Educated Guess At The Final Tune Results

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

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

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:

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 ??

I was just interested to know if the boost curve was deliberate or not, yeah don't get tempted to adjust anything, bit risky I learnt the hard way with mine.. :wacko:

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

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.

    • What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
    • Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.
