I can understand the need for an accurate inlet temp sensor. After my upgrade I was horified to see that my inlet temps (showing on the PFC) were consistantly around 25C higher than ambient (50C on a 25C day). What I did notice, however, is that the IC outlet was cold/ambient to touch and that the inlet temperature readings on the PFC hardly varied.

In reality I suspect that what I'm really measuring is the temperature of the plenum wall (nicely heated by the engine radiant heat) rather than the intercooled air passing throuh it.

Where do you place the aftermarket inlet temp probe?

Between the plenumn and the pipe that feeds from the inner guard. I set it up so the tip is in the centre of the pipe and does not come into contact with the pipe wall or plenumn wall. Ive always had the thought that the std probe is affected by heat soak.

OK people.....its time to guess what power its going to make....

only changes are HKS 2530's > HKS GT-RS and a HKS ignition amplifier.

it made 443 AWKW previous on this same dyno.

I'm going to go out on a limb here and say.... it will be MORE than 443AWKW! :thumbsup:

..actually I'll be very interested to hear how much difference there is in lag Paul. I know this won't be too much of an issue for you since you're primarily drag racing.

I am having a RB26/30 built and have been told the 2530's might be a bit small, and to go for the GT-RS. In fact, they say that the 2530's would "limit me" to about 600hp. But with 443awkw, it sounds like you are proving the 2530's can go more. A lot more.. wouldn't that be around 700 flywheel hp or more?

Hmm my guess is 485 awkw :unsure:

so how's it going??? :rofl: hopefully ~500kw+

the JD's going down nicely thanks :P

unfortunately no news yet.......(no news is always good news with CRD). It's hard to be so far away. I wish I was there. I hope nothing goes wrong. I feel like I'm waiting for a baby to be born. :D

STACE

I think ONE of the users logged on right now might win the guessing comp!

Was that me? If so :D

After the 443 4wkw with 2530s' I am not so sure I can guess it.

The race brew makes the numbers somewhat unpredictable.

The raw maths say 550 4wkw.

So I will throw that in as my best guess.

Good luck guys, we have a Friday drinks rule

One JD for every 100 horsepower

So you better get started.

:P cheers :rofl:

PS; the boys get all excited when we stick a blown 7 litre on the dyno, it means plenty of beers for them

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • 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.
