Quest4life Posted July 30, 2008 Author Report Share Posted July 30, 2008 Thanks, So will it even produse and real pressure at 20? I will split the difference at 15 and set the 20 for the days when I see pretty red and blue lights in my mirror. Just kidding, Thanks everyone.

Daniel Also, If you run a 12A to 15 psi boost. Better have a A/F Gauge installed and enough fuel to do it ,(Via a Fuel Pressure Gauge). An Adjustable RRFPR wouldn't hurt either. Remember this!!! The higher you boost a Stock (12a) turbo above the recommended limit,(7 to 10 psi) the shorter the lifespan is on it. If you want to boost higher safely, Install a turbocharger that has a boost efficiency range above the stock one. 14G: 10 to 19 psi. 16G: 13 to 20 psi. Super 16G: 15 to 25 psi. 17C: 10 to 20 psi. 19C: 10 to 20 psi. 18G: 16 to 25 psi. 20G: 16 to 30 psi. Some of these turbo upgrades require fuel upgrades also. Do some homework to find out on which ones and how much. CALIBER 308 Edited August 2, 2008 by Caliber308 Link to comment Share on other sites More sharing options...

Quest4life Posted August 2, 2008 Author Report Share Posted August 2, 2008 Thanks I do have a wide band which I monitor. I have an 18g which I will get back on as soon as I can afford to get it rebuilt thanks to a garage that wrecked it. I have a walbro 255 so I think I can get plenty of gas when I need it. what i Need is a fuel management system so I can add or subtract fuel. Right now I run @ 15 psi. just ran at the track tonight actually. I run 11.5 A/F @ 15psi at 10psi is is about 11.7 so the numbers are safe enough but I am not sure how efficient the boost is at 15 psi. I can notice a difference 10 to 15 so it does help. I wish I had my 18g on. Have a great day and thanks for all the input! Link to comment Share on other sites More sharing options...

Technology Posted April 29, 2012 Report Share Posted April 29, 2012 A mechanical aftermarket gauge will show you exactly what is happening.
