A friend of mine has a 2001 silver S and a Vortech supercharger with all the necessary equipment (ECU).After 25.000 miles the engine was off.
Can anyone tell us if this has happened before? How can we be sure that it wont happen again? Any special mods required?
Thanks guys.

Let somebody reputable and knows what they're doing build your motor and tune your car.

Engine let go?Can you be more specific?You need to be more descriptive on exactly what happened to the engine(blown headgasket,fried pistons) ect ect.Then maybe someone can help.You cant just assume that the supercharger blew the engine!!More details please!!

AusS2000

Poeple have blown stock engines with less miles. Others have installed SCs with small pulleys and done many flawless miles (me for example).

The question is how did the engine blow (valve damage, scored piston, rod through the block etc) and how did you buddy drive it?

One piston came out in pieces . I guess that high revving stock engines and SC or turbo don't match very well together.

I blew cylinder 4 after only 2000 miles with the Vortech

Maybe 100% of your F20Cs have died whilst supercharged but you'd have to be pretty short sighted not to see that many others have been supercharged for many miles. In fact I'd say that whereas the percentage of SC'd F20C that have failed is probably higher than the number of NA F20Cs it's not drastically higher. And soem of the increase can be attributed to the type of owner who supercharges an engine. The sort that push their car hard. They will have a higher failure level FI or not.

So whereas there is no arguing that your engine was supercharged and your engine died (as did kstokell's) that is still not conclusive that 'high revving stock engines and SC or turbo don't match very well together'.

One piston came out in pieces?Do you mean that the ring lands broke?If the ring lands broke then there was heavy detonation going on in there.Was there a hole in the piston?How did the other pistons/cylinders look?Don't assume that the f20/22c are bad for forced induction just because of there compression ratio and high revving nature,thats just ignorance!!

In my opinion any increase in power will have a knock-on effect in engine life but as AusS2000 says if you look after the car and drive it with a little respect (do not use full power for extended periods) the reliability should be OK.

My engine blew after 7 hrs of pretty hard driving whilst returning from Italy to the Netherlands. At the time I was doing a sustained (2 or 3 minutes) 270 kph on the German autobahn (just below the rev limiter in 6th. gear). This proved a little too much for the engine, up until this point I had had no problems, so my feeling is if you use the extra power for short bursts ,(during accelaration), you should not reduce the engine life by much.

Now that is certainly working the car VERY hard!!!You must have a big set!!!Was the kit stock?Also did you verify with a wideband that you're af ratio was safe around 12.5 under full boost at wot???I think the engine would need to be run extremely rich say an af of at least 11.5 to be able to survive those torturous conditions.I have no intentions of running the car that hard!!
