Hi to all!
I have spent some time to compile a 'list' of the various products in circulation by several cam maker...
The propuse is to find the best profile for my engine that I'am making...
(and probably for your also  )
With your aid i already say whot kind of work need to be carried out, but i need one last thing...
This is the list
Cams
I wont an engine with the best compromise for torque at low rev and power at high rev.
If for the choose someone need some other info on the engine that i'am in mind to do, ask 
So, if I also forgotten some maker of cam, say me the link (or the spec) that i include it on the list...
Thanks another time for the patience!

Depends on the rest of the engine spec.
Personally on a engine with std management I would leave the std cams in.

C16VBP285H 2000-7000 14 BHP 264/264 10.03mm/10.03mm 110/110 22-62/62-22

8000.
199bhp is what it made on the rollers, and the rolling road operator claimed it was accurate, and other cars that day made sensible power, but I'm dubious that it was actually that high.
For the spec it should have been closer to 180.

You have skimmed the head by 25 .... what? 0.25mm?
Whot are deseemed rod?
whot difference occour between SBD cam belt rollers and standard one?
Do you have a graph on a dyno?
It pull better than the standard engine on low rpm?
Your engine seem like the one that i wont build for my car! (step by step...)
So standard piston and rods... wow!
I'm very interested :>

Ok
But... another question to put in queue...
With the 4tb setup, not is present the automatic minimun, right?
And... If I wont to maintain the air conditioner? Without the automatic minimun i think that the car will go off...
Right?

Something has been lost in translation, what is automatic minimum?
The deseemed rods are standard rods that have had the seems in them polished out, which should make them stronger.
The SBD rollers are made from proper metal bearings that wont break up and will cope with the rpm better than the std ones that supposidly crack.

If you mean the minimum revs, then stall becuase there's no idle control unit on a TB set up then no, because you set the idle speed with the TB's, they do not shut fully allowing the minimum amount of air passed so the engine idles. Idle control valves are only really needed on cold start up, after 10-20seconds of holding the throttle lightly you're fine and ready to go.

Yes, i mean that! I don't know every english word - sorry
So, when you power-on the air conditioner, the car doesn't stall with 4 tb setup?
Seemed rod means shot peened rod?
Google translator is very ugly
And you use the original f15 gearbox?
Sorry for the numerous questions...

Yes the rev will drop and may stall the engine, but might just try and idel at 500rpm
De-deamsing the rods is removing the seam that run all down the side, and the surface casting finish to leave a smooth surface, as this reduce pionts where stress can build up. Then you need to have them shot peened idealy to toughen the out surface of the rod.
There are different opinions on this, some say you should and others say don't waste the time or money. Miles de-seamed his rods, and I have not, and we've not had any problems.
Yes the F15 is still used, and the standard clutch.

Miles took his to a tuner local to him who made the map for him on a rolling road.
I still haven't got mine mapped fully yet as I'm waiting till I've put everything I want on to the engine. I have done the map I have myself, but it is far from perfect. Have a tuner do it for you, as there are parts you can't do on the road, i/e wide open throttle, without accelerating too hard.

I'm thinking to buy a secondhand unit, or make a megasquirt...
My buget is not very high...
And also to do a 4tb system with 4 moto tb's...
But for now it's only a project, i think to do this with very calm... To distribuite the expenses in the time.
All the job is done in a second engine that i'm taking apart.
The megasquirt is very interesting... I think that is possible to modify it to accomodate the original sensors... Not bad!
But if i find an aftermarket ecu at good price... there is less work to do!
