What kind of aftermarket squirters would you guys recommend
with the Magnum and stock block, 50#,55#,ect.

Why and what kind (MSD,Delfi,Semeins)?

Will the 55# injectors be to big and overwork the stock pumps?

Will the 50's be to small when i go to upgrade the stock internals and push bigger #'s like (550/650)?

I'm currently not feeling comfortable with the 42's in there with the Magnum at 15-16 #'s boost and still thinking about putting the 6# lower ring on to spin her just a little harder like 17-18#'s with a safe tune

Feel free to chime in

Thanks

 

i currently run 60lb semens deka high-impedence ans i'm putting down 478 at the wheels with stock eaton no nitrous. I went with the 60's because for 20 bux more i went ahead and got them. Besides i might need them for my next upcoming "project"

hehehe

oops

 

I got the 60# injectors since they cost about the same. I know I'm not through modding yet. Even though I keep telling myself I am.

 

Get the 60's. You will not over work the pumps.

 

I also use the 60s, I forget who makes them, I got them from Sal@PSP.

I do have the 255lph pumps though.

I dyno'd the truck again today and on the mild tune it did 519/585.

 

Wow, those are some big #'s for the stock heaton,(ported or not)
you must be running like 18-20#'s boost though that thing!!!!

I still think 60's are still to big for my set up

Who's got a good deal on some 55's?

 

mine did 519HP on the eaton and a street tune yesterday, but mine is ported. I'm still looking to get some more out of it though.

 

You must have a built block with a stout head/cam combo to push those #'s

 

Unless the injectors are so big that they screw up your idle they really can't be too big (and these injectors arent that big). They don't use more fuel they just open less. Get the 60's!

 

modded with 6# lower 2.80 upper metco idler modified air box k&n filter diablo sport ship tuned for 93 octane ftvb fluidyne heat exchanger transmission cooler etc/?????? so what size injector should i be running thanks 2003 lightning

 

I would expect that you are fine with the stock injectors.
