Project Freeze My engine Off (SAAB B207R Supercharged)

[evocarlos]

special

i like shiny new tools

You will need a second bat cave soon!

got plenty of room now i cleared it out you will have to pop down and have a look

I do like the mitutoyo verniers used to use their stuff when I work in fabrication, we found it much more accurate than cheeper brands and better life span.

yeah there nice but a bit steep at £118

right went out and did a bit of playing with the crank
cleaned all the holes out with break&carb cleaner with my new brush


journals are all clean and tidy now the shaft is still a bit dirty hopefully it will get cleaned if i use it


new tool made life easier


each journal got measured 4 times
w1 = woodruff key end w2 = same journal but other edge
f1 = flywheel peg so 90% difference to w1 and f2 is as above
some mixed readings but engineer dad says after .00 theres not much difference


used z22se crank has 55.980mm on most
brand new saab crank 55.993

Would love to pal

 

[corsaZ22se]

that cranks good enough for a couple more spins then!

your more than welcome to pop over some time just let me know your coming and i,ll wash my hair lol

it looks that way 3-4 billion

took some measurements from the SAAB crank
hardly any different

 

[evocarlos]

I have now got the right ones for measuring the inside of bits


and the micrometer 25-50mm just for measuring the rod journals


not had chance to use them yet have been fitting climate control to a mates van

Nice tool collection building up there Carl

Nice tool collection building up there Carl

all added to the collection now will have to start buying cranks and measuring them lol

measured up the big-end journals all 49.0 time to send the crank to http://www.andrewsprecision.co.uk/ for balancing will see what there cost is for knife edging lol


dug out the saab thermostat housing and compared it to a z22se one

 

[vocky]

just to let you know the Saab thermostat housing will hit the F23 gearbox if you try and fit it. It cannot be made to fit, it is cast the wrong shape

The left hand side of the housing in your picture is where the problem is located.

hey neil
think you mentioned that earlier on in the thread
i picked up a z22se one for free im just looking for a way to adopt the oil cooler to the z22se system as the astra dont have any oil cooling system at all unlike the vx220

what about the net thermostat housing on the m32 much room there for it ?

 

[evocarlos]

fitted the oil drain bung
fits well and looks like the o-ring will hold it shut


got bored and put the top back on it will have to stay like this for a while now need parts

 

[vocky]

if you haven't used any engine sealant on the 'bung' it will pop out and blow oil everywhere, this is due to crankcase pressure.

No idea if the saab thermostat will fit with a M32, I have an electric pump set up

its an interference fit i had to hammer it in with a punch real hard its tighter than a core plug
ment the o-ring will seal it for oil so it dont leak but i dont think it will get that far

gonna take the z22se thermostat housing for sand blasting then adopt it to fit the oil cooler

so many little jobs to do waiting on pay day for pistons and rod lol
gona make the call now to see about the work to crank and the prices

 

[vocky]

what work to crank ? balancing ?

vibration free quoted me £365 for full balance - crank, rods, pistons, flywheel, clutch cover and crank sprocket.

andrews precision
quoted me £120 for all of the above
but i want to ask their price for knife edging but not extreme im not wanting a butcher crank lol

Hello Carl

All medium size 4 cyl crank units are £70 for the crank/flywheel/clutch/front pulley plus £30 for the rods and pistons, making £100 in all.

All prices subject to VAT at 20%

Each component ie flywheel/clutch/front pulley is added to the crank and individually balanced so that each component is balanced in it's own right.

Let me know if you need any further information.

Regards

Hi Carl

Yes, we zero balance cranks first and then add each component (flywheel,clutch,front pulley) balancing them as we add them.

By all means buy a lightened (steel?) flywheel but it's a good idea to balance it on the back of your own crank even though it has been machine mandrel balanced.

We end for end balance the conrods down to zero and match weigh the pistons, again to zero.

You don't need the balance shafts for performance, they oppose secondary forces but effectively are trying to tear the block apart.


Regards

Trevor

just got off the phone with them
the knife edging and balancing comes to £240-vat
im taking the crank over to them now so he can start knife edging it then send him the flywheel and pistons and rods soon

 

[vocky]

you do realise that all the mad doc's knife edged crank engines self-destructed don't you

im not the mad doc
and im having the crank done by a guy who has 30 years experience of just working on cranks hes not going to be taking to much off
he showed me one off the shelf next time i see my crank it will be lightened and balanced

 

[Dave Gilbert]

So whats the advantages of having the crank knife edged?

looks nice though?

more oil dynamic and lighter meaning better engine spin up time
think of more aerodynamic but with oil cuts thru
and the cost of this crank and the work is still cheaper than a bought one i also get the chance to get the crank checked over by an expert before fitting it to my engine

 

[Dave Gilbert]

i thought it would be like cutting through the oil to make it spin faster

its gonna be a monster.
