To be honest in 5th gear at that sort of revs these cars don't tend to like being up there that much. For 19psi i'm wondering if the intercooler isn't working as well as it should do, with the ignition as you are running slightly higher comp i would maybe give it a few degrees or retard and see how that goes.

Yes, I drove yesterday, in 4th gear at 6500rpm and in 5th at 6000rpm I listen pinking/detonation (with stetoscope) ! And I looked the AFR, and it rises up 12/12.5..... before I've 11/11.5 ! I think I empty the carb.....

I will try with a little pump and big needle valve, otherwise I will try with few degrees of retard on my renix 209

Thank you :wink: !

It would be cool !! Take 7000rpm in 4th gear without problem (200-210kmh) and take 230-240kmh in 5th gear !!!!! :twisted:  :twisted:  :twisted:

But with our heads of shit......... :evil:  :lol:
