75 Direct Port shot w/o fuel cell

andy

I was just wondering if it would be safe to run a 75 direct port shot without a fuel cell, and instead using octane booster in the gas tank... not to mention i dont see how a single fogger nozzle can run a 75 shot no problem but everyone says a 75 shot with direct port will result in engine failure.

.direct port 75 shot wet will be iffy.........if done right i think it'll be safe.

.i ran a 80 shot from a single fogger nozzle. its not hard at all. just have the right jets, and make sure you use a good fogger nozzle. i'd recommend a NOS fogger-2 nozzle, with NOS jets. and besides, the most important part of the nitrous is enough fuel. and trust me, with 50+psi fuel pressure on the QR, you should be fine under a 100 shot.

a direct port for a 75 shot would really be a waste, imo. unless you want to hit each cylinder with a 75 shot, lmao. then you're just plain stupid.

.lol, no i dont plan to run 75 to each cylinder... i had a single fogger but bought an intake manifold welded for direct port, and recently decided to install it.  I looked at the jets and it was 22 nitrous and 18 fuel if i remember right, which i'm confused about, because i've heard its a 110 shot from one person and it calculated to be an 85 shot according to an online calculator... either way i'm dropping it down to 18 nitrous and 12 fuel probably... i ran a 75 shot on my single fogger setup for about a year and i never had any problems, so why can't i with a direct port system?

.well, first you need to be sure exactly what type of jets you are using.  NX and NOS jets are different. so thats why you are getting different HP numbers.

if you already have a intake manifold tapped for direct port, go ahead, but remember that you have to buy 4 nozzles, 8 jets (4 fuel, 4 nitrous) a splitter for the braided lines, and all that braided line.

the only thing i'd be worried about is if the stock fuel system can push all the way to the fourth fogger nozzle. that part might get dangerous. see, there is no way to really tune for that because of the returnless fuel system.

but then again, if your running a fuel pressure saftey switch, you should be fine in case the fuel pressure drops suddenly.

btw, where are you pulling the fuel from? before or after the injectors?

.btw, i don't pretend to know everything about a nitrous setup. you should PM pituala (thats his sn here) if you have a question. he's a great guy, always willing to answer a few questions, or to make you a custom fuel rail

.I'm pulling fuel before the injectors which i know is stupid... i plan on getting the HPA fuel rail before i start running the nitrous anyway though, which has a return fitting on the end of it.  I would run the walbro fuel pump but i hear a lot of stories of it cutting out on people as well... so i'm kinda stuck here.

.pituala makes fuel rails for the spec v you know. thats what i used for my setup.  and im sure his turn-around time is better then HPA... i'd PM him. he knows a ton about nitrous on a spec-v, and exactly how to run it.

but if i was you, i'd run it the same way i was running it- which was the same way he was running it. 80 shot through a single fogger nozzle with a fuel pressure safety swtich, and a modified fuel rail with fitting. no need to go to return fuel line for anything under a 100 shot. just remember to set your timing back to stock (if you advanced it at the dealer), and run a colder plug. that almost got him into the 12's, and it won me a great deal of money, if you catch my drift

.the fitting on the end of the fuel rail you're talking about is the return line fitting... thats what i'd use to hook the nitrous line to, but i did PM him, thanks for your help.

.not a prob.
