is 19lb enough????

[MonkeyMan]

its better to have too much fuel to play with than not enough.. I have 19lb injectors and my setup is nowhere near yours, and according to the dyno, they're more than sufficient for now.. I have the Miller chip as well and we started with a preloaded base tune for 19lb injectors and adjusted from there.
I'd say 19lb'ers are a no-brainer for that setup - after spending all that money on engine parts, it would be a crime to not spend a little more to fuel it properly.

I honestly have no idea what kind of power I'm going to get out of this thing. But I'm very excited!

Alpina made 200ish hp from standard injectors.............i would use what miller suggest

I have a W.A.R. chip and I believe brody loaded it with a tune for 19lb injectors I have to plug it in and check.

And if I am not mistaken, a stock FPR will be enough right?

[ForcedFirebird]

At 90% duty cycle 19lb/hr injectors are good for about 200whp pending drive-train loss, they will be fine.

While tuning a Motronic the injectors were intermittently static with a b25, ebay headers and 272 cam.

You will need a custom chip, really, for the tune to be correct.

288 cam as well

What? I thought 14lb injectors were already at 100% duty cycle with just a chip.

My evidence is that they aren't maxed out if the injectors are clean.

You'll find out for certain when you have the car on the dyno for tuning. The work you've done on the engine will have slightly increased the mass flow and tuning for that combination will be necessary.

You won't even need 19lb injectors with that combination. The stock 14lb injectors should be more than enough.

I'm sorry but I absolutely disagree with this.

adjustable FPR and bump it up a bit?

[delatlanta1281]

19lb is enough.

MaxSil 0.50 over pistons, VAC stage 3 head, schrick 288 cam, hone extrude manifold, miller MAF+W.A.R. chip, header back. should i go any bigger than 19lb with my injectors? any P/Ns?
