Spot on with the remap. Even after putting a 75 cam and a BMC filter in mine it feels fluffy at times. Already booked in for a remap.


I've got a BMC panel filter awating fitment, along with a Supersprint backbox - someone on FF is selling a 75 cam (I've asked him for a price) - so I'd be very interested to see how you get on with your remap.

How much is it and where you getting it done?

Angel Tuning are coming to see me early next month, club members special price of £175. Have a ring around and see what others are charging!
The car had already been remapped with all standard engine bits but it feels like it will benefit from a remap again now.

John - re: the Mini cam settings. Does having siamesed ports and a much higher emissions limit affect the outcome?

can these units (SPI in particular) be reprogrammed through the diagnostic port or does a new chip have to be written and installed?

SPIs need to physically have the chip changed. MPIs can be reprogrammed via the OBD socket.

Is £50 delivered a good price for a 75 cam? It's supposed to be in excellent condition.

I would have thought that to be a bit expensive. You could get a whole 75 head from a breakers for less than that.

Missed this post. Have done more research and some more in depth measuring, figures adjusted accordingly.

Why are the exhaust tappet clearances different for the 1108 and 866 cams?

That's how the designers want it, will be to do with ramp angles etc. I assume.

i was just looking at cams as i now have my spare head to play with .. went onto the piper site but they only had a cam for the punto GT ( i have the 1242 spi ) is this the right cam? also what do they mean by a reprofiled cam and a blank cam as there is a big price difference.

No

A re-profiled cam means they take a standard cam shaft, re-grind a new profile onto it. But if you do this, to get a higher lift and longer duration then the base circle has to be reduced (I have some pics at work to help explain this, I will post them on tuesday) which means you will need larger shims to take up the difference from the old cirlce to the new circle. The other problem is you need to get the new cut face re-hardened, but not many 'race engine builders' rate these. For road use I'm sure it will be fine.

A blank cam, or billet cam, is when they cast a brand new cam with an over large cam profile, so when they grind the new profile they can make the lift much larger without having to reduce the base circle, so even though it will probably need re-shimming, it shouldn't need a huge step up in shim thickness.

Cam manufacturers do do the FIRE cams, but not all list them. You can ring up and ask Piper, as I bet they will have one or two profiles you can have. Most are ground to order.

I have spoken to Dave Newman at Newman cams, they see a more approachable company, they can make cams to order too. He did give me a price, but I can't remember it now, was probably in the 200 to 300 region.

Or if you are really serious, they can make a cam to your own profile, but unless you have several years engine design under your belt, best left to the pro's.

There has been a bit of talk on another forum about giving an existing FIRE cam to a cam profiler for them to 'copy', which i'm not sure i agree with, but it would mean you could get a C&B cam done in the UK without a 6 week wait getting it from Italy.
