the trhead about the Mimi on TOO's site has had easily 11,000 reads; that's about 10 times what one of his popular threads gets. My guess is once he gets mine done, there will be more. We are keeping the stroke stock.

So... its just the piston "growing" a bit taller and a little shave of the head then? ;) (to slightly increase compression).

jlm, TOO & the :bad:-ass MINI... The saga continues!

V-Cool!

ok sorry didn't mean to :bad::bad::bad::bad: people off here. as far as my grammatics go. well i am an engineering students i really don't spend a lot of time esp. while on the internet bothering too much about spelling punct. and so on. yes it does get me in trouble, a lot. bad habit what can i say. as far as my knowledge base is concerned i would say that i may not be a mini expert on any level but i do know a thing or two. i work as a mechanic paying my way through college at usf for aerospace engineering and yes i own a 03 brg mcs. the statement about the supercharger well i should have been more precise about that my apologies also with the s2000 comment merely that it was designed to be based on the formula version by the same people. now the number of posts i have on these forums i do believe means absolutely nothing. thats it

The trade off is the pistons/rods have to be made right; the top ring land has to be moved down to keep the ring out of the heat and give more land support,.

What are your thoughts on the Smokey Yunick philiosophy of keeping the top ring further UP in order to better transfer heat from the piston crown to the cylinder bore?

yroc,

As a former engineering student (BSME) to a current one, you may want to practice non-inflammatory discussions and grammar/punctuation. It's hard for anyone to be taken seriously in the engineering world without those skills.

Smokey. My small block Chevy hero.
Is there any relevence between piston material and land height. That Smokey theory goes back several decades doesn't it?

Maybe it's intended to lull the Prof into a coma. Thereby sleeping through any potential technical inaccuracies in a thesis.
Wish I'd thought of that ;)
I'm kidding yroc. No malice intended.

You could just skim the head and/or fit a thiner head gasket. That would raise the compression. It wouldn't cost much either

I can't imagine why in this application, but there you go. :)

jlm has raised this issue with cylinder quench zones. Doing that would make the problem worse I'd think.

Sorry, must have missed that!! :eek:

True enough but there is that 400HP MINI out there, forgot which tuner did it.
BBR has a 275HP kit and they didn't even change any core internals.

But we're still back to numbers.
There are a LOT more Toyotas, NIssans and Hondas. Both companies have internal race development divisions that directly contribute to the performance mod market for their cars.
BMW may have this. MINI has JCW and they're not exactly stretching the envelope of the performance parts development scene.
So we're back to depending on smaller independent developers to get the parts out.
They can't do it cheaper.
Dinan on the other hand appears to just be overpriced. BMW snob value. :rolleyes:

The 405bhp mini is tuned by AMD in England and from what I have been told is not a bad bit of kit, AMD's way of finding out what gives first is to run it into the ground until something breaks then replace it with something more up for the job, only problem's so far is it stretched the head bolts and a noise from the lightened flywheel, probably the most suprising thing to date is the gearbox is doing fine....

I'll give you 50-1 that it doesn't make 150,000 miles.........:D :D :D :D
