Sorry but I already have a turbo Subaru Sti with lots of power but I hate it. Nothing beats the response of a N/A engine. Im not looking to race anyone on the street, I just want to build something that is fun to drive. My car is already LOADS of fun to drive but all it lacks is a bit of extra grunt. For me a fun car has to be responsive and turbos are just not that. Sorry.

 

Once you turn the boost up on the sc to 12-14 psi it starts getting fast, not just quick. Stock boost they are not much faster then a bolt on S. Will pull some up top but nothing too crazy. Of course a 400whp turbo S will be faster than a sc S but it will also be faster than most supercars out there.

 

Just run E85,a smaller pulley that yields 18+psi up top, and more ignition timing. Problem solved.

Now I'm lost. If it wasn't for my 4.56 gears I wouldn't have much pleasure driving my S. It has no response because of the lack of torque. A S/C doesn't start building boost till around 5 grand and isn't at full boost till redline. This is because the S/Cs for our cars are centrifugal. A turbo responds quicker (depending on turbo size you could be at full boost as low as 5 grand when your S/C is just building boost) and YES harder then a S/C. Maybe if I had a big block under my hood I would agree with your comment of "Nothing beats the response of a N/A engine", but I don't. We have a low torque/horsepower engine just like most imports. This is why we use force induction to keep up with domestics. So not to start a feud but your last sentence is complete wrong. SORRY.

The pleasure of driving an S is not for the torque it for the high revs and power up top, even then, if you wanted torque your rpms should be much higher (5k on up range) where torque is present. Not all SC's for our car are centri's. Small turbos on our cars arent as bad as people make them to be, if done correctly. We dont have low horsepower in comparison to most other imports, and I keep up with most domestics just fine, it all about knowing what your driving and how to drive. Recently, other cars especially newer models are just now catching up to our 10+year old technology. Lastly, you can keep the S NA, it's just going to cost you for high power high torque numbers....search F27c

 

It's actually very correct. The response of the sc setups is at superior to turbo since there is no lag. If your up in the revs, where you would walkways be if driving hard, the second you punch the gas your making the full boost you can at that rpm. Turbo will need to spool up and then yes have more boost and pull. It still does not have the throttle response of e sc setup.

I make 4-5 psi by 6k in my car I believe. Nothing crazy but think I am making around 230whp by 6k rpms. Then it goes up quickly after that. Sc starts building boost around 2k in my car I think. By 4k it has a few psi of boost.

Up the boost and it will make much more boost all through out the rpm range.

 

i love my comptech even with only 6.8-7.3 psi and water meth and the [cheap piggyback emanage] i show 320 hp in 55 degree weather on a gtech pro. i've got about 8k on the blower no way i would go back to stock. turbos are great but they're expensive and you should know how to work on your car either way i think its important to learn any vehicle you modify. i like the supercharger because its predictable and reliable and as far as being beat in a drag race well if thats your goal turbo is the way to go but i like the twisties i have another car for the 1340. i love to see the s2000 run 8s but its a roadster and the supercharger enhances it better than anything else i've done to the car just my two cents

 

What's going on Mod? I know I picked your brain a bit about a S/C. A turbos power curve is superior to the S/C when you start building your boost and making 6psi at 6 grand I can be at full boost say 15psi with a gt3076. I don't want to step on anyones toes but that's why I always comment on a S/C vs T/C thread. If most went with a T/C first they would be quick to go back once they went with a S/C. There are plenty of members on here that have gone back once they try out a S/C. It's all in what you like. Some may not want a high WHP S or a car good for rolls and track. Each his own and everyone gets into the sport for different reasons.

 

Oh yeah you definitely will have a much broader powerband with the turbo and build more boost earlier on. However the "response" of the throttle is better with a sc. There is zero lag since its belt driven and doesn't need to spool or anything. So if your at 8k rpms with a sc the split second you touch the throttle you make the full boost at that rpm that the pulley makes. Turbo would not be as instant to give the boost but then would give more once spooled etc.

 

Ahh the age old question that begs comparisons to the which came first debate. Chicken or egg.

Get what you want. Both work well.
