Since I am a pump gas guy, that question is better suited for Tym or Robert. Seems like I remember 25psi was a pushing it to the far end of insanity on pump gas in intial testing, but I can't remember to what rpm. I'd also say anyone is a fool to drive around at that pressure on pump... not suggesting that you would...

 

meth is my friend...

 

Works wonders for weight loss... errr, I mean detonation resistance

 

How high would you boost on pump bro?

 

IMHO, if you're running 93 Octane, then 23 psi is the max and that is assuming a very good tune with AFRs around 11.5 if not richer (less). IMO anything more is inviting disaster.

Thank you, and I assume the WR should be able to pull this off no sweat?

 

Based on the info provided by Zeus, 23psi should be no problem at all for the WR ... just make REALLY sure that you have a good tune to go with it before you try to push 23 psi on 93 Octane gas.

Yes, 23 tuned properly is my upper suggestion for the daily grind... people do more, but they are probably rolling the dice.

 

I'd like to see 23 on 91 octane. That would be fun Can you say BOOM?

 

Sorry, I'm used to here in Texas where "low grade" is 93 octane at your least favorite gas station

 

Wait, there's higher than 93 here?

 

I'm thinking 21psi is the ceiling on pump here in cali, although I may throw a few gallons of 100 in and see what this SMART tuning can do.

 

Meaning I've never used anything lower than my favorite 93...

 

You should really think about using water injection with your 91 octane. That's the only way I've been getting decent performance out of this terrible gas we have.

 

If someone's not trying to get me to go with cams, they're trying to get me to install water injection


I have to pay for a reception and closing costs on a new place. That means no cams and no h20 injection for now. 91 is all I'm running...except for that 100 map
