Droool. Slurp.
Well, I think you guys have hit the nail on the head with those seats. That might get the best mod of 2006 award.
Each seat weighs 18kg. The idea was to modify the car by keeping everything within the Ferrari family. Even the seats look alot like the carbon seats that came with the 355 Fiorano package. The Daytona trim, while it was not vailable on the 355, is a trim Ferrari has done since the Dino and Daytona. All the interiro trim is a direct replacement for the original, save, thanks to Valence, that it is made from carbon fiber, because the original sucked! The other thing you will see is the CS steering wheel, sourced by Ricambi, replacing the bus wheel that came with the car, which is also a direct Ferrari piece. Bottom line, I just tried to stay as close to the original as possible.
did u get Classic Coach Ferrari in Elizabeth, NJ to build you your X-pipe? cuz I know they were the 1st ones to make it from scratch on one of their 355 challenge twin turbo challenge cars earlier this year
No Hubert we designed and built the X pipe in house. That seems odd that they used an X pipe on a twin turbo car as well. The performance advantage to an X pipe to balance out the engine banks by forcing them to merge creating a scavenging affect. On a twin turbo car the best exhaust is actually no exhaust, you want to just dump it as fast as possible with no back pressure. Also I did not claim to be the first person to use a X pipe on a 355. I looked at the whole system and it was a complete mess. We did not attempt to even modify it but start from scratch using the correct exhaust design and theories.
I appreciate everyone kind words. We have A LOT more coming but planned on holding off until we launch our new website and finish our 430 products.
oops sorry. my mistake. i meant Classic Coach uses an x-pipe setup on their N/A 355 & 360 challenge cars. 95% of the time Classic Coach has to remap the cars ecu's which they do inhouse. goodluck on ur project daniel. when u tt'ing that 360 u said u were going to do in the summer? i got to check it out
great thread, i read everything here with much intrest. Those seats are insane, and those power levels are pretty good too! Nice work, will keep watching this thread
*Slurp* You guys at Harmony got an update yet on those dyno specs? I am anxious to see the rw Hp numbers. Also, u figured a Hp drop from crank to wheels on a 355? I'm estimating about 50-60 Hp due to the accessories (bad) and transaxle (good). That would put your test car around 413 to 423 Hp at the crank, or a 9-11% increase - this is not really that unexpected unless my Hp overhead is flawed by, say, 25 Hp. In that case the total increase would be more like 15%, which is notable. We are waiting, Harmony-guys ...
OK. Now I am lost (again ) There is a great discussion in the technical section about exhaust systems and the consesnsus there is that because the Ferrari V8s have a 180 degree crank, there is benefit to be had by NOT merging the exhaust of the 2 sides. Either the gurus there are wrong, any benefit in an X pipe is perceived and not real, or the result of some other factor such as increased overall flow. I am open to any scientific explanation of this, preferably backed up by evidence either way. Based on the expertise and experience presented in the other discussion, I am inclined towards the third option. Anyone have any hard data such as dyno numbers with and without? This is not to be a flame at anyone etc, just my auditor's curiosity kicking in again.... Thanks, Dave
I can't see how a system that better purges the hot air being expelled through the headers, as the Xpipe has proven to do in race applications, would fail to give overall better performance to any engine. Secondly, even Ferrari goes off kilter in trying to find a better way. The theory applied to the 355 exhaust went as the dodo. The 360, basically the same engine in most respects, eliminated the upper entry point, for the simpler setup you see also in the 430. Regardless, Dan from harmony will post Dyno figures with the Xpipe, which we expect to show between 15 and 20 better hp figures to the original Tubi set up. Many pictures of all the interior bits will also be posted. Harmony's photographer is scheduled to take picture this coming Thursday.
The "other" discussion has certainly provided explanation of why tubi and OEM are certainly not ideal. The tubi sounds good (to some) and that's about it. Having read more of the other discussion and some of the background documents, I suspect that any benefit from the X pipe is because it flows better. My understanding is that anything after the collector is a hindrance to producing peak power and the less plumbing the better. Here's the link for anyone interested - it makes for very interesting and thought provoking reading. http://www.ferrarichat.com/forum/showthread.php?t=124323 Also, the 355 engine is a similar to the 360 in that they are both manufactured by Ferrari, and are V8s. That's pretty much the end of the similarities. The head on the 355 is a Yamaha design, and the 360 is presumably someone else's. You also say that the X pipe is proven to produce more power in race applications? Can you post some more info about this? Particularly, what engines and dyno info? 90 degree crank engines will experience a benefit, but from my (limited) understanding, 180 degree crank engines will suffer. Again, I am not trying to flame or discredit... I am just VERY cynical and do not believe in "common knowledge" or what "should" work. I always want to see reproducible evidence. So, eagerly awaiting before and after dyno results for the 355... Dave
Seems to me that you are answering your own question. More power is obtained from "better flow" which is exactly what bthe Xpipe does. As far as I know, the less restrictive the air flow the better the engine breathes and stretches its legs. That is the intent. It is intuitive. As I said earlier, we will post before and after Dyno tests next week. If our results are not as expected we will be the first to admit that the Xpipe, while very cool looking and sounding, adds nothing other than weight savings.
OK. Makes sense. I should go on record as saying that I have no problem with looking cool and losing weight. My wife agrees I am sure!
LOL! I am interested in this system, especially for the looks cool, sounds cool with less weight feature . Though added HP is key....
