So has anyone compaired prices?
As in Piston and barrell kits, Heads, Cranks, Cams.
Between the two.

Ahhhh.... Paul. Thats him. Good guy, unfortunately dont chat here. 
He was the guy at the Nat's with the navy blue L Bug at the V Force stand.
He had the C 2's (Design 90's) on.
Hmm.... I still "REALLY" like those wheels.
Hmmm.... maybe i need 2 cars..........
That blue one looked good..... 7's all round...nice stance.
I dont care what anyone says, L's sit NICE with big Porsche wheels and lowered!

Nah..... off to Newmes tomorrow in the kombi . Wife wanted to go
camping over easter. I really stuffed things up with my escapade!
This has pissed the seller off a bit. I said i was going to pick up today but couldnt get a bank cheque today, and i wont be there till Saturday
morning! :P
Oh well..... i have said i want it and paid a deposit, so..........
Hey ... the motor is looking sweet.
It is like when he did the kombi motor..... some motors are thrown togther...... some are born with love and care. Yours has that same glow.......
I will be a baby.....

"stroker crank & chromoly race rods to match."
match?!?!
in a bootiful 1916..
*sobs uncontrollably*
noooooo noooooooo
does anyone know what the thermal co-efficient of linear expansion is for chrome molybdenum rods:P
i'm guessing they're quite resistant to creep... damn shame the rods are sized to expand to the right damn length WHEN THEY'RE
STOCK!
please tell paul to watch his clearances, and that the more he screws with the blueprints, the further out he's gonna be...
don't feed your racehorse sugar you'll KILL IT:o
alright. i'm calming down now.

It's always funny when people with no idea post stuff.
First I will start with the creep comment. Do you know what creep is? I didn't think so. Creep is virtually non existant until you get up to
around 50% of the recrystallisation temperature of the steel. I can guarantee your conrods aren't getting that hot. How hot did you think your
conrods got anyway? Creep is important in high temperature high stress components like turbine blades.
And chrome moly isn't a specific metal. Higher grades are stainless steels, which have an expansion of about 0.000016. Normal steels are around
0.000012. So the difference between the two is 0.000004. Say you conrods are 100 degrees hotter (not that your ever going to see that) than your
cylinders, and they are 100mm long. That gives you 0.000004x100x100 = 0.04mm difference in growth between having steel and stainless steel conrods. If
you are building your engine to that sort of valve to piston clearance, your crazy.
Besides, race engines use aluminium rods which have an expansion of about 0.000023, about double that of steel

geez Wes. Keep those people out of here and there'd be nuffin to read. Have you tried printing this shit out? I did ages ago and I think it was
about 50 pages
I still say 71 x 94 in a big block is the only way to go :thumb
Keep it up Jak. You got my vote for the next election. I'd have given up long ago. You got heaps of stamina.

Wouldn't this be a better choice?
2.0 litres, normally aspirated, 110 kW and 200 Nm of torque (ie as powerful and torquey as my 1.8t), direct fuel injection, 6.9 l/100 km combined fuel
economy (ie more fuel efficent by nearly 2 l/100 km). It needs a radiator but does come with a 120A alternator - no more dim bulbs. 
Downside: it will be a bit of a squeeze for non-Baja's, but ...
Hmmm, which car does this remind you of?

"It's always funny when people with no idea post stuff."
fully
"First I will start with the creep comment. Do you know what creep is? I didn't think so."
WAIT wait wait, i do, i just misused the term, not expecting to have to wade into a ridiculous definition war. i should have just said "resistant
to dimensional variation relative to temperature change"
oo and for the record, most types of chrome moly are highly resistant to 'creep'. hence their various industrial applications.
"Creep is virtually non existant until you get up to around 50% of the recrystallisation temperature of the steel. I can guarantee your conrods
aren't getting that hot. How hot did you think your conrods got anyway?"
About 100 degrees or so i guess, whenever I stickytaped a sender on them it got flung off into the sump... oo yeah and i agree it's kinda
insignificant on the CONRODS.
"Creep is important in high temperature high stress components like turbine blades."
just for the sake of definition (as you didn't bother to actually tell people what 'creep' IS) creep is when components like aircraft
turbines (ta wes) and highly stressed structures like boilers take so much heat and pressure and stretching that they deform and remain deformed even
after pressure and heat is removed. does that explain it Wes?
"And chrome moly isn't a specific metal."
no kidding. it's a whole series of alloys. so tell us what the difference between say 4130 and E4340 is... and then let me know what
they're using for those racing conrods. That would be more useful than making us digest crud like below :P
"Higher grades are stainless steels, which have an expansion of about 0.000016."
approx 0.000017 actually. and that's the unit change in dimensions per degree temperature rise. so for every degree one unit length of steel goes
up in temp, it's size increases by 0.000017 of that unit. just to nail down what the numbers stand for.
"Normal steels are around 0.000012. So the difference between the two is 0.000004. Say you conrods are 100 degrees hotter than your
cylinders,"
what's a co-efficient again? something to do with sameness or something...
at the SAME test temperature, different metals are found to have expanded more or less than other ones. hence the problem with allying (not
alloying)dissimilar metals with each other under the SAME temperature range when you're working to close tolerances.
"(not that your ever going to see that)"
bloody hope not :o
"than your cylinders, and they are 100mm long. That gives you 0.000004x100x100 = 0.04mm difference in growth between having steel and stainless
steel conrods. If you are building your engine to that sort of valve to piston clearance, your crazy."
i'm crazy, yes, but that has NOTHING to do with this discussion
"Besides, race engines use aluminium rods which have an expansion of about 0.000023, about double that of steel
|
FINALLY at the bottom of this incredibly boring double rant, I'd like to apologise for the ambiguity of the word "rods".
I was referring to 'pushrods' not 'conrods'
i thought my mention of the clearances was more likely to be assumed to have been made in reference to 'valve clearances'. duhh. my bad. but
chrome moly conrods don't have an amazing track record either (see the diff between chrome moly and chrome moly post
coming up from resident mech engineer (hons) wes.)
any idiot can confuse people with mindless statistics and tech talk, but they could at least make it relevant.
vw comes with aluminium pushrods. these expand at a very similar rate to the crankcase, and when the engine is hot, and the pushrods are hot,
everything's sweeeet.
*sigh* chrome moly steels, as wes pointed out, expand about half as much as aluminium. (i peg the co-efficient at 0.0000255) leaving your valve
clearances something like .010 out (i got that figure off a website, so don't quote me). that's pretty out. that's what i was warning
about, even though it seems the wires were crossed.
since you were having a go at me, wes, mebbe you could tell me what year VW made a QUAD CAM v6 for the beetle...
all of which has not a lot to do with the 1916cc motor.........:repuke

SHIT! I was going to relax this anzac day.
Now I gotta go and take my 10 year old pushrods out.
Someone form the 1916 brigade answer these questions based on my yr 10 science.
Jaks 2027 is burning more fuel so should have more energy there to begin with yes?
torque = force x distance is it not?
So the longer stroke the more torque yes?
2027's capacity + stroke = lots of torque gain?
and (not form yr 10 but something I hear regular enough) power = torque x revs yes?
2027 capacity + stroke + torque = more power yes?
2027 capacity + stroke + torque + power = WOOHOOO yes?
Seems potently obvious ( to this punter who may be digging himself a grave ) that 2027 is going to come out well in front of 1916 to me. If it costs
more bucks then so be it. You cant drive a porsche with volkswagen dollars.

mmmm, isn't funny that motor cycle engines have one of the highest horsepower per cc in standard form and they all have "big bore"
short stroke???!!
In fact most motorcycle manufactures went away from long stroke in the 70's!
use motorcycle ideas and formulas on your car engine and it will have the same horsepower per cc effect
Horsepower per cc is what I'm interested in.
In fact I would love to destroke my motor.
food for thought

revvvvs
someone better go tell the formula one people they've got it all wrong. 20,000 rpm.. hell yeah how awesome would that sound coming out the back of a beetle
craig's got a good point, horsepower per cc has to be the simplest test of an engine.
power comes from petrol right? the more you can burn, the faster you go.. if it breathes, and spins without too much centrifugal force on the crank at
high rpm it's gonna fly... like a gyro, or a light aircraft...
wes... serious question how much does ten grams weigh when it's orbiting around a point at a distance of 100mm, at a speed of 6000 rpm vs 3000
rpm?

I've thought about destroking too. Making a big bore big valve 1300 that revs to heaven. Take on the minis at hillclimbs. But I think it would
probably end up near enough the same money, and I would hate myself cos I know I could go faster.
