LT4 low side.
E85 conversion but have not run E anything with supercharger
D1X
I have on the shelf
LT4 high side pump
4.0 pulley to 10 PSI
I will NOT up the boost till I get a forged engine, that said I do want to dyno with E85 or at least E60.
So I show the best price for LT4 injectors $490 shipped new.
Is there a vendor selling take-offs cheaper?
I see the bigger injectors going for $3500, given that I will up the boost is it worth considering them now? Or should I go LT4 and in a year or two somebody is going to get $1200 injectors. I built many a diesel and saw injector prices change about that much as companies came in and produced aftermarket high flow injectors.
I've been waiting but so far I'm NOT convinced that 8 external injectors on the MSD is the way to go. If I were doing more than my final target of 707 WHP... maybe. For now I feel the 8 DI in the factory setup is the most dependable, most turn-key
Or should I sell my very low mile take off HP LT4 pump, do the new 12mm Lingenfelter big bore, LT4 injectors and 32% cam lobe and worry about it later....
I already assume I will need a second line and pump to the tank.

Definitely do the injectors and a JMS fpvb. swap the pully and have some fun.
We consistently put 8-10 psi on stock engines without issue, it's all in the fuel supply and tuning.
Broken motors all lead back to lack of fuel supply
