Bringing back CP9A - 6RS Stock motor EF3

I'm a new member to EvoM but been on these forums a few times over the years.
Just thought I would share my Evo results.

I've had a few CP9A's here in New Zealand and to date is my 6RS with 325wkw on the rollers.
It has had the basics fitted including -
3" exhaust
Custom dump
Stainless manifold w/45mm runners (supposedly HKS)
MAP EF3 turbo 2011 version no anti surge.
Fuel is AEM 320lph, ID1000's, Sard FPR.
Custom intake w/air box, large Blitz intercooler and custom 2.5" piping.
Stock ECU with Evoscan to tune.

Motor is unopened including rocker cover, No cams installed yet. That will probably be the next mod including head studs.
The blue line on the graph is my best power I made with stock turbo TD05HRA 16g6 10.5T with factory 560cc injectors, but I wanted more haha so in went the EF3.


325wkw 1000nm in 4th gear. The graph shows 350kw as that was a one off power run to see what would happen with some advanced timing and a touch more boost. We both agreed it was unsafe as it did get a fair amount of knock so took back the timing and settled with what I have today, but I didn't get the print off of the 325 unfortunately.

Im still learning to drive with the increased power, my 60fts have suffered a bit from the lag increase with the EF3 and with no launch control it takes a bit of time to get used to.
However I have done a best ET of 11.94 with a 2.002 60ft at 121.35mph on street tyres. Quite shocking really but my goal was an 11.

Anyway I welcome all opinions on my build as it seems to draw a bit of controversy

Cheers!

Controversy? Are you referring to the torque reading??

Kw is usually the hot topic of debate.

Good, because there is no way you're making 1000nm with that turbo & motor lol

325kw (435hp) doesn't seem out of the norm for an EF3?

Any pics of the car? 6RS is a rare bird, very difficult to road register in AUS

Its 1000nm as multiplied through the gearbox etc in 4th gear. And comparing to other cars its a little on the low side. I dont know why its just how its read on that dyno.

As for power, the EF3 is not as responsive as it should be, even MAP dont get it but ah well.
It does flow a lot of air and has no issues with the boost. The drop is a problem with WG which is now sorted and dead stable.

Ill chuck one up
