ive been looking into injectors for my turbo build and was wondering the quality in a specific kind.

I know alot of people recommend the 60lbs siemes/motoron injectors.

What about 55lbs Siemes deka Injectors? anyone running 55lbs injectors?

im gunning for 550ish HP. Ill be running a racetronix fuel pump and wire kit. ill be using a T76 .81 turbo with roughly 10psi to motivate my stock LS1 with LS6 intake manifold, 80mm throttlebody, 85mm gm maf, and a really good tune to get to that HP level.

i suggest some injectors that have data, or at least if they don't, send them off to be tested to collect the data.

the reason most go with the 60s is likely due to the fact that 55# injectors is just at the limit on 550ish rear wheel boosted.

only reason why i ask, is cause i found a set for a steal. besides, if i hamstring myself to only be able to get to 550 i wont kill my drivetrane lol im on stock main components so i gotta keep my power level somewhat "consevitive" until the rear and trans is built up to handle it.
