SuperCharged 5S-FE, Does anyone have this? Options

[Bigmeanbulldog55]

Any one have a supercharged 5S-FE? I'm just wondering, because a buddy of mine and I were talking about doing this to my car. All I have to do is get an aftercooler and then we're set. I'd like to know if any one has this set up so that they might be able to tell me about any problems I might incounter. Thanks ya'll.

Fact is, I would have to run higher boost on a turbo to get the same low-end effects as a supercharger. Also, with power only at higher rpms, I would have to run at a constant higher rpm to get the power that I want. I just think that a supercharger would be easier on the engine. If I were shooting for 300hp, I would go turbo without question. Or if I were going for a race application, I would go turbo. I just think that a supercharger is better for daily driving. I always thought that was a fairly well known fact. A turbo being better or a supercharging being better depends on the intended use. I’m also using a smaller supercharger and more than likely going to try to run around 7-9 pounds of boost. Maybe the fact that most of the time I’ve seen turbo chargers is in a high boost situation, which tends to make them less reliable, so my views are somewhat biased. A low boost turbo would likely be as reliable as a supercharger, but you would still have to push to higher rpms to see the same power.

Nope, no matter how much boost you push through a turbo, unless it's VERY tiny you'll never gonna get the great low end power that superchargers provided.

Most people who turbo their cars on this site- or have 3sgtes, run at 8 psi which is exactly the same 8 psi you'll be putting through your supercharger (also, for a supercharger, psi depends on the blower, etc). So neither is more inherently reliable over the other when they're running at the same level of boost.

I'll say this again, I'm not trying to make you choose a turbo over a super. I think it'd be great (awesome) if you supercharged your 5sfe. I'm trying to help you by pointing out possible kinks in the plan, and flaws with your thinking (that at 8 psi a super will be more reliable and trouble free than a turbo- they'll both trouble!)

One more thing, on our 2.2l turbo'd engines we reach full boost around 3.5RPMS or below, we don't have to hit 5500 to actually get boost
