Joel some questions re your engine. I believe it's an EJ-22? Are you using
EFI
or have you installed carbs? ...The box on top?
Yup, it's an EJ-22. I've installed two Weber 44mm two barrel carbs in place
of the EFI. I just feel more comfortable with gravity fed carbs than the
complexity of EFI with the high pressure fuel pump and the need to plumb a
return line to the tanks and all. Not to mention the dragons that live in
the ECU that knowone even knows about. Iv'e heard that in some ECU's (maybe
not soob's - I dunno), if the alternator fails, it assumes the engine isn't
running and shuts off the fuel pump! Now I know that would be easy enough
to work around with a manual switch to the pump, but what other suprises
might be lurking in there?
Who's redrive are you using?
I built the redrive myself. I got plans from RFI for it so I know the
design is proven. I did make a few mods though. The front bearing support
is much more ridgid than the plans call for. I also used plenty of dowel
pins to hold everything in alignment when it is assembled.
what size rad is that and what is it out of etc etc.
It's a Harrison heat exchanger (GM A/C evaporator core). I have one on each
side. I was planning to have the air inlets on each side of the prop as
normal and have some reverse scoops on the sides of the cowl to suck the air
through the exchangers. Dave Bangle's setup has a radiator across the
bottom and a duct so the hot air is dumped out the normal bottom cowl
opening. That setup seems to work well for Dave and I might do something
similar. Not sure I'll like the looks of the scoops on the side of the
cowl.
