Various Issues

[Revhead]

When it's trying to limit the boost, the profec in your car makes a fast clicking noise - that's the solenoid opening and shutting to control the air pressure the wastegate actuator sees. The noise should be easily heard inside the cabin if you turn the stereo off.

If you want to bring it back down I'm happy to have a look at it

[Revhead]

OK... to connect the wastegate directly to the intake, connect the line coming out of this:

to a line coming out of somewhere along here:

The plenum is the best place to connect to but anywhere along the intake between the turbo and the motor is fine, as long as it's after the turbo it's ok. Hell you can even steal the hose going to the BOV, you might need to extend it but it will work - pull the hose off the end of the BOV and plug it into the wastegate actuator. Obviously this means that the BOV won't work, but this isn't a huge problem if you're only doing it for a short term to test something.

Awesome info, but was dissapointed to see red bits instead of pink bits

I'll bring it back down if you want to pay for the petrol?

OK I'll take the pipe that goes from the wastegate and plug it into the plenum sometime this weekend, thanks dude!

Alrighty, hooked the wastegate to the plenum, stole the feed for the guage so dont know exactly what boost I am running, but it used to ping it's nuts off in 3rd when it hit full boost (between 0.9 and 1.13 BAR) and ran it up and down the highway and it was considerably slower and did not ping once, borrowing a workmates t-piece tomorrow and might whack on his boost guage to compare it with mine to see if it is accurate.

Also found an awesome welder who will add about 1cm of steel to the floorpan/handbrake foot and is a great welder, will work for beer, so when he gets back from his next mine stint, I'll get him to weld up the mount

Alright, finally fired off some shots of the handbrake mount, and here they are. Not too sure how they will turn out, as the sizethey are automatically reduced to is a bit small, but I can email you the full-res shots if needed.

For some reason I'm having trouble uploading to the SAU gallery, is anyone else having this problem?

Cheers Nick, thanks for that mate.

[AlexCim]

we are all so helpful to eachtother on this forum, its a true place for knowledge exchange

[GoldZilla]

Yeah, that's why I'm happy to contribute to it as well. It works both ways!

[Ska]

Yeah I really do apprecitate everyone's help on this, looks like I am going to get someone to weld two bits of 7mm thick steel, one to the floorpan and the other to the handbrake foot and then bead weld them both together, that way it aint NEVA coming off

Thanks again!

Umm, I did so, just for you matey, but they were a bit 'dirty' so had to put them back again. Please dont ask me to do that again - wasnt a very pleasant experience. Sorry.

Does it look like I care! Get back up there and get them, just like they pulled out those two miners............ in tasmania I mean......... anyway, seriously I realllly need to find a supplier for them eh,

Right bought an elcheapo boost guage and hooked it all up with the plenum to the wastegate and cant get it past just on 7psi, and it takes much longer than it used to to get there, so it looks like there is something wrong with the profec or it is setup wrong, bummer, which means I might need to drive back to brissie to get it replaced under insurance......

If you have the W/G hooked up directly to the plenum then you will only ever get 7psi as this is what the W/G spring is set at - at least you know it is working fine.

[Ska]

Yeah was the whole point, now I'll check tottally the EBC and see if everything is hooked up properly and check it all one last time and see what it boosts to, if so, then it's stuffed I guess

[CruiseLiner]

hey cyrus u dont need to weld anything onto the car floor for the handbrake to make it stronger, just weld bigger support brackets onto the handbrake assembly itself so the bolting down areas are much bigger, and use 2 nice big nuts and bolts to hold it, trust me when its bolted on the gearbox tunnel it doesnt move an inch and doesnt distort the floor or nothing. saves stripping interior and burning all the under carpet deadener and stuff

im the slackest for getting photos but ill make an extra effort to take a photo of mine with the console off to show you what i mean, soooon haha

cheers

[Ska]

Muchly appreciated Brad!

Don't just hook it all back up exactly how it was - get your copy of the Profec wiring/hose diagram, and...

1. Follow every single line and wire back so you know what and where it plugs into. Draw a diagram. Compare it to what's on the official one. Make changes if necessary.

2. Take every hose off, one at a time so you can't mix them up, blow through it (with an air nozzle if you can get your hands on one) in both directions so you know it's not blocked, or replace it if it's old/cracked or blocked for no apparent reason.

3. Cut the extra length out of the hoses, as I know yours are ridiculously long Just cut enough out to make them tidy, but leave plenty of slack in the lines, and cut from both ends, not just one. Make them (say) 10% longer than they have to be to reach. Cutting from both ends makes sure that the bit of hose you're putting over the fitting at each end is in reasonable condition. Reconnect the line, then repeat 2-3 for each one.

4. Check the wires with a multimeter for continuity (huge resistance levels = broken/dodgy wire). Check them visually for frayed/missing plastic sheath, replace the wire if it's stuffed. No twisting and taping... do it properly!! Crimp plugs onto (or solder) any cut wires. Check again for continuity.

5. Reconnect everything one at a time, double checking that you're putting it in the right place.

Then, try driving it again with the Profec off, if it still runs stupid boost stop there and reconnect the line directly to the wastegate, and take it to someone who knows Profecs (or at least EBCs in general), have them check it and tell you whether it's shagged, or something is wrong.

Yes this is time-consuming, but doing it yourself could easily save you $$$ and possibly a trip to Brissy - I've bolded the important bit

If you have a mate up there who'll do this for you for a carton or whatever, do that, just make sure he knows what he's doing, and that you don't give him the carton until after he's finished

Thanks Revhead, will try all of that when I have the time

Also does anyone know why one side of my EBC goes to the wastegate, but the other goes to a T that leads to the plumbback to the turbo (effectively before the turbo) and the other leads to the intercooler piping, just before it bends around to go over the motor, (effectively after the turbo)............?

See Pic:

Key:

1 - Plumbback pipe goes to T

2 - Intercooler pipe goes to T

3 - Goes from T to GReddy unit in the engine bay (see pic below)

4 - Wastegate goes to GReddy unit in the engine bay (see pic below) <-- This currently goes to the plenum so that I run stock boost until I figure out what is going wrong with the GReddy EBC.

Pic of GReddy engine bay Unit: (The two pipes hook in underneath)

Now at the very back of the stock plenum there is a hose that runs off that to the incabin GReddy unit, not pictured. I assume that the wiring then runs from the incabin unit to the engine bay unit...?

Also notice that the engine bay unit is mounted on the firewall, meaning that the hoses running from the wastegate and the T (pictured above) are about 1mtr long .......

Still next step for me is to follow Revhead's instructions above and test/replace/change/check/double check everything and go from there.

But what I dont understand is why the EBC would be venting boost into before the turbo and after the turbo? The instructions for the EBC show that the vent should be hooked directly to after the turbo, not before it....

But then it begs the question of it worked perfectly before with this setup....... so if it is not then either a hose is leaking somewhere, the wiring has been damaged or the EBC is broken.........?
