here it is


331 ftlb's @ 3800rpms

312 rwhp @ 6100rpms

i messes up - my shift light was set to 6100rpms and that is when he lifted off the pull :nonono:
A/F was between 12.9 at the bigining and 12.3 at the end of the run. what is good A/F to be at 11.5-12.5
:banana:

i have a vid but it says it to mang mb's? i can email to anyone that would like to post it for me~ anyone?

12sec67, those are good numbers! You could probably get more out of it with a little less fuel, most n/a sbf's usually put down the best numbers and the flattest curves if you can get em at a constant 13.2 ish, almost always between 13 and 13.5 though depending on your combustion combination, plug temperature, etc your 12.9 and 12.3 are pretty dang close. maybe try about 2 sizes LESS secondary jet.

edited - i meant smaller jets, i accidentally said bigger

my best torque was at 3800 w/ 12.6 A/F

my best rwhp was at 6100 w/ 12.3 A/F

1 bigger/ smaller jet size lowers/raises the A/F how much?
