What about boot lid? Sunroof?

If youy want i can make pics of any detail?
The original one weighs 23kg, the Erebuni one is very thick, and weighs 12kg.
I have to use pins to hold the hood, due to regulations in the Danish "Special Saloon" race-series..
(they have to be able to open it from the outside).
If you want your E34 to drive nicely, this is a "must have" item.. +10kg of the front end alone, it helps remove the dreaded understeering of our cars

Is there a Swedish importer of Erebuni?
We ordered through the Dutch importer, and had to wait aprox 3 months for the hoods to arrive in Rotterdam.

--------------------

Please Finn - I would love to see photos of the hood, how it is attached and the hinge mechanism.

The importer to Sweden is Dalhems ,and it takes 3 weeks (apparently!), cost is 8900kr incl post.

Dalhelms mail address for enquiries .....bildelar@dalhems.se

Finn does it fit as nicely as the oem?

It's mine!

I just got the software from split second and will be installing it within the next month or two. I am going to make my other car driveable so I can take as long as needed. There are a few brackets that I'm sure are functional but aren't very pretty. I would probably remake them and I definitely need to come up with a new intake setup on the supercharger inlet. I just got a new job that gave me some new connections. I've talked to a couple people about possibly reproducing the parts when I'm done woking out the bugs. It would be a while and nobody is real excited about very small batch work. I was installing an active autowerks supercharger on a M-coupe today and was impressed with the size of the rotrex supercharger. It would be much easier to package on the M5 and it has it's own self contained oiling system. Maybe after I figure out the tuning on a kit I know works I will see if one of those is a possibility. I'm sure nobody wants to wait that long but if a potential manufacturer saw that they would sell more than 4 or 5 they would be alot more likely to jump on board. I will definitley be documenting it with photos and will let you guys know for sure when it runs.

I think itd be tough to find someone other than like a shop to make the setup because you have to consider how few of our cars there are to begin with, then how many ppl would actaully want the s/c. I know I would, but not for as much as theyd probably charge (im guessing like 5g) not to mention i wouldnt want to have to build my motor.

I was more talking about manufacturing the parts. The main ones would be the mounting bracket and the intercooler. The intercooler would not even be that hard the mounting bracket would be the most difficult to reproduce. The rest is readily available parts and some welded aluminum tubes with easy to come by silicone hose connectors. The part stopping the easy commercialization of the kit is that all the tuning of the engine has been done with a split second psc1 which intercepts sensors signals modifies them and then forwards them to the engine control unit. Most people would expect a quick plug in. Most people can't tune the engine management themselves. As far as building the engine you should read the website they posted about the supercharger install. I believe the results were nearly 130 hp gain with no internal engine modifications. Most kits do not require mods. It all depends on the amount of boost you decide to run. If you can buy a bolt on kit for any car for $5,000 count your blessings. The kit I mentioned I was installing is going to cost him nearly $15,000 before he is done.

thanks Finn, Carbon fibre has a lovely finish to it. Makes you cross eyed.

15000 for what? The s/c unit probably costs $1000, and the rest is just custom piping etc. I suppose if you have a shop do the entire install 15000 would be about right. And do you really think adding 130 hp to the stock already high strung engine is good? It might work, but for how long? My engine has about 125k miles and I wouldnt want to put that kind of stress on it unless I wanted to kill it within the next year or two.

Listed price for the kit is $9400 on AA's website. He purchased it himself and brought it to us to install. Installation time is somewhere between 15 and twenty hours. I agree there is not a lot of expensive parts but the kit comes with an intercooler, all the custom pipes, brackets to relocate parts, an electric fan, a new intake plenum with blow off valve, the supercharger which has it's own oil system with a reservoir and cooler, a new mass airflow sensor housing, a set of injectors, a set of spark plugs and several hoses and hardware. On top of all that someone is charging you for engineering and at the same time trying to make a profit. Since nobody wanted to do it for our cars I figured maybe I could get the hard parts made for someone who wanted to engineer it themselves and use my car as an example.

I believe the power was made at really low boost levels and as long as the mixture is kept correct it shouldn't hurt the motor until you exceed the physical limitations of the hard parts in the bottom end. I personally am more concerned about the rear suspension strength and will probably see what I can do about it. I can understand why you wouldn't want to modify it to that level I'm just willing to go through the hassles for the power. That and I'm one of the sickos that enjoys the work more than the results.

I heard that erebuni parts were terrible and I didn't buy them. Are they decent parts that use all the stock mountings or are they crap.
