LB7: 30% over injectors.

[Bustedknuckles]

I'm going to be needing injectors soon and i'm trying to decide if 30% over injectors are worth it or should i just put stock ones in? I dynoed 519/9?? and i hear that's getting into the danger zone for lb7's and i have no desire to build the engine....

They are a pretty good option for some extra ponies. There will be a noticeably difference between those and stock. Exergy usually have them on special pricing so they would be somewhat affordable when compared to stock.

my 30% ddp nozzles did 860 recently with moonshine tuning fwiw

30 overs would be a good choice for you. Let us know if we can help.

Well I picked up a set of used 1500 mile injectors off here and am sending the nozzles to extrude hone to get honed out to 30% overs!

Injector tips are supposed to be here today and I'm putting them in tomorrow night. Updated tunes are ordered from ATP. I cant wait!

Let us know how you like them. I've got of 30% nozzles in my basement I need to install once I get some other things done.

Haha, been there WAY to many times before.

Glad to hear you got them in. Hopefully everything went fairly smooth and it's running good.

Let us know if it made a difference but yet your mileage didn't tank.

I haven't put any miles on it, hopefully at lunch time I can put coolant in and change the oil and run it. It didn't go so smooth, 2 injector cups pulled out and I managed to drop the bore brush into the cylinder 0_o. This is the brush

 

[Bustedknuckles]

Alright I put a few miles on it now! It definitely runs a lot better than it did with worn out stockers, I cant wait for my new tunes to get here now! Last night was just a fail between 2 cups pulling out and dropping the brush into the cylinder but at least my truck wasn't even down a day, pulled it in after work and backed it out at 3:30! The best part is the ticking noise that's been driving me nuts is gone, it was caused by the passenger side injectors not being tight enough and the coppers not sealing. The worst one was blowing combustion up past the body and had ruined the o ring, apparently 37 ft lbs isn't enough....
