928 wing mods
I caved in to family pressure requesting that I keep the car "what, are you nuts?". The car will not be sold. If it is ever sold it will go to my family. My nephew called and started crying. My sister offered one of her garages for storage. I also received a number of PMs from folks who twisted my arm to keep her. Thanks guys!
The 930S will become another project car. I'm going to need a bigger house or at least another garage.
Two Porsches are always better than one!
[Though it is a difficult decision I am going to move on to a new project. I have been influenced by the dark side. I test drove a 1988 slant nose 930S today. It is lust. It is 2900 lbs. It puts out 450 HP with the simple bolt ons. Some of the DP 935s are producing upwards of 835 HP. Very few production cars to date even comes close. It feels like a go cart on steroids.
Porsches are project cars for me. They are toys that I love to tinker with. The 930S offers a fantastic range of variables for a performance nut. This is what I'm looking at:]

This 928 has been a great car. Now that I have it sorted out it is time for someone else to enjoy it. They will get a car that offers performance just short of an SC or Stroked car. I will post again when I determine how much I have in this beast and what is fair.

Hello Curt,
Here is a general grocery list of whats in the car:
928 S4, 1989, VIN = WP0JB0923KS860730, LIC = 3HZM491, Dark Blue
Modifications
1)GT cams – Indexed +3 degrees advanced: Hergesheimer, 7/10/2002
2) 968 intake valves and seats: Hergesheimer, 7/10/2002
3) Kirban rising rate fuel pressure regulator: 928 Specialists, 12/11/2003
Performance set = 47.5 PSI, Smog set = 48.0 PSI, Stock air filter
4) Ott X pipe, DynoMax, and Random Tech CATs : Ott, 1/15/2005
5) Auto trans rebuilt for delayed shifts, w/ AMG gears: Angels, 10/7/2004
6) Devek aluminum radiator, 75C thermostat: Hergesheimer, 1/08/2003
7) Devek aluminum belly pans: Hergesheimer, 2/21/2003
8) Troutman cross drilled rotors: Frank’s Motorcars, 11/1/2001
9) Bilstein shocks, Blue: Frank’s Motorcars, 11/1/2001
10) Custom Autothority chip set: 11/19/2002
11) Powder Coated intake manifold, new seals: Hergesheimer, 7/10/2002
12) Kick down bypass relay and switch: Frank’s Motorcars, 11/5/2002
13) Urethane Sway Bar bushings: Hergesheimer, 2/21/2003
14) Custom Powder Coat valve covers: Exotic MotorWerks, 5/20/2004
15) ProWest Converters, Performance torque converter, 2200 RPM: Precision MotorWerks, 10/7/2004
16) Enkei RC-5 Racing Wheels: Turbo Performance Center, 8/3/2004
Front = +54 mm offset, 8.5”, Rear = +60 mm offset, 10”
17) Michelin Pilot Sport Rib, 225/40ZR-18, 285/30ZR-18: TPC, 8/3/2004
18) Erebuni 020RW Wing, 56” W: Erebuni, 12/27/2004
19) Leather Dash / Pod Cover: Jager Engineering, 8/3/2004
20) Wet Okole Neoprene Seat Covers: Performance Products, 8/12/2003
21) Kevlar Spare Tire Cover: 928 Motorsports Inc., 9/3/2004
22) New Porsche Timing Belt, replace CRP: Precision MW, 5/18/2004, 110842 miles
23) Custom Blue Carpet, fitted: Geisens Automobile Upholstery, 12/30/2002
24) Custom Auto Cross alignment: Rocky Tussey, 5/25/2004
Updated: 2/17/2005
Notes: 1) Stock air filter provides best performance W/ fuel pressure set to 47.5 PSI, no vacuum at idle, or 55.5 PSI fuel relay jumpered, engine warm.
2) K&N air filter provides best performance W/ fuel pressure set to 51 PSI, no vacuum at idle, or 59 PSI fuel relay jumpered.
3) Stock fuel pressure = 48 PSI, idle, no vacuum, 55 PSI fuel relay jumpered
Addendum
1) Smog for CA: In order to pass emissions with the Ott X pipe, Random Technology CATs, and DynoMax mufflers the following configuration is required.
a) The engine must be in good running condition, fuel injectors, O2 sensor, MAF, CATs, no vacuum leaks, stock fuel pressure = 48 PSI (vacuum line off RRFPR for setting), normal compression, clean spark plugs, new air filter.
b) The stock chips must be installed in the LH and EZ controllers
c) The air diverter valve is turned off by placing a plastic ball in the vacuum line but the air line must be connected to the X pipe in order to pass visual inspection
d) Verify: The AFR at 2000 RPM will measure 14.3:1 with the O2 sensor bypassed as measured with the O2 sensor removed and a Lambda probe installed. The engine must be hot during this test. IR temperatures will read 400F at the CAT inlet and 500F at the CAT outlet. This verifies that the system is working properly prior to the smog test.
e) The CARB certification for the Random Technology CATs must be in the glove box with the registration at all times.

It's becoming evident that power to weight ratio is more important to me. (my) 928: 420 HP / 3600 pounds. 930S: 450 HP / 2900 pounds. DP935: 800 HP / 3000 pounds, and so on.
The heavier car is a nice performance cruiser. The lighter one is a snappy little go cart.

Sorry to see you leave the 928 community. I think everyone here has benefitted in some way from your research and knowledge. Have fun with the new toy!

Steve,
Glad to see you are keeping the 928. What do you think about the Erebuni wing from an aerodynamic standpoint? Would there be any way to get 5 more degrees out of it? I'm thinking about calling them up and seeing if they still have one available, as $225 is much better than the $600+ for other setups, but I'm still on the fence as to whether it would be a good wing for a track car.
