[Mk2] [Turbo] pulling 309hp can I up the boost?

[phillips1981]

after my turbo broke i fitted a new turbo tec unit with slightly better bearings and shaft but basically their standard job. i also stuck the rogue rev 6 charge cooler, berk decat, rev 6 zorst and cooler grade plugs (hks filter already on)

its a rev3. using 5,40 fully synthetic oil and some better gear box oil (not sure its relevant)

I bought a boost controller along with the supporting mods with a plan to up it to 1.2bar but not fitted it yet i just needed an mot fast. after plumbing the turbo wrong the garage i went to used the dyno to see was was going on and when they plumbed it right we gave it a run out of curiosity

309.2 HP I was obviously over the moon but thats without the boost controller (265whp)

my question is will i still be OK upping it to 1.2 bar or is it already running as much hp as you'd say to go with without going down the forged route?

seems a shame to not fit it but i don't want it to go pop.

I've upload the graph i dont understand much past the hp and tq. it may have the boost on it

cheers for your help guys

I'd just leave it mate as the standard injectors run out around 320bhp.

The ebc will bring the boost quicker and control boost better so I'd still get that fitted and then just enjoy battering M3's

how do you know your not already running 1.2bar?

do you know what boost its running at present? i wouldnt be suprised with those mods if it isnt creeping to 1.2bar anyway.
those are the sorts of numbers 1.2bar brings give or take.

[phillips1981]

the dyno bloke said it was at 1 bar. before the run it was over boosting to fuel cut. 1.25 1.3 so we were looking at the boost when he plumbed it in right. injectors can only push 320? what happens when the injectors max out?

mixture goes lean, pistons go pop.

I got 302 a couple of years ago with the same mods but knackered ignition components (didn't know at the time) so I would say you're probably at the limit without sorting out the fueling.
