I hate cars :)

You have a torquey responsive >500whp pump gas GTR, even if there may be bugs to iron out it probably smashes most people here's pump gas cars in terms of all around power delivery even while hobbled. I'm playing a tiny little violin for you right now, thinking how little I'd complain if I had what you have right now :P

haha, do you think I would keep spending money on the heap of shit if it was not my baby :)

Thanks for your input. Hopefully when this is all over I will go over the thread and see how it matches up with the findings and hopefully a happy outcome .

Get a bigger Violin, I can't hear you :cheers:

What's controlling boost, Pete? The haltech or the boost controller? Maybe the boost controller is just being used as a digital display?

I do not know , the Boost controller is functioning but apart from that I would not have a clue , if it is just a display or controlling it. Mick ask me to have a look at something and I will do that tomorrow.

Only a week or so to go, so I guess I will find out soon enough ??

Still think it's excessive back pressure due to too small a exhaust housing

.....as asked 5 pages ago, have you had the back pressure tested, my car shares similar issues to this and I have huge back pressure.

Haha he has a smaller turbine with a smaller housing with a bigger engine being pumped up by a higher flowing compressor. It's gonna be awful if yours is bad :(

Yup, I would say so....mine's kinda nasty, iirc it's something like about 7psi

Is there a boost curve? I wouldn't be surprised if the tuner has tapered the boost to try and get around it.

I would like to hear why people think it's excessive manifold pressure that is causing the boost to taper off 5-6psi

I know this is wrong but would like to hear why you think this, exhaust back pressure can cause this but not manifold presure

Either the boost controller is set to do this or the compressor is running out of puff, I would have said exhaust back pressure as a cause but the dum pipe and cat change made little to no difference

HI Chris, how have you been.

I cannot answer anything, I asked, gave up :(

But moving on and will wait for tests to be done and maybe I can answer the question..

I doubt if there is too much wrong and will be sorted for once and all :)

It's a possible explanation, not "oh this is it, case closed." Not everyone is arrogant or ignorant enough to say stuff to the effect of "I don't know what your reasoning is, but I know it's wrong."

I'm not going to explain the reasoning as I'm well past getting trapped throwing pearls before swine, I've just taken an interest here as I've been hearing quite a bit from people about this thread and keen to see a good outcome.

Why is it a possible explanation?

What is the thinking as to why this is a possible explanation ?

I never said case closed or I don't know the reasoning, I asked what the thinking behind it was from other people

But hey thanks for reminding me why I have been avoiding posting in SAU lately

interesting what the turbo does on an evo, although yours is a 0.84 split?? so it has a 62mm turbine??

Exactly what I was thinking. I'm not explaining to you because it has already been explained in here and because you've made it clear you disagree regardless... why would I?

Was good to dip the toes in the water again and see this attitude is still strong here, I hope this works out well - Pete... I hope things clear up for you soon, I'm sure Paul etc will keep me up to date :)

I just hope this thread stops...

perhaps even on page 69 for the humour

LOL 69 , always liked that #

I have said it before, it is easy to close threads, don't read them and even if they do not close, you will not have to read the shit :)

You say the same thing every couple of months, see you soon.

Just read the last 20 pages. A lot of people have thrown different theories around with explanations. Maybe they are right or wrong, but the discussions have been enjoyable and valuable I recon, even if we are all wrong.

    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
