That would be a good comparison. I'm not at all dissing the twin screw but just clearing up some of the facts.


BTW, I have been getting messages that I have a PM but when I click on it to open my computer blocks them. If anyone is trying to send me a message please try Murf928@new.rr.com

Tim,
If you wanted to clear theings up you would have used Don T's chart.

This chart you have added is just going to confuse people.

I have to call BS, and say that I am very disapppointed.

I guess I had to disagree with the above post so I put up some real world results to make some comparison with. I would post DonT's vs the twin screw but I don't know how to put them together. Someone sent me the one I posted.

GoRideSno

Speaking of real world. Do you have anything like this to show Tim?

Those are some great numbers. If I ever get to a drag strip I'll be sure to post my results and I will be very pleased if they are as good as your results.

We all know that drag racing has a lot to do with tires, and driver.

If we really want to clear up all these issues about superchargers, strokers, turbos, etc, we will eventually need to see numbers from a totally stock s4, or s2, with the different kits, running the same amount of boost. Any other discussions are just a waste of time.

BC valid point about drivers ; note that Andy's reaction time of 1.014 seconds means he left about 1/2 second on the table due to driver error ! an experienced drag racer could probably get that car on that day into the high 11 sec range . And that is very , very quick .

I want to see the MURPH kit on a stock s2, Andy's kit on his stock s2, and John's turbo kit on a stock s2... Set to the same boost levels, and dyno the cars.

Eliminate driver error, or the fact Andy has stickier tires than John, etc...

BC,
Nobody is asking for drag racing results or talking about drag racing at all. Does Porsche advocate drag racing because they put 0-60 and 1/4mile times in the owners manual?

I just want to see a 1/4 mile and or 0-60 time, just like those listed by Porsche in the 928 owners manuals. Making a car go faster IS the goal of making more HP. There are some MAJOR differences in the way the systems actually perform in the real world. I would just like to compare them.

I think it will just take time...

Eventually there will be a decent amount of people with your kits on different 928s, and eventually there will be a decent amount of people with MURPH kits, and then we will see more numbers...

And even if they do post 0-60 times, or 1/4 mile, I still say that driver skill, and tires, plays a big part. If someone with a Murph kit, has a widebody, with huge sticky rubber, and a great driver, they will post higher times than you, even if they dyno lower...

I still think the dyno is the key.

How you get the power to the ground, is different for every car, every driver, and every track... Power numbers are fairly consistent...

The key to success of each of these kits will largely be dependant on how the vendor deals with their first "bad" customer. I'm not saying that either kit is bad, but that eventually as more and more of the kits are out there.., the sellers will deal with a situation that will test their resolve (ie. blown up engine, improper install, bad base engine, excessive mods to kit etc..etc)

That said, I hope this doesn't end up in a west vs. east war....after all....the desired end result is the same for all parties involved, and that is a faster 928.

Cheers to all who take on these kinds of projects...who would have imagined a few years back..that there would be several options beyond the stroker motor..to get around 400 plus HP....and all for basically reasonable prices..

Later,

It will eventually come down to a cost issue.

They will all get refined, so they are safe, sane, and well-designed.

The differences are not so huge preformance-wise.
They will both put a huge grin on your face,
and both kits will make your 928 faster than most
cars on the street...

So for most people, it will come down to bang for the buck, not a 50 horsepower difference at high rpm...

Shane .... you are definitely an enthusiast, and I can't wait to help you drag Helmut and Heidi. Thanks for the offer

Andy .... them's some purdy numbers Bubba!!

Jim bailey - 928 International

Yes Heinrich with those numbers one could do the " on ramp olympics " and win nearly all of the time not that I am suggesting that people should .
