ESS supercharger for 540i

[andyman32]

I'm thinking about trying to put together the cash for an ESS supercharger. I already know that in order to reap the benefits of 410+ hp, I'll need bigger wheels & brakes... which adds a few grand to the operation.

1) Any suggestions for good places to find BMW wheels for relatively inexpensive? Has anyone had any experience with aaarims.com?

2) Is there anything else I should need to upgrade under the hood at the same time as the supercharger?

Thanks!

Under the hood, yes. Usually the kit comes with bigger injectors, maybe a fuel pump and pressure regulator. Also new software for it. I would be more worried about your transmission, if it's an automatic. If it's a manual, lightweight flywheel and HD clutch. I am a bit more careful about power on my car b/c now that i've toasted a transmission, and also found out the car is driven entirely by rubber. (yes the dual mass flywheels are connected by rubber) I am sure you can find a way to build up the automatic transmission to handle the extra power. Also have you installed better suspension yet? I would honestly make suspension, wheels, and maybe the 750/850i brakes for the front the first modification before the blower.

Not to hock my wares, lol, but when/if you decide to go ahead with the ESS SC I carry them so give me a ring/email. I also own a 95 540i 6spd so we're kindred spirits too. I can also help with the brakes.

How much does this cost?

[Tiger]

5HP30 tranny are very robust... even the V12 BMW engine uses this tranny... not to mention Rolls Royce too that has 500HP engine.

[andyman32]

Ya think so? It would be serious sh!t on a sh!ngle if I spent $5k (retail cost of supercharger) then burned out a transmission a few weeks later.

Nick - thanks for letting me know. If/when I do this, I'll give you a call. Unfortunately, my tranny is the 5HP30... auto. :-\ I'm almost thinking I might keep this one as my DD, then get another 540 w/ a manual as a track/project car.

Anyhow, I've been convinced to work on other things first... sport suspension, bigger wheels, bigger front brakes. Oh and I need something else for this project... MONEY!!! Thus far my horticultural project (money tree) has been unsuccessful.

Ask around... you will find out why BMW used 5HP30 tranny... I think it is the strongest tranny from ZF at that time.

[tim s]

he told me the 5hp30 was overkill in the 540i/a. it's like having the allison tranny in a truck. this tranny was used in:
austin martin DB7 ( 5.9 liters, V12, 420 hp, 400 ft-lbs. )
Bentley Arnage (6.8 liters, V8, 400 hp, 619 ft-lbs)
Rolls-Royce Silver Seraph (5.4 liters, V12, 322 hp, 361 ft-lbs)

i got the car list from a 5hp30 pdf from zf's web site & i got the car specs from edmunds.com .
