S5 boost amount?
just was wondering if any body knows how much boost a stock S5 turbo motor can handle and also how much boost the S5 turbo will put out. I would love to know what people are running for boost on there stock engines.

stock boost is 8psi. with everything else stock I wouldn't go over 8. get a downpipe and a bigger fuel pump and you can run 10 or so.
after you get more fuel mods and a FMIC there is no point taking the stock turbo past 14psi or so. time for a bigger one. |
What about just upgrading your turbo to go over 14psi? Or do you have to get a new turbo?
|
i've got my t3/t4 with fmic and modified ecu running 15psi.

I'm running 9psi right now with no boost controller, I have full exhaust, intake, and chipped ecu. I know it's running rich, I'm installing a air/fuel gauge today, I have an apex afc that I will try to half ass tune it with now that I have the guage. I just don't want it running so rich because I'm getting really crapy gas mileage, and when I say crapy I mean like below 10. my real question is how much boost will the engine handle with this set up you think, I also have a 3rd gen fuel pump I could install but with the chipped ecu I don't know if I need to do that.
