cool.......how about the torque?

Do you have a dyno chart?

myfc3srx7

yep i will get it on in the next couple of days

RETed

Stock turbo?

That's fricken huge!
24" x 18" x 2.75" approximate!


That's a lot of power for the boost.
I think the fricken large IC core is to blame for the boost drop.
Your AFR is kinda lean for the top end!

edit - I can't read

You guys in NZ don't use dynojets correct? What kind of dyno was this on?

myfc3srx7

yes stock turbo

the big ic is because i will be fitting a bigger turbo soon as well as microtec ltx8,bigger fuel pump and external wastegate.

do you think that is lean?rotarys thrive on afr of 12.2:1

it was on a dyno dynamics dynamometer

i will post the chart as soon as i can

what is your highest grade of petrol there? 98 octane?

ours is 93 so we need lower A/F's

Their 98 is RON our 93 is (MON+RON)/2. They are not much different.
