I've recently been thinking about how to extract huge amounts of power from an inline A Series using high boost and exotic fuels. In theory, 500hp would be achievable from 1275cc, although much work would need to be done.

Speaking to a local chassis builder with over 30 years experience in this sort of thing, he said "How would you keep the crank in the block?". After a bit of discussion, we concluded that we would need some sort of girdle to keep the main caps in place.

The relevance to this discussion is that most high performance alloy 5 bearing blocks have a crank centreline above the sump flange. This creates a much stiffer bottom end.

Can you achieve the advantages of the 5 bearing block without doing the same?


They do something similar with the big bore Imp motors to hold the bottom end and block together

Quite easily achieved on an inline 'A' series I would have thought

1800 and in sump box, is it not an Austin Maxi setup ?
:-p

Madmatt, I do admire your dedication to the "go-fast" addiction and the out of the box thinking but the way I see it, it's much more fun if it doesn't cost an arm or a leg to build ...

Or maybe I am happy with that because I aim low ...

The V-tec (contrary to popular belief) isn`t exactly "lightweight" ,,, nor is it simply a "Bolt-in" item

Major,,, & i mean extremely "Major" changes need to be made with subframe, suspension, axles, body etc etc etc,,, it`s not an easy, nor is it a cheap task to put in & make work,,, let alone make it work "WELL"

Nor is "any" alternative power-plant swap into a round-nose... & then you will want to spend a big whack of time sorting the suspension steering, brakes etc,,, so it actually handles & stops

& on that point i must say that i don`t believe there is "Any" donk-swap that keeps that lovely "Nimble-ness" & sweetness of the original minis handling package,--> except maybe for the bike engine swaps,,, but again bike dog boxes on the road are yuk,,, & it`s only a matter of time before most of the dog-box bike engine swaps are going to need g-box overhauls anyways... ( & i don`t reckon that will take very long to happen,,, just watch)

& trust me when i say that hyabusa donks (with their tough boxes) don`t fit into the front of a std roundnose mini .... then there is money needed to be spent on reverse gear (ones worthy of Motokhana/autotest work anyway) would be needed,,, so even more time & money needs to be spent there to sort all that lot

there is soooo much time & money needed to be spent "Either-way" you do this, so at least the way i`m """attempting""" it keeps the minis brilliant handling package,,, it also keeps the subframe & body "Totally" stock-std so easy swap back if you want to,,, & no dept of transport engineering work or money needed to pass it for rego here in Aust

I`m not sorting all this "specifically" as a "Marketable" item,,, nor am i doing it to get rich (actually the opposit, it`s going to cost me thousands just to see if it works, & it may not actually work first time & i may have to spend another big chunk to sort it)

It`s more just for me & my own personal Monaco fastback mini,,, But if someone wants to take on the project after i`m done with mine then maybe Someone like John-K or our Chinese friends could make ship-loads of them so they`re more affordable to the masses ,,, maybe not too,,,, so what,,,, & if the "Maybe-not" becomes a reality then i`d be the only one in the world with it *smiley*

That`d be pretty cool too *smiley*

Now look,,, I must say that i Personally am not after the fastest mini in the world (with this project anyway), but if it becomes a reality & if it really is a damn good thing then cool

I have already built this-->



I thoroughly enjoyed building it,,, it was bulk fun,,, & a wonderful learning experience,,, i`m totally enjoying driving it,,, it """"REALLY-IS"""" Bulk fun to drive,,, if any of you think it`s not sooper-dooper stoopid fast then you are the ones who are nutso

It`s just simple physics,,, beating WRX-Sti`s & EVOs,,, on the dirt,,, standing start,,, not fast??? *smiley*

I`m now making it 4-wheel drive & adding the turbo, so it`s even going to be more stoopid fast

so, with this new mini engine package i`m not after a full house "RACE" mini,,, i`ve already got a few of those

i`m doing this as a comfortable, driveable, quiet, very torquey, smooth, very fast road mini engine , & it will be totally different to what "Anyone" else has powering their mini

If it works then i have what i want

if someone else wants to make a a kazillion of the main bits & sell them then that`d be cool too, but i`m not forking out for anymore than the one for me (or maybe 2... ok maybe 3) *smiley*

& yes of course a "decent" gear kit & case strengthening is part of the program

BUT,,,, a 5-main , Alloy block with steel cranks & rods to fit the existing mini box & all the alternative cyl heads can be born & grown from this base

that`s yet another (possible) bonus of this

Advantage,,, No sorry mate,,, not a Maxi thing in it

using a mini box, my own block & crank (sort-of) & a certain "off-the-shelf" cyl head & another brand of "Off-the-shelf" Main caps/cradle,,, & funny enough (at this stage) i`m using another brand of "Off-the-shelf" con rods,,, waiting to finish the wooden dummy crank to make sure of that tho

Leaving on Holidays to Byron Bay tomorow for 3 weeks,,, one more "Lack-of-sleep" to go

Just fitted 4x New tyres on the V8-Kombi, just paid the rego for it & the House rates, & another pile of assorted overdue bills,,, the holiday house rent has been paid,,, i`m off to the workshop to service the Kombi & replace the clutch lever, cable, bowden tube & clip,,, i`ll clean it all out of the crap this arvo & load all the food & clothes & surfboards & shit & i`m gone in the morning

have fun boys,,, i`ll see if i can click onto an internet cafe while i`m down there, just to annoy you all some more & see what more encouragement & criticisms i get in the mean time

cheers

If you have the material, I guess you are ready to start cutting.

Presumably you've done all the design and calculations by now. Have you done a FE stress analysis of the block? I would partciularly like to see the maximum stresses around the main cap area.

Have you also done a CFD analysis of the cooling water flow? If you are milling from solid then there must be some compromises in the cooling jacket. I would be very interested in how you have done it.

The Computational Fluid Dynamics are already sorted because i`m using an already tried & proven block (or rather the top section with the water jackets encased in that section.)

A Finite Element Modeling for Stress Analysis is being carried out at the Uni by a friend of mine

It`s all well & truly started i can assure you all of that

I can`t do anymore myself until i`m back but the wheels are in motion on quite a number of fronts & lots of things will be sorted while i`m away

gotta love friends in high (& far away) places hey?

Bye for now, love & kisses *smiley*

Well how interesting! I have had indepth talks with an engine modifier and developer about this very thing and have set aside a block to butcher.

He cradles the bottom end of some of his motors to achieve the power and torque figures he is looking for and keep the motor reliable. Its one of the many plans we have on the to do board and in his experience is readily doable.

Nice to know we are not the only ones looking forward.

Fat ugly chicks let you do things that the pretty and thin ones don't

Matt, you clearly missed the point. I used the Busa V8 as an example of adapting an OEM engine into something else. Some one had the idea to take two Busa blocks and design a new bottom end, they could have designed a complete new engine but they didn't.

There is the transverse Rover V8 sat ontop of a Princess transmission, granted its in a clubman front, but its in there and pretty dam close to the Mini transmission lay out.


Surely there is a modern engine out there, motor bike or car, that is a good candidate to adapt to the Mini gearbox, in a similar way to the old Manx Racing conversion.

Colin,,, You don`t know how wrong you are with regards to me missing the point ,,, I got that point exactly & well before i started this thread,,, read back a bit , "maybe" you`ll pick up on it *smiley*

I did that over 30 years ago Colin, i still have it here & i stuffed a turbo onto it too.

So,,, again,,, read back a bit & open your mind a tad & imagine for a minute that that is what i am actually doing,,, except there is a twist,,, *smiley* a reason for the big alloy block type crank cradle & crank that i`m making for it,,, a fair bit more capacity & a shit-load more strength may have something to do with it yeah>>>???

Or maybe you are right Colin,,, Maybe i have missed the point ,

easy isn`t what i`m after mate,,, Simple & effective "IS"

hee hee,,, I`m Brian & my wife`s Brian too *smiley*

I`m back from Byron for an Autocross at Willowbank tomoro,,, then zooming back to Byron for another 2 weeks of seriously lovely weather & lots more surfing





It`s a hard life living here *smiley* you guys "Obviously" have it way way better than us Aussies *smiley* *smiley* *smiley*

& last week i got a phone call telling me i am officially an "Invited Driver" at the prestigious Mt Cootha Classic Hillclimb *smiley* Cool as a cucumber *smiley*

so me & my little buggy will be tearing up the hill in 2-weeks time (the weekend that i get back from Byron) I just hope they past my car at Scrutineering , cross-fingers *smiley*

ok,,, well Byron was just wonderful,,, my trip back for the autocross was terrific & i ended up 2nd outright, the track went real hard Like bitumen & i should have changed the speedway tyres over to the slicks for the arvo runs, but hey... who gives a shit *smiley*

then, after going back to byron for another couple of weeks surfing & etc *smiley* i came back home , only to be invited to run the Cootha classic him,,-climb (see other topic) did well,,, but the dirt tyres were not really that good for the bitumen there either *smiley* 8th outright isn`t too bad for a $6ooo home built special , up agains some $100,000 full house hill-climb weapons,,, & beating Jim Richards in his mega-power GT3 porsche was a bit of a thrill

But,,, after all thet fun & games were over,,, i contacted a few companies regarding "Making" me a crank for my special little project & ,,, well,,, er,,,, ar,,,, crank shafts are pretty damn expensive to have made hey>?????

crickey!!!!!

I don`t think ill be making up any kits of this engine to sell,,, i might need to win the lotto to complete this engine *smiley*

who wants to be my sugar mummy????
