It all works now. Each kit can be fired independently or together.

That's awesome. I have thought about a combo like that, but with more nitrous, lol. Just dreaming on my part, looks good. Keep us updated with track times.

any reason you went with 2 kits vs a progressive with a larger single?

I wondered the same, but with my limited knowledge I didn't want to question it. From my studies on YB, sometimes a large single on a progressive is easier and safer to tune. My guess is that the 200 shot is just the beginning though.

way way back in the day when we ran the nitrous car we ran 2 kits and had 3 on the car... its honestly more nitrous than that 450" small block could actually use. with the new plates out like the sledgehammer and the stinger you can spray a metric load on a single kit with a progressive.

with my car im going to be running a banked soft line fogger. hopefully i can use that to limit how much i try to spray the house down on the stock block, but being banked i think i can bring it in smooth enough that it doesnt make the car super violent without converter tricks

I have never been a fan of progressive hits. I sprayed a lot of nitrous on bikes (busa,zx12) when the solenoid was rattling away it allways felt like a turd
until it was all in. Went to 2 smaller kits and loved it.

The car is giving me the same impression. I don't have a grid,so all the timing comes out,50 %.5 sec feels like it goes pig rich and
takes time to recover (very conservative tune does not help) right now 2nd kit is .050n/.047f pulling 5 degrees.
Think I want to try .053n/.048f pull 4 degrees, 60% .4 (pump in the tank 92, stand alone has 110)

yea those jet spreads are screaming pig rich! shocked it honestly doesnt lift ring lands with that much fuel in it lol
and not having a step retards will make that really screwy to tune down low

id probably lean both kits out a good bit.
if you are under timed in the 1st kit you can go stupid lean and not hurt anything.

going lean on nitrous wont hurt anything if the timing isnt aggressive. if there is no fuel to burn there is no fuel to burn.

RangerJoe · Dec 20, 2018

@srtthis is there a ratio to shoot for when doing the spreads? I know everything is different depending on fogger, vs plate, vs efr single nozzle, but what is the general consensus?

Joe

srtthis · Dec 20, 2018

most nitrous guys shoot for a 7:1 ratio... those spreads get pretty big when you have higher fuel pressure.

Gear grabber · Dec 20, 2018

Just to be clear,i have a 3 step retard. I am pulling 3 degrees on the first kit (.041n/038f)
5 degrees on the 2nd kit. (.050n/.047f) Fuel pressure from the stand alone is 5.75 lb. (carb.)
If I can borrow a jet holder and .073 jet,i will flow the fuel side today and bump the spread to 8 or so.

I guess that is what I don't understand. Its obviously not a 7:1 ratio of the jet size, so what's the relation? 7:1 nitrous pph vs. Fuel pph?

correct... PPH

Gear grabber · Dec 21, 2018

Borrowed a flow tool. Will set pressure and start pulling fuel jet out.

Sweet set up man,what’s the rest of the car look like?

Thanks ! So far all efforts have concentrated on go. The car very much has a junkyard dog look to it.
As much as it pains me to spend money on ''pretty'' the plan is to get the car into paint in February.
