So im going to end up running a 125-150 shot of nitrous i was just wondering how it would work and what size will be good. Or what size are most of you ruinning.

 

It would depend on your engine.

 

Well its a 355ci w/ 10.1 comp
Aluminum Heads 64cc 190cc intake.
1.6 rockers
Cam is a 3500-7000 rpm, dur 244*/254*, lift .510/.533

 

Probably around 4000-4500 RPM.

 

So get one that would start at that rpm. Isnt that a little high. Just wondering.

 

Hard to say without knowing what the powerband of your engine actually looks like, but it should be somewhat in line with that cam.

 

Thanks Apeiron for the info.

 

Might want to get some more opinions before you actually buy one.

 

Nah, it's more fun to fly by the seat of your pants like that.

Gears, weight of car, engine displacement, etc, all play a major role in which converter to get. If the engine starts to make decent power at 3500RPM, then if the converter stalls to 4000RPM you're sure to be in your powerband when it hits. That cam means you'll be running down the 1/4mile at 4000-7000RPM through all gears. Sound right?
That cam might be a smidge big for those heads.
