DIY ITB's: streetable?
i'm not considering this myself, but i've been wondering for a while. DIY ITB's have lots of technical info here, but little to no data on the improvement it made on the car. when i say "car" here, understand, the topic is for "street cars." anything that does not serve most of its time on the street does not apply here. i'm interested in how different combinations of engines, with their varying levels of modification, compare to each other with similar or dissimilar tuning and other mods.
of course, engines tuned with high-end standalone management will perform better and will be simpler to drive, as they can warm themselves up as needed and idle more easily. however, i'm more interested in those using hondata, uberdata, or an S-AFC or similar. the cheaper tuning.
include the engine and mods, then the tuning device(s) and method, ie wideband on the street or dyno or "i'm retarded i just tried to run it." then include fuel economy, peak power, power delivery (low end and midrange and top end), driveability (warm up routine is longer, won't idle right, etc.), and any other observations you have concerning tuning.
i may be interested in a project like this in the future, but mostly, i want to know if DIY ITB's have become like race headers, where you no longer need a completely built motor to take advantage of the gains. you must have some serious mods, but many street cars will see gains from a race header, and i know a lot of you use them. sure, you'll see more gains from a better motor, but will you still see some power? or is the throttle control what makes it worth it and there's no power gain? or maybe the better midrange? let's see, so post what you've done or have.

The setup is perfectly streetable. May I recommend tuning with the newest version of Crome. It's version 1.1.6 and allows user definable TPS readings as well as the ability to read engine load solely off of the TPS, which is a blessing and a half when tuning ITB's. The setup in the link is still using version 1.1.0, but is daily driven (now in an Integra) with no problems at all.
