look forward to the update when you tune it?

 

Once the ECU settles, I'll start playing with the vafc2. I haven't really gone that rich since the addition of headers. Still in the 12s. I know its not rich because its not regurgitating between shifts

 

Cattman is less than 2 1/4 collectors going to a 2.5".

I think it's 1 and 7/8s each bank and then going to a 2.5" OD collector (similar to my OBXs)

Dunno where you guys are getting these measurements from.

What you want is 2x 2.25" going to a 3", at the bare minimum.

The z crowd is running w/ dual 2.5"s going to 3.5"s, those seem to be the highest N/A cars.

 

 

That sounds siiiick! Added it to my fav max exhaust clips!

Can we get an update on how she feels wot as the rpms go up? I'm assuming the low end u lost will be made up top

 

Cattman Primary pipes: 1 1/2"
Cattman Primary Collectors: 2 1/4"
Cattman Secondary pipes: 2 1/4"
Cattman Ypipe collector: 2 1/2"
I'm not sure where you got your Measure Action Jackson......

 

12.5-12.8 is perfect for N/a!

 

When I drove this morning I got high 13 afr. That means my afr got leaner after installing headers. Added some fuel to the vafc2 this afternoon and its sitting high 12s then 13 to redline. I think my timing is now fubered from adding too much fuel, time for bigger fuel injectors than 350z's.

Edit: I need to check for air leaks...seems fishy to me

 

Going to some in cabin ones looking at the speedo.....

 

Is it reasonable to simply increase fuel pressure to 350Z/G35 pressure (3.5 bar)
