LS1 928 ------> LS3 upgrade 928

tv

response to M928 post #357




The exhaust sounds nice when revved, I have never liked the sound of a supercharger whine.

My point is why don't they make these cars special instead of jacking up HP with all these superchargers -- ZR1, LS1, GT500, and now this. 707 bhp and it only improves upon the 2014 Corvette with 460 bhp by 3/10's in 0-60 time. All that power does little good.

Why can't they equal what they once did or improve upon it. It has been 50 years since Ford built and sold over the parts counter the 427 shown below, N/A could produce over 700bhp and rev past 7000rpm's. With 50 years of knowledge they should be able to build it as good or better and for a decent price. Today's muscle cars with engines like this would be as desirable as europe's best. Even the viper doesn't come close to this thing. Why?

I have never heard an engine sound as powerful as this thing, listen @ :35

I already have my 'next car', alongside my '94 928 in the garage. It belonged to 'Bigs' in Utah a year ago, and is in appreciative hands hear in southeast PA. Picture is from 'Bigs' driveway.

A 2003 SL55 AMG in firemist red. I've added ~50 hp and 50 ft lbs to an already ultra high performance car (now ~545 and 575 respectively) and raised the speed limiter to 300 kph (186 mph). Also changed the wheels to a set of OE 2 piece 19" wheels from a 2006 V-12 SL AMG.

Learning the maintenance procedures on this semi-exotic is almost as much fun as learning them on a 928! BUT - there is nothing to compare to the 928 Rennlist Forum in the MB/AMG community.

Just picked up a 2001 Honda S2000 silverstone w/ red interior with only 35000 miles on it. I'm through with project cars... need to refocus car time on the family business due to my father's ailing health. Can't be wrenchin' like the old days.

Fantastic ride you got from Bigs at a great price I thought.

Any nervousness over the hydraulic suspension system?

The Forgotten On

If I could I would buy either a 2009 Audi RS6 avant or a Mercedes Benz SL65 AMG Black edition. It's just too hard to decide which is more insane.

Randy,

One of the many 'learnings' regarding maintenance over the past year obviously was the Active Body Control (ABC) hydraulic suspension system - a marvelous system - which MB said needed no maintenance. WRONG. The fluid is hygroscopic, just as brake fluid is. Found a German company's procedure for maintaining the system and their history of cars with 200K plus miles on them with no problems. I adopted their procedure - completely flushed the system and installed a magnetic filter. I'll repeat the flush every 3 years, and expect minimum/no problems. the key for the ABC system seems to be the maintenance that MB/AMG ignored. I also drained/flushed all fluids in the car (10 years/45K miles) including the supercharger oil. It runs/rides/handles and drives phenomenally (and the hardtop 'folding/lowering system' is a hoot).

Gary that is a stunning piece of machinery, I know Bigs really loved it.

tv,
Todays cars with the same horsepower or more than years ago,get at least 2 to 3 times the gas mileage with superchargers or turbos
Todays cars cruise at 20 to 25mpg with way higher top speeds and still better 0-60 and 1/4mile times.
Example is GT500 24mpg highway and have way taller gears that have top end toward 200mph.991TT same thing great highway mileage.
You have to look at power to weight.A Corvette is closer to 800lbs or more lighter than a Challenger.
Start looking at the total package power to weight that will explain 0-60 times and 1/4 mile times also.
The heavier the car they increase horspower to match to get 0-60 inline with lighter weight cars.
I can't say Euro cars are more desirable look at sales numbers and compare that will answer which are more desirable.
For the 2015 Z06 they claim the new auto at full throttle is .8 millisecond and faster than the Euro dual clutch trans!
The way they stated it You won't find a more responsive high-performance automatic transmission in any other sports car on the road.
I don't look at Corvettes in the same class,Challengers are more compared to Mustangs and Camaros which the weight of these cars are much heavier than Corvettes.
Do you realize how much it takes to go just .1 faster 0-60 when down in the 3 second area?
Take a look and try some numbers.
http://measurespeed.com/zero-to-sixt...calculator.php
It may not be 100% accurate as other factors can change times.
EXAMPLE
700HP 4200LBS 0-60 mph 3.44 seconds
750HP 4200LBS 0-60 mph 3.27 seconds
Your only going to pickup alittle ET maybe .15 with a heavy car in the 0-60 even with 50hp changes on the same weight car,
its not like running a 1/4mile where the ET is seen alot more of a gain.
The transmissions with more gears,quicker shifts and launch control helps more in the 0-60 area.
Thats why you see test of a 997TT S in the 2.6 to 2.7 area but at what cost 180k to 200k !
Muscle cars are priced with the bigger motors more in the $50k to 70k area.
All wheel drive,launch control,and quicker shifts makes the 0-60 times alot better.
Change a Muscle car to all wheel drive and you'll end up with a heavier yet over priced car at $150k+
like Euro cars and how many are going to buy it compared to where sales are now?
Once the factory makes engines at 700hp tuners will take them to 850hp+ and its not wasted once you
bolt a set of slicks on or really good drag radials all that power changes more in ET.
Its not wasted horsepower you just need the right tires!There are plenty of cars out there like that and most know it.
Stop the video at around 60mph and see where 0-60 times are more like low 2's!!!!
What are you going to change on a muscle car to make it better and what cost to make it all wheel drive
then who is going to spend that kind of money to buy it?
They are what they are to bring back part of the heritage they had
big motors,more power and slap on a set of good tires or slicks instead of spending $150k+

You answered your own question right there, and the old 928 sales question. Almost every buyer of a 2014 Challenger would take an F12 if offered for the price of the Challenger. Price directly affects sales numbers, basic economics.



I personally don't care if today's performance cars get good gas mileage, because they are such a small part of the car fleet. And as time goes on with electric cars taking over, it won't matter at all if 100,000 cars get made with gas guzzling engines.



One of the enjoyable things about the local car and Coffee meet is all the old 60's cars that show up with huge engines that rumble the pavement from vibration. These new supercharged engines don't come close in the impressiveness category. I am not much into drag racing on 2 or 4 wheels.

I know I answered it was just stateing a point and also with a question as do you know since you asked why don't they build them different
but now you answered that which is what I meant,thats why they don't change them cost and sales.


Hopefully by then they will have a good recycle program for batteries if everything becomes electric.


That probably will also be the enjoyable things in the future when at a car meet having a big motor supercharged car while there is electric cars quiet as a mouse.
I've always been into drag cars or bikes that were something you can drive on the street but with the 5 to 8 MPG the car with todays gas prices didn't drive it alot
thats why I like the newer cars with turbos or superchargers you have both power and gas mileage you can take them out and drive them.
Maybe some 928 owner who have a 928 or other cars with a turbo or supercharger will post why they did it.
Some people are impressed by the superchargers some aren't its a matter of what someone likes.
I like both but having more driveability at 1/2 or maybe a 1/3 the cost on gas with the same power I like better.

Hold On

Hey Joe ! Your in luck. There are some Metropolitans coming up at the Auctions America Burbank sale, last weekend of this month. Should I call Dee and remind her for you ?? lol

When I purchased my 928S4, brand new in Germany in 1987, I pretty much fulfilled the dream of a lifetime. That adventure is beyond me now but I still enjoy driving the car and would never give it up for a Panamera or any other of the Porsche newer cars. A brand new Ferrari or MB might tempt me but I would have to think about it for a long time. If Porsche came out with a new, truly a 928 upgrade, I would absolutely jump (if I had the money - a very severe limitation).

Hah, she's changed her mind. I can get a Mangusta, or DB 9. She really loves the Aston.

I'm looking for a Mangusta. They're hard to come by.
