Please post your year, type of boost, psi you are running, hp and any other info you might have. I am having a disagreement and need to show some proof, seems people do not believe the Maxima can run on 10-12psi on 91 octane, people are calling it "overkill" and saying it could only do that in "spurts". Please check in.

 

NOT boosted but;

10-12 is NOT overkill. Its a high amount, but not extreme. I know of 1 turbo max that would spike to 14psi - and another one that was dynoed at 16psi.

As long as it's TUNED right, there really shouldnt be too many issues. The air/fuel mixutre is what determines the life of the motor

This might be the best place to find that.

Nice tread. To bad they don't have SC's or TC's for the 6th Gen. I am running about 310 hp at the crank. Injen CIA, Racing Pulley and Greddy SP-2 Cat-Back System. I just had a CE Y-Pipe installed and will have it dynoed when I come back from my drive to Florida. Later Warren

 

With the right fuel management 10-12 psi is not that big of a deal, as far as what the motor can handle. You could blow a motor on 5psi, it is how you have it tuned. I would be more worried about the tranny on a 12lb boosted maxima and the motor.

I would agree that 91 octane is not ideal, but with some timing retard it is fine. I don't think I would want to run 12lbs of boost on a hot day with stock timing and 91 octane.

Then there is the difference between 12psi on a turbo maxima and 12psi on a SC maxima. You can get away with alot less with the SC. [B]In general[B] 12 psi on a SC max is worth 325-350 hp and about 250-275 torque. 12psi on a turbo maxima, in general is more like 350-400 hp and 350-375 torque. So the question needs to be more specific as to what type of boost your refering to.

 

97 - T4/T04E 60 trim/ ball bearing.
Previously ran 12 psi street, 14-16 when I got greedy @ 91-93 octane.

 

Donald. 1st of all, use the correction section. 2ndly, you KNOW there are guys running 10+ psi on pump gas. Research and you will find it.
