Ess n52 supercharger!!!!
 

So I have been following this over on e90post under the non-turbo section. Finally, there seems to be a legit company willing to help all of us with the N52 engine. Check out the link and Roman at ESS seems very receptive to questions. Click here.

I plan to wait about a year or 2 and see how people are doing with this kit before committing to this purchase. I currently have 70,000 on my 2007 530i with SMG transmission. I was already planning on keeping my car till 200,000 or more but this has just reassured me on keeping my baby forever. Hopefully all the other n52 owners on here are excited about this as well. The cost seems to be ~$5,000...which isn't that bad compared to some of the other kits out there.

Pretty cool.

Side note- I had no idea the SMG tranny came on 530s, I had only seen it on M5/6, 545, and 550 I think

yup they are rare, but there are at least 2 other members on here who have the smg with the 530i.

ARMA SPEED

What about these guys?

^ I have not read any threads on the few BMW forums I frequent with anyone using the ARMA superchargers. ESS has been around for a while and has a great reputation...My friend had the ESS supercharger for his e46 and it was amazing. Let me know if you find any information on ARMA speed supercharger buddy!

ARMA DO NOT OFFER ANYTHING TO INCRESE POWER for out N52 engines..

Actually, they do. Here's the link to their N52B 2.5/3.0 Supercharger kit...

Hey guys here is an update for you. I did not have final info to release until just this past week as this product has been under heavy testing and many changes. We have revised our stage 1 kit that we have just started installing in house. Pre-order kits are shipping this week and retail sales will begin in about 2 weeks.

Changes have been made on the first release kit. The changes include slightly less boost and lower retail pricing. First the stage 1 kit will make gains over stock of about 60 whp. The new stage 1 will produce 5 psi and will use stock fuel injectors. Retail pricing will be $4,495.

We will later release a stage 1+ that will run about 6-7 psi, use upgraded injectors and make around +80 whp over stock. The retail on the stage 1 + will be around $4,995 and stage 1 customers will have the option to upgrade which will be very easy to do.
