Max boost

[askoncemore]

What is the max boost the factory SHOFlex turbos are capable of?

 

[BiGMaC]

17-18 psi ... Less when ambient temps are lower.

What options are available for upgraded turbos?

 

[SHOdded]

One option:

So who is running these?
What is your max HP/TQ?

I've had my turbos up to 25 psi with meth. No issue yet.

These are upgraded turbos, right? 

I'm confused as to why meth injection is an issue in this case?  Aren't you injecting into the post IC charge pipe?

There's no issue with meth. They are stock turbos on my car. Without meth the boost at higher pressures would also be at very high temperatures. Which is not useful.

What do I need to do to get more boost?
Is there something needed to have Torrie increase the boost to a higher level?

I am seeing 16-17 psi with the 50/50 meth.

Don't want to start anything but we have only one person that claims they are running 25lbs of boost on stock turbo no less. Guys that have modified turbo's and make over 600whp don't run that type of boost. Why that is? I don't know.

Boost is determined by many things... But more boost is not necessarily more HP... I remember Dave's Dyno tune with Dan Millen earlier this year... ended up with more HP than he ever made... and 20% less boost used

 

[crash712us]

Correct. I am just not going to speculate as to this specific situation.

Max boost or sustained boost, wasinger?

 

[FoMoCoSHO]

I'm curious about ambient, cac, and iat2 temps at this boost level....

It's not a "claim" it's a fact and I've seen it numerous times in a mechanical boost gauge. It is not sustained boost at 25 psi. It is a peak number. I'm not saying it's making more power or that it is what people should be running. Simply saying these turbos can and will produce 25 psi.

Here is tonight's screenshot...

Chilly out...

Is there any more power left in the tune to be had?

Thank you.

 

[Josephm]

Doing any e85?

My statement does not negate your "claim" And is exactly what I wanted to avoid. But your continued posts of 25lbs of boost makes other think there is something wrong with there cars. Spikes are irrelevant and prove nothing, stock turbo's are capable producing boost pressures into the 30lbs range. But again irrelevant, cause it well beyond the turbo's peak efficiency. Max boost means absolutely nothing, its the volume of air that turbo can displace efficiently.

Do you have results to the track with 25 psi run?

Where would you consider efficient?

I'm thinking 13 - 14?
