help with power output

[THE_REAL_SLYR33]

hi i have a series 1 r33 skyline 3 1/2 inch turbo back exhaust huge front mount intercooler malpassi fuel reg a walbro 550hp fuel pump and am about to put the power fc in and get it dynoed on 14psi what kind of rwkw would i be looking at

[Abo Bob]

You are going to run the stock turbo on 14psi why?

my guess is 195rwkw

[JaFF]

i thought stock turbos blewup anything over 12ish psi?

or can a series 1 turbo handle more boost than a series II?

[caminperth]

They'll all work at that boost.

For a while.....

[Frink]

i thought the stock turb's could only handle 10-11 psi?

[race_snooze]

This is an age old debet, my persnal experance is that i have ran my 95 r33 with remaped ECU (32), fmic, turbo back exst, HKS pod filter, bleed valve on 10, 12 and up to 14 all day every day for 2 years I normaly leave it at about 10 or 12, 14 when racing and had the dyno

run that other SAU's from canberra saw running on 12 well .7 bar, it always spikes to .9 bar then drops back. Stock turbo

[JaFF]

so 14psi would be ok in short bursts?

I live in tas and its pretty cold down here all the time. like 14degrees is a warm day! Would it be ok to run 14psi every once in a while?

thats the safest zone to run them in 10-12psi they will run 14psi some even higher but dont expect them to last

cubes ran his rb20 turbo at 16psi on his rb20 it still running 9psi on his rb30det even though its seriously restricting power on the big boy..lol

The real slyr33? phhh!!!

[R31Nismoid]

stock turbos generally wont give you an increase in power much at all over 10psi going to 12psi.

you might get a little... but its nothing worthwhile and only shortens the turbo life.

some people have freak turbos that seem to take it, but most dont

1 bar = 14.7 psi

0.9 bar = 13.2 psi

0.8 bar = 11.8 psi

0.7 bar = 10.3 psi

etc

I run the Stagea turbo at 0.7 bar, because we have killed (ceramic in the cat disease) 4 turbos at 12 psi on other Skylines. We found almost ZERO power increase running the standard turbo past 12 psi, they just heat up the air.

[THE_REAL_SLYR33]

hi guys just an update got it dynoed today very shit tuner sugest you dont ever go to incar performance at wethiril park sydney but still got decent power 234rwkw standard turbo standard injectors 14 psi for power run than to 12psi for street quite happy with the result but told by jem (just engine management) more could be done with the map and it was a shitty tune

post up the graph mate, let the masses decide
