Just had the car's already modified mapping adjusted to account for the mods i did in the past year. Here it goes:

205wbhp:
-I have to scan the dyno chart as i only have it printed
-Car had only CF2 manifolds with equal length downpipes

226wbhp one:
-Full decat with CF2 manifolds, equal length downpipes and big silencer in place of secondary cats
-X-air sports air filter
-Cold air feed from feeding from front bumper
-Remap

240wbhp one, in addition to the above:
-Ferrari 360 throttle body
-ACT carbon plenum
-Crankcase ventilation removed from intake
-Tuned remap

Same dyno.

Pretty good gains with the plenum and 360tb then!! I need to get mine on the RR to find out what mine is since I've got her running properly :)

Need to sort out the air intake though as in struggling for air once you get into the upper reaches of the rev band :lol:

just with installing cf2's and airfilter mods, you don't need the remap, correct?
I read that you did, squadra allways tells that changes on exhaust or intake do not need remap.

It is needed to start utilizing the advantages of the TB.
Or am I missing a point?

I have cf2's, 360tb, equal length downpipes and havn't had it remapped. Neither did Silvervalver for a long time.. the ecu does adapt very well in most cases. I think silvervalver had 274bhp and then after remap all they could get was 277bhp? I could probably unlock a little bit more performance with a proper map, but it runs very well as it is.

Well, the calculated figure is just that, calculated based of the actual measurement at the wheels. Could be useful for pub talks though :)

Bacon, what's your intake setup as I remember you saying you've got carbon plenum and big TB, you using a CDA? And could you take a pic or two how it's fitted etc please :)

As Fewleh mentioned, the 430tb requires a new intake pipe as the standard one won't fit over it, a new plenum too as it is wasted on the standard plenum and also a remap.

You'd be looking at around 1.5k at least to have it running spot on :)

the 360 just plugs right in and oem air intake will even fit over it (just about!).

the 430 is obviously bigger and someone else can tell you more about it, but think you need to get an intake hose that fits over it.. I think maybe the size means you more likely to need a remap and stuff to get it running right..? but someone with 430 can confirm this

Nice one Scociu, that really is a special motor you have there. Add all the interior mods/retrimming work, and the re-trimmed seats, and it's a total package that most can only aspire to. Hat's off to you for continuing to do more and more to the car.

Two things really stick in mind from when I saw your car, how free it revved, and odd but true, the smells from an exhaust system free of cats - fantastic!

Hi from Spain, I finished my 156 GTA Evoluzione, the car has this mods:

Plenum ACT + TB Ferrari 360 + equal lenght pipes + exhaust manifolds Alfa GTV V6 + exhaust supersprint + anti roll bar eibach + coilovers BC Racing + OZ superturismo 18" + front and rear strut brace + front ram air.

the results before remap was 241 CV and after 274,05 CV. I´m happy with the result.

Hi It´s a bit difficult to explain to me in English, but I´ll try it, I put a T in both engine exhaust outlets with a pcv valve as like the original system but instead of return the vapours to the engine, they goes to a catch tank with air breather .
The system is the same as the original but the oil vapors used not return to engine, In the engine, the air intake aspirate clean air and the oil gases going to the exhaust and the rest to catch tank and the atmosphere.
I´ll post pictures for explain.

This is what we have bought with Gotcha from this UK manufacturer - Home | Rutland Motors. And how it looks properly installed by Gotcha you can see on the first picture. I had to remove mine as had some disturbing whistling noise going out of pipes and did not have time to fix yet.

The second picture is a 3.0 V6 I have bought from a 166. Notice that this engines were fitted with an OEM catch tank out of factory with a line entering back to the engine at the back of the block - could be seen on the third picture just next to the exhaust manifold port.
