i do , use nos or any type of we direct port sysem. It is fully tunable with fuel and nos. THE BEST WAY TO GO. also use some kind of activation switch either rpm or pressure switch

 

unfortuantely my firend already bought a dry kit, how much psi should the fuel pressure be turned up? a few pounds or what?

 

To anser your question is depend on how lean while spraying. It not just turning up psi on fuel and expect to run 75 shot, stock internal and be safe on the motor..
For a 75 shot, you need to buy a good fuel management to run safely or say good bye to your motor if you just buy the kit and spray it w/o knowing what damage it will cause...

I hope that make more sence...

 

just turn up the fuel pressure 1 or 2 psi , the kit comes with a safty switch if it senses low FP then the system shuts off. A 75 shot is not that big you don't need to retard your timing from stock.

 

Yea, you can run a 75 shot, but not too much boost along with it.,

 

Do NOT run a dry kit on a boosted application, unless you are using a stand-alone with a separate nitrous enrichment fuel map. A single nozzle wet system will work just fine for you. Nitrous and boost were made for each other...I run 250hp of nitrous on a 375whp SOHC. It lives and makes great power, just make sure you pull out at least 2 deg. of ignition timing for every 50hp of nitrous you use.

Zexman, That's not a stock block is it?

Nope....Darton sleeves.....

why cant a dry kit be used? it would only be used this weekend, vafc hack is the only sort of management being used. wouldnt the box increase the pressure enough for the nitrous? it only has 2 last a 1/4 mile.

it would be only 8 pounds on the stock sir2 b16

 

When you engage a dry kit, fuel pressure increases to 60-80psi. On top of that, your injectors need additional fuel pressure to properly meter fuel under boosted conditions. This means an additional 10-40 psi, depending on what style of regulator of FMU you are using. This means you need a fuel pump that will supply the volume you need at very high fuel pressures.....70-110 plus psi. Most standard high volume pumps do not supply much fuel at these elevated pressures. As far as your justification that you only need to use this for the weekend, 1/4 mile at a time, it only takes a couple seconds to destroy your engine if your fuel pump can't keep up. Either way, if you don't trust what I am saying, go ahead and spray away, maybe you will be lucky and everything will run great............good luck...........

^^^^^^^^^^ word from the wise. heed the warning!!! ^^^^^^^^^^^^

 

will a walbro 255 fuel pump keep up w/ the dsm injectors at 8 psi?

 

a stock fuel pump will keep up with the injectors at 8psi, stock fuel pump is good for cars pushing 14lbs of booost, wat hes talking about is the supply for nitrous and boost which a stock fuel pump Ive seen before is capable of putting out.. For how long? I dont know, I know we run a sohc non vtec @ 8lbs of boost with a 50 shot of nitrous with no issues thus far, and hes probably sprayed over 15 times since boosted and before the boost he was spraying a 75 shot.. Now keep in mind his block hasnt been touched, he has 88k on the odometer and to no avail its running like a champ, sometimes i wanna believe its luck of the draw because another kid thought it would be an awesome idea to spray after getting beat by the sohc that im talking too, well 2 weeks goes by and he pulls up ready to race again, he installed a zex kit, boom their off and running sure enough when both cars hit the funny gas what happens? The kids motor **** the bed and our sohc just kept on moving..

if it was me, ona stock block id probably get a fuel pump, run about 8lbs of boost and shoot 50-75 depending on who i was racing or wat times i wanted to hit.. Enjoy

 

also, 2 step colder plugs would be used, i'll be at the shop now,
so bump the fuel pressure up a couple pounds?
and keep the same retardation i have for the boost, which seems pretty well off.
so if anyone could please give me a call on there 2 cents worth, i would really apreciate it.

want to be completely safe then yes retard timin about 2-4 degrees of timing, you'll lose some power but the 75 shot will more then make up for it.. as for turning up the psi on the fuel i might give it a a couple of lbs more just for the fact that its better to be rich then it is to be lean ya know..

all of this is bootleg, you should get a hondata or some form of engine management to be alot safer, but ive also seen my uncle tune cars running 10 second 1/4 miles with no more then a set of wrenchs.. Hes part of the older crew that want nothing to do with buttons and software n what not..

 

isnt there some kind of calculation that sets the amount of retard that should be set depending on how much boost and spray is going to be used?
