that 1k rpm difference shouldnt take that long right?

this might help:

turbo side:
port and polish the stock turbo
ball bearing journal
twin scroll turbo
downpipe (noticable different on response after i change to bigger downpipe)
Turbo side:
port and polish the stock turbo - this is to smoothen out airflow ?
ball bearing journal
twin scroll turbo
downpipe - > DONE, when converting into my E46, this one is larger like 3"

In between twin scroll vs ball bearing, which one can be much easier to be modified into CT15 stock turbo ?

PnP; yes, smoothen the airflow to promote better response. i did not do this because theres mix feedback on this. some say it works, other say better rebuild turbo or buy new one.

twin scroll require u to change exhaust side turbine/kacuk to other model. better off find good twin scroll turbo.

ball bearing would be easier to modified, change the internal stuff.

I better off going with ball bearing, because i am not planning to change the turbo as that will require me to change out the manifold as well. One mods lead to the other, after modifying the turbo, fuel injectors and ECU needs to be modified as well. Never ending journey,

upgrading to ball bearings is already a step in that direction

Cruising at the limited top speed of 250kmh for 20min will dry up the tank.
to cruise at that speed...titanium ball

good choice.

if you not going for high power, remain stock injector is good enough..just get it remap(if its possible for your stock ecu)

I am going for fast response, the power is there on every command, like a small turbo kind of response. Stock ECU as far as i know can't be remapped by many tuners. I will need at least an adequate piggyback to molest the stock ECU.

Forget piggybacks and get a decent Links ECU la. It's one of the better and cheaper ECUs right now and definitely has more range than a simple piggyback

I only need very simple AFR tuning due to my current intake and exhaust piping are non stock, so car is not running optimally. Link ECU might be overkill.

Bro... Don forget one fella have adamantium balls. lol...

I guess AMG assume by default all of the AMG owners have titanium balls hence it limited to 250kmh.

Those with adamantium can go ahead and remove the limiter and reach adamantiun level of 320kmh.

Anyway, i also want to know what is the fc for such powerful perdana. I bet it can beat my Pajero. A trip of about 90km (Mlk to Bahau) at speed of 80kmh and below will consume at least 1/4 tank...thats about RM50-60. Offroad? 20min or crawling palm oil plantation using 4x4 mode will consume 1/4 tank too.

Its 2 different world of motion but one thing in common....'excellent' fc.

if you think current ecu is not up to par with your expectation, better go link ecu.

from my POV, either rechip or standalone.link has good support and affordable.

but i sold mine and using rechip now funding for haltech elite :evil::evil:

that guy one second adamantium balls, another second saggy ball. hahaha

my car i only confidence up 180.

200 is my limit because the car felt 'light'
fuel consumption worse 8km/liter , chill drive( underboost) 10km/liter:driver::driver:

Your pajero is diesel or?

Petrol...all 2555cc of it.
Engine code 4G54.
90kmh at 3k rpm so u can imagine the fc.

Fastest i go is 140kmh at Lekas and its too much to take with the engine noise, wind noise, and body movement.

Thats about the same as my Pajero. Cool, we have something in common despite different speed...hahahah.

I think i can beat your chill drive figure if i dont use aircond on the Pajero. I still remember i got 11km/l driving like an old uncle and aircond Off plus upshift at 2k rpm.

Also, i notice that carrying more weight does not affect the fc. Putting the roof rack which messes with the wind will double fc. Is it the same with yr car? I think its down to the torque figure and availability range.

At the rate you're modifying your car - you might as well prepare for more with a full on standalone. Considering how it can do everything, it's not overkill. Just peace of mind.
