They lock them so no one can see their tunes, they did the same thing to my FC and Scott was able to get around it I would have expected more down low then that, you need to get someone else to tune

If it's the turbo selection that is causing these issues.... Everything else is irrelevant. See what the new tuner says.

You're dreaming its not out of puff & i don't know how you're jumping to that conclusion?! As history repeats you can bet these blokes haven't done their job properly AGAIN! Odds are the boost control hasn't been played with properly or they have piss weak springs in the wastegates. But falling on its ass like that at 5500 isn't showing the 6262 being all in IMO pretty sure itd taper off more gradually then just drop off the planet like that. It is a 705hp turbo FFS and hes using over 500 of it currently.

Thats your conclusion.

While I don't think that turbo is necessarily the best option for this setup, I tend to agree that the turbo is not the most likely cause of what is being seen. Again a shame that there appears to not be better communication from the previous tuner.

how does it go starting at low temp?

Is that not the reason xklaba didn't take his?

Never had an issue. Even down at Cootamunda in the middle of winter, left outside at the hotel. That was bloody cold that morning too.

Get the tuner to do a PROPER cold start.

The problem I have is my car was tuned to in summer where the mournings are still over 15deg so setting it up for 0 deg is a guess at best, it starts 6 deg with a bit of whinding, less then 10 seconds

It just wasn't looking like starting and at 5:30am with my fuel pump I didn't want to sit there whinding for however long it would have taking to start upsetting my already dickhead neighbours

I also have cold Denso race plugs which wouldn't cold starts

Maybe, would be pretty disappointed if the workshop didn't sort that out.

And boost can drop like that if the the rear is beyond its VE especially if manifold pressures were to rise and this would obviously crack open the gate amongst other things. I still think the .82/62 rear is way too small for a 3.2.

Pete, seriously....Don't worry about all this response rubbish, just go and buy yourself a GT42 and be done with it. Rev the f@$king thing past 3000 and be happy with the face stretch when it comes on. Been done hundreds of times before and it just works.

Fair enough.

Now, I need availability near my work or home.....

or, stick with 98.

I know what you mean, I would have to drive about 200Klm to get it and it would be just about 3/4 empty when I got home.

Different deal if you are doing something special with it, fill a few cans. Thats were the flex fuel sensor will come in, use it when it suites you :yes:

No worries mate, all good.

Had a 80klm drive this morning to get the cobwebs out, good stuff!

Take car to Jez

End thread

Yep well this thread will only ever be more supposition until the car goes to another dyno to find out what is really going on. At least if it goes to DVS Performance he can read some of the history behind it here.

SORRY, it cannot be over until the " Final Tune " after this 3.2 build is finished, so hopefully, very soon :)

Probably will not be too much KW difference but might change were it starts kicking in ?

Never heard of an external wastegate opening due to exhaust pressure tbh, I'd consider it a design issue if it did - by function definition they are meant to block any flow until the reference pressures met targets - especially if it had both ports utilised.

In regards to VE dropping, that's just going to mean boost pressure will go up for a given airflow - the 62mm hot side is proven to flow much much more than Pete's setup is asking of it... so while I agree it's hotside is way too small for that setup (.8x twin scroll 62mm on a 3.2 - what the actual f**k? I didn't realise...) IMHO I think that explanation doesn't add up. In saying that, it's making good power and if Pete is happy with it then really all that really seems to be needed is making sure the mechanical and tune situation is on point and enjoy.

Things don't seem to be necessarily optimal, but I'm not expecting to see miraculous improvements in power - perhaps some improvement in power delivery if it turns out the intake cam proves to be excessively retarded in practice.

      Pillowball/Hardened Runner Hybrid Approach

      By TmZer0 · Posted

      Suspension Component Question Looking for some feedback based on people's experiences! I know this has been loosely covered in other threads but I can't find any direct answers/experience. I'm up for some bush/rod replacements and was interested in a hybrid approach between hardened rubber and pillowball kit. Why not choose one or the other? Well, this is for my daily driver, which I track once or twice a year. I like a stiff car and a sporty feel but I don't want to compromise the chassis too much with 100% pillowball gadgetry.  I know from experience and a tonne of reading that not all components affect ride quality in the same way - eg. in my case, coilover top mounts should be hardened rubber as pillowball transfers way too many undesirable qualities and doesn't have much more upside than a good hardened rubber. But, pillowball tension rods translate to much better turn-in/steering response and make the car significantly sharper, without negatively impacting ride quality in a significant way.  I'm not TOO bothered by NVH (to a degree). So, with context out of the way, does anyone have any experience with a hybrid approach as mentioned above? I'm going to replace all components over time so am seeking guidance on: - front tension rods - upper camber arms - rear lower control arm - rear traction rod - rear upper camber arm Secondly, is there any reason why this is a bad idea? Or any other info/wisdom that I might not be considering. Cheers 🫶

      Misfire/stalling issues

      That's good to hear I'll stick with the stock I hear they are good for 500hp and I'm only shooting for 350-400 once I can get this thing sorted and get to actually building it.

      The stock one will outperform any aftermarket standard position exhaust manifold. If you don't believe me, do a back to back test (same turbo, same boost, same timing) and you'll be super surprised.

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      Any recommendations on a decent replacement manifold that doesnt break the bank or require additional mods for the stock turbo setup? I figure if I'm going to pull the manifold off anyway to fix the studs might as well replace it.

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      So I checked the turbo out today. Very minimum play at all just enough for the oil to take up when it's running. I did find an exhaust leak at the manifold. 1 stud all the way in the front is missing and the one all the way in the back is broken off. Front has visible signs of an exhaust leak. I'll fix that soon but that's not my problem still.  I also found that the nipple coming off the turbo had the hose capped off and a hose ran from the j-pipe by the bov going to the wastegate. I removed that hose and capped that nipple and put the turbo nipple hose back on the wastegate.  There was a ton of oil residue all through the charge side of the intercooler piping going to the throttle bodg. I'm thinking that's from the pcv. Doesn't seem to be coming from the turbo that was all clean on the pipes side.  Haven't had a chance to check fuel pressure yet, haven't had time been having to pull a lot of doubles at work. I did pick up some carb cleaner to clean the iacv but wanted to make sure I had a fresh gasket in case the old one rips when I pull it off.  I'm waiting on a MAF that was supposed to be here today but delayed to Monday. Have a double Monday and Friday and work all of next weekend so going to try to find some time in the middle of the week to try that out. Did about a 10m trip around the block today and towards the end the issues were coming back. Fingers crossed on this MAF but if not just going to throw a fuel pressure gauge in and see where I'm at.  Did notice today that I can definitely hear the injectors pulsing. Very audible clicking coming from them. Assuming that's normal? Should also mean CAS is functioning somewhat properly. After it warmed up when I started it the intermittent misfires came in again. Did start doing that before it was fully warmed up.
