These results give me a little tingly feeling in my balls thinking what the -5's will be like on my 30/26. Obviously provided it's setup as brilliantly well as yours is.

Hats off to you for your perseverance with it! Now the fun begins (driving it!).

Enjoy!

Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

I think you need a 4wd dyno to do the final power output.

Do you know how much timing your running?? not sure if you know, when running tight squish you dont need the timing and if you put timing in it does not like it and what AFR is the tune to under full load?

I can't answer that Bobby. I will find out specifics later on as the tune is not finished. it only had 9 runs or so. I dare say the AFR's will be a little richer then what you like ;)

As for 4WD dyno. Wanna spot me a run up on yours? :P

Was lucky enough to take a mates 26/30 for a belt in Melbourne with dash 5's built by rp

300rwkw at 3000rpm

You will love it

A fair bit of thought went into it all. I think the interesting thing is the cam duration. They are not massive lumpy grumpy things!

Having seen a sorted 30 with 5's on the same dyno.... providing it's sorted, you're in for something special ;)

What is the deficit going from rwkw to awkw in your experience Bobby?

300rwkw at 1400rpm less than Paul's is insane!!!

Didn't your mate Deimar do a test at CRD one day and there was 2 KW in it?

that member repetition looks to be a virus - i saw the same thing a few pages back.

sorry paul, ive even tried to edit my post & the site wont accept which is odd.

were your cams dialed in?

Zero zero... We only did 9 runs from a totally new ECU and that's what it spat out.

They will have a tickle this week to see what it does. If it takes away from the midrange I don't want it!

I mean when the motor was build! since the cams are custom, its why i asked if cams have been dialed in to find zero? if not, i think its a good idea to know where the cams should be before playing with them

We know where they are at zero zero. Yavuz set the loves up where he thinks they should be.... Not to say a degree here or there might make the difference.

Lets see what next week brings ;)

Geeeez looks like that port work on the head is doing the trick...

Who would have thought HKS knew what they were doing :/

But did they? its had the super special cams and springs changed in....

Edit: of course they know, but is it better than something that could of been done locally, as yavuz deemed it necessary to make these changes

Its hard to quantify any gains from port work without doing back to back tests. You really need to do a stock head with all the same bolt ons. Then try a worked head with all the same bits and compare results. However, not many people actually have the time or money to try that exactly.

Everyone gets tempted by changes when they have the engine apart lol.

Well nothing changed apart from the head, cams and an extra 0.5mm on the pistons. ECU did but meh

      New fix for low tyre pressure from bmw

      By MBS206 · Posted

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.

      You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
