your mum has good throttle response
well i guess what i said was wrong, but my idea of running ITBs is when they run independently. When they are stuck to a plenum they aren't really ITBs.
Cos i rang ITBs with seperate pods on my 20v without the plenum and that was alot different from when it ran on the stock plenum setup.
pendulum? or plenum?
its individual throttle bodies. just means that there is one TB for each cylinder
however when most people talk about ITB they are reffering to running them open, rather than with a plenum
Does anyone have a dyno chart of before and after ITB's on a b16a2 or b18cr engines.
cheers

All you need to know ITb's make more midrange. IT will also shift the power band back 500rpm.Quote:

The key to making ITB's work on any car is airflow. If you do not have sufficient airflow and airspeed they will not produce the gains expected. Having a ported head with decent sized headers is a good match for a set of ITB's. You don't necessarily need cams but they will of course net you even larger gains.
Any gains that are achieved are all relative to the combination they are replacing.
my biggest concern would be getting cold air to them..
That's where an air box and cold air feed comes into play. Its not difficult at all. Its just that people don't do it because they are lazy. :p
yeah i know but surely that would make the majority of the gain? id do it for sure, otherwise why bother.
why bother? response
if you want gains, bang for buck - go turbo
not everyone likes FI
Could someone, explain quickly how ITB works??
