I've bunged some 1mm mig tips in today, till I get some extra pennies for en EBC, engine is recently rebuilt, perfect health, timing spot on, throttle balance etc. all hunky dory, no boost leaks (well, not since I last tested), runs sweet as a nut, but, after putting the jets in, feels a little bit quicker, not a right lot tho, ticks over a little slower, and my boost gauge reads exactly the same (9/9.5psi), jets installed correctly etc...

 

Any ideas?

 

Cheers, Tudor...

Shouldn't you be using 0.8s? For 14psi?

Maybe? I bought a couple of them too, so ill bung them in and see what happens...

Not tried the 0.8s yet, but after doing some reading, 1mm should be about right really, but I'm still getting 9.5psi according to my aftermarket boost gauge, any other thoughts?

you sure you have put them in the right pipes lol!!

Zedworld put 0.8s in mine to run 14ish psi along with one of their chips

I think so? Them 2 shiny metal silver ones under the back of the car? :lol:

 

Will turf some .8s in in a couple of hours and report back... Only after 14 psi ish.

 

Oh yeah, got a mines ecu and a receipt for fitting ecu and 1mms with the car but I changed all the pipes and wanted it stock after the rebuild...

Ok, the latest.... Put 0.8s in, no different, so decided to investigate, turns out on the passenger side, the pipe from the intake that should go to the solenoid, was going to the plenum, and the pipe that should go to the intake (the solenoid) was going to the recirc, so I swapped them round, all is plumbed in correctly now, still the same 9.5 psi. Don't understand it....

Any ideas?

boost leak

safe mode

plumbed wrong

Gonna check for boost leaks shortly, pretty confident there is none tho, also sure its not in safety boost, as is boosts constantly at 9'5 psi and no error codes, and have installed them correctly, but will triple check all pipes, and will simplify them further, but already has a very simplified pipe system, really got me scratching my head, I re-built the entire engine, fitting boost jets is easier than scratching my balls, but no joy! Cheers, will report back in a bit...

Could it be your waste gates opening prematurely due to lazy spring pressure?

May even be that one or both of them are not fully closing.

Sorted it, on my phone at the mo, will update tomorrow :)

come on then its tomorrow .... what was it

Well?

yea man...the suspense is killing me!

Right then, here ya go! My laptop has been at my Dad's since using conzult, and typing on my phone makes me angry...!

 

So, I put in 0.8mms, and no different, still 'apparently' boosting at 9.5psi, according to my gauge, so, I went over everything with a fine toothed comb, deleted every boost pipe that wasn't needed and blanked off obsolete stuff, so the vac/boost system is as simple as possible, then found that the hose going to my boost gauge had collapsed and flattened, so I replaced that too.

 

Went for a test drive, but still the same, so, I put her on conzult, again, and it came up dett. sensor, code 34, hmmmm, seemed to be very intermittently and occasionally dropping into a kind of saftey boost, but still hitting 9.5psi but no higher, hmmm, anyways, I found a couple of breaks in the dett. sensor loom, so I repaired it, popped down the road with 0.8s in, put my foot down in 1st, and basically didn't move, just span up and hit 20 psi (only for less than a second tho), so I turned around and came straight home, swapped them for 1mms, back out for a spin, hey presto, 15psi!

 

By this time it was getting towards the time I was lending her to my dad, so I only went round the block. He got a few hundred yards down the road, safety boost (although now showing 7ish psi since I sorted out the pipe to the boost gauge), I took her out last night, same thing happened to me... Found another more than likely break in the dett. sensor loom, so made a nice, new, shiny new screened dett. sensor loom, fine for about 10 miles, the safety boost AGAIN (I have the dett. sensor relocated to the top of the plenum, and it is NOT detting), so, I bypassed the dett. sensor with the old 1 meg resistor, and all seems to be shit hot now, goes like stink!

 

Been a royal pain in the arse, but got there in the end, but since the fettling, my tick over is now too low, almost to the point of wanting to cut out when I slow down at a junction, but that can be easily sorted... Hope it was worth the wait, it was for me, been a pain in the nuts, as it was a rather queer problem, as my gauge was telling me duff information, and it was still rapid, sure it was stock, not safety, as the last few times it dropped into safety boost, it was slower than the 9.5 psi, all strange, but sorted now :)

 

(Now you know why I didn't want to write this on my phone!)...
