cant boost over 30??
Hey guys,
Ive recently been getting tunned for e85. i have and fp green with the 18psi wastegate. i have an evc boostcontroler and i cant seem to get the car to boost over 30 psi? wanna run 34 psi but for some reason only hits 30?? i installed a strong spring 30+ in my bov and even flipped it around thinking maybe i was loosing boost through the bov but it didnt help still could only hit 30. no matter what i set my evc at for example 35psi i will still only hit 30? the car doesnt have any boost leaks did a test but only brought it up to about 20 psi. i dono what would be causing this problem? i thought about throwing a manual boost controler on or maybe dont laugh but bleeder valves to my evc to make it boost more? or atleast try to get it to? but would rather find out why its not boosting 34 the right way. any suggestions i can try?? thanks! plus think putting bleeder valves would mess up the boost reading on my evc and my booost gauge only goes to 30 so kinda need my evc to be acurate

With your EBC are you setting target boost or adjusting the WGDC,
If your just setting target boost its most likely going to be just a target boost, i.e what the controller expects to see,
you then need to go through ur settings and increase the Wastegate Duty Cycles to hit that target boost

34 PSI is doable on the original Green. Why not? I seem to recall that there were pioneers such as Curt Brown, and Scott at TTP taking stock VIII turbos way over 34 PSI. This was way back when and maybe I am just imagining. So, why couldn't it be doable on an original FP Green? The Old Green wasn't even supposed to come alive until after 30 PSI.

You can try a two step elimination process to see if and whether it is your BOV, or your EBC that is causing the problem.
1) Block off your BOV by inserting a thin piece of sheet metal in between the BOV flange and the IC pipe.
2) Disconnect the EBC and run a length of 4mm rubber hose from the WGA nipple to the nipple on the compressor housing discharge pipe. Now increase boost manually by turning in the turnbuckle clockwise on the end of the threaded WGA arm till you reach your desired boost level.

It is Manie from Florida.
I was one of the first to pioneer the 20G-LT 'aka old FPGreen' if you remember.
The turbo is capable of 34 plus psi with no problem.
It is a good turbo.
You know I sold it to Felix in PR a few years back, and he is still using it and having a blast with it.
Dawm thing refuses to fail,

Hi Manie! Que Pepsis? Yes I remember you and your OS Green. I put 50,000 miles on my OS Green and it never failed me either. The highest that I ever ran mine was 27 PSI because of lousy local fuel availability and my tuner never wanted to boost it above 25 PSI. BUT, at 27 psi mine was barely waking up on 91 octane plus a gallon of Xylene. So, I can just imagine what it would be like above 34ish. Take care

I love ebc's but from what I have seen, they can only double the wg pressure at best. From trial and error I have figured out the best way to get the most from them. Run a bigger hose from an intercooled source ie; 1/4" hose from IM> to the BCS. Then as thin as possible hose from BCS>WGA. It should help with stability and higher psi. If you need way more psi then you might need to try a "JoeyMod". Get a pack of springs from a parts store and rig one from the flapper arm on the WG to the WGA drum/diaphram thingie. Thats the only way I have seen 30+psi to redline on an internal gate with NO bleed down.

Yeah on an unported housing it is tough to see no drop. You really have to hog out the turbine discharge as well as the entrance to the wastegate bypass port to see an improvement. Otherwise you are always gonna see a drop in peak pressure.
