made 400.6hp atrw today on 15 close to 16psi 47deg!!!!!!!

tryed 18psi coils were breaking down.... time for spit fires.....

also was close to running out of fuel up top with a sard intank pump and 720cc sard inj....

so were going to rewire the fuel pump with bigger wires and put in a relay

also thinking about a fuel reg? or should the stock one be fine?

still makes power at 8500rpm stock cams!!

yeah that will be the problem do you have a link for the fI guild mate?

ill also change the fuel filter.... still has enough fuel now, but there was no room for more fuel up top as it was starting to run out....

but dose it pull hard up top end!!!! power never drops off just picks up more and more :thumbsup:

still comes on around 4700 5 but makes up for it up top and the extra revs!

more boost will be crazy!

and down low its still just as nice to drive say 4000rpm under..... tuned helped alot still makes boost at say 3000rpm few psi so its not like a lag no bottom end power car! :P

FI Guide - is the stick topic @ the top of this section... along with the dyno result ones mate :P

Tells you what to do, its fairly straight forward and even i would be confident doing it as the DIY is very good.

I think there is also another DIY thread (in the DIY section) on top of the FI Guide DIY link :thumbsup:

In those kind of ambient temps your fuel temps may well have been over 65 degs on the dyno - which can cause the fuel pump to drop pressure and or flow.

I commonly see this issue on queensland dynos where the room temps are up around 40degs. Its just those bloody southern tuners dont have a clue how much difference ambient temps makes to eninge tuning!!!

I flew to Mt ISA to tune a GTR and i can tell you it is an eye opener....

yeah still in the process

im pulling the emanage out and have got Nistune installed now

things move pretty slow up here didnt you see that lol

are you saying the ambient temps made a huge difference Trent or not alot ???

Ive always thought that they would make an extreme difference to tuning

i did power runs on a differnt dyno it made 285rwkw on 16psi

coil packs are in re wired the pump

with the stock reg it was really rich after the wires were done!

fitted a adj fuel reg

turned it back a bit and added some more boost 17 psi same dyno as the 285kw run put out 336rwkw

300kw on 13 14psi

still needs a tune and more boost... will be done in a couple of weeks :D

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      Could it really happen......

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
