K24-7400 boost profile on stock I5

[prj]

Good to know you had time to map it.My client will be happy to know that.In aprox 1 month or so i will get his engine ready and will need soft.Will pm.
He will be sad knowing that it will be less strong compared to 7200.Or i will keep his setup for my rally project b2 and fit him a holset/k26 setup of yours.Do you still can provide that?
What about smaller shaft diam. compared to 7200?Will it hold?

Whether the turbo survives long term or not, time will tell, but it's a KKK
For rest, yes PM.

Out of interest, what is an RS2 turbo actually capable of bhp/nm wise? Always thought that realisticly an RS2 turbo could make maybe 360bhp/around 500nm?

the RS2 turbo can do more ~380-390 but not with RS2 injectors as they do not flow enough.

About 375/590, but not on stock (RS2) injectors.

That sounds like a really nice B-road weapon.

Had a chance to tune this turbo finally.
Bought one off of Ruffiano years ago, never got around to fitting it.
So it collected dust in my cellar, but finally found it's way onto a I5.

Full boost is at 2600-2700 rpm. Basically it spools better than stock.
The boost profile is:
1.7 bar from 2500 to 5500 rpm, after which it tapers off to 1.3 bar at redline.
The turbo can not do more than 1.7 bar at 5500 rpm and then 1.3 bar at 7000 rpm (98% N75 duty cycle with 1.9 bar spring) and IAT's start to go up.

So it is not as strong as a RS2 turbo - that can do 1.45-1.5 bar at 7000 rpm, but it also has no lag at all. Instant 1.7 bar all the time with a 3000 rpm power band.
It makes about 540nm and 350 bhp.
