Downsides of tuning?

[monkeybear]

So I went out and purchased a copy of Siphon Magazine and in it is an article about a new supercharger for the Honda Fit. It says that there is a 35-49hp gain and a 27lb torque gain for the Fit with it installed. Naturally after reading this I went to the Jackson Racing website to see if he has one planned for the Versa, but alas it seems he dose not.

My question is this: Lets say he did. What kind of negative effects would a supercharger have on a cars engine? Would it be reasonable to expect the engine to have problems sooner, and would it be drastically sooner?

I know that the answers will not be certain, I just asking for supposition.

Thanks!

Any time you modify a car from it's stock position, you run the risk of things breaking. Obviously, wheels aren't going to cause things to seriously develop problems, but you get my drift.

The problem with supercharging stock engines is eventually they have a greater chance of failing due to the HUGE amount of extra pressure being pushed into the cylinder head.

You also have to worry about your fuel/air mixtures being thrown off. The stock computer is not calibrated for such drastic increases.

So while a super charger may sound fun, someone who ultimately chose the Versa for long term reliable transportation would likely want to avoid it.

I think it would be fun to tune my Versa a little bit, but not at the cost of ruining its longevity. I guess I will stick with the CAI/Strut Bar plan. The hypothetical superchager was a nice dream though, thanks for your response.

You can still install a super charger. Just as soon as they start producing parts for internal engine work it will make thing like that easy...

I had no idea where I was going with this...coffee is kicking in.

But ya internal first then external...if that makes sense.

Lain is right, if you don't beef up the internals (pistons, rings, bearings, crank, rods, valve springs) the engine runs the risk of blowing up a LOT sooner than you'd anticipate. Unless Nissan actually builds a turbo version of the MR18DE, there is little chance of these parts being available, outside of aftermarket. One of the biggest differences between turbo and n/a engines is the crankshaft; the turbo uses a much stronger crankshaft (forged, I think).

Don't forget the badges. If you add a supercharger and don't put new badges on the car you lose 10 hp.

Just trying to be funny.

Compression is a LOT lower...

That must be the difference I was thinking of. Thanks! (What about diesels?)

[jstugs]

what do you mean, "what about diesels?"

are you asking if you can put a turbo on a diesel?
