Final numbers:
As some of you know from reading this (or other sources) the sedan's fuel assembly is not the same and can't deliver as much fuel as the coupe or Z.
So with that being said, on crappy AZ 91 pump gas we made:
538whp
490wtq
This was at only 13psi and easy timing. Yes 13psi! The car could make more with additional timing but Tony tunes very conservative to make sure the motor will last.
I'm going to do a race gas tune but it won't be that much higher, maybe 30-50hp more. Since we are pushing all the fuel up from the tank possible right now additional modifications will be needed to get more from it.

I have no idea what he ever put down. I'll have to look over on my350z to see what he did. I think it is. I can't wait to put a little race gas in and see how close we can get to 600 before I upgrade the fuel system.
This thing is stupid fast now.

Congrats. You have the fastest sedan in the country

Take it to the drag strip and throw some drag radials on it

If I upgraded the fuel system I could see around 600-625whp but that would be on race gas. Above that the sleeves become an issue, well at least for me they do. I don't think anyone knows the real limits.
If you had a Darton MID sleeves kit w/ no fuel problems what would it make on pump gas? Do you think it would make 750-800hp?
And what kind of motor and transmission mounts do you have?

Maybe. I have seen some amazing numbers with the right mods. That is above and beyond what I want to do with my car. This is insane as-is! I'm going to upgrade the fuel system just to make it bullet proof.
Motor and transmisson mounts are oem. I could have gone with solid but I'm trying to keep it as smooth as possible.
