Just fitted my autogauge stealth 2 boost gauge and went out to see how much more I could wring out of her as the timing was genourous and so was the injector timing on WOT.

Turns out either my new gauge is crap or the boost has been raised somehow as the gauge is showing it boosting at 12psi at WOT??

I couldnt see any boost jets when I took a peek and couldnt see any bleed valves.

Any Ideas??

HeHe

I want to let ryan take a gander at it first

If its running a true 12psi the injector timings are good and the ignition timing is good as well, im wondering if its chipped and I dont know it?

She isnt chipped bro, I can assure you there is no bleed valve fitted and no boost jets stuffed in her but she does have new turbo's fitted (as of 16 mths ago they were new anyway) this may have increased it a tad. Fooking quick car that for standard, often asked the question myself!

 

Still in mourning, Jase.

Hey jase

If there aint any jets in her did the new turbs have stronger wastegate springs fitted as the ecu should be controlling boost to 9psi? irrespective of there being new turbos on it.

I know what you are saying though about it being quick :-))

Yeah should be 9psi, cant honestly say........ The car is too quick to be standard but doesnt appear to have been modded, when I got her she still had the standard air filter etc (Still got it, I will bring it to a meet for you if you want it?) She once had a turbo timer but it kept playing up so it was ousted. I had two TT's at the same time and she was far quicker by a noticable amount. I just dont know......... I honestly believe that out of all the 1000's of cars built, one is just really special and this ones it. Anyone doubts it..... go out in her, the gear change is second to none and the drive is nothing short of perfect.

Havnt been in a standard z though gotta agree with jase on the performance of the car...might get more info on it when i go to ztechs check up day.

Mind you now i dont have to worry about things I will start saving for a full forged bottom end.

Think I will take a look at it next weekend.

I could be imagining things and the new boost gauge might be wrong as well.

It was that I couldnt find any boost jets and couldnt explain why it was hitting 12psi, its not hitting 12psi like a manual boost controller would either as it seems to be regulated ( not all or nothing as it builds nicely )

the standard gauge reads just a smidgeon under 7 on WOT.

But the new gauge is showing a difference in readings as soon as it starts , it even dissagrees on the negative side as well,Im gonna go away and do a thorough look at the boost pipes next week and the ecu....then give up and let ryan look at it...hehe

Its standard.

And quick too!

If you say its fast mate i will take your word for it as my experience of these is limited.

My interest was raised when the boost was higher than i expected it to be...im still plumping for a dodgy gauge ive bought but will find out when i pop up to Ztech

Ive just noticed on my 'standard' indiglo dial (in psi not mmg) that when i boot it, I'm apparently hitting 12 ish psi !!! :hyper: I'm not aware of any mods to the car, so am kind of in the same boat m8, let me know how the investigation goes so I can unfold the mystery under my bonnet too :rolleyes:

(had a rolling road sesh when i got it, and it came back at:

217.3hp @ 6000 rpm

210.3ft/lb @ 4750 rpm

267.3hp @ flywheel)

 

cheers in advance

 

Brett

 

 

 

p.s. WHAT EXACTLY do boost jets look/feel like? and where am I looking to find them? :confused:

sweet, cheers mate!

Is that ALLthey are?? surely that cant be right? I thought boost jets were extra fuel jets added to the intake side of the engine to increase fuel into the chambers??

(maybe I'm wrong) lol
