Wat is a safe boost level for my sti v6

[boon]

Pretty sure the standard ECU will fuel cut hideously at anything much over 18psi.

[G-unit]

if 18psi isnt enough then try 22psi, then after its blown something remind yourself that 18psi was dam quick for a stock set-up

[Stoffa]

afaik fuel cuts not till about 25psi on v5

[Razzmatazz]

Lol hahaha it was just a test ur right tho feels like a different car on 18psi for stock I'm not going to go anymore then that not withit mods

I don't think the center dash is the same as v4 had no clock or gauges just a lid ???

I'll try find it and get a picture, v4's have no gauges etc stock this one is an aftermarket lid. I'd planned on buying a V4 so I got it but didn't end up with enough money from the Pulsar so it's useless to me now lol

[Razzmatazz]

Sweet man send me a pick how much u want for it?

[Stoffa]

v4,5,6 all have the same dash, v3 and earlier dont have any top box

[Razzmatazz]

Sweet well if that's the case how much man?

I wouldn't go above 18 psi I have the same car pretty much and mine was modded all,supporting mods and was at 20 psi an went bang, rod throug side of the block. Leave it at 18 it's a lot safer.

I approve of this post

[Razzmatazz]

I am leaving it at that lol I'm not gonna crank it all the way up to 20psi + on stockers thts stupid

[G-unit]

and not when u fit a "poddy" haha

Pod filter on newer cars = decrease in power if standard...

[Razzmatazz]

I've read a lot about pod filters? Stock is best from what Im trying to achieve

my v3 sti ecu (6s) would cut at 22psi

mine ran 20psi daily and loooooved it - walbro is key me reckons

aeromotive stealth is the new black now buddy

[WRXONP]

lol i ment in general a fuel pump upgrade more than anything else - a mates v6 sti goes pretty lean at 16psi where as another with a walbro stays alot richer

Were you also running split fuel rails?

[WRXONP]

nah stock rails stock regulator - walbro intank pump

spark plugs never shown any signs of leaning out on number 3 either

So with a fuel pump upgrade you're saying it's much safer to push the boost?

I'm thinking about getting a dyno run done in the near future to see what my afr's are like, would be happy to post results if they'd be relevant

[WRXONP]

6s ecu (assuming this is what u have) has a really good fuel map

i would never push any higher boost without a walbro (or similar) - hell i wouldnt actually even want to boost stock pressure without a fuel pump upgrade

im not saying its safe - alot of different factors can make AFR swing - especially ECT sensor and maf

[reaperblitz]

Sell or send me the gauge holder and il either try fix it or create moulds from it lol

[Razzmatazz]

I'm trying to get my hands on a walbro fuel pump, and yes post up results roo

seemingly the one serious thread (potentially relevant).

User has been asked to tone it down and the sillier threads have been removed.

Trolls and dolphins need no longer apply.

I dont see the difference a larger fuel pump would make on a stock setup?

Flow rate yes but the cars only going to be able to burn as much fuel as the ecu allows it. Its not going to know it has a higher flow pump?

Plus the fact the afm will only see the same amount of air coming in so i presume it matches fuel with that air as loaded in the factory tune no matter how much flow there is?
