id like to run 100-125 shot on my TPI injected 305. i have heard that the plate setup will starve the rearward cylinders, so i guess for a more serious amount of nitrous to do it right direct port is the only way to go? i found a kit that i like, but it says its for a carbd sbc, so wouldnt the fuel solenoids not be able to handle the high fuel pressures that an EFI fuel pump puts out?

heres the link to the kit, its made by NOS
NOS Sportsman Fogger Kit

if the fuel noids wont handle efi fuel pressure, if i bought a pair of noids that were designd for efi would that kit work for me?

what noids would u guys suggest if i needed to upgrade?

 

is this foreign?

 

I am not sure about the noids have anything to do with it but I think it has to do with the intake manifold differences between your TPI and a carb

 

i dont' see why it wouldn't work, so long as you had the proper jetting. Now finding a place to tap into the intake ports, might prove to be a bit more of a chore.

 

Why dont you put a stand alone fuel system in if you are dishing out the money for a fogger setup, that way you can run 6PSI from your stand alone system to your fuel solenoid and have the ease of adjustability.

 

.

saftey too.

and it'll pay for itself after a few bottles.


you only have to buy enough race fuel to keep the fuel cell full, instead of filling the whole tank with race gas.

 

hmmm, i never thought of an auxilary fuel system, is it absolutely nessisary for my application? if i can i was planning on using the shrader valve on the fuel rail as the source for fuel for the nitrous system. i am open to ideas, race gas is something i had never even thought of. if the engine is setup to run nitrous, as in correct timing, AF ratio, window module, plugs, etc and the nitrous setup is jetted correctly would 93 octane do the trick? im assuming the race gas is more of a preventative for detonation? the car will be tuned with a wideband and scanning software, to try and get things as good as theyll get.

i want a direct port kit because i heard the plate system isnt very accurate at distributing the n2o/fuel. the direct port is a little more money, 650 bux for the system im looking at, but it will be a lot more precise and safe.

i would like to plumb the nozzles, lines and distribution blocks on the under side of the intake manifold, and mount the solenoids in a hidden location as well. so the direct port kit is appealing to me in two ways, 1 beginning its much safer and it will allow me to upgrade in the future to much larger amounts of nitrous, 2, it can be done cleanly and out of the line of site

oh yeah... what i really need to know tho is if the solenoids vary for carb and efi? im thinking it doesnt matter beacuse i found this on their website...

[To supply the carburetor and the Sportsman Fogger System in carbureted applications, use a fuel pump designed to operate between 5 and 10 psi with a flow rate of 0.1 gallons per hour per horsepower at 6 psi. Fuel injected applications will require a fuel pump that flows at least 0.1 gallons per hour at system pressure. For example at 42 psi flowing, a motor that makes 450 hp while the nitrous system is activated will require at least 45 g.p.h. at 42 psi flowing, and going down the track.]

if you read the fine print, all nitrous systems from around 150-200 plus require race gas.


btw, if you're doing a under manifold setup, i hope you plan to either run a progressive controller, or dont plan on changing shot amounts too often.

the jets are right before they spray into the manifold.... meaning, you'll hve to pull the manifold to change jets.

 

hi guys, the fuel solenoids are exactly the same for fuel and carb, i've never heard of a plate system starving the two rear cylinders over here(is this a common problem?) but then we dont have that many f-bodies. My opinion(for what its worth) is that there is no real benefit to going direct port, just added dangers, an engine will only take in as much gas as it can whilst the inlet valve is open, so long as you have enough mix going in the method of delivery is irrelivent, with multiport unless all the pipes from the distribution box are an even length one will get the mix there quicker which could lead to leaning out of one cylinder(not a problem with a plate system) tou also have eight injectors which means seven more places to leak or block-just my opinion anyways, im going with a 200shot plate system and progressive controller on my 305ci, using nitrogen to keep the pressure regulated, i hear rumours that your not big on progressive controllers over there? once i get it into the 11's im gonna shove 3 hybrid-nitrous rockets in the back of it(im very serious about this one) could be the fastest f-body ever?
:lala:

 

the problem with the plate system is that the fuel doesnt make it to the rearward runners, there for they go lean cause they are only getting the nitrous and no extra fuel.

 

ROFL @ under manifold nitrous on TPI

 

shut the **** up you ****in peice of ****. who the **** do you think you are? laugh in my face pal, i knock your ****in teeth out. ive seen some of your posts, your about as intelligent as the retard my cousin has hired that seperates buckets of nuts, bolts, screws and washers for 3 dollars an hour.

 

DOH!!
ill have to read the post more carefully next time, tpi not carb
i cant see any logical reason why the rear runners would not recieve the same amount of n20 as the front though, i realise that you guys have a helluvalot more chevys than we do over here but nobody i know ever had the rear cyls lean out, or am i being blonde and missing the bigger picture?

 

so its that kinda forum eh? ill remember to try not to upset anyone on here:lala:

 

No it isn't, but with so many members, sometimes somebody steps out of line.

 

must be eating to much red meat:lala:

 

Its that he's a moron and probably couldnt install a set of injectors in a TPI without hurting himself.


See if he had a brain, he would stop to think about the immense trouble of pulling the entire tpi system from his engine each time he had to change jets while tuning the system, or to change the power level, the main one being tuning it,


And im certain i've got far more experience and talent when it comes to thirdgens than you'll ever have SLPwannabe, i've had to post more times on these boards to correct people, trust me you're the dumb one here.

 

Give it up. He asked a question, he got an answer. just because YOU wouldn't do it, doens't mean it is dumb, or not doable. If you would like to explain where else you are going to install a fogger system, on a stock style TPI setup, I am ears.

and i will also add, the NOS actualy SELLS a kit for instaling under the manifold. I guess they are idiots too.

 

not to mention, there is ZERO "tuning" of a nitrous kit.

you have a known amount of nitrous.
a known amount of fuel required for that nitrous.

so you just jet for the max of whatever you intend to spray, lets say a 200 shot.

you then use your progressive controller, like the nitrous mastermind i mentioned above, and dial back the nitrous... so you start out with a smaller shot..

 

because of the crappy weather we have over here some people adjust the size of nitrous jet in the winter months to compensate for the bottle pressure/temp and refer to that as tuning, we also jet all our kits at the solenoid(makes changing them easier) and gives a slightly softer hit

 

1st mrdude, using a progressive controller is known to considerably put extra wear on the solenoids, for most thats enough of a deterrent not to try and run it to limit the system that much.

2nd dewey, its been done reasonable, annular discharge nozzles into the bottom of the runners aiming straight in where the inlet of the baseplate is, im quite sure you could also do it below the plenum into the top of the baseplate only requring removal of the plenum for work on it, and if you've done any research at all on the under manifold system it requires complete nozzle changes to adjust it, does not use normal jets like a typical nitrous system, and that isnt a specific TPI kit, its a carb'd universal kit, i didnt say an under manifold system was stupid, i said it was on a tpi due to all the trouble of disassembling it to adjust it any, it would actually be a great idea on an LT1.

 

i know the older style us solenoids were fitted with rubber seals and were subject to wear, we have tested new nx/zex/nos and ny-trex solenoids on our progressive systems and they all made it through with shining colours, 3 hours continual pulsing only made the seal better

 

NX approves their 'noids for progressive use. it wont void their warrenty.

 

nx, nytrex, cold fusion- all the same solenoids

 

Back to the subject at hand....

Why bother spraying 125hp when you have a direct port?

Don't be gay!!!

And a separate fuel system?!?! Why? You don't need it. It doesn't make sense. While your at it through a set of oliver rods in there for good measure. Cause that makes just about as much sense.
