Here is a question.
Quote
-190 lph Walbro
-630 Seimens Injectors
292 rwhp, enough fuel (aka reasonable duty cycles for the injectors with sufficient fuel for a good AFR), still runs good!
This is on a 1ZZ .
So is our stock fuel pump better than the Walbro 190 lph ?
Is the stock unit ok for the 440 cc injectors ?
