Somehow I managed to survive 50 k miles in a 220bhp Seven with 195s . Educating a right foot is a useful skill and remember that when dinosaurs stalked the earth people cheated death fairly easily, even in 155 shod Elans and 185 shod E-Types.
Snap . . . And I bet they were 13" too ..... but we best not go there eh :-)

When I read "wrings" I thought for a moment "Ah! That must be a fantastic n/a engine tune!". Alas I see it's just another turbo conversion, which all in just about manages to make it as quick as a bloody fiesta.
I find it all deeply uninspiring. I like the new mx5 a lot, I just wish someone would do the right thing and give it a proper going over. It's like actual engine tuning is a thing of the past. Everything must be all things to all people, which ultimately just makes things boring. Low down torque? Mid range shove? Might as well have a diesel.

I wonder how they are controlling the knock. I thought these skyactiv engines were about 14:1 compression. My understanding is High compression plus big boost is a bad idea usually.
Got to be running close to a bar of boost for that sort of power increase.
Pretty impressive on paper!
article says .7 psiGot to be running close to a bar of boost for that sort of power increase.

I do think that bbr have chased big numbers because that's the state of the market. I suspect a lighter boost would probably be a better drive, and in keeping with the character of the car.
having charged my own 5, next time I'll pursue (expensive) NA tuning.

Oops, missed that. I do think that bbr have chased big numbers because that's the state of the market. I suspect a lighter boost would probably be a better drive, and in keeping with the character of the car.

I wonder how much they can extract from the engine na, without doing big internal work.
They must be finding power outside of just forced induction, 131bhp na to 213 on just 7lbs seems like quite a bit! I may be missing something, or getting confused about the physics of it. Where's max torque when you need him

They were indeed - and yes , yes , I know why 13s are best for real men. Ironically I now have a 2 litre MX5 ND and love it - I lose no sleep because some horrid man on the internet said my gearbox was crap (it isn't actually , but some are apparently ) and do not feel my manhood shrivel because some hot hatch or other is faster to 60 , and/ or round the (yaaawn ) Nurburgring . Another 40 or 50 bhp would be nice , but not via a turbo thanks - and steering with a lot more feel would be even nicer

From the 2.0 ND Skyactive engine BBR can get 214bhp ish without major internals, just cams, exhaust, intake & map. This jumps to 225bhp if they flow the head. Torque is also very impressive, a strong attribute of the mazda engine design.I wonder how much they can extract from the engine na, without doing big internal work.

Ha, concur with all that !!The BBR S200+ package for the ND is really good and for 'post caterham' owners adds a bit of extra spice to the mix.
BBR's work feels proper OEM and I'm sure the turbo versions are great, I just like NA.
Steering feel, yes how on earth did they get this wrong in such a car !!?? If they improve it in later iterations I may consider swapping the rack !!
My gearbox seems to be holding up too and is an absolute joy to use.

Really grates that BBR do this, what percentage of sales are business-to-business that justifies displaying prices ex. VAT? I bet most of their business is to private individuals and so their prices ought to be inc. VAT.
PH, please can you correct the prices in the article to reflect the VAT status of those price?
It is for overseas buyers. Lots of Americans and Europeans buy MX-5 related stuff and these kinds of kits from BBR. They don't pay UK VAT. PH, please can you correct the prices in the article to reflect the VAT status of those price?

I wasn't aware of this?Actually I am aware of a few (small) proportion which have not been involved with Rodders. Lets just get that out there as well as who.
At least one of those cars in the initial instance had Mazda investigate and find nothing as it was only intermittent. Then it began getting worse mostly with 2nd struggling to engage properly, prior to going back 3rd had also began to have issues. The car in question was low mileage and had never visited the track or been abused.
End result was a very young car with a new gearbox. Ever wonder why the Fiat version uses the MK3 NC gearbox?....Yes the 6spd in the MK3 could be notchy, but issues are rare (speaking with Richard at Blink the only things to be a potential problem even when racing is the selector fork due to it being plastic, they swap them out with a metal version).
The fact that the US racing versions get uprated ones is just rubbish. MMUK won't even offer it to the racing boys over here.
The NC was not perfect with some of the oil surge problems granted, but it did not have such poor quality components early in life.
If focusing on aftermarket then hopefully the skyactiv aftermarket turbo manifolds are better and stronger than the NC ones which even with lots of development for turbos still are not perfect. Hence why a few like Blink switched from turbo to supercharger (Corten Miller setup).
