Projected Power --- Anyone

[ShiftyR31]

Hi guys i know theres no magical formula for this question to give me an exact figure but can someone help me out at what power this should product. Remember this is going in an R31.

* RB25DET

* Standard Turbo

* Wastegate (no bov at this stage)

* R33 Front Mount Kit with stainless steel piping

* Wolf V400 ECU

* Larger injectors and fuel pump

* RB25DET gearbox with twin plate clutch

* R33 Brake upgrade

* 1 piece tailshaft

* Custom diff

What i want answered is a few questions.

* What is the standard RB25DET turbo like ? How much boost can it handle ?

* Will the standard turbo be able to keep running on 1bar of boost safely and reliably

* What power should this package produce

turbo will die if run at 1bar for time. the safe level for them is anything under approx 12psi. if you were to run the car rich as hell it would prolong the life slightly as the exhaust temps would be a bit cooler. the main limit in your setup is the turbo. running it past 12psi is slightly pointess as they are out of their efficiency range.

also i would look at some kind of bov just to take a bit of pressure off the turbo. not 100% necessary, but a bit safer.

power wise you should be up around the 200kw-210kw. if you highflow the turbo then you can bump that power figure up a bit to about 220-230kw.

Well the stock turbo has a wastegate already, you dont really need to mention it, unless you'd changed it?

Your results will be the same as everyone else really.

180-200rwkw

If you used the search button you'd see that the stock turbo can let go at anything above 10psi. Its really luck of the draw.

Larger injectors are just a waste of money. You wont need them

[ShiftyR31]

So they stock turbo can shit itself at anything above 10psi. Hmmm any idea on what turbo i should run without changing the internals. Something that can run around 1 bar safely.

Why pick a boost level?

Have a read of the dyno sticky thread, any setup around 250rwkw will do you i think.

pick a power level, not so much a boost level. What do you want power wise then decide what you need to achieve this.

a big definate with the diff tuffened up if aussie 31, should be close to 200 kw hopefully! as said b4 larger injectors not needed yet put money towards a hi flow or another turbo!

Anywhere from 190rwkw to 210rwkw.

Hope you don't want to rev it. 99% of one piece tailshafts go critical after 6500rpm unless they have extra thick tubing.

Um wouldnt tailshaft speed be dependant on what speed you are doing not rpm? being as its after the gearbox.

[ShiftyR31]

well i was hoping on getting around 250kw out of the car. seems like this number is slowly getting out of my reach. With a larger turbo would this be obtainable. Sorry im a newb to the turbo scene. Ive had v8s in the past so excuse my ignorance to the issue.

[R31Nismoid]

You'll have to hi-flow it.

$2000, great value, awesome response. Cant go past it IMO.

Also, as i posted earlier... please read the sticky thread.

Nothing wrong with being new to the scene, but there is a lot that you can do to help yourself
