let me know when you're coming by. You're welcome to come by my home home and see the 'turd. I'd love to see the 2.5 as well.. It's one of those early screamers that I really like.

I have both a 71 E and 71 S. When the S hits 5k its just so much fun, but the E is not that far behind in terms of performance. I will have a look in the E handbook later today.

old thread but a 2.2E MFI stroked to a high-comp 2.4E rebuild with all else unchanged was dyno'd on Thursday. CR was 9.1:1. Torque was 160lb/ft from 3,700RPM almost horizontal to a 165 peak, dropping off above 6200rpm. Hp peaked at 192+hp, at 6,400rpm. On a dynomite, SAE. will post data later. Sweet!

I would love to see the plots. This is the EXACT engine I am building for my '71E sporto coupe.

flywheel SAE. this was the first run, the best run was 192.5hp. Overall, not bad for an E and a mere 2.4.





was told that the bump below 4K is the load coming on.
