Andrew from AM Performance ran his car on the same dyno at Jason, and made 308rwkw, then went down the road to the Willall mainline and made 249rwkw. just to give you an idea of the difference

at the end of the day its for tuning, not for bragging

tis annoying how some dynapack owners dont calibrate it properly though.

trent runs the same dyno and has his reading within a few kw of a dd for when he does printouts.

makes a lot more sense for comparisons

How is reading DD like dynos "properly" calibrated?

What he means is that most dynapack dynos read significantly higher than a DD dyno in the norm and trents one pretty much is spot on with other DD ones which arent happy so it makes for a better comparison with other peoples results.

There are 4 calibrations for different regions (like usa which use old std) and test procedures:

SAE

DIN

and two others i cant think off.. lol (as i never change it)

some of the operators in sa seem to always run theirs in the old standard which inflates power... have bought this up a few times with them as they give the dyno a bad name even though its actually far more accurate.... hell i could have got a 4wd roller for the price of my new 2wd dynapack...

on top of every dyno sheet from dynapack is the correction type used, if it isnt in SAE J1349 (2004) ask it to be changed. Also like any dyno make sure the Air intake temp probe is set to ambient and is reading real ambient temperature

Almost a direct overlay of my T67 set up on the same type on dyno with the same correction... Actually uncanny!

Which begs the question, how much boost?

Yellow run was 17.10psi

Green run was 18.36psi

Is there SAE J1349 a separate setting to SAE? I always have used SAE... and "inflates power" is surely a relative term, regardless. So long as all details are considered it is what it is, I'd call it more "inflated" where people reduce smoothing in the hope spikes will boost the #s.

Unopened rb25

Gt3076. 82 IW

Caltex eflex

310rwkw 16psi

320rwkw 18psi

Leak in cooler piping/plenum that needs to be fixed then its back for a tune as it wont hold more than 16 psi and sounds like I got a midget under the bonnet blowing a trumpet lol

Damn that lil midget bastard gets around! he was under my bonnet too lol

and the funny thing? both are mainlines.

use this formula:

mods: PowerFC, GT3037 Garret, 0.6 cpm Cover, 0.63 rear housing, 18psi, Nismo 555s, 3inch turbo back exhaust, 600x300x75mm intercooler, Split Fires, NGK BKR7E plugs, Water Methanol injection, 275ml min nozzle.

fuel: Shell 98

power: 320rwkw, 720nm Torque @ 3200rpm

oil: Shell Helix 5w40 fully synthetic

useage: Every day

lifespan: Lasted 4 years, until I decided to upgrade to RB2530. Engine was still 100% compression wise when sold. 165psi accross all 6 cylinders.

failure: none

comments: Was an awesome car to drive. I did all the tuning myself.

    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
