rb25det specs

[kylekinnamon1989]

i know the rb25det has 250hp stock and 213 torque, but how much boost is that set at and what could i set the boost at to get more hp but without messing it up? thanks

7psi factory, less if using the boost solanoid.

14PSI is the rumored and tested threshold.

Factory RB25 turbos have blown apart at all pressure levels up to that even at 7psi factory specs.

Cermanic wheel = faiL

thanks coolwhip.. ur a good help lol... seriously tho

while were on factory ish like specs, anyone know when the turbine spools rpm wise on a stock RB25?

[BoostFab]

the turbine spools at 800rpm

stock is set at .46 bar~6.6702 psi.

i've been running .85 bar ~ 12.325 psi, for over a year with no problems, using an apexi safc, and avcr.

with no tune i made 220whp and 217 tq on a dyno dynamics dyno, which is notorious for giving out lower(realistic) numbers.

you made 220whp on 12lbs?

[coreansurfer]

yea, i was actually a bit disappointed because i could have made more power with a tune, but oh well, that will come around soon.

stock rb25 block and turbo w/greddy intake, greddy vspec fmic, q45 tb, z32tt fuel pump, apexi gt spec(95mm w/115mm tip)apexi safc and avcr.

next on the list is an HTA twin scroll gt35r, and supporting mods.

my old daily driver

all stock, just fmic and manual boost controller set to 10psi

[coreansurfer]

keep in mind that those numbers are on a dynojet which gives inflated numbers.

Inflated by what percentage? (estimate)

[coreansurfer]

a dyno dynamics reads approx 17-20% lower than a dyno jet.

[240z4u]

a dyno dynamics reads approx 17-20% lower than a dyno jet.

Depending on calibration...

All around, I do agree though.

still 220whp @ 12psi with a rb25det seems really low

[ANVIL]

my rb25det dyno'd 220 last year with everything stock except for fmic, fpr, walbro 255, 3" downpipe/piping to n1 muffler.

that was with a broken boost soleniod, so im not sure how much psi that was.

within the next week im getting on the dyno for a full tune @12psi from my ebc, with power fc/datalogit probablly 3 different maps too (race gas, torco, and pump)

not sure what what to expect... but im hoping at least 250. what do u guys think im going ot get?

im trying to go for high 12 1/4 mile or a 110ish trap. i ran it at the track with the fc untuned and only got 14.1@100 (my ****ty 2.1 60' doesnt help). i found out later that the fc map i was using is set at 7.4:1 AFR @WOT.. wtf!

tires, suspension, drivetrain... yeilds best times when improving times.

[mattleegee]

You where on the dyno with a stock fuel pump? I thought that was a must have before even starting up the first timeI dunno 220whp just sounds more like a rb20 or sr motor for some reason even in total stock form

tires, suspension, drivetrain... yeilds best times when improving times.

you forgot driver in that also
