Another few weekends pass, and more progress to report. I was able to swap
in the 80#/hr injectors, and they calibrated perfectly. For those interested in
saving a few $$$, you can buy Siemens/Deka 80# injectors directly and still
use the LU80 injector data.
With the larger injectors installed, I've run the motor up to 5000 RPM and am
making 10+PSI. Everything about this combination feels great - AFRs are still
in the low 11's (more fine tuning to do), and over all streetabilty is fantastic.
I'll drop the tank this weekend and swap in the new TI Automotive pump. Its
going to be rainy here all weekend, so might as well make the best of it.
Once that's complete, I'll get a few full-throttle pulls done next week and see
where things land for peak boost. Plan is to set my shift points to ~5800RPM
and see how the airflow and IATs look in the datalogs. This is one of those
times when I wish I lived out in the middle of nowhere - its a bunch harder to
find safe places to do this in the outskirts of Boston.<g>
This all of course has me thinking, how much boost is safe for this
combination? I'm wondering what others are running on their street cars
on pump 93 octane?
