I've seen plenty live at 300hp obviously forged assembly, etc. Has anyone gone 400hp or even 500hp?

Multiple stages are fine, dual foggers. I'm thinking that lifting the heads or pushing gaskets would be the primary issues preventing this.

Thoughts?????

 

We have customers running 4-500.... The big issue is leaning out individual cylinders

 

Even with a direct port?

I think with a Super Victor it may actually allow more air into the intake and help the nitrous combust and stabilize the charge. Do you agree?

The idea is 383ci 4bolt block
LT4 heads
Super Victor or sheet metal leaning sheet metal
Twin foggers 200hp each, second kit on a 1 second delay timer

 

with spraying the large shot you need to tune the jetting on each individual cylinders. Some cars will have a hot cylinder....you will need to start small and work up to the 400. That way you can identify a problem and adjust the jetting to correct the A/F on that cylinder. The single plane will help also. We currently have a vic E plumbed with spraybars and spraying a 400 shot

Something similer to this
