I never realized how much higher the 3rd gen intake sits than the 2nd gen intake. Any suggestions on making my hood fit? Anyone run into this problem? Any certain hood scoops I should keep my eye out for?

Got the same hood problem with the 20B FB I'm working on. It allllllllmost fits without any modification. We're probably going to get some kind of fiberglass cowl and have it worked in.
looking and sounding very good.
sounds like you have a few months to stick a cage in that bitch then ...

bosch 044 pumps are rated at 200lph at 72.5 psi. 43.5 psi base and 29 psi of boost. Most injectors' flow rates are measured at 43.5 psi base pressure.
400lph=6666.7 cc/min
injector capacity=8*1680cc/min=13440cc/min of injector
max duty cycle without seeing fuel pressure drop=6666.7/13440=49.6%
Using internal energies, you need 1.53 as much ethanol to produce same internal energy as gasoline. So 4357.32 cc/min of gasoline.
4357.32*.8/(BSFC*10.5)=estimated max flywheel hp, BSFC=.65 (injector.com lists this at .6-.7 for rotary engines)
max fwhp=510.75hp
If you are running <29psi of boost you will be able to have a higher maximum hp because the pumps flow more at lower boost.
How much boost were you planning on running?

The below quotes are what convinced me to go with dual 044's.
