: Funny JZ, I drove one of the first ERT 540 SC cars, picked the car up right from Hugh Plumb. Yeah, I guess driving a 540 SC auto 2 and 1/2 years ago , means less than your few phone calls. I saw the whole installation and know of the problems that can arrise. I was in touch with G Power, H & H and MK Motorsports 3 years ago when you knew nothing about BMWs or any of these companies. I've got no problem with Dinan quality, it's just that their prices are too high for what you're getting. I guess you also don't believe the guy who actually had the white dinan supercharged 540, who wrote into the editor last month and complained that the car was in the shop more than it was in his hands.
: The supercharged 540ia that I drove was not all that impressive. A centrifugal supercharger design is not that efficient. It doesn't make boost until high-revs, not the characteristics needed for a low torque V8. JZ, have you ever seen a supercharger kit completely dismantled? No didn't think so. If you had, you'd realize that there's not a ton of engineering to it. Most of the engineering is in the supercharger head unit, which Dinan, ERT, RMS, H&H, etc.. have nothing to do with. If you call cad-cam'd brackets superior engineering, the more power to you.
: On the dyno with Garrett software and a remus exhaust, hi-flow cats, the car was putting out over 420hp. (not at the wheels, at the wheels approximately 370hp)
: That's it for now. Please respond JZ with your fountain of knowledge. Remember I'm the one with a team at the Nurburgring on Sunday, not you!
hey i finally found a guy who drove an ERT 540i. Congrats, and if the product is so great why dont you have one installed on your car which is??????
The article you refer to is in front of me right now. The original owner who was obviously clueless sold the car. The new owner loves it and yes it is dependable. Why would you even bring up the E34 story and not tell the entire story. I refuse to stoopp to your level of insults, but I will tell you that my garage has been really nice and full for some time.
. JZ, have you ever seen a supercharger kit completely dismantled? um-----yes probably 10-15 kits in total, either in the box or installed. Actually Im working on a twin turbo mod that would use the Bently's parts, but your right it takes no R & D, and BTW Dinan hasn't relaesed the sc yet becasue it isn't perfect, and Steve won't sell it till it meets his criteria.
you said,"On the dyno with Garrett software and a remus exhaust, hi-flow cats, the car was putting out over 420hp. (not at the wheels, at the wheels approximately 370hp)"
I would have to say that a exhaut system with hi-flow cats and software would get you about 10-15 hp maybe and thats if you were driving a really resrticted stock system like the one that comes on the M3. The 540 has a superior exhaust system stock. I did repalce the muffler with a ACS system, i have all the stage 3 Dinan components, and I can't get 370hp to the rear whell like yo claim you got from just 3 mods. Your smoking some bad stuff. Or maybe its the air in Nurburgring. I'll post the article you so galantly point to if you would like, but everyone here has read it. NOw what???????
