Supercharger or Turbo ?

[ichitaka05]

Hm... from the spec, I prefer NA... but SC would be nice too. Love the sound of BOV of TC too... BUT this one I gonna go with NA

[Jordo!]

Oh, to clarify, I was talking about a roots-type blower. Centrifugal blowers make peak boost even later than turbos (although they have a higher potnetial top end).

If I had to pick one, I'd pick a slightly oversized roots over either a centrifugal S/C or turbo (although a twin turbo set-up would also be nice).

Of course, whoever said twin charging (I assume meaning roots S/C + big turbine)definitely has the right idea -- the best of both worlds!

if i had the money I'd probably twincharge it

Would be sweet

Votes are pretty even right now

Supercharger because I love the instant response on NA, but long for more torque. Laggies are a no no for me. If I dragged or raced a lot then turbos for more power but I don't so SC= torque low and preserves the high revving nature up high

Have any of you guys crying about lag driven a car with a modern turbo?

uhh, are you kidding? you want a 2.0L with TWO TURBOS??? one properly sized turbo will outperform two turbos in every respect.

Although, that said, I won't turn away from a turbo version if one is made available from the factory.

you need to recalibrate your opinion on turbos. it's incorrect. you've probably been spending too much time looking at supra 1000whp dyno graphs, and not reasonable cars with turbos. my MR2 makes 240whp and 250wtq, with a VERY broad, flat torque curve. more responsive than almost any other car i've driven.

agreed. a properly set up turbo car is just as responsive as any other setup. and i've said this before, but "any driver who complains about lag is either in the wrong gear or the wrong car."

lol so true, modern single turbo perform awesomely!
Just a note, iirc JDM Legacy did EJ20DETT (240hp-ish), so it's not impossible, but I think it's just a waste of space.

True. And with the better turbos we have now it's really not necessary unless I want a huge turbo.

[Jordo!]

Ehh even a small, fast spooling turbo will tend to make boost at least a few 100 RPM later than a comparably sized belt driven roots blower. Perception of lag is relative.

The small turbo will also tend to run out of breath, and have a humpier torque curve. This is why twin turbos and twincharger set ups are still quite popular.

Turbos are a lot better than they used to be, but you will still see flatter torque curves with a roots blower, pretty much without exception. Turbos definitely rule the roost when it comes to top end tho'.

[Matador]

I'll ask again, Ever driven a modern Turbo car?

Roots blowers obviously get on boost sooner, but really, if you look at the trade offs it really does not make sense in a non V engine config.

Speaking of which, how do you really plan to put a roots blower on a flat 4?

[ddoouugg]

Turbos may not lag very much any more but they still lag a little. It's just their nature. There just isnt that instantaneous throttle response of an NA setup or blower. No argument over which is more efficient or overall a better setup for performance numbers though.

[NESW20]

want to know a secret fix for "lag"? DOWNSHIFT.

throttle response has nothing to do with turbo lag. there is a difference between throttle response and boost response. a good driver will be in the proper gear for conditions, and thus, this whole lag argument is moot.
