60 vs. 80 lb injectors

[Backside180]

I'm moving to bigger injectors. The siemens 60 lb injectors will be fine for the power I am currently making. However, I notice that the 80 lb injectors are only $30 more expensive for the set. So... I was wondering if I should just go with the 80 lb injectors and that would leave me some flexibility should I decide to turn the boost up more later.

Are there disadvantages of the 80 lb injectors vs. the 60 lb? Idle quality comes to mind, but perhaps I will have to deal with that on either set?

Thanks

i have no experience with the 60s but after a little screwing around with short pulse i got my 80s to idle fine in a bone stock lq4. ... so why not go bigger.

Could you send me a copy of your tune file with the 80's?

I had a set of Siemens 80's. We maxed these 80's out at 791. My car idled and drove fine.

Might want to look at the rest of the fuel system... I have made over 800rwhp twice with 60's, and a local friend of mine made 852rwhp with 60's with increased base pressure. I have made into the 900's rwhp with these 83's several times easily.

-edit- just the saw the very dyno un-friendly th400 in your sig.

I can only read partial sigs at best
