twincharging is ment to use the instant torque of the SC for the low end and a larger turbo for the high end. Not the other way around because a roots blower is not a high end beast like a nicely sized turbo is. I would just stay turbo, and see what you can get outta the TD04. My TD04 is good for about 320hp, but thats pushing it. So thats why the procharger is coming in =P

The reason people think the turbo pulls so hard is becuase of the 5 seconds they wait for it to kick in.. Its like a roller coaster.. you sit at the top for a long time and it amplifies the effect in your mind.
One key note, a supercharger will have the same torque in every gear.. time after time. A turbo, the faster you rev, the less torque you will make. Especially in 1st and 2nd gear.. by the time your in 4th or 5th you will FINALLLY be getting close to the "RATED" torque and power of your engine..

Its funny.. America is the only car market that "likes" turbo lag. Every other country sees it as a problem.. all of europe, japan, etc..

I dont really understand the "turbo lag" argument...or maybe I just don't know how turbos work.
even with a huge turbo wouldn't it be better to hit full boost by ~4500 vs at redline (supercharger)?? And its not like you're not making boost below 4500 its just not full boost.

running a smaller a/r housing on the hot side will reduce lag, but also hinder topend performance and over all ability to make power.

second, stop typing caps.
third, learn the facts before spewing info that really doesn't make an sense, nor have an y basis behind it.

turbo's are a non-linear device... they rely on exhaust gas to spin the turbine... to spool the turbo, it requires a certain amount of exhaust gas to spin the turbo.. now the quicker you try to get the turbo up to speed, more of the energy is being placed into spinning the turbo 'inertia' up to speed. (i.e. turning it into kinetic energy)
The thing people dont realize is that the torque and power curves that OEM's show are "STEADY STATE".. even the OEM's admit that you wont hit those values in first gear..
I'm not saying you cant make awesome power with a turbo.. only that it will vary with how fast your engine accelerates...

^^First gear is so short anyways that my heart isn't terribly broken that I'm missing 3 or 4 psi of boost, even though I may not be at full boost, there's still plenty of pull in 1st gear.

my point exactly......you may not hit "full pull" in 1st unless you know how to launch without spinning...but it's not 1st that counts in most aspects...it's 2nd and 3rd on the strip that is going to bring bread to your table

so the Fedex gods were kind to me today and finally delivered my wastegate actuator and oil feed lines for the turbo project, looks like i'm running 8psi
of course now i have to fabricate the mounting bracket to hold it on the turbo and mod it to be able to fit on the wastegate itself (hole is a bit too small) but it looks good
now just waiting on the intercooler, bov, and a trip to home depot for the oil tree fittings, bolts,screws, crush washers, rubber hoses for the coolant lines, and my flanges for the downpipe and then to order the fabled aem f/ic and tune...then i'll be running the only 07 2.2 turbo that i know of

ive talked to a few honda guys who have turboed there cars and they say that when out of boost u can actually get better gas milage....a great part of turbos is u can daily drive them out of boost and still get the same gas milage....and on the weekends/when u want u can get into boost and blow cars away....
so its....constant boost.....or boost when u want it to happen....and once u go turbo ull never go back...and turbos u can always upgrade the turbo as u build the motor....ur just kinda stuck with the
M62
and yea the whine is cool but when u are in a race and u can hide the turbo....thats the best....they hear the pshhh and they know there screwed lol
