Just curious how much PSI people are pushing with the stock turbo and intercooler, but with other mods like TBE, intake, bov, etc

 

spiking to 24psi on 93octane with full bolt-ons.

 

22.8psi peak. Take a look at my sig.

 

i am doing 1.4 Bar = 20 PSI .. and mods in signature with 91 oct

 

23 psi peak with TBE and panel filter on 93 oct.

 

24 Peak W/ My Mods

 

i was @ 27psi w/meth then i swapped out injectors and fmic and now i spike to 34.5 and level off at 30 in 4th and 5th. cant get anymore than 26-27 out of 1-3rd gear. the 27 was with TBE, intake, 280 cams, b.c.,hks vta,stock fmic & turbo. no o2 housing or porting.

 

28-30 psi with alcohol and DLI.

 

24.5 psi peak and holding 23 ... stock cat and stock intake.

 

I'm running peak at 23 psi with BR Stage I upgrade. I was actually curious about what was a safe psi for my type of upgrades as well. This sheds some light on it.

 

All these threads are real confusing. Some guys list their boost levels as a "spike," which the car never even really uses, and some guys just list what the car holds after the spike. A spike only lasts for a second or so. I guess in the case of "Spike," I run 22.5 on 93.

 

24 psi with mods in my sig

 

23.5 psi peak measured with map sensor based boost gauge. Also car is tuned to run at this PSI without knock. TBE, Works drop in.

 

24 psi on 100 oct. with a tbe and mbc and tune

 

I think people say "spike" when they mean "peak". My boost peaks out just over 23 and tapers off to 19-20 by redline.

EDIT: and did I hear that right...34 psi on the STOCK TURBO?! If the stock unit can push that much air, what would you want an aftermarket for?
