GruppeM Carbon Airboxes for 355/360

I posted a thread last week regarding the use of MACARBON air boxs. They are sponsors on the board and need some feed back on there product. I love the GRUPPE M INTAKE but not the price point. The MACARBON is $1300 less then half the price. I have alot of experence in after market parts and yes there are huge $$$$ payed for Brands that sometimes are over priced.Your opinon....BEN

 

I have had the GruppeM air box on my 95 F355 for two years and I can tell you it does add power. I am not sure that the MACARBON has the same K&N filter inside. I saw this same filter on the LeMans Corvette and the Audi's.

 

Being able to deal with Gruppe-M USA extensively I learned a few things about the company. The quality, craftsmanship, and the time spent on these units are well worth it's value. I understand products like the MA Carbon intake covers are 1/2 the price, don't get me wrong, John has great products, but the Gruppe-M is a complete unit. The full replacement, with heat shield, and new K&N Air filters. Gruppe-M is also K&N Japan, and that wasn't just because he has the money to do it, but it's because K&N felt that their product and his worked well together. I've seen them on the 355/360/Gallardos/M3, and never once has there been any problems with them. The quality and fitment is unlike any other. The only bad thing, is the instructions are in Japanese, LOL. Regardless, I will continue to support the product as long as it's available here in the US. As far as proven test and horsepower gains, I can only say from talking to my customers that they love it and have noticed gains in their own opinions.

 

I am wanting one for my 360 (actually now for 2 of them) both 360's do yo uhave a hook up ?

It won't be for awhile since there is no real USA Gruppe-M now. It's a little tricky. =/

 

I got mine from www.gruppem-usa.com
They are a bit elusive but we worked out a very good price and both units I have ordered were sent out right away. They do have some supply problems from the Japanese end, but once here, are good about filling orders and will work with people.

Dam looks awesome. What actually gives the HP increase. I assume lighter weight. Better air flow??

 

I've heard everything from 8 - 22 HP. Has anyone ever dyno'd before and after? $3,000 is a lot for 8 HP, even though it sounds great.

 

that web address doesnt work..

NAPerformance on this site is/was a dealer but some weeks ago said they weren't available until further notice so "don't request until he gets word they are", or something like that. I'm sure Kevin will check in on this. I'm intrigued for my 355 and will follow them. Esthetics if nothing else..they are gorgeous in the engine compartment..

Stock boxes are not very heavy so its all in the airflow. NO angles, all very smooth inside and a highly engineered structure/shape to deliver non turbulent. Supposedly, they do lots of air tunnel research on their products and really get the flow tuned, reducing turbulence and maximizing flow in the most advantagous current. This is what I was told by a Japanese company rep. Could be rubbish, but I think not, especially if you look at the two side by side. If you blow into a corner, you get backflow and misdirection. If you blow into a smooth curve, you get directional movement. I am no engineer, but just the shape and interior architecture convinced me.

Does this increase the induction sound as well?

 

okay so here goes...

I called and spoke with them in JP 2 days ago, and my unit is being shipped next week.

I wired the funds this morning, and they are getting it built and then shipped.

they said about 3 weeks total..

Not sure what Kevin from NA Performance was talking about or why this is happening this way, but I will have the answer in 3 weeks.

I know of a shop in Hong Kong who sells Gruppe M parts and other parts for the 360 and 430.

I bought a set of CSL wheels for my M3 when they were hard to come by. The pricing was reasonable.

It says on their site the Gruppe M airbox is $2,890. I don't think shipping will cost that much.

I'm not affiliated with them, I just want to help my follow fchatters out.

PM me if you guys are interested.

 

I got the Gruppe M airbox Carbon, with shipping for less then 2100.00

That's definitely a better price than the shop I was talking about. I think some of their carbon pieces are cheaper than other places. I just don't know about the fit and finish, but their M3 parts are good.

Aaron, post pics when it comes in!

 

Here is a picture of GruppeM's dry carbon version...

That looks like fiberglass in your picture, on the inside of that intake. Those GruppeM intakes are certainly 'noticeable' when you open the engine compartment - Visually, do you feel like it dominates the engine?

 

I thought i had seen the brand somewhere... they sponsor a Carrera Cup and GT3 RS in British series'

Website for Europe (at least it is in English )

The appearance & presentation in the pic above is very nice too...

 

I for one dont believe nothing unless you have dyno proven results before install and affter install. For one thing a airbox will not give you 20hp one of my friends has one on his stradale and I drove it. The sound of the air getting sucked in, Sounds like a supercharger its loud and its a sucking sound . The throttle response is better to a certin degree, but did I feel a differance in HP? no way. Even if you pick up 15hp you dont feel that kind of minimum power. Add 30-40hp and you feel that some, Groupe M make a high quality product I think the price is a bit steep but many say buying a NGT exhaust for 4gs is insane also.. The exhaust changes sound no hp thats for sure and for a better sound I think spending the money is worth it..For cosmetics??? To each his own I guess...

Groupe M are really something but until I see dyno results before and affter I don't buy it..

 

I saw dyno results from a car dynoed by Bob Watson in England. He is a well known Ferrari, Lambo and Prosche tuner. It was a gain of 10-20hp in all rpm ranges. The torque curve was also better for low end torque. Contact Scuderia which I think is a sponser. He sent me a dyno sheet before I bought mine. Don't just look at maximum hp at 8200rpm but look how it changes hp and torque at various rpm. What do you think that better throttle response that you are feeling is? It is an increase in torque and hp at lower rpms.
