That is what I am seeing as well. The fuel cell is dated 1992, and I believe the fire system is close. The seats and harnesses I have were the same ones in the Excellence article, although the seats have been recovered.

My guess is that sometime after the Excellence article, Devore decided to go full track car. Here is a pic of when he finished it, taken in AZ.

Last time I checked, I was paying for the motor. And the guy I chose was Carl. No offense, but I have never heard of you and we live in the same county. Maybe you'll get the next one, but for right now, Carl's the man, and let's leave it at that.

I don't want this thread to devolve into a dick measuring engine builder contest.

If I'm not mistaken, Bud Hart is living in Texas now. His son Jason, who is quite the racer, is in Flower Mound TX. Bud has been to a few DFW 928 breakfasts - always a treat to hear him speak about his history with the 928. Sean or Roger may have his contact info.

Some reference to the Devore car here:

No one, actually. As far as I knew, Carl was the only one doing it.

Looking forward to seeing this....

Good luck with your project!

While we are on the topic, what NA horsepower have your builds achieved?

Here's a good start, Cliff notes version is ~610 crank hp, N/A:

^That's pretty good. I did not know that when I said "highest horsepower NA build". I don't think my motor will make 610 crank nor have we tried to get that much.

This honestly was not my prime goal here, and I don't want to distract the thread with that kind of rhetoric.

Keep in mind that in order for me to get 500whp in my Camaro, all I needed was to add a big cam, port and polish, a cold air intake, and a tune. That's it. It cost me about 3K to get that on my 6.2 LS3. That car currently makes almost 1000 hp.

I currently own 6 Porsches, and honestly, the 928 is really in the middle as far as power of my cars go. I love 928s, but I am not a Porsche fanboy by any stretch. This will be a nice strong car with ridiculous levels of mechanical grip due to the huge tires, unparalleled on any 928 I know of.

Let's move on!

Agreed! Looking forward to seeing your progress with the car, I'm happy to see it coming back to life. Motivation to get mine rolling again too.

I am drooling all over my keyboard looking at that pic! Beautiful. Hopefully it will regain it's former glory, thanks to you. Best of luck with it.

Are you building a 2 or 4 valve engine? Kind of hoping it stays 2 valve and period correct. Bob supposedly had some outrageous numbers for his engine builds.

Forget horsepower....look at torque.

Where does that engine start to make over 400 ft lbs? Now look at the gear ratios in a 928. What rpm range does a 928 engine operate in?

928 V8 power is way different from 911 power....

BTW....I love that you are "rescuing" this car.

Kudos to you!
I'm not a 911 guy at all, even though I own two 911s right now and have built many 911 engines. I like the cars but I do not consider them my favorites....I also mentioned that this is my FOURTH 928. I was one of the first people to run around with a supercharged 928 in 2002, made 400whp, a lot for those days.

Also I have half a 928 engine in my 951 so I am pretty familiar with the water pumpers.

4 valve stroker. Keep in mind that the supposed monster motor in this car was GONE, not a trace of it. No exhaust, no headers, no plumbing.....GONE. I am not sure when this motor was removed or what became of it.

For my goals it was easier to create a competitive power level with the 4 valve engine and most of the aftermarket products out there are for 4 valvers. The 4 valve 928 engine has some serious power limitations, especially when you're talking about how big of cams you can put in it because of the head design.

I am not surprised Bob was making big power with the 8 valve engine at all. As I said my Camaro LS3 (different architecture obviously) is one step removed from a tractor engine and makes huge power almost effortlessly because its big and dumb and has few moving parts, in some ways kind of like 8 valve 928 motors.

Whoops hit post too quick....

...when I say competitive, I mean against a similarly classed GT1 911 based car. The 3.8s and even 4.0 engines in those cars can easily make 400+ horsepower, and they are usually much lighter than even a stripped down 928. An RSR is a hard car to beat with a 928, but I want to try, because I believe in the 928 and always have.

Great thread. Keep up the good work! What is your racing background and where do you think you will ultimately end up racing the car? Lots of history in this car. Good luck with the restoration.
