i have a brand new engine combination that was built similar to a engine on CHI"s web site but its alcohol injected there motor made 785 hp with a meth dominator.
I went to the chassis dyno yesterday and about died
my combo is 410 inches , chi 3v heads 218 cc runners 338-238 cfm
775 -757 lift 266-274 @.050 108 sep 14.0 compression 240 lbs cranking compression 4.0 stroke 6.0 rod vacume pump ect.......
first pull 24 degrees timming base line nosed over 5900
second pull 26 timming , gained 30 ft tq nosed over 5750
third pull 28 lost nosed over 5750
pulls made from 50 mph to 110 mph average time 1.5 seconds
egt was 1005 to 1070 max
a/f ratio 3.8 idle 4.83 durning run highest, water temp never climed and
CHI's motor ran best at 5.3 to 5.8 a/f
I guess what Im getting at my jets are #37 with 0 1/2 pump
I tried at 94 return pill base line and tried #90 and motor lost power
'so it didnt like anymore fuel at all
with the a/f ratio off that much and motor nosing over at 5750 rpm is it way fat?
the dyno operator said it would be 25% loss from flywheel to rear wheel hp with puts it at 622 hp at 5750 rpm. but dies from there.
the motor would physically turn to 6800-7000 but made less power from 5750?
made 7 pulls and water temp never got off 140
egts were 1007 to 1070
I need some help please
