140bhp 1293? Hmm

It ran somewhere close to that in one of the mini world dyno days a few months ago,i think it was on his own dyno.

Is it a 5port?

Sounds like a sales pitch - his own engine on his own dyno in a magazine article.

I will concede and say that I could be wrong, but 140hp 1293 is EXTREME and I congratulate the man who built such an engine.

As far as i can remember it is a 5 port,i wouldnt like to say about dodgy figures but the car itself is pretty much a miglia from other pictures ive seen so id guess the engine is a good spec to suit.If it is making that much power then as you say its a hell of a figure from a 1293 (unless you go to baldwins i suppose)

i was looking into gettin mine bored to 1293 but i didnt bother as more people told me it wasnt worth it than told me it was

i was reading through what people have suggested, taking it all in before i do mine up

sorry to hijack in a way, but what is 'vizard'ing, didnt they do a lot with beetles

Reading and applying the methods explained in David Vizard's book

Just wanted to bring this back to topic. Can anyone suggest any good places to either buy a stage 3 (or whatever) cylinder head or have the work done to my current head. I live in Kent.

[Sprocket]

Bill Richards first and foremost, but then Swiftune, would get my money but it all depends what you want.

good old vizard

look into vmax scart heads really good heads and he is reasonable with his pricing. my superchared engine went from about 90 to 122.7

[01smartc]

Hi, we can offer you a modified head to suit your engine, all our heads are built to the spec of the customers engine rather than "off the shelf" stage 3 or whatever heads.

Im sure we can sort somthing out. Im sure people that have had a head from us will comment on the quality of the work and the extra power they produce!

If you want to sort somthing out drop me a PM

Cheers Chris @ Smart Performance

[mcaville]

I'm looking for a head that will give me lots of extra power but still retain drive-ability around town.

Looking at what's available it seems as though there is quite a lot of variation out there. Anything up to 38mm on the inlets and 32mm on the exhaust. And then there's what cc's you want for the chambers. I'm going to have a look and see what Vizard has to say, but does anyone on here have any preferences??

[cap'n crunch]

Even without a re-worked head you should be making more than 60bhp @ flywheel on a 1293. For example when i took my 998 to Gerald Dale i got 60bhp...

[steble]

for your car i would have said a 35.7mm inlet 29 or 31mm exhaust that has been well ported a skimmed for nice compression would go down quite nicely.

but to be honest your best off going to vmax or med or swiftune etc and asking them. it's in they're interest to get as much power for you as they can. and a head wont really damage your ability to drive around town etc its when you start putting cams and stuff in you need to worry about that.

cap'n crunch
you would have just been lucky getting that sorta power from a 998 it happens radomly they are only meant to have about 30 standard but a couple of months ago my friends standard one pulled 52 on the rolling road and another friends 1275 stage one got 51bhp lol. every mini engine seems to do something different its really quite random

[kenzie22]

Well I've got 72 out of my 1293 without any extravagant mods...

1293 A series
K&N pancake + stubstack
HIF44
Water heated inlet manifold
Cooper S head
LCB exhaust manifold
Maniflow single box 2" exhaust
Electonic distributor
Unknown camshaft
Red engine paint
Fluffy dice

I did also 'Vizard' the carb and inlet manifold which is well worth doing! Costs no money and helps your engine breathe its best. Didn't even have to buy the book, just got it from the library... If you want to go a bit further the book also explains how to modify the head (or if you're buying one, then what to get).

Its got nothing to do with vizarding its the fluffy dice giving that power

i dont think its been said yet...quite supprised to be honest...what cam has the engine got? obviously this will make all the difference, what timing does it have, rockers etc etc, it all makes a difference aswell as how well the engine is built, eg, engine balance, cam timing, tollerences

I bought the engine off of a guy on here - Andy B. Apart from the fact that it had been bored he didn't have a lot more history about it than that. He said that it might have an uprated cam in it but he couldn't be sure. he had bought the engine off some guy for a project but had never got round to doing anything with it. So, as far as i am aware, apart from the bore and the exhaust and carb everything else is standard. Effectively it is a 1293 with a stage one fitted.

[mini93]

then honestly, i wouldnt be so supprised, as said by someone else previously the meer 18cc difference unfortunatly isnt going to make bugger all difference, it actualy a standard engineering oversize, one of which you dont neeeeeed to tell you insurance about (though it *shouldnt* hurt if you do so)

if you want more power take the advice elsewhere, work the cylinder head and uprate the cam...while ensuring the engines built propperly. Rather than getting expensive timing gear you can get offset keys which will allow the cam timing to be optimised...saying that im sure you want a drivable mini rather than an all out larey beast there for shouldnt go for a wild cam, you may well get a decent head but its usualy comes down to the lowest spec part limiting the engine, ie you may have a 300 degree cam but if the head breaths like an asmatic it will only produce the power according to the head, like wise nice large head but tiny cam opening times means you wont get decent amounts of air in.
