Type 1 sotck EFI from Mexico ..injector size
Hello-
Rough rule-of-thumb for injectors: 1 lb/hr is good for 2 hp.
On my ~220hp engine, I have a 30 lb/hr injector on each cylinder. According to my computer, the maximum duty I've hit with them is about 90-95%, so the math seems to work out well
.
Take care,

Shad, now that I know I have to resort to Hydrolic lifters to use the Mexico EFI, what type 1 conversions do you know of or recommend?(Jake or John any help please)
I want to make sure that the 1,776 engine is both reliable and "peppy"... I figure I could get 13lbs/Hr injectors and that would get me to what I want out of the engine, and if I stick to the EFI from say a VW Fox, or a Rabbit of the same size engine I would be more or less in the field. What items am I missing from a setup for type 1?
