Colombo Bariani cams?

Ok guys !!

I was thinking of fitting a supercharger on the car, but I cannot trust the reliability especially that I use downshifting alot instead of breaking ..

I ordered my exhaust from gazzella and i loved their service, now im thinking of getting the Colombo Bariani Performance Camshafts. Any thoughts on that ?

Yes/No ?

If yes, which ones shall i go for ? Medium Profile / Upper Medium / High ?

Without programming ? how much shall i expect when/if i dyno the car?

Thx in advance ..

Re: Colombo Bariani cams?

why would there be issues with a supercharger bouncing it off the red line or downshifting?

I drove the latest XKR (twin supercharged 4.2) recently, that has no issues downshifting instead of braking or being bounced off the redline.
Personally I found use of the middle pedal and downshifting more effective than just dropping a cog in the XKR, somehow it seemed to slow quicker for the corners?

anyway, for the cams, they will need setting up on vernier pulleys whatever you do...

What Jasons said about the Verniers, unless they come with specially made camlocks (I doubt it)

Re: Colombo Bariani cams?

not a great idea to fit without a remap either, the ECU will think WTF is going on and you prob won't feel much of an improvement TBH unless you map it

Oh, and high lift cams tend to like higher compression ratios, these tend to compliment each other.
(such as the 12v leafs, higher lift cams and higher c/r gave the majority of the mechanical power increase, and a remapped ecu to suit)

Theres no point and no real need for fast road cams fior boosting a twinspark engine.
Read his post again...

He is not fitting fast road cams and supercharging.
He was looking at supercharging but is now looking at cams instead.

3.2 ..

yes only road use, someone suggested the upper medium profile because the max profile will cause some kind of trouble in traffic something about lacking torque i guess .. ?

but then again, is it worth it considering that its also less than third the price of the supercharger ..

Re: Colombo Bariani cams?

you loose bottom end if you go full race cams, you'll have to rev the nuts off it just to roll it

Re: Colombo Bariani cams?

Even their Road Max cams (AR24.ST1), don't look too wild. But the amount of lift on the inlet cam means changes to valve springs (they say just removing a lower washer) but that still means the heads need to come off.
If you don't want to get into removing heads, the Road Medium AR24.SM2 look to be usable. Inlet valve lift is higher than the lower spec AR24.SM1 but the duration is slightly less.

Very difficult without actually trying both!!
It would be worth contacting C&B direct. They must have run the cams at some point so should be able to give some advice.
