Rusty's GUIV-Upgrade

[rusty_nail]

Wow, lucky find, that could have been a lot worse.

Clean the MAF sensor yourself, if you're not sure on it, I'm happy to meet up and show you, it's really very simple to do.

Hey buddy I should be picking it up this week, if I do would you like to catch up for a beer and a hello? Would be nice to meet someone else from round here

No problems. PM sent

Hey all just got my nads fitted. Now I have the gauge and all fitted what Figures should I be looking at? It's peak boost is 21psi and highest egt I have seen so far it's 524°c. Because it's auto it doesn't hold the bossy when I back off but cruising at 110kph boost is anywhere between 5-10 psi and egt at around 350°c but goes into the 400s and 500s when it's revving high. Are these figures OK?

Bump for this one.

If your getting 21psi max I would go slighty higher in mid range boost. I.E 100ks to about 14 or 15psi. You might find your egts will drop a bit more. To raise your mid range boost wind the needle valve in a little.
500c is close to top end of the egt scale in my opinion.

WOW ,you reckon 14-15 psi @ 100kph, to me that's a lot of pressure for a long time
Seems a tad high I followed Chaz Yellowfoots lead and went for 10PSI at 100kph
My max is about 20PSI, egt's climb when pushed hard as to be expected and around
300-350c solo on the hwy

Thanks mate it does go up to that boost but it is sooo hard to tell what is normal because of the auto and it letting go of the boost as soon as you back off. I guess I'm not used to diesel and turbo and auto etc yet.

If I run 10psi the car runs like a bag of poo. Been at 15 for nearly a year, even towed my camper on numerous times at this pressure with no issues. I think it's all relative to the max boost. You run 15psi max, you go 10 at 100ks. You run 20, go higher mid range boost.

Right, i know some of you already know somehitng has happened to my car a few weeks ago, and some may not.

Bit of background first. I got NADS fitted to the car just under a month ago. I picked the car up from the mechanic just on or around the 26th/27th June. Drove the car around for a week and it drove fine. I was planning on going on a camping trip on the weekend of the 4th July. I was not even 5 minutes into this trip and lost all power on a steep hill ascent. White smoke poured out of the engine bay and i did not have time to see if it also came out of the exhaust pipe as i was on a main highway and in an extremely dangerous position as there was no where to pull over. long story short the car was towed back to the mechanic who had done all the NADS to tell me what the F%^& had happened to my car.

I have just spoken to him today and he is under the impression one of the valves has disintegrated. He told me there is little or no compression (cant remember which) in cylinder no 3. His diagnosis hasnt been fully completed but he believes this problem to be a head related issue and i will probably not be up for sourcing a new motor.

With all that in mind i thought i would make a post about it to get some other opinions. i know i havent been terribly detailed with my post, but its hard to know what to include and what not to. if i havent been detailed enough with somthing ask me ill answer it to to best of my ability, but yeah any ideas on what caused this etc would be much appreciated guys.

cheers

Rusty

also, special thanks must goto BA, MudrunnerTD and Mudski for the text messages of concern/interest in helping me in what ever way they can manage, i really cant thank you enough guys.

[MudRunnerTD]

Damn damn damn damn damn.......... Head is better than an engine! Is a disintegrating Valve a common problem guys?? WTF? Is there a chance it might have gone in and caused problems? I have no idea?

Good luck with it Nic, Shattered for you mate!
