Create a variable spark gap to measure voltage. Rule of thumb is around 3kV per mm in free air, compression makes a big difference though. Can easily calc the spark gap under various pressures.

You can also calculate coil energy by monitoring dwell charge current and coil discharge current on a scope. Power supply average current is not really a good indication, need to look at the current on a scope and integrate it.

Difference rules of thumb seem to exist for open air gaps but I found 1.1Kv/mm to be the most verifiable. eg spark length = specified output of a HV transformer or PSU and 1.1Kv/mm seems to be spot on with conducting 100s of ultra high voltage experiments from early high school days.

An update once again.

Not a whole lot as I have been using the almost all of the holidays to install corrugated foam inserts in the shed roof ridge capping and down near the gutters.

I thought it would take 2 days max, well I was wrong, more like 2 weeks lol. I fucking hate DYI handyman shit, that crap is not for me. But anyway 99% done and needed to be done as it was a loosing battle dealing with weather and leaves, sand, flowers, dirt etc... dropping in through the roof. Next much bigger project is to replace all of the walls and have custom flashing made to rodent/draft/dust proof it all. Thats for another time I think lol. 250m2 is no small job.


So I managed to finish off the engine with the sump done, I actually did this mid December well before the holidays but didn't get a chance to update on it.

I removed the temp sump and prepared the block for my drilling and tapping jig. It ensures everything is drilled and tapped dead vertical.

hole drilling.

I drilled to 16mm deep.

Proceeded with 1/4" UNC intermediate tap and then a bottoming tap. 1/4" because this one screw on the ecotec sump is in a slightly different location to the Buick one and close, where tapping to the Buick 5/16" would cross over into the existing hole. It works out perfect as the ecotec stock screws are 1/4" and the Buick ones are 5/16" and the great thing is the holes in the ecotec alloy sump are 5/16", so drilling all the rest to 8mm you get a nice firm fit on all the 5/16" screws, effectively pinning the sump to the block.

Next I filled the old hole with epoxy, I used JB weld. Note the 2 holes filled on the No. 4 main cap, those are unused on the alloy sump on the ecotec and also due to the closeish proximity to the one of the edges of the sump I figured it be best to fill them to give the most surface area for sealant as possible.

Mmmmm so satisfying

Then a good final clean. I did this while the paper was still sealing the engine so I could give the surface a rub and also flush out the thread holes with solvent as they were to be sealed with sealant and loctite.

Thin coat of permatex max oil resistant sealant. Only the bestest!

Same thing on the sump side only even lighter coat, literally just to "prime" the alloy to ensure no dry air patches and full bonding.

The fun part! I put the sealant under the head and the top half of the thread, bottom half I put loctite blue medium strength.

TB put together, looks good. Just waiting for the new TPS to arrive. I had a heap and seems most were broken from I guess catching on the firewall when I had stripped the cars they came from.

So that was it before the holidays.

I managed to get this done a few days ago.

IMG_1345_zpsbit1nbsg.jpg (221.44 KiB) Viewed 3179 times

And finished yesterday. Now I have a V6/T5 specific power-train cradle It will allow me to mate the box up to the engine and keep them off the ground instead of hanging it for months on the engine crane, which I need to free up for removal of the old engine and moving of the diff when its needed.

Today I started finally on the car, hadn't been touched really since March or April?

I used a hand pump to suck out the fluid via the dip stick tube and it looked sad. There was only 1.5L in there. it was full last time I checked after the auto blew? Must of leaked out, it was pissing out the TC when I last drove when something let go in the auto.

I then used this method to remove the rest.

Worked well until the 3rd time when it finally ran dry, fucking mentos and diet coke explosion! bottle was half full and then bang!, foam blasted out like no tomorrow and even after the engine was shut down and I took the bottle off the oil just kept pouring out of the bottle due to the expanding foam. FUCK! I used a whole curtain as a rag to clean up the mess, was about 2L of fluid on the floor and under the protective cardboard I put down.

I hate autos, grrrr

Anyway I got to a good point, most of the stuff out of the way and disconnected. Should have it all out tomorrow.

[psyolent]

yes. i need this

IMG_1346_zpsz1htx0he.jpg (183.21 KiB) Viewed 3179 times

did you use 1" SHS for that? i cut my 50x50 SHS for mine over the hols but ran out of time to buzz it together.

bloody nice work on that sump too. the only thing i've have done different (which i did on my 5 litre) was not use bolts - i used all thread coated in sealent and nuts/washers. my 5 litre is the only thing i know of that doesnt leak a thing - it just burns oil instead. its bloody amazing.

[Holden202T]

lol @ auto puking even when you shut the motor off they bleed pressure down for ages and keep going

stand looks good, I have made similar ones for holden 6's and V6's to make them easier to store!

[vlad01]

SHS? are you referring to the 90º upright bits at the front? If yes, then yes its 1" x 1"

no it was the bottle not the line that was spewing. It chucked gased up fluid in there which then expanded like a shook up coke bottle. I ran with the bottle over to a big rag on the floor and let it spew its guts there, was doing for about 20 sec.

[psyolent]

SHS = square hollow section vlad. typically blue tube. the base looks like it.

i know your love for tranny fluid just changed the fluid and filter on the track car. yuck. shit job on the ground. and its farken hot outside.

[vlad01]

its 40mm x 40mm

[psyolent]

right.
whats the plan for the red rocket VSH?

Total restro.
