I did a compression test on my LoveFab turboed NSX today.
The idea was triggered after reading [MENTION=18194]Honcho[/MENTION]'s thread "Long road to Imola"( http://www.nsxprime.com/forum/showthread.php/207052-Honcho-s-Long-Road-to-Imola-Type-S-Zero/page12) as I couldn't quite believe the results with an average of 190 psi corrected for altitude at 230 psi or 16,16 kg/cm^2!
The Honda manual states 14 kg/cm^2...
The other reason for the test was to determine if I kept the turbo setup and continue attending track days or ...move to something else.
Well the result surprised me as the readings were slightly over 16 kg/cm^2 totally in line with what Honcho measured.
This is with an engine that has had the turbo setup for 25 thousand km and previously a CTSC supercharger for the same mileage.
Hats off to Honda's engineers specially when one knows about Porsche's issue with their IMS ( intermediate shaft) that caused many catastrophic engine failures.
Here's the article (in french) that explains the issue: https://911andco.fr/comprendre-solution-probleme-ims-porsche-911-type-996-997/
I will now have the valves adjusted and the timing belt changed along with a new water pump for a few more years of fun chasing the Porsches!
