I am rebuilding me a 355 LT1 with forged internals and I noticed the Nitrous Express LT1 Maf System can spray up to 300 horsepower, but is it safe to spray anywhere between 200-300 shot of nitrous if it is not a direct port system? Wouldn't some of the cylinders lean to much and blow my engine even if it is forged. Thanks for any info.

 

We have customers spraing this much through a single nozzle.Howevcer I like to recommend that a directport is a good choice for anything above 250.I prefer the direct port for 300 but you could do it with the maf.

second that, dave is right as always.

 

I run a 300 shot through my TPIS Miniram intake. (almost identical to an LT1 intake)
No problems yet, I've been doing it for a few years now. It suprisingly provides good even distribution too. I run two stages which you can see on the graph.

The MAF kit is much, much easier to install than a direct port, but I'm sure you would be happy with either.

Happy spraying!
