Black Knight RX7 FC3S

What company that make NOS (nitrous, N2O, Nitrous oxide, nitro, or wat ever) kits are the best. Cuz I want to look around and find the best one.

scathcart

NOS or Nitrous express.

None of them are "great" by any means though. I'm looking into making a "great" kit, should be available sometime after christmas.

dr0x

Nitrous Express.

scathcart

Do you have personal experince to base this one, or is this heresay?

The new Venom Kits come with a palm pilot to program them with. They have three different modes.

Drag mode - control the amount of nitrous power at wide-open-throttle (WOT).

Linear mode - Program the throttle angle at which the
nitrous system activates. After the system is activated,
any increase in throttle forces more nitrous to your motor.Feels like a turbo system!

*Timed mode - similar to linear mode, only the amount of
nitrous is constant after activation. Also adds a timed
feature. Great for nitrous turbo setups

scathcart

Venom? On a rotary?
I don't recommend it.

Everything you list can be had more reliably with a progressive controller and a wet setup.

Nitrous Express has better solinoids while NOS bottles and valves seam to flow better and respond better when you hit the button...

The best way is to price out individual components from the different companines get the features and parts you need...

That is true. I saw the Venom kit, but didn't have all the details.

scathcart i got a question kinda off beat but since u know alot about nitrous on a rotory. how much of a dry **** can a rebuilt rotory take on a normal basis without blowing?

fastrotaries

i've had several of my friends NOS solenoids clog up on them, while the guys with the NX systems never had any problems. We all get our Nitrous from the same distributer.

I've run 100 psi on my 90 N/A dry with an upgraded fuel pump. Ran me a 14.2 at the track.

Tec

Do they change there oil?

Even N20 filter screens need to be cleaned, I check mine every 70lb or so. did your friends use teflon tape or past on there fittings?

If you could put together a kit that was very easy to install and understand, you would be my hero I'd love to put about 100HP of nitrous on my N/A after I get my streetport, and have been researching "kits" for a while, but me haveing no experience with nitrous, it seems a little overwhelming. If you could put something together that was easy to install and understand, I would buy one for sure.

holy **** NOS FC3S what where all of your mods?? beside the 100 dry shot?? what kinda fuel pump was it?

fastrotaries

yeah from time to time. but the NOS brand ones seem to require it more often. i think it was paste that was used.

scathcart

I have not had any problems with the NOS brand ones clogging after 160 lbs have flowed through them, and I run two NOS solenoids, and two fuel solenoids.

I also run filters on both the fuel and NOS side.

scathcart

I'm kinda curious about this myself, considering he doesn't even know that nitrous is measured in hp jettings and not psi jettings. The bottle is pressurized to almost 1000 psi, not 100.

on an NA, with mods... no more than 50 dry if you want your injectors to last. The fuel system is already pathetic on these cars... why would you try and push that?

The wet set-up I am designing will be much, much better, in every way.

scathcart

Tell you what... I'll one up that and give you an easy, hidden installation, everything you need for fueling, and wiring to meet your exact needs, idiot-proof instructions, preset jetting charts for safe tuning, included jets for 50, 60, 75, 80, 100, 120, and 150 hp levels, a system that properly mists in both nitrous and fuel in a fog far superior to single foggers and dry injection, and a couple extra fuel-side parts.
How does that sound?

I am sick of having these "fit all" import kits, so I am making a kit to actually fit the RX-7.

dr0x

Well, I personally will only ever run a wet kit. I know a dry kit can be made to run just as safe. Just personal opinion I guess. So... Lets sa N/A's make 130 to the wheels, then that 100 shot gives you another 85 to the wheels. You are telling me with 215rwhp (and who knows how much tq), the best you can run is 14.2?

scathcart

How about the fact that a 90 13B makes 160 hp at the flywheel, and around 190-200 with typical mods.

Add 100 hp through the injectors, and we are at a 112% duty cycle for N/A 460 cc injectors. How long do you expect the injectors (and the motor) to last at those duty cycles?

So, tell me... what size injectors are you running? You must also be running these sizes in all four injectors slots to be running properly with dry, so you must also have a form of fuel management such as an S-AFC or haltech to prevent running extremely rich. We have also gone above the fuel supply capabilities of the stock fuel pump, and so now the car is running rich at idle and low load, so he must also have a aftermarket fpr.

100 extra hp and he only runs 14.2... this sounds like a load of BS... especially when he didn't even know jetting sizes aren't measured in pressure.

I use COMPU-CARS components

GLHS

If he was running 100 shot what would his time be then? Faster than 14.2?


I ran a 75 hp dry shot, NOS brand. I think the number on the jets was 24 or something... I heard that was a measurement of the orrifce size of the jet.


I had no problems with 75 dry shot.. But I want more...


Wait til I make my system..
it will be a standalone setup, with all fuel in a separate system, with its own high volume fuel pump, on its own injector/s. I may even make a separate fuel tank.. with race gas in it..


wonder if the rotary would handle 250 shot.. or so?

*bows down to scathcart*

When do you think you can have these kits available, and you have any idea how much $$ you'll be asking?

Detriuch

iTrader: (1)

yea compucar make GOOD kits. im just wonderin how much a basic rx7 with a dry can hold?. 50 huh? is that without fuel pump and changin out injectors right?

banzaitoyota

I added a Walbro pump
