My 04 Rosso Scuderia project update and hyperflow dyno (lots of pics)

wow
do you have highres pics of these?


thanks.

 

The rims are looking great with that detailed red.
Drive in good health and safely..

 

Love the rims......I want those valve caps......Art, where did you buy them from?

 

Thanks Art....will try to get a couple of sets.

 

That car has a wicked stance.

 

Drool.......

 

It DOES look very low.

 

Absolutely stunning!! Congrats on your project.

 

From what I know, CF is not this expensive material!!!

Wondering who dare pricing this mirrors???

 

is it me or is the site not around? can't seem to find it.....

This is the exact look my car is getting right now with MS racing exhaust.
great looking car. congrats

 

Wow!

 

Ouch....

 

+1.......ferrariads doesn't exist.....can't find it either.

 

Thank you for posting your dyno results. Usefull and impressive. Assuming a drivetrain loss of 20%, your 17 ft/lbs of REAR Wheel torque translates into about 21 ft/lbs at the flywheel. I'm very suprised you got that much. Let me explain why.

If we can believe the ONE and ONLY published dyno by Hyperflow on a 360 Challenge Stradale, they report a gain in flywheel torque of around 36ft/lbs, or 28ft/lbs at REAR Wheel using the 20% drive train loss. Technical reflection on this accomplishment, by Hyperflow, suggests their sports cats generated this power increase on the Challenge Stradale because its exhaust bypass values open at 4500rpms in racemode, thus eliminating backpressure. Porsche gurus will tell you, for example, that installing a sports cat with the OEM exhaust in place cancells out the possible performance gains of the sports cat. In contrast, technical reflection suggests a 360 modena doesn't have the same advantage of open bypass values at relatively low rmps, thus causing back pressure to cancel out HP and TQ gains from the sports cats. Some, like me, concluded this is why Hyperflow never published dyno results for a 360 modena, probably because the HP/TQ gains were so low.

I'd be interested in your take on this.

 

You are wrong to assume there is some type of conspiracy. Simply put, we just didn't have a customer who'd step up to the Hyper Flow challenge. Prior to this dyno, every single customer who installed 360 or Stradale cats claimed a noticeable increase in midrange power -- based on the 'seat of their pants' dyno. I wanted concrete numbers because I'm sick and tired of all the misinformation and sniping regarding these cats.

Arthur (porsche racer) bought the cats from Ricambi with the clear understanding that if they didn't produce the power, it wouldn't cost him one-penny. I'd refund all his money and pay for the re-installation of his OEM cats. I paid for the Dyno time, but was not present or involved in any way (didn't want to politicize the results). Bryan Performance Enterprises (Hyper Flow) was not involved in this test or 'deal' whatsoever.

The numbers are the numbers. In an absolute apples-to-apples comparison with identical ambient air temperatures and such, I think the numbers would be even stronger.

 

If I look in the mirror, I think I'm one of those who has moved beyond the misinformation and sniping about the cats. After all, I installed them on my CS. What I'm looking for is MORE information in an imperfect world, so as to deepen my understanding about the cats and their impact on performance. For example;

1) Do the purported HP/TQ gains, and seat-of-the-pants effects come on strong, most noticeably, when the exhaust flaps open, meaning back pressure is eliminated. If so, this would take place on a CS at 4500 rpms in race mode, 5500rpms in normal mode. Not if/when the exhaust flaps open in a 360 Modena or Spider, but assume it would be closer to 5500-6000rpms, thus delaying full performance impacts. On the track, this question is not paramount on the CS, for example, because one can imagine being above 4500 rpms almost all the time. But it is paramount if one is anticipated full seat of the pants effects at launch.

2) Is there a possible loss of low end torque with sports cats, like Hyperflow, because the sportscats (even with OEM exhausts in place) still reduce backpressure somewhat, and this loss might undercut power at low rpms. On my CS, I have no doubt the Hyperflows kick in significantly at high rpms but I'm inclined to reluctantly agree with some other CS owners that they introduce some loss of low end torque.

3) Do additional complements, such as BMC filters make any difference. ZR auto, in Calgary, with a full complement of ferrari's including F40 + Enzo, informed me "can't hurt but not necessary with Hyperflows".

4) And finally, why do other outfits like Fabspeed and Larini deprive us, the interested clients, of the dyno results on their sports cats. They claim HP/TQ gains, yet, for all my searching I've never found dyno results. I'm not suggesting they are misrepresenting or lying about their product, just querrying why they contribute so little to our empirical knowledge. In BMW world, for example, Dinan contributes tons of dyno info. on their products which is fun to mull over as a performance-motivated consumer. Porsche tuners do the same.

Now regarding the weightloss attributed to Hyperflows, no contest, shaves off 14lbs. With regard to sound effects on my CS, no contest. 25% louder at idle, and seemingly new, intoxicating whip-cracking noises while shifting under full throttle.
