Questions on fuel system design reguarding MT
OK, so i have done a ton of searching for the last week or so and still havent quite figured it out. My plan is to go for around 500 RWHP on a 13bt engine. I already picked up a HKS manifold and im thinking about using the proven PT67 or something similar, any ways on to the questions i have. Of course i want to have more than enough fuel. I already have 2 Marin 1250's and 2 720's. Of course i know this isnt enough. So what i was thinking of doing is adding injectors. 4 to be exact. After a ton of earching I still have not found this product discussed:
http://www.mazdacomp.com/intakesystems.htm
Its at the bottomof the page. It costs 280 bux and allows the fitment of 2 or 4 additional injectors. Has any one heard any reports on this? So my plan is to make new primary and secondary rails, using 720's and 1250's i have and then adding 4 additional 460's that i also have laying around. So i think i will run injectors per chanell, I will use all 4 channells and have 8 injectors. Will the microtech run all 4 channells and still be able to use the injector staging as each channel comes on? My thought is that since i will be using double the injectors that are smaller in size vs. half that are huge, it may be easier to tune a very steady AF and very smooth response? What are you guys thoughts on this? thanks for the help.

I don't think an MT will do what you want. I don't know about the LT12's...but my LT8s only has 4 injector drivers.
One possible solution may be for you to run the MT with your 4 injectors and build a Megasquirt to control your additional 4 injectors to come on when needed. That'd be a lot of tuning, but I think it could work.

sold the FD...kept the FB
Even though you'll have 4 channels, you can only seperate them between primary/secondary....more like 2 channel control.
Why not run 6 injectors with a LTX-12s? You don't need 8 injectors.
That additional injector adapter plate looks like it would have fuel atomization problems....i.e. fuel spraying on the inner walls of the intake manifold before it has a chance to atomize with the intake air.
