I'll edit the list as owner information is submitted! Having a registry thread will keep the owners in touch and together we can share specific questions/problems/solutions with the supercharger system. Hope to hear from some of you guys, for additions, changes, corrections, or even if it's a simple hi!

Here's a few threads with related info.

Dinan/Vortech "S-Trim" and "Si-Trim" impeller blade upgrade information
Boost/Leak pressure test
Dinan S/C: vacuum hose routing block diagrams

If anyone ever needs the entire S/C install manual, I have it on .pdf and would be happy to e-mail it to you. The file is too large to attach here.

Attached is the DigiKey data sheet for YAGEO resistors. This is the 0.6mm leg, 1/4watt, 1% tolerance resistor that Dinan uses in the R4 position of their Turbonetics T9 box. After my Si-Trim impeller swap, I read 4.39v with the previously installed 221 ohm resistor in the R4 socket (Dinan install step 234). I changed to a 205 ohm resistor (next resistor size down in the Dinan D443-0932 resistor kit) and read 4.67v. I then reverted back to the 221ohm resistor. Math say that 213ohm resistor would get me really close to the Dinan recommended 4.50vdc-4.55vdc.

As you can see in the attached .pdf there isn't a 213 ohm resistor. I ordered five 210 ohm resistors (part: 210XBK-ND) and five 215 ohm resistors (part: 215XBK-ND) from www.DigiKey.com (for $3.50 shipped) and that should get me close enough in the 4.50vdc-4.55vdc range.

Here are some replacement part numbers if you guys need to refresh some of the s/c kit parts:

V-2 Si-Trim Dinan spec - Vortech P/N: 2E128-270
Pulley - Vortech P/N: 2A036-048
Pulley key, pulley bolt, and retainer washer set - Vortech P/N: 8R101-001
Pulley key only - Vortech P/N: 7U100-070

Note: Use anti-seize on pulley input shaft, pulley key, and inside of pulley.
Note: Use blue loctite on pulley bolt, and torque pulley bolt to 25-30ft-lbs.

S/C Belt - Dinan P/N: D862-6324
Vacuum hose kit w/ 2 check valves - Dinan P/N: D862-6312c
Bypass hose plug - Dinan P/N: D862-06313
PCV valve, couplers, 8 hoses, check valve - Dinan P/N: D862-7128
Oil return hose - Dinan P/N: D393-0358
S/C inlet rubber coupler "heart" - Dinan P/N: D340-0464nln
Intake manifold rubber coupler - Dinan P/N: D340-0628
Upper charge pipe to air bypass valve rubber coupler - Dinan P/N: D340-0104
All other "normal" round rubber couplers for inlet/charge piping - Dinan P/N: D340-0865
Air Filter - Dinan P/N: D401-0430
T9 MAF clamp box pack of 10 different resistors - Dinan P/N: D443-0932 (I have two resistor packs that I'll give to someone for free if they need it!)
MAF - Dinan P/N: D763-1444
Throttle Body - Dinan P/N: D760-3440A

I have a 2002 X5 4.6. Early on I had all Dinan mods installed other than supercharger taking it to 369HP. Just rolled over 90,000 miles.

I am debating whether to keep the X5 until next fall. If I do so I want to add a supercharger. Question is---do you think it would be worth the expense and increased risk over what I already have?

Is there anywhere to find 0-60 and quarter mile performance of a supercharged 4.6?


Thanks in advance for your thoughts.

Hi BC, SeattleYates logged a gtech 0-60 time of 5.2s, details can be found here: http://www.xoutpost.com/bmw-sav-foru...-s3-wow-5.html

There aren't any recorded 1/4 mile times that I've heard of, so I'm going to bench race for a minute. Bear with me... feel free to correct if I'm off...

~4824 curb weight (spare tire, tool kit, everything)
~149.15lbs of curb weight is fuel (24.56 gallons of fuel @ ~6.073lbs/gal)
(Let's say we race when the reserve capacity is full, in other words, when the gas light comes on: ~2.5gal@~6.073lbs/gal is ~15.18lbs of fuel)
Subtract the difference in fuel weight (-~133.97lbs) and we're at ~4690.03lbs
Driver weight for this instance is ~190lbs
Race weight is ~4880.03lbs
(Peak) Power is ~451bhp

I would bet a few dollars that the time would be very near 13.5-13.6 @ 106-108 mph Maybe a tenth or two faster, given the Si-Trim impeller blade, more area under the power curve. That coupled with the performancegearing 4.44 front and rear differential gearsets would have us knocking on the 12-second door.

As far as expense justification, that depends on finances, which are none of my business.

disturbedk24, just wanted to clarify, is 01blacks4 your old username, or did you buy the Dinan X5-S3 from him/her? Good to hear that another found this thread!

[disturbedk24]

i bought the s3 from 01blacks4

[01blacks4]

he bought it along time ago...i suck at updating stuff! sorry

who knows, i might buy it back though.........

[romeokc10]

I have to give you guys credit for putting a SC on an X5, they are just too fragile in my mind with all the other stuff that seems to break on them. I'll be putting a SC on my C5 Corvette soon, don't think I would ever think about putting one on my X5.

you know you want a toy, you can do those top secret plans you had
