Here are the nitrous install pictures....Gray

Interesting bottle location.
What did you do with the switches inside the car?

Do you have a RPM switch?
Do you have a button or a WOT switch?

Am wiring Tps switch this weekend...for now spray with button...I spray in 3rd and 4th so no real need for window...do have fuel pressure kill switch...also have it lined for a 10# botttle in car.....will go back to airstrip tonight with several full bottles...#'s to follow....Gray

Since the bottle is up front by the motor is there a need for a bottle warmer? Any problems running a dry system?

Vetluver

I notice you have your tank next to the AC exchanger/radiator. It gets pretty warm at that location. Do you have a pressure gauge to check bottle pressure. If your tank gets too hot you'll excede the recommended bottle pressures ~1000 psi. Instead of getting a 35HP shot you'll get a 50+HP shot. I'm not sure that you won't overdo your injectors and reach the dreaded lean condition. I guess there's no need for a bottle warmer huh. :p

One other point, a full bottle has way more pressure than one that is half full unless you are able to increase pressure by warming the bottle. Watch out for what I call a HOT bottle, it'll cook your valves to a nice black color. Ask NOS about a purge valve, it adds a bit more safety.

Can you get a picture of where you tapped the N2O injectors into the air intake tubes/ plenum? Also how you end up triggering the N2O. Are you using the TPS switch that is on the engine or are you going to have a mini switch that is triggered by throttle body butterfly valves (if there are any)

I appreciate your experimentation, I love nitrous. Your ***** are definitely bigger than mine, or you are way richer than me. SBC motors are way cheaper than $30k.

Rob,

The bottle is installed prior to a run...however, did some stop and go and the bottle temp never exceeded 115F..its wrapped with numerous layers of thermotec. I also have a line hidden but avaiable in the car that I'll use as weater heats up.

I well understand pressures over 1000#'s and the danger...believe me...usually there's a pressure gauge on all my bottles.

TPS this wkend I hope ...for now activating switch(the orange safety switch in pic) and in car trigger switch...on at 4000rpm's in 3rd thru the shift and 4th thru the lights...

The nozzles are in the snorkle tube about 2-4 "'s from air box...using twin .024's now which is just under a 50 shot...much more on our cars though due to cooling,effect etc. as you know.

I'm not sure about the net worth or testicular circumferance issues(you're the urologist after all)...but...as you know...no fool like an old fool...Gray

hilsman, hotrodder extraordinairre!

BenzoAMGpower

so your spraying a dry shot str8 into the airbox and through the supercharger? I wonder how that will affect teh teflon coating on the s/c rotor.

Im thinking of running a 75shot wet and tapping the spray nozzle into the metalic splitter peice taht comes from the intercooler under the s/c to teh intake manifolds taht way I am not spraying into the s/c. Let me know about your thoughts on this!!!

hilsman

In regards to wet system post supercharger....two potential probs, although in theory, I like this approach the best of all. You'll have to take into account that fuel flow will be a bit harder to factor as the nozzle will be under boost pressure....also there is a real risk of puddling and the dreaded backfire and all the usual wet system isssues.

As far as N20 on the teflon there should be no proibs given the extent of mix with air pre s/c, the small shot, and the very nature of teflon to resist corrosion (what little factor that may be in regards to N20 in this application).

The motor could easily handle a 75 shot...FYI the folks at TNT are working on a pre s/c application which they feel is safe..e.g. s/c bearings/teflon issues. Good luck...Gray

Hilsman,

If you get a chance could you take another picture of the car with the bumper and grill back in place?



thanks

OMG..... E55 with N20..... Insane!

hilsman

Bumper and grill did not have to be moved for install...hood is just up....

BklynBenz

wow thats awesome, cant wait to see the numbers

DerekFSU

Numbers? Let's see those 11's!

What happens if someone hits your car in the front and explodes the bottle, are you getting a fire control system ?

BMWEATR

OK this might be a dump question but why 2 selinoids? wouldn't one be just fine?

hilsman

If the bottle was puntured it would simply release the N20, if crushed the pop off valve would relieve the pressure rather explode, a fire would result in the same scenario..N20 in and of itself is not flammable.

I use two solenoids, two lines and two separate nozzles for efficiency and better N20 air mixture in the two air boxes.... Gray

SSpray

When I spray dry, I like to do 2 solenoids in-line and then ‘T’ (if needed) with 2 lines going where I need them.
That way there is a bit more safety, incase one solenoid sticks open, and it also keeps the nitrous flow even though both jets.

miroj

N20 at atmospheric pressure cant explode or it cant explode at high pressure ? I dont know why anyone would think this one rule applies to both conditions.

hilsman

Miroj,

You are correct....I was talking about the pop off valve saving the bottle from exploding not the N20..Gray

medici78

If the teflon is anti-corrosion, wouldn't it still be safe to run a wet shot? There is a wet kit available for the Ford Lightning, which is also supercharged.

hilsman

I know at least on manufacturer who says a wet shot is OK and is working on an application ...they were concerned about the bearings moreso than the teflon coating...Gray

medici78

Is it a universal application for supercharged vehicles, or for a specific vehicle?

Another question: Where did you install your wideband O2 sensor?

hilsman

TNT is looking at an E-55 wet system....I installed the bung on left(facing engine from front of car) exhaust pipe just to the side of the existing precat 02 sensor....however on my car the tailpipe readings at WOT are less than .5 different(lean) from the precat readings.

medici78

Oh, man, that would be awesome if they made a system specifically engineered for our cars. I'd scoop that up in a second. Basically getting the gains of a $10k pulley, ecu and header package for a fraction of the cost and all the while you can remove it and nobody would be the wiser.

On the O2 sensor, would you say the wideband is more accurate in your location than the tailpipe readings? When you say tailpipe, was this on a dyno?

I highly commend you for sharing your info with the community. I'm sure I speak for many of us that we are very impressed by your pioneering efforts with nitrous on these cars.
