Well, I've not really posted about this yet. But I've added a nitrous setup to my ranger.
For those of you who don't know my background on the subject.. I've not going to call myself a "guru" about nitrous. But ...I have been using it and designing / engineering direct port kits as well as single injector kits for a few years now. I've learned a lot from Tevor Langfield (Wizard of NOS in england) and a lot from Denny Hanson at www.racetested.com
Lets just say I know more than the average bear.
There are so many pre-concieved ideas about nitrous. And nearly all the ones I come accross are based on faulty science.
"instant on" "stages" ect... and the fear of using nitrous is a real killer of the product. So many people think they understand how to use it.. but yet have no clue whats actually taking place. I've learned from the best and am going to take this 4x4 daily driver ranger into the mid 14s w/o any fear or worries of longevity of the truck.
As far as the ranger goes. I'm working with Denny and we are developing a low shot size system for street car use. I have several advantages in they kit we are designing.
1) No purge needed (nearly doubles the amount of nitrous you can use. Absolutely no wasted nitrous!)
2) Safe for the stock motor and safe against induction backfires
3) Ramping the shot size based on time or rpms (it's not a fixed hit and not "stages". Neither are "window switches needed")
4) Lower bottle pressures. (950psi)
5) And most important. Keeping the nitrous dense (liquid) until it reaches the injector.
This kit we are working on is a dry kit. I'm adding fuel via the tune. Shooting wet in this intake is dangerous from two points.
1) Fuel drop out means a *possible* lean and unequally distributed (cyl to cyl)
2) Induction backfire (these are commonly mis understood. But sufice it to say we don't want to blow off a complicated plastic intake!)
So far I'm shooting a 35 shot to get this lined out and the tune adjusted.
Once Fred at rouge performance gets this done I'm stepping up to a 50shot to see what the fuel system can handle. If it does that well I'll step it up to a 70shot. That's going to be my limit for this stock motor. At that level I may need to upgrade the fuel pump and filter. Just not sure til we get there.
I still need to update MY NITROUS WEB PAGE
with new pictures of how I'd configured everything. Just know this. It's 100% hidden
. I have a 15lb bottle and you can't see it. Nor can you see it even with the hood open. Stealth...
Here is a wideband datalog of the current "Henson" tune I have. Both off and on a ramped 35 shot. What a joke. Last fall I told him I thought it was going lean up top. And boy was I right! (Fred is fixing all this soon)
