Fairly easy to install. Have over 1000 miles on it and no problems. The upper radiator hose in the kit did not fit for me. Could never get it to clear puley and fan. Had to improvise, see pic. Manual fan on 530i seems to be noisier, am in the process of converting to electric. Also see pic. Easy to work with company wise. Very prompt in returning e-mails. Manual not detailed enough for amateurs like me.

I'm installing mine now. It is a pain but not too difficult. I had some pulley problems and the SC belt was too loose but overall it is looking good.

here is some info that I put together back in March.

I will also be putting together a review on my ESS system once it is finished. I also have a dyno run before the install and will get it dyno'd again after to measure the %HP increase.

The pics look good...thanks

Have you guys heard anything about RMS superchargers? vs ESS? which one is better and which is faster? I heard RMS was more powerful pushing 8psi vs. ESS's 7psi.

I visited ESS' R&D facility last year and spoke to the owners for a couple hours. They showed me around and explained everything about the kits and the development. I was pretty much impressed with everything I saw and I'm ready to buy their kit when I have the money. I have heard they sometimes screw up shipping and sending wrong/missing parts though. Hopefully it's something they're improving. In terms of the quality of the kit it looks top notch, and they are partularly good with ECU programming.

Hope that helps,

I ordered an E36 M3 kit for my E36 M Coupe. I knew it would not be an exact fit. ESS told me that others had installed this kit without excessive problems.

My big mistake was sending in the ECU based upon their promised ship date, rather than waiting until ALL the parts arrived before sending in the ECU. I was without the car for a LONG time waiting for parts.

If there is an extention cable for the MAF meter, you DO need to use it as it contains a resister in one of the wires. (Feel it and you'll detect it.)

If they forget to send the manual, INSIST on an e-mail of the full manual, not the wimpy two page one.

I feel that the company is basically honest and that the product is good. However, take promises of actual or forecast ship dates with a grain of salt the size of Delaware.

I had trouble getting the car to idle smoothly. The problem was a combination of a small intake leak (intake manifold seal) and the missing resister. They offered to have a mechanic come to me. (I don't know how long this would have taken, but they offered.)

They are very prompt with e-mail and answer the phone at hours that are very late in Norway.

The search section of roadfly blows but DTM and bimmerforums have good info.

Search for RMS* or supercharger

I also will be dyno'ing my 95M3 with an ESS kit in about a week. Ill post a big writeup with installation pics as well as dyno pulls etc.

Baby\'s ESS unit has some install issues. The AC bracket was for a Euro AC compressor which has a larger radius than the US AC compressor. VAC had to remanufacture the bracket using my original one. Also VAC had to machine the ESS compressor bracket to permit the AC high pressure hose to run along side without being kinked. There are pics on Baby\'s CarDomain website.

One thing I will say is the ESS ECU programming is spot on. Seemless and it is as if BMW put the SC there in the factory.

One last note, and I am not sure if it is a design issue or a bad belt, however, during the One Lap of America, the ESS internal belt broke somewhere in New Mexico. As a result we had to compete in normally aspirated mode and we fell from 27th overall to our eventual 46th overall. If the belt breaks on Tuesday at Pocono (long course),.....Vortech V2SQ

My install was a bit rocky with all the problems revolving around the ecu. First, problems with drivability, then check engine light with many codes relating to lean conditions. They then sent upgrade consisting of new injectors and new MAF meter and new chip for ecu.

When I got the ecu back, they had installed a chip programmed for an auto tranny, so the car ran terrible. After many angry e-mails, I finally sent the ecu back. They returned it admitting only to a problem due to my car being manual. The car now runs fabulously but after 50-60 miles, the check engine light comes back on after resetting it by disconnecting the battery. I am now in the process of trying to get the codes out to see where the fault is.

It is a good buch of people and very good product, but support is very slow and your car is down for long periods! They are still working kinks out of US spec cars, at least with the 4.4, although I have heard that the I6 are ok.

I'm lookin' to buy an ESS for my 328i... sounds like the kits are improving? At present, they only offer a Powerdyne for the E36 328i... is it worth the extra $900 to get a Vortech? I don't race on tracks, or do much street racing, I just want the extra Oomph, especially at highway speeds (IE passing)... thanks,

Minor install problems due to very high level (poor ?) instructions. It was a DIY install. Car was down 2 weeks. Engineering seems very good -- business side is very bad. Support is OK.

Would I do it again ? Maybe. The power increase was great. The hassle factory was high ...<br>- Paul
