Very simple stuff.

There is a lot of development going on that is not talked about.... When it gets commercialized.....you will hear about it through the retail channel. Anyone interested in knowing more can use PM.
Thanks for the explanation, Gretch.
Censorship is never positive, in my opinion. That includes, self-censorship ("They can't make me shut-up if I don't say anything").
I miss the input and exchange. Diversity maintains strength.
Stay vocal, Gretch.

And I found some CERAMIC bearinsg in the sizes needed for the V-1s. This is supposed to make them more efficient, heat-production-wise.
My point is that BECAUSE I bought from ebay, I took it apart.

I always have to take something apart. It makes me feel better. 928s, bmws, engines, interiors, computers, superchargers....

We tried a "shoot-out" once to put MAX HP to rest once before, Remember?
The 2004 928 OCIC convention in Wichita KS? There was supposed to be a stroker car, and a FAST car, and John Kuhn's Turbo, and me witrh a CS car.
But I am the only one that showed up at the dyno. Where were you guys?
Seriously - this has been a good, tame post. It seems as though we have collectively matured a bit.
Yes, 525HP and up with the CS kit is well documented and we have repeated it many times.
No, max HP is not the only thing you should consider when selecting a kit.
Ask yourself:
Q1: Where do you like your power - where do you like to drive - 2 to 4000 RPM (like an automatic) mostly or 3 to 5000 (Like a 5 speed)?
Q2: how comfortable are you with a wrench in your hand? Do you prefer a more involved installation, or an easier one?
Q3: Do you like Supercharger "whine" or do you prefer the "Stealth" approach?
Q4: Do you have to do regular emissions inspections in your location, or no?
I have more (lots more) but I am sure that will get you started.
Jon, all the kits and proposed kits are a box of compromises. Each one does X better than Y. You need to make your own list of objectives and select accordingly.
Give me a call toll-free at 877-FOR-928M and I can explain more.
The wonderful thing here, is that for a discontinued, limited-production automobile, is that you have choices at all! Amazing.

Hey Carl...that weekend I was nursing a very sloppy trans...I had to make sure I could get home. The tranny could not hold the torque at all. Remember, Goldmember was driven from Cincinnati to Wichita...it was never a "trailer queen". The Goldmember put down 270 WHP and 355 ft-lbs torque (3,300 RPM) on 9 psig. When it was dynoed it was a full 100F in the dynojet room. Bad move on my part...that temp cost me at least 25-35 HP guaranteed...possibly more. Those were K-24 units...very small turbos running through a slushbox with stock 80 cams on a 100F day with minimal intercooler flow.
The GM HP curve was basically flat from 3,500 to 5,800 RPM. When I dynoed the Callaway it was like 65 degrees and the car made a full 100 HP more than the Goldmember. Larger turbos and just a few psig more boost, plus cooler temps.
I hope to have K-26/Euro cams installed soon.

I waited 9 pages to chime in...
I have the supermodel kit, I like it, I like what 928 Specialists has done to improve it.
Having owned but never installed a vortech based kit I can say just from appearances the
Carl/ Murph system looks great and should run great.
It seems like a win win situation... seriously.
