That being said $3,000 or there abouts for a s4 engine plus a blower setup, even as old and out of date as the one pictured is not out of line, i think its a good deal honestly, even if its just a core its reasonable, i think some of us on the board questioned the integrity of the ad because of the dated picture. I swear, but i could be wrong, but i swear i saw that picture like 8 years ago when i first discovered that 928s4vr website years ago.

The engine shown on my E Bay add, IS NOT the same engine shown in the picture, in this link, the engine I have is stock, no milled pistons.

The super charger looks like the one I bought off of E Bay, that’s why I copy this information (7.5lbs (measured) boost. b) 15 lb pop-off valve (safety from intake backfires). c) Four 90lb injectors, running on top of SC)
I think the seller was Mark. R, I am not sure, maybe Mark can clear some of this confusion.

Clearly you have a pool of knowledge about BIG HP, so if school is in session I am ready to take notes.
Cheers,

The proven method for producing horse power is to pump the most air and fuel into the biggest combustion chamber you can fit under your hood, That’s why super charges and turbo feed motors are kings in the HP department.
My field of expertises is power train, if you what a 928/ A28 (4speed) or a MB 722.3 transmission that can handle 625HP I can build one, as well as the 722.6 Mercedes Benz 5 speed transmissions , 725 HP.

- In 1991, the engine pictured on 928s4vr.com was built by Dave Jarvis of Jarvis Tech 810 Northwest 57th Street, Fort Lauderdale, FL 33309, (954) 776-7962. Some time later, the intake was re-designed slightly lower profile, eliminating the Lucite top piece. It was part of a larger project where they also added a DP body kit to the 1985 928 at the same time. To accomodate their supercharger and intake design, the hood was modified with a 3" bulge, similar to what is seen on drag Mustangs.
- Between 1992 and 1995, Protomotive Engineering ended up with car in some sort of trade.
- In 1995, I was talking to the owner of Protomotive, Todd Knighton, about a 928 forced induction development I had begun when he mentioned this car. I purchased the car from Todd in 1996. Here it is as I received it.
- It ran "OK" when I received it. The original Engine Management was an Electromotive TECI. This was what Jarvis tech had originally installed/tuned in 1991. After some problems with the TECI, I decided to upgrade it to a new TECII in 1997. I got it tuned pretty well. As expected, it had great off-line torque.
- In 1999, and after learning a great deal from the DP car, I co-developed the first commercially available supercharger upgrade for the 928 under the FAST name. (Bulging hoods were not an option for a kit, so for the lowest cost, we designed a Vortech-based solution.)
- In 2000, I removed the supercharger and associated components and stored them. I pulled the 928 engine and dissassembled it for other projects.
- In 2001, I purchased a ZZ502 BB Chevy, converted it to EFI, and dropped it into the 928 and began designing/fabbing twin turbo headers for it. In 2001, after getting 80% through with the project, I fell out of love with the car and the project, and sold it to a chiropractor in Houston, Texas.
- In 2002, he sent me an email saying it was "running." Never heard back from him again.
- Later in 2002, I sold the stored supercharger and parts to Steve Cattaneo (eBay seller).
That's it.
