Nissan 370Z Forum - The 370z Useless Thread (Coors Lite version)

This actually made me laugh out loud...

well maybe not quite out loud...

actually it was more like a chuckle....

In reality I just breathed out...but at least it didn't make me stop breathing!! :tiphat:

you're right on that. I mean ultimately I have read/see/learned that the best AF mix to try to reach is between 10.5 and 11.2 giving you the best output w/o risking some kind of interior destruction. Or maybe that's just with FI. Can someone clarify that?

For our car (or any NA car) you want around 13.

don't listen to rreign, he doesn't even have a Z :rofl2:

lower air to fuel ratio is running richer

doesn't change the fact that I've done more research and learned more about the Z than most of their owners:icon23:

So that is just FI then?

you are stuffing a whole lot more air in the combustion chamber with FI, so I could believe that they need to run with a lower A/F than NA to keep the car safely detonation free...but I don't know the numbers for them off-hand

Yes, for FI you want to be around 10-11 I believe.

Those were the exact numbers I was given by them but we were talking about different motors. Some good ole american muscle, the 2JZ-GTE and the RB series motors.
