Capristo Headers Only

The Capristo exhaust system clearly works very well as well for the Scud and in the same proportions as it does for the F430.

Look at the improvement on the dyno I already posted before. This is the dyno of the best stock Scud Capristo had tested. The increase of torque is really important, from 468.5 Nm to 506.0 Nm (+37.5 Nm) and 306 HP to 331.7 HP (+25.7 PS) at 4500 rpm.

I'm not really looking at the graphs, I have discovered many times in the past in many walks of life that simply looking at figures in isolation and then drawing conclusions is at best tricky and more usually flawed. I have no knowledge of the test conditions, the cars used etc etc so it's impossible to rely on the figures in isolation.

My whole point of contest with your conclusions is not to do with any increases you are seeing with your own cars performance but rather to do with the conclusions you have come to with regards to standard 430 and standard Scud. One of Ferraris stated goals for the engine changes made to the Scud was to improve the performance across the entire rev range, this is published and confirmed at a 10% increase of torque on low to mid range revs and 4% at higher revs. This improvement in low to mid range drivability is bourn out by independent reviews and many owners experience.

You on the other hand, based on some dyno tests from an aftermarket exhaust manufacturer, (high quality products I admit) are happy to dismiss this totally and conclude that Ferrari not only missed this goal of increasing low to mid range torque with the Scud engine, but that they actually decreased the torque in this rev range for a very small increase just at the top end - this just doesn't stack up when you review all the information and look at the changes made to the engine.

The only conclusion can be that the figures you are are looking at are in some way flawed or the interpretation is wrong.

 

Hi Stef,

Sounds very cool; as I have my F430 only little over a month I have the impression I should change to Capristo asap? My car is dec 06 so will have the mk1 stuff and will break one day or the other if I understand correctly (I'm not into car tech stuff sorry).

What is the price of this switch including installation at their site? I'm not that far away from the factory.

Thanks,
-Peter

BTW: I don't need the extra HP.. standard is fast enough for me but I would like to avoid to have high costs later on due to not have changed them..

 

Hi Peter,

If you still have the MK1 headers (please check the service records with your dealer), you are very exposed to the failure of those headers. Mine failed after 3 years the first time and then 3 years again the second time. It's not always easy to know what is the condition of your headers without removing the big underfloor panel (burned area of the headers as shown on my previous pictures). I would not take the risk knowing that faliing headers can have serious consequences on the engine as shown in some other threads here.

I would advise to go for the Capristo Headers + Exhaust brackets and you'll be save for the lifetime of your car It's not cheap, I agree, but I don't try to save money on such important parts of the F430. These headers and brackets are really good value for the money and exceed largely any other solution including the stock MK2 headers (which are very expensive too).

As an extra, you'll save even a littlle bit weight on your car because the Capristo headers weight 4.5kg each instead of 7.7kg each for the stock headers.

To get an offer, I suggest you write an email to Martin : [email protected]. You can reference myself and hopefully, they'll make you a nice offer

Just for the record, I recall that the Fabspeed cats are 200 cell so if you have replaced the original 300 cell cats with the 200 cell ones, you will definitely find that the 200 cell give a bit more power.
The white dust blowing out must be from defective headers not cats.

 

Sorry Russell, but what you wrote is wrong again...

Official published figures from Ferrari :

F430 : 465Nm at 5250 rpm
Scud/16M : 470Nm at 5250 rpm

That's only a 5Nm difference with is nothing and certainly not 10%.

As I said already, the Scud is only faster mainly grace to the removed weight, improved F1, reviewed suspension and geometric alignment including stronger sway bars and some other minor improvements.

Many F430 in good condition accelerate well faster than 4sec - 0-100 km/h and are really close to the Scud. Hey, Ferrari needed some arguments to sell the Scud, sold well more expensive...

And the so-called "aftermarket exhaust manufacturer" has a test bench of such high level and so expensive that several super-sport manufacturers bring their prototypes and future models there to be tested out...and this, I've seen with my own eyes, no doubt Just know that Capristo is far from being just a "aftermarket exhaust manufacturer". Many original Ferrari parts are produced in his factory and especially the critical and moving parts like bearings or tensioners. You may have some of them on your car without knowing it This is Capristo's core business which is B2B, the exhaust being more the B2C business...

 

Stef,

A quick but important question, do you get CEL, and do you have the ECU remapped?

Thanks

 

Stef, with the greatest respect I'm not wrong at all and haven't been at any point in this thread - you are continually falling into the trap of quoting information selectively.

I simply doubt the accuracy of your figures as they don't make sense when compared to the known factors of engine upgrades made by Ferrari, testers impressions and probably most importantly owners experience.

Since you have now quoted Ferrari figures and seem happy to rely on them why don't I pad those max torque figures out a bit with the Ferrari factory figures for the low to mid range - which is what my whole series of posts has been about! I've never said the difference in the max figures was more than the 5 Nm quoted.

430
3000 rpm - 350 Nm
4000 rpm - 420 Nm
5250 rpm - 465 Nm

Scud
3000 rpm - 389 Nm - increase of 11%
4000 rpm - 460 Nm - increase of 9%
5250 rpm - 470 Nm - increase of 1%

As I keep stating, it is the low to mid range punch where Ferrari set about really improving the Scud performance over and above the standard 430 with a much flatter torque curve. An 11% improvement achieved at 3000 rpm! They did this by optimising the exhaust, revised pistons, increased compression, revised electronics etc. The extra performance the Scud enjoys over the 430 is as a result of many changes, some small, some large, some engine, some weight, some suspension etc etc.

 

No Pat, no CEL at all after 1250 km. My ECU's are 100% standard too.

All the best,
Stef

 

Why do I get the feeling this thread is one big advertisement...

 

Here's another photo of the new Capristo heat shields.

These heat shields can be wrapped around the stock catalyzer to reduce even more the engine bay heat (in addition to the heat shields of the exhaust headers).

A hole is made in it, protected by a metallic ring, to let you connect the lambda sensor through it.

You don't need to remove the cats to get the heat shields installed, just wrap them around and plug back the lambda sensor.

Stef,

I wonder what would happen with a properly tuned ECU

Maybe you should introduce Mr. Capristo and I.

I'm about to perform a few experiments on my own 2007 F430 spider.

Jim Conforti

P.S. Does Capristo produce a set of sport cats, or not?

 

Hi Jim,

For the moment, I do not consider remapping the DME's. The couple of solutions I've seen did not convince me at all or were not transparent enough as I want to know exactly what maps are changed and to what values. It's a bit difficult for me to get convinced that some real power figures can be improved with remapping without any other compromises. But I'm always open to any suggestions

What kind of experiments are you going to do on your F430?

For sure, Capristo do have sport cats. They are big 200 cpi cats and the coating is done by one of the best companies (Italian company). I keep that as option if my stock cats get weared out (if one day they do).

 

To get down to the facts

I wanted to introduce a F430 of a private owner which has been body-transformed in a Scuderia by Capristo. Here are a couple of photos of the work done. I suppose this owner must be very happy of the visual results

Regarding the engine, the only transformation been done is on the exhaust with an entire new exhaust system : headers, sport cats, the new Scuderia muffler and the new exhaust brackets. Well, now this private owner must be even more happy with the new levels of HP/Torque delivered.

Straight question for you Stef?

Was there an element of discount on your install in exchange for a write-up on F-Chat?

 

Now let see how this Scuderized F430 performs on track.

Here's a video of the well know Nürburgring. The original Scuderia starts driving ahead and puts on full throttle, the transformed F430 is behind and has 2 passengers. They also put on full throttle and we can exactly see on the video that the F430 is approaching very quickly the original Scuderia, delays the braking and passes him easily in the turn. Then the original Scuderia disappears quickly in the mirror of the F430...

And the dyno results speak for themselves The Red line is THE ONE 521.5 Nm at 4163 rpm on a F430 "just" with an exhaust upgrade...very tempting...

My next project !

Not at all. I just think that the good guys should be known better (and I'm a very critical person with high expectations). Very often we buy thinks without even knowing how it performs or how it has been manufactured. I just give the chance to other owners to get to know what's really behind the scenes...and our cars deserve to get the best stuff out there

 

...... straight answer to a straight question! Cheers!

 

Thanks for clarifying Sfef, you can see why people are questioning this thread (via word of mouth) your previous numbers didn't tell the straight truth but were selective in favor of making the product look better in comparison to the Scud.

There is no way anyone will ever know, but, if what your saying is true, thank you for your time.

 

Thanks, no problem. I thought my posts where straight forward and my intention wasn't certainly to be selective. Sorry if that was understood in such way. Maybe these figures are new here on this forum (it's true that I rarely have seen some real dyno results here) but these facts are very well known in the "offline" world. So, I thought it was time to let things a bit known on a larger scale considering that the F430 is now a "older" car But I can see that the subject is still somehow "sensitive"

 

Stef, in the interests of being fair I'm studying your latest posted dyno graphs. I'm not used to looking at these graphs so you will have to excuse me if I'm not fully understanding.

Looking at the top graph which I think shows 5 cars, the purple trace line being for a standard Scuderia and the yellow line for a standard 430? I think I'm reading the key for the colour traces correct? The higher set of traces are the torque and the lower set of traces are HP?

Looking at the purple Scuderia torque trace, I can see the 3000 ,4000 and 5250 peak figures are 385 NM, 460 Nm and 485 Nm respectively. Ferrari factory figures for these revs are 389 Nm, 460 Nm and 470 Nm so the 5250 figure looks to be about 10 Nm above Ferraris claimed figure while the other 2 are pretty well spot on. This max figure represents a 3% peak gain - I guess this would be within factory tolerance.

Looking at the yellow 430 torque trace, I can see the 3000 ,4000 and 5250 peak figures are 395 NM, 490 Nm and 510 Nm respectively. Ferrari factory figures for these revs are 350 Nm, 420 Nm and 465 Nm. This represents gains of 13%, 17% and 10% respectively over factory figures. I would doubt even the most optimistic Ferrari engine builder would expect to get these gains.

Obviously I'm reading it wrong, where is my mistake?

 

Stef,

I have been tuning Bosch Motronic for 18 years and 4 months now - this is why I'd like to talk to Mr. Capristo - there are very few vehicle calibrators that have been doing this work for so long.

(Started in Feb 1993)

If anyone can get more power out of a car - I can.

Of course, it's just "more" power, but how it is delivered, driveability, controlling WHERE the exhaust valves open for each mode (snow, wet, sport, race) - etc.

I don't just do "aftermarket" tuning - I also consult for the OEM's when their bunches of expensive overpaid engineers cannot solve a software problem.

In any case, my plan is to change the hardware (Headers/Cats/Exhaust) on my F430 sometime this summer and then properly remap the car.

I'm also thinking about changing the intake filter boxes, as the current ones are very very inefficient - I've looked at them. The problem is finding a set that is properly done without buying 10 different sets

In any case, I have all of the factory "map" data for the F430, so I know exactly where every single mapped characteristic is, and the scales back to "real world" - I'm happy to tell you what I'm changing and how - as long as you agree to Non-Disclosure.

Jim

 

Sorry Jim, but I'm not interested. I know you very well, certainly not directly, but through several guys specialised in embarked system, I work with... I'm only interested in guys who have a real concrete hardware/software solution on the market and which allows owners to tune their DME's on their own and as much as they want...
