blown996 is infamous around these parts
almost 20,000 supercharged miles on my 2000, 47k total. did 20 track days last summer most in 90+ temps , never even overheated. drove home from watkins glen to boston 3 times after running hard on the track, never skipped a beat.

I know of NO M96 engine that have failed running with a bolt on charger. As a matter of fact, none of the manufacturers of the systems available have heard of any either.

I won't even bother to ask you foir supporting data, since it is all in your imagination.

FYI, there are probably no M96 engines running a higher effective compression ratio than my 99. 40,000+ miles on the charger and almost 70,000 on the engine. Still trying to break something, but no luck so far.
Sorry man. I didn't mean to wreck your Saturday. When it comes to FI motors I am admittedly old school (Build it from the ground up or buy a TT). It is ok to disagree... I don't take it personally. That is the purpose of an open forum. A free exchange of ideas. Take em or leave em.

While it is great fun to document a new SC install including dyno charts for all to see, most guys won't do a big internet write up on their dead SCed motor for obvious reasons... no joy. Still there are plenty of examples of "cooked" SCed M96 motors just a few google clicks away if you really want to look for em.

If your 996SC is running great power to you. I say just keep driving and keep smiling.
Peace

Then it will be easy for you to provide us with a Google link to these documented blown m96 engines due to a bolt on supercharger system? I won't hold my breath waiting. Trying to justify one false claim by making another, is not a good way to build your credibility on this forum.

BTW. There is no such thing as an M96 motor in a Porsche.

1999,
Geez, angry much?

I thought you didn’t want to see any examples of FI gone wrong. Since you asked, here you go. A few easy ones to get you started so you can give up that chip on your shoulder.
The first three are all very fresh and all forum members, different motors, all failed last year and within one year of adding FI. There have been many others over the years. Most of the local cars in SoCal just flat bedded their car home and chose not to air their tales of woe on the internet. They are still around though so we could probably get you a written deposition if that would make you more comfortable.

6speed JP-S-St.Louis- 3.2L, IA SC, lost compression, selling SC, installing3.6
6speed Jaay- IA SC “flashing CEL, white smoke, low compression, motor swap.
6speed Boostiality - Single turbo bolt on, blown shortly after install. motor swap.
Renntech http://trentcarter.com/Boxster.asp (dead link) SC blown motor

So I guess I will stick to my story. FI on these relatively fragile motors seems a little less than ideal to me. It brings them to the ragged edge of performance and reliability. One bad tank of gas or missed shift away from a white cloud and flashing CEL. I view a race car with sponsorship, R&D team, and prof. drivers very differently from the average Porsche owner. The race team expects to toss a few motors each season. The street car owner needs to get to work, take honey out on the town, and might actually want to pass a smog inspection on the first try. To them a suddenly dead motor is a tragedy.

There is an almost **** obsession with "horsepower at any cost" just under the surface on this forum that is a little disturbing. Those with dissenting views are quickly dispatched or driven away. Maybe we should take a poll and all those not in favor of FI should be immediately banned. I know... next Crystal Cove meet we can go around and smash the windshields of all the stock NA cars. “ Kristallnacht II”. Then we can round them up, confiscate their cars and ship them off to Manzanar in boxcars.

Enthusiasm is good, fascism, not so much. It’s just a car forum. It’s healthy to disagree once in a while. We don’t have to burn each other down over it. Good thing I got a couple of extra layers of Nomex in my fire suit.

As I thought. No links to anything, just unsubstantiated claims. If we were to assume that the 4 problems you mentioned are true, what makes you think they are related to a supercharger? Cause and effect?

Some stock M96 engines are know to have slipped sleeves and other cylinder problems requiring the engine to be replaced. Each of those engines were probably running Mobil 1, so maybe that was the cause? A bad engine is a bad engine and sometime they will blow regardless of how well you care for them.

But, beleive what you want. I personally prefer high static compression engines boosted rather than low compression boosted engines and the M96 engines have no problem handling the boost.

I sure am glad I don't go through life as paranoid as you thinking that doom is inevitable.

With 110,000 miles on your engine your going to want to rebuild it before turbo or supercharging it. I rebuilt mine at 106,000 and installed the Vivid Racing Turbo Kit.
