Can I run 15psi?

[TalonBoy90TSI]

Ive got a 1990 TSi FWD and the mods i have so far is a o2 dump housing, test pipe, dejon intake, k/n filter, and the free mods. I kno I need a boost gauge but can i run 15 psi safely with the mods i have right now? Also which is a good cheap mbc, maybe around $80-100..

I recommend www.boostcontrollers.com
They sell the Joe P for like $40 plus the Hallman series.

I picked up the Hallman Pro for $100 about 6 months ago and it's perfect. Boost level never changes and when I installed it, the turbo spooled faster.

Just my .02

Oh yeah, sorry. You should be able to run 15 psi with no worries. I run 16 psi on my T-25. Just make sure you get a gauge first before you start messing with boost levels.

Would it still be safe even though i dont have exhaust?

And when i mean exhaust, i mean i have the stock exhaust just no cat..

Yes it is safe, I run 15 PSI on my stock 14b turbo, I have a autometer boost guage, a 3 inch intake, and a homeade boost controller, the only time I have problems is on cool evenings when the boost may spike to 16 or 17 psi due to air density. Buy a boost guage, and turn it up, My buddy paid 68 bucks shipped for his Turbos XS MBC, it works very well also. Though I paid about 6 bucks to make mine

Your car should definitely be to handle 15 psi day in and day out, but before you turn up the boost, make sure you get a boost gauge. There are SO MANY horror stories out there about people accidentally running 39 psi without even knowing it (and consequently destroying their engine).

39 psi! Damn what turbo does that? No 14b or T25 could even come close!

 

[sonicnofadz]

hehehe, I was just exagerating to emphasize the importance of a boost gauge. In reality if you overshoot your boost using a 14b, you'll probably be looking at around 20-25 psi maximum output, which is still enough to destroy an unprepared engine (especially with no race gas). There are large ball bearing turbos that can go well and beyond 39 psi.

They DO make a 60 psi boost gauge... so... who wants to claim they got their 14b to 60psi? jp
