Here's a thought.... It's time to just leave these cars alone and preserve them. Even with major high dollar mods they are not competitive, reliable, serviceable or safer than modern cars. Modern examples can often be purchased that are 3 to 5 years old for less than the cost of mods alone.

Case in point... Cars like the CTS-V. A Stylish coupe that make 600 HP with basic mods and has real successful racing history. Used around 30k and a TR-6060 available if you want one. Enjoy it for a few yeas and sell it on for about what you paid. 75% of the dollars you put in a 928 turbo, stroker, super charger will never be recovered and the car will own you instead.

Life is short, time is money, plan accordingly.

The 928 is what I'm on this forum to discuss. And I started this thread to discuss enhancements to the 928's powerplant. I enjoy little projects like this. It's part of how I enjoy life. It's not everyone's cup of tea. Just as a CTS-V is not my cup of tea.

Carl,

I would opine that it is a very complete definition. Not sure where the term Hewland fits in other than they made what was purported to be the first racing transaxle in the late 50's only to be informed that certain Herr Ferdinand Porsche did something similar in 1933.

Your comments and those of Jeff [Speedtoys] although contradicting each other were both very interesting albeit somewhat off topic- the subject matter might make an interesting thread in its own right.

Carl Fausett

I agree.

Thanks a lot Bulvot. There are more pics in my thread titled "928 Spyder Maiden Voyage" if you're interested which is kind of the thread where I post my updates now. It was the one I started after the car was initially put together and my son and I drove it from SC to WI for Carl to fit the Z06 6-speed into it. Great memories on that father / son road trip





Here's a thought - I don't buy any of my cars to ever resell them and am not a fan of the current generation of cars with electronic gizmos, all touchscreens, and driver aids. I buy the cars I have because I like them, and like them even more once I've customized them to my tastes. I don't really care what it's worth to anyone else, as it's worth every dollar I have in it to me, and that's really all that matters. Besides, once the roof has been cut off a 928, any originality is pretty much out the window and I purchased it that way. My son loves it too, so it's one he'll inherit at some point, and it will be another generation later before he cares what it's worth on the used car market. The only thing I care about is that in the event it's ever in an accident that I don't take a bath on it, and all my cars are insured for Agreed Value with Grundy for at least what I have invested in them, including the modifications, so when a texting teen T-bones me, I'll take the check and find my next unique ride to further customize.

I have no interest in a Cadillac CTS-V, or frankly any car newer than my 2009 Cayenne Turbo S - (yes, I destroyed that one with mods I like too). Don't really care if a CTS or new Camaro, or newer Mustang can run circles around my 928 or not. I can look 100 yards in any direction and see 5 of those - how many 928 convertibles do you see in 100 miles...

...that's what I thought...and that's what's cool, at least to me, which is really the only person I'm trying to please.

Those road trips with a son or daughter are wonderful. I have had more than one with each of my boys, and one with my daughter. Memories forever! Great bonding experience. In one, my oldest son and I flew to Coral Gables FL to drive our eBay purchase, a 1978 928, home. I still have it. Its the race car. So many stories of what we had to do to get that car to make it home. It did. In another, my son and I drove his BMW to Daytona, had a track weekend and drove it home - without incident. Whew! All good stuff.

Pete, I agree with you. It's the journey in life that is enjoyable. Which is why I prefer to modify or build just about everything that I own. Car or otherwise. It's not everyone's idea of fun, but it's mine.

I thought that the Murf systems were no longer available. Am I mistaken?

Long story short, at one time, 928 Motorsports became the marketing / sales arm for Murf928.
Tim Murphy, myself, Mike Schmidt (aka Z), and Twin Turbo Todd focused on the improving the kit, support etc... and took care of shipping and inventory.
Todd was responsible for some of the manufacturing too. It was just easier to have him weld up a lot of the parts versus trying to have them manufactured.

The original agreement between Tim and Carl was 928 Motorsports would supply their own kit for the 16 valve cars, and the 32 valve cars would be the Murf928 kit.
That worked out great for years.
Somewhere along the line Carl decided to break that agreement and started to produce and sell his own 32 valve kit and dropped the Murf928 product from his website.
Tim never did anything to break this agreement so needless to say this came as quite a surprise. At the time Tim was going through some personal issues and didn't have the time to pick the torch back up so things appeared to fall by the wayside. A few kits were still sold directly from Tim, but family comes first and he simply ran out of time to do everything and I could only be of so much help.

Fast forward to today, I'm working on making a Murf928 kit for my 87, and my goal was is to make enough parts for 5.
I already have the machine shop lined up and Todd has agreed to do whatever is necessary to help out.
I'm in constant contact with Tim and have been part of the Murf928 product since day one. He lives maybe 15 miles from me.

The goal was to have all of this completed last spring, but a deer hitting my 80 and setbacks with other projects got in the way.

The Murf928 Stage III is a tried and proven turn key way to have 500rwhp with a 32V 928. The kit could make more, in fact Tim's personal car made over 550rwhp but Tim was never interested in selling a kit that produced more power. That was his own personal decision based on various cars we built and drove.
Seeing what Todd all had to do with his car to put the power to the ground.........I tend to agree with him.

Absolutely, and the person who does the tuning for the Murf928 setup is Luke Stubbs at Beyond Redline, the same person who helps Twin Turbo Todd tune his car. He's a world class tuner who fly's all around the country tuning engines that make even Todd's 1,000+hp 928 looks mundane. We are really fortunate to have him local and I'm not sure I would be bothering to supercharge any of my cars without him.

Bigfoot928

so do the Murph kits come with chips to negate having to tune each car?

hacker-pschorr

The earliest kits used an FMU. Once the Shark Tuner came out the FMU was ditched and kits came with 42lb injectors and chips tuned for the kit, even the Stage 1's.

Lizard928

YES!

All the Murf kits come with replacement chips which make the system plug and play with the SC system. No additional tuning is required.

Carl Fausett

This has been the story from the MURF camp for a long time and it is not true. There are a couple facts in there, and a lot of fiction. I have tried very hard not to throw Tim under the bus all these years, (after all, I sold 16 MURF kits for him and 5 Stage II upgrades, installed several of his kits, and rewrote his installation manual for him as a favor before we parted company). I still do not want to throw him or our business relationship under the bus, but I see that the MURF camp, now represented by Erik, has no such reluctance from doing that to me. Fine. Let that be on them.

So - I'd like to talk about only the supercharger kits, and not the people.

I will respond to the concept of 1) mailing a chip with the supercharger kit and calling that a "tune", and 2) the limitations of Sharktuning, especially where boosted applications are concerned. Right now, I have paying customers in the shop. I have to put them first at the moment, I hope to respond to this post tomorrow.

I would like Erik to tell us what has been done to solve the overheating problem caused by the MURF cold air intake blocking the radiator. The earlier solutions for this problem were just throwing more fans at the problem, which resulted in alternator failures, upgrades and melted wiring harnesses (ask me how I know!) and more than a few blown head gaskets caused by the overheating. I hope they have re-engineered and have that problem solved.

Just out of curiosity, are the S3 kits not part of this revival? Or can the kit be ordered in either S3 or S4+ configuration?
