5-main alloy block with steel crank & rods to suit

Oh & i see a little Marlene left nipple sticking through her rashy,,, maybe it was a little cold after all

oh yeah,,, & i thought the rods & block was such good value that it would balance out the cost of the crank but crickey, i reckon they`re wanting to retire on the profits of making just my crank

Oh & the surf wasn`t so big the other day-->

what size is the longboard your riding in that snap?

I love the smaller days on my longboard, everythings alot slower, and you can just mess around with cross stepping and all that.

I didn't understood quite right.

You sourced an alternative block or had one done ?

If it is the first, then why don't you use it's dedeicated cranck and mate it with a chain drive to the mini gearbox ?

And what was the plan about the gearbox anyway ?
Isn't it a known weak link even in full race trim ?

All valid points but Its Mad Matt we are talking about here.

Where there's a challenge there's a will. Where there's a will, there's a way. Right Matt? :)

Oli,,, mine is 11ft (i have a pile of other boards of various sizes) but as you well know , on waves this "BIG" ,,,well i think i chose the right board for the day hey? & Marlenes board is 10ft

Advantage,.,, this "thing" that i`m attempting to create is a bit of a mix-match of items,,, the block is a 2-piece item,,, the top half is from an already existing engine & i`m making the bottom half to suit the mini box but with 5-mains & is a full cradle type thing, bolting the 2-halves together & then sleaving bores deeper into the bottom half, if you get my drift?

the rods & pistons are off the shelf items,,,

so hence the crank needs to be made to suit... & i need it longer in stroke than the crank that usually goes with the top half of the donk ,,, if you get what i mean? can be up to 79mm bore & 91mm stroke , if you really wanted but the first one i`m doing will be only 86mm stroke,,, then we`ll see what happens after that

& Colin,,, you`re spot on, (as usual)

& for anyone interested, this is more an exercise for fun than anything else,,, I`m sure that if i told JK about it all , gave him all the details, that he could whoop one out of his machines in no-time flat,,, i really do expect this to be a pretty decent engine compared to anything else fitted to a mini in the history of the world,,,,

if it is do-able... & if it is nice,,, if it is smooth drivable torquey broad-spread yet rev hard type of thing like i`m expecting it to be ,,, & if it lasts... & if the box doesn`t mind it too much, then i`ll have a "one-off" roady donk all to myself,,, as i said before i really don`t expect many (or any) other people would want one ... i`ve no idea about that until i get mine working & see what it`s like,.. maybe people will be bashing my door down to get one,,, maybe no-one will want one (especailly after they see the price) ) ,,, but if/when that time comes then i`d be more than happy to share the knowledge,,, if it all works that is (by rights it should tho, it`s looking good so far)

sorry i can`t really let too much more out of the bag right now,,, (as much as id love to & i really do want to let you all know exactly what i`m up to,,, i really do,,, i`m busting at the seams to say what all the bits are from) But, i just don`t want to say it all now, only to find it doesn`t work ... nor would i like anyone else rushing in & beating me to the punch,,, you know how much i like comming first, just ask my girlfriend

Ive also been working on a single -over-head-cam conversion for the mini engine,,, leaving the 5-port mini head on & adding the upper cam cradle with buckets , narrower springs & caps etc & a flat cam cover on-top of that,,,etc

pics of that one shortly (once i work out how to get the pics off my new phone onto my computer

www.miniman.com.au

"""LazyGoodForNothingSmartArseKnowItAllBackYardMiniMechanic"""

& here`s "one" of the single over-head cam carriers we`re playing with,,, (This one`s a ford one) i`m doing a few different designs (for a few different engines) & will sort out what`s best & what`s not



there`s quite a bit of work in these things & this (being our first attempt) has already shown some flaws in my design, so we learn from our mistakes & make the next one better-er, hey?

the short alloy shaft laying ontop is just a dummy cam plug, so don`t hold to much concern with it ok?

matt is a smart guy, he knows his stuff.

I don't see anything wrong with the A+ engine? it can well you get high enough power for most people.

i reckon alot out there who love & drive there mini with fun and have a nice poke, wish some one would make a normal type gearbox to handle 120hp 130hp atw's for a everyday car.

mini's have proven 130 atw and more on a everyday car or nippy fun road car why would you need more?

it's the gearbox thats the problem.

not stupid screaming straight cut gears.

one day some one will fill the market with a decent 5 speed box, with a proper overdrive & when they do, ill be buying one.

i reckon some Bike gears would work & fit in a mini box.

then i know a mini is more an older car but then what about safety, it's a 60's design. you crash you die.

who knows! good luck.

I like the over head cam conversion !

You're machining what I don't even dare to draw !

You are the "papa" !

Rusty by nature

Oh Matt you fucker!

I'm really intregued by this, do you have any details you can share? I'd love to ditch the push rods on my 7 port.

Nice idea, i hope you do succeed this will be great if you do, not sure if i missed anything but are you going to be using a standard gearbox case? and what sort of head do you have in mind? good luck with it i'll be following the progress. :)

About what I said earlier :

Rusty by nature

Thanks Guys,,, well there`s really 2 things going on here,,, one is the 5-main donk with a "certain" Multi-valve cyl head,

the other is the ohc carrier for the 5port (could be set up for a 7 or 8 port too)

The 5-main is progressing slowly,,, lower block-half has been machined a fair bit (no-where-near finished tho) in a way it`s a good thing tho cause we`ve noted some issues/flaws in design that we can correct now, before we go any further (Whew!!!)

The ohc carrier is fumbling along quite well, altho smaller diam valve springs/caps etc & taller/longer valves are needed, it`s a cost we expected but not a cost i like either

i wish i could give you all the entire guts of the info on both these projects right now,,, but until i see some light at the end of the tunnel on both of these , well i just have to keep my gob (typing finger) shut for the time being

the word is out tho,,, there is a pile of people talking about this so it`s all good,,, but i need to actually make it work before i say anything else,,, (once bitten ,twice shy , if you know what i mean)

Progress is slow (as per usual for me) but still each day i try to sort "something" out on both of em

but to refresh people`s memories,,, i`m only doing the 5-main progect for myself atm,,, i can`t see anyone else dumb enough to fork-out the money needed to make one of these

however--> racing & refining my R1-buggy,,, & testing & tuning my Turbo Bimmer Twinkys are all "time-suckers" too.

then there`s the surfing nearly every week

Oh & i have LUNCHED/MUNCHED the gearbox in my V8 Kombi (again) so it`s off the road until i can sort another $4000 to fix that fookin thing (again) that`s now gearbox number 10

I`ll give more updates as we progress tho, but "What-parts" i`m using on these 2 projects will remain secret till the jobs are done this time.

cheers for the nice comments tho, i really appreciate the encouragement

& yes all this stuff can be used with the std A-series g-box ,,, but we have plans for a "decent" box,,, just that we have to learn how to walk before we can run, & learn to run before we can fly & learn to fly before we can blow up another gearbox (mini &/or Kombi) , & learn how to blow up gearboxes before we can learn how to modify something else which takes the power better

whew,,, getting sore finger tips

ok, we`ve had some progress with this 5-main crank, with alloy billet block

we`re now (changed our minces) & making the first one a 1435cc & once its done some decent road & race time we`ll look at going bigger in both bore & stroke

pics of alloy block & my first "mock-up" crank soon

any progress?

I`m a little short on money for the crank atm, sorry, & too busy fighting off alligators to realise the original intention was to drain the swamp... if you know what i mean
