Well, i dropped the car off today, and we'll see what happens. It is having a custom exhaust,by-pass pipes, headers and aluminum air boxes fabricated. The cost is substantially less than the tubi exhaust,headers,by-pass pipes and gruppe m intake. We'll see what happens! | ||

A friend (and fellow Ferrarichatter) recently said, 'You drive the torque and quote the horsepower.' And it's absolutely right... Outright BHP all crammed at the top end of the rev-range is pointless. Honda/Acura S2000 owners will know that their car feels fairly gutless until it hits something like 5500 odd rpm... Performance mods which induce improved throttle response along with increased torque with a flatter overall torque curve make the car feel and drive a lot faster than a mod which solely delivers 25hp extra at 8700rpm... Products like the Gruppe M intake (of which I am a dealer) are NOT about bhp (they can be, if the ECU is remapped in accordance with the vastly increased air pressure these intakes deliver). - they are about Torque.... Someone I know once drove a 355 and 550 back to back and didn't really get the chance to take either car beyond 100mph (which is where the 550 really starts to excel). Despite this he STILL said that although the two cars were probably reasonably evenly matched below 100mph, the 550 FELT a LOT quicker by virtue of the immediacy of its throttle response at all points in the rev range in ANY gear - TORQUE.... that's what it's all about. Edited to say - Jens - I got your email buddy... we'll talk about this at length | ||

Hubert, Lol! Theoretically you are right! Still I just love my car too much! It is finally becoming like I wanted it to be with the Tubi equipment (Pipes, exhaust) and all gremlins worked out (New clutch, renewed transmission etc.) Too hard for me to part with it now or in the near future so I guess Gruppe M better reconsiders their decision not to produce for the 348 Con saluti cordialissimi, Jens Haller | ||

Robert, You got a point with that, I guess. Sadly I just received a mail from Gruppe M (Ultra fast email response, by the way) saying that they are not producing any equipment for the 348. That�s pretty annoying since their intakes looked very good, IMO. Con saluti cordialissimi, Jens Haller | ||

It is not always about power gains. The GruppeM intake and even my chip my add 10hp but the change in the torque curve is what you want. The problem with F355 is the torque comes on at such high rpm, that in ordinary driving we don't ever get into the cars powerband and we think it is underpowered. Chips and intakes can lower the toque curve so you have more power at lower rpms and the car is more responsive and accellerates harder. Total hp and torque in not always the true story--it also is where that power is on the powerband. If you think your F355 is underpowered, go a a twisty road and accellerate between curves and keep the revs above 6000rpm to redline and see what great power that car has. | ||

well i have the price list here and know the president of them so i would like to put one in but i dont like to spend the noney. also no one for the 328. heiko hgparts | ||

Heiko, Perhaps you are right. Let�s wait and see how high the prices are exactly and what they say about power gains. Con saluti cordialssimi, Jens Haller | ||

the systems are avaible for 355 2.7 355 5.2 360 Testarossa the retail price is EUR 4000 so thats about $4320 much money for an air intake but when you like it sure why not. heiko hgparts | ||

Junior Member Username: Hgparts Post Number: 52 Registered: 3-2003 |
well jens 10hp for the price of $7000 plus making the stuff in well to much for 10hp if they are there can tell for sure. well i agree with test pipes and exhaust with kn. but the rest is to much money you have to spent for only 10hp. heiko hgparts | ||

Allan: I have an ECU upgrade for the 355 from Autothority which made a clear difference in both torque and top end hp. It also raises the rev limit to 8,900. The car is more tractable at low speeds and clearly more powerful from seat-of-the-pants impression. Apparently, Autothority originally developed the ECU for some Challenge competitors(supposedly covertly). It costs about $3,500. | ||

Heiko, Very true but what to do if you -like me- already have: K&N air filters Tubi test pipes Tubi Sport exhaust ? Guess then you begin to think about Tubi headers and Gruppe M air intakes to perhaps gain another 10hp! Con saluti cordialissimi, Jens Haller P.S. I agree that these 10hp are very expensive then | ||

hi well i saw the expensive Carbon filter system too but i dont like to sell them to my customers in case you can buy a set KN for $120 and it�s about the same. and you can spent the rest on a exhaust with sport catalyst. heiko hgparts | ||

Robert and Bernd, Thanks for the homepage! Checked out but couldn�t find parts for the 348 at Gruppe M. Maybe I shoot them a mail about their parts for this modell. Anybody know something about 348 parts from them? Seems they tailor each part individually if necessary. Really stunning prices for sure! Makes Tubi equipment look cheap Con saluti cordialissimi, Jens Haller P.S. Sorry for my constant questions... | ||

And I believe they still use Airflow Meters in the intakes | ||

Be aware that there are 8 throttles in 4 bodies--so its not like porting or swapping the throttle body on an american car. | ||

the gruppe m Intake system for the 355 gave Wayne at ( www.nsxfiles.com/stories.htm on left side of page select chapter 50 and scroll halfway down.) a 10rwhp gain on the dyno. He said he paid $3.5k for it so its quite an investment for a small gain. Its still very impressive for just an intake swap though. | ||

I have a 95 F355 with chip from AutoSport Design--they did alot of challage cars. I also have a Tubi and test pipes. I just bought the GruppeM intake from England and will be putting it on in a few weeks. I will let you know the results. If the intake performs half as well as it looks, I will be more than satisfied. It is a beautiful piece. | ||

I hope you post the dyno results Allan...gonna put the 355 on the dyno in about 3 or 4 weeks. Fuchs exhaust, Tubi 100-cell cats and KN filters...expectationful waiting...then we can compare what's cheaper www.car-elite.com www.ferrari355.de | ||

Hubert, Is there a Gruppe M homepage somewhere? Tried to find one one day but couldn�t get the right one since there are dozens of Gruppe Ms around the world which have nothing to do with cars  Maybe I am just too dumb to use internet, too... Con saluti cordialissimi, Jens Haller | ||

Have you looked into any of the gruppe m stuff for the 355; i.e., carbon airbox, carbon door cards, etc. Fujitsubo makes headers, I think. Andy Viscey, I think, brings in gruppe m (you should be familiar w/ him from you NSX days, no?) Anyway, I hope your fabricator knows his ••••, and I hope you dyno each mod before and after. Who's doing the work? Hytech? | ||

Utter butchery! I hope you're aware that these ill-advised modifications that you are planning will not be looked upon with favor by a concours judge. Leave the red polo in the closet. Don't bother un-packing the lawn chair. | ||

Anyone done any experimentation with any performance enhancements on a 355? Tommorow, my car is going into the shop to have custom headers,bypass pipes and exhaust fabricated. We will also look into maybe larger throttle bodies and maybe something with the air boxes. At worst ill let you guys know about the power gains, and if anyone will be interested, the costs will be significantly less than from TUBI or Stebro. |
