Can I run 83# injectors (A1000) and strait meth and cover 800rwhp, and still be safe? 6.0L- twin 62's. Check sig

I am going to say no... I am running twin 62's and 160lbs injectors at 60lbs fuel pressure. You might be able to get away with 96's but it would probably be 100% duty cycle. Not good if it fails. I would say 120lb injectors minimum if using E85 and I would use two fuel pumps. I use two A1000's. The second one kicks on at 4 psi of boost. I only have 650 to the wheels.

The meth wouldnt "add enough extra" to the fuel system? It would be like two pumps, and more fuel??

It probably would be okay if you were going for 700 to the wheels but I don't think it will still be enough for 800. I could be wrong. I also have meth injection but I am using a 33%/66% kit.

I made 811 on 75psi on 80lbs siemens at 105% idc. So 750-780hp your be at 100%idc.. that was ith a 88mm turbo on a 6.0.

Those new high impedance 160lbers are sick, grab 1000bucks and ge those.

Generally avoid meth injection with e85. There is little to no benefit of running meth as a charge cooler as e85 does just that. Just another system to fail and leave you broken down. Sell your 80s and get the right injector and pump(s).

I've been from 120s to 160s to 210s and now 250# injectors on my setup. I'm a believer in "over building" the fuel system as it's the engine's life line and I don't want a system that's running on the ragged edge at max power. You'd be asking for a melted piston or broken ringland.

So 120's? 160's?? One A1000? Two? Belt driven pump?

I'd recommend a magnafuel 4301 and 120s for your goals. You'll need braided lines/an fittings/ rails etc.

For the money, would it be ok th run 160's (high impedance) with a magnafuel 4303? Also, is a -8 big enough for a feed line to the y block? (-8 from and back to tank) Is on -8 vent big enough?

The 4303 and 160s would be fine. I'd recommend at least a 10an feed and a 12an would be better so that your fuel system would be ready to support more power in the future should you choose it. 8an vent will be fine.

With 2 meth nozzles HO meth pump and 2 255's you should be fine. It's always good to have a safety margin tho. I've pushed 68lb's @62psi base to ~1000+ on gas with 4 meth jets

Done a few cars over 800rwhp on 83lb injectors with e85 and no meth, ditch the a1000 tho

Ok. The magnafuel pumps has -8 ports in & out. Just put larger fittings on, and run the larger lines?
