Tim240z Posted August 24, 2003 Share Posted August 24, 2003 what is the benifits of a two stage FI set up? I would imagine that when running huge boost, and have to run huge injectors, you could do so without losing low end driveability. One set would operate at low boost (low rpm) times, then the second set would come on as the first set get past their operating limit.

Guest rick458 Posted August 24, 2003 Share Posted August 24, 2003 they don't look to be mated up it appears the forward set is missing its plenum whereas the rear set is not Quote Link to comment Share on other sites More sharing options...
j260z Posted August 25, 2003 Share Posted August 25, 2003 the new sport bikes are running a setup close to that. the big problem the bike manufacturers were running into was that the rpm range was too big for one set of injectors to be able to handle the range. like tim said, they use one set of injectors so they can keep a nice smooth idle and low throttle response and then when they get upto around 9000 rpm the other throttlebody injectors come online. i'm pretty sure the show i was watching on it mentioned that at the higher rpms the injectors were firing about 400 times per second!!!

Cruez Posted August 25, 2003 Share Posted August 25, 2003 Hmm, that makes the second one I have seen.. My brothers turbo 240 is running a setup like that.. I wasn't exactly sure why the builder did that, I know that car was running 21 psi when he originally built it....He is using an older Haltech system to fire it...
