VK T5 L67

Do you keg your Homebrew ?

Yes I do... Bottling is such a PITA.

Got a pair of kegs (and fermenters) on rotation.

Kegs and gas bottle live in my beer fridge.

To think I was paying $4 a glass at the pub... now about 30c.......

Cheers

Love this conversion!

Its not unlike what you did for your missus!

Totally different car to drive eh... Power when you need it, and better fuel economy otherwise.

Win-Win.

hahaha yeah that's it, I worked out about 28c a glass ..... I so need to get back into it .... my keg fridge stopped cooling so I need to sort that out!

I cry when I go to the pub, I get pissed at home for the cost of 1 beer at the pub, I wouldn't bottle it either, takes to long to carbonate and too much work !

[Holden202T]

washing the bottles needed to do it is the part i hate, i started with stubbies, then quickly moved to long necks and eventually the 20ltr kegs

Beer is proof God loves us, and wants us to be happy.

Totes agree, it is the cleaning/sanitizing part that gave me the shits.. I even used some PET plastic bottles to save capping..

In the end the kegs are the go.... Except the $45 quarterly cylinder rental (I've had the same gas bottle for a year now)
Yet its only $45 for the 'refill / exchange' ... reminds me to check my BOC account.

Still saving money though.

Edit, If someone out there need a very used (420k) but still serviceable 7HDD L67 '98 Transmission.. let me know.
In Victoria, I guess pick up or freight at your cost. (Also a complete VP V6 + Auto, but they're worth nothing anymore)

But, a set of much more useful slightly modified PH5009 Pacemakers for the Buick engine to suit VK also available.. (Slightly longer at the Y-piece to clear the chassis rails to the CAT. Useable condition, usual surface rust and shit.

No use to me anymore. PM if interested.

Where in ViC are you ? May help with the sale ?

i don't think the guy is still in the location he was, but he was a local place sold the bottle, was a few hundred but i own the bottle, just had to pay for him to fill it as needed .... worked out heaps cheaper than rental every year!

Time for an update and general goings on.

$%^^#$$!@!$, Where do I start?!

Okay, during the time I was correcting the low speed timing to cure the hunting and lurching I was logging regularly.

It was also this time I noticed how having the laptop connected interrupts BCM comms, so the low speed fan doesn't work.
Not good while idling in the Maccas drive through..... Watched the temps skyrocket and the overflow to puke after I got the thing out the gate and quickly parked it... activate low speed bypass plug NOW! (Grounds the relay so fan always on with ignition)

Fark... Everything settled down and we resumed our journey.

1st question, why the hell didn't 'fan 2' ecm controlled kick in? Is there a dependency other than the 6sec delay I can see in the code?

I've almost finished setting up a VR V8 style fan on the front of the condensor activated by a temp switch from Jaycar.. I'll call it 'Fan 3 '.

Next,

I had a pool of coolant under the rear of the supercharger.. in a recess in the LIM... looks like it came through the bolt!
Also a bad mis-fire getting progressively worse under load. Right then... LIM gaskets... bought a G-Force kit, it'll do.

Whilst apart, I knocked up a little rig to test the injectors, its a bit of a jury rig, but enough to kinda see if the squirters could deliver a reasonably equal volume of fuel.

New orings and filter baskets... they tested well.

But, this brings me to question 2... I still have a horrible split between the banks. lh+3%, rh -10%.. basically.
What to try next?

I have swapped O2 sensors, and even swapped to another set.. NTN vs Bosch. No diffference.
Swapped to a different ECM ('728) for a quick test.. no difference. (Well, Worse actually.. no LTFT memory, all STFT)
The earths of both O2 sensor grounds are linked ... slight difference.
I think i even managed to inadvertently swap the injectors from one bank to the other during maintenance.... No difference.

I haven't done a compression test, or changed the head gaskets... yet.

But general driving it seems fine, other than the data-log telling me it isn't. The miss-fire is still felt at full power, so it isn't fixed.


While rooting around putting the 'charger back on, I found one of the boost solenoid hoses split at the 90* boot.
The one from the tree to the solenoid. I figured, you know what.. I'll delete the thing, since I can't get my hand behind the head to fit another hose. Simple job.

Well it turns out my solenoid was playing up anyway.. the valve is now open at idle like it should be and its a lot quieter in general. Hmmm.

But a third problem is really confusing me. Fuel Pressure.

For the conversion, I bought a EFP-159 Delphi fuel pump. VS S/C internal pump. Perfect. About 48psi at idle.

Under boost (10psi pulley), you can briefly watch the pressure 1:1 rise to 60psi, then as the injectors open longer IT DROPS.
Yesterday I watched it fall to 38psi at WOT!

It can't feed the volume required at the required pressure. But, essentially it should. (Fuel filter is a Z168 large VK/VL style, should it be a smaller Z200)

Maybe I have to try fit an external 044 (or tre-200) and feed it with the delphi? Directly or use a swirl pot? At least this old EFI VK has a bracket for an external pump.

I won't mention the tree that tore my antenna off, or the front wheel bearing failing again, or the reverse light switch is now stuck on.


Cheers!

Edit, Attached a new log... '728 ecu fitted... 1st run. Nasty STFTs. Lean spikes?

Well it turns out these FPRs aren't boost referenced.

Remove the vac line on the fpr and the fuel pressure goes immediately to 60psi.

So its only affected by vacuum. The fuel pressure drops up to 10psi at idle compared to static eng off pressure. (This is normal)

Seems after changing aging/swelling fuel lines at the fuel filter has improved things(Tiny hint of a possible leak), pressure holds for higher load/rpm than before.
Decreasing to about 50psi at WOT... but I wasn't towing a trailer with firewood this time.

And yes this is private road testing. Can't hold WOT for very long......Poor sheep...

Need a second set of eyes sometimes.
