Another Z with Nitrous
 

Nissan 370z with Nitrous

Well, starting off with a 50 shot (definitely fell the pull), I have left everything stock, just closed the gap on my Denso Iridium plugs to .038, besides that no changes. I shouldn't have any fuel pressure problems, since our Z's can pump enough for 125 shot and below (above 51 fuel PSI)... it drops down at the higher rpms but not biggie... but still wouldn't push it:ugh2:. Already sprayed a full 10lbs bottle with no probs:tup:. I have yet to get times at the track, but will post here once I do. I plan on moving up to a 75 shot after the first few runs;). Have a unique placement due to the sound system, but we made it work without losing any seat room or visibility... just had to tilt the strut bar to accomodate the bottle. A very clean install I think. Only activates at full throttle, or I can arm it at later gears (above 2500rpm) as long as the pedal is all the way down. :driving::tup:

More pictures in the album:tup:

Wow.. respect!! I wouldnt even have the blast it on local/freeway.. lmao. Cali aint nice to tuner cars..

Don't like where you put it, but in for track times!

yea a very unique placement but pffft...... how does it go????

in for dyno numbers

I'll be hitting the track next week hopefully... Got a car show this weekend..

It was the only possible place without losing any seat room...

I actually like the placement of the Nos just not the placement of the Amp. Super Sick!

2 5 pound bottles would probably fit behind the seats on the parcel shelves

Yes they would, but I didn't want to hide the bottles either:) I like my setup guys:tup: Plus I would lose those shelves, and they are all I have left! Lol

I'd be terrified the bottle would be hitting me in the back of the head in an accident.

whats the legality of having a controlled substance openly visible to cops like this? (really i dont know)

Depends on the state..

Some states if the bottle is closed they can't do anything others are not so forgiving.

I have always just put them in the rear hatch and put and cut out the bottom of a duffel bag. So even if you looked into the car it was not noticeable at all but if you want to show it off just simply take off the duffel bag and you got yourself a show piece.

(Texas Law) Nitrous oxide when used as an oxidizer, is not illegal. Nitrous Oxide Systems are not illegal to own/have installed. They are only illegal if used on public roads/streets/highways. I would say though, to disconnect your feed line from the bottle just to avoid any problems when dealing with officers. I myself have bumped into a few cops at gas stations and they definitely noticed the bottle. They just shook their heads lol. :tup:

thats what i was looking for, thx.

It's part of the thrill! Hahahaha :D lol

Thumps Up
 

Great to see another Nitrous user come along. That's I'm glad to see that you have done your home work and know your data.

I think the bottle should have been placed differently but to each his own. Just know that when your bottle gets lower in pressure, you might not be getting all of the bottle because of its position.

If you open up that bottle, its just like a fire extinguisher. It has a hose which extents near the bottom of the tank. During hard acceleration when bottle pressure is low (even with a bottle heater) all of the nitrous will be stuck at the middle of the tank due to your position.

If you had the bottle placed where the bottom of the tank is facing the rear of the vehicle and the top end of the bottle facing inside the cab. Then when you accelerate all of the pressure goes to the bottom of the bottle where it gets picked up by the hose inside and into your feed line.

There is a reason why those brackets are placed the way they are (one higher than the other) its due to that specific reason.

I don't see any finished pictures of the engine bay other than when it was under contruction. Where did you tap? Are you running a single fogger system? Also, the placement of your bottle will not let you be able to use that thing at a track. If you are running at the track and get tech'ed properly. Track rules are if your bottle is inside the cab, your gonna need a safety blow down tube that vents outside the vehicle. Also, I hope you don't have your bottle with you alot during the day as that bottle will blow its rupture disk and vent all of the nitrous inside the cab. In its current position. You won't be able to have a blow down tube installed. If you do it will have to be a long one and your gonna have to drill through your floor.

Congrats.. Now step to a 100 shot like me:driving:

What a mouth full lol:D, first off blow down tube is installed and releases under the car... Secondly nitrous bottles have a pick up straw that not only is tilted down , but in my case is also back.. So it's at a perfect position to pick up any remaining nitrous.. Here is another point: at the time when the straw placement is actually making a difference you already depleted the majority of the power your bottle can give you... By that time just finish up what you got or refill.... I am using dual fogger system (I believe a must) and I tapped into the stock fuel line at the start with an adapter, NO splicing required:) and yes I am quite aware of the heat the bottle may build in the heat of the day. I know my stuff too:tup:

Didn't quite see the second line connected to the other part of your bottle. Sorry :o

When I asked what you tapped into, I was refering to where your fogger is at. There is not final picture shown of the engine bay hence why I was asking.

God Damn you have a nice Z, I love the custom interior.

Bump it up to a 150 shot ;)
I had that on my 350z on a stock block and it was a blast! Z's really wake up when you give them a little nitrous. Happy spraying :tiphat:

Well guys, I upgraded the nitrous jets from a 50shot to 75shot... Got a full tank of nitrous ready for Friday:tup: and a better looking gauge! Liquid filled this time:D

This is the Dynamat on the trunk bed, greatly reduces sound. And the quick disconnects I installed to easily pop out the subwoofer box:tup:

There are finished pictures there are just hard to see thats all.. The foggers are setup after the mas air flow on the elbow of the twintake.

Lets hope that come sunday you dont have any of these pictures... lol

Hey im installing nos today woot woot 75 shot and my car is turbo ed.

I think that comment applies more to Fabio than me lol

mayeb you should put the money towards the ferrari you claim to own

What kind of HP will you get with the 75 shot?

I'm also using a 75 shot in my Z, everything is ok except the OEM clutch which slips often during the shot. Did you guys noticed that to (LEGA, JC671)? Do you still have the stock clutch or some aftermarket ones?

BTW: below my bottle solution:


http://www.laptopy-asus.pl/bottle.jpg

Hey guys... Just came back from the tuner shop. Looking into getting the dynotune NOS kit for mine. 50, 75, or 100 shot, havent decided which way to go yet.

why isnt anyone mounting these in the spare tire section under the carpet. or 2 small bottles on the parcel shelf

I'm still on stock clutch. I'll be upgrading the drivetrain here shortly though. Its holding fine but definately need a lighter flywheel. Geez our cars rev slow as balls lol.

Still debating on doing the 4.08 gears as I might go Single Turbo in the future and am trying to minimize my N/A expenses that I know I'm gonna lose out on.

Thanks, though I'm surprised, my stock clutch slips many times, even without nitrous after a few hard starts from stop. Did you try the +100 shot, is it safe torque for the engine then? And I'm afraid that stock fuel pump may be to weak to manage the +100 shot. From what revs do you start the shot?

Subbed.

My clutch ain't slipping at all and right now in spraying a 100 shot and have been doing so for awhile.

How many miles on your car? Your clutch made just need to be changed already if you have a lot of miles. My car only has 8K miles and its holding fine. Now trying to put that power to the ground here is another story but I'm rectifying that issue here shortly :-)

Fuel pump can handle it btw. I spray with the TPS and mine sprays at 3K. You should not spray at anything lower.

in california the bottle has to be closed when driving on public roads, and if you have an electronic opening system, that has to be closed and off and i believe it also has to be in the trunk(doesnt have to be hidden though) but im not sure about that one

EDIT

how does the car handle NOS?

im thinking about getting a set up going as well, im aiming for at least 75 shots but i want to go 100 shots
should i tune for it as well? i assume i would have to but i never could find out

My Z has 6k miles, the clutch is slipping even without a nitrous, 2-3 hard starts from stop and that's it, it gets hot and slips. Good to hear that stock engine is ok with such a torque gain during 100 shot. I spray 75 at 2800, but have that managed via Progression Controller, so the shot is build from 50%-100% within 2800-3800 RPM ofcourse only with wide open throttle which is monitored directly by Controller.

You wrote that fuel pump handles it - just to be sure, did you check the AFR ? What is the AFR value during your 100 shot?

I had some troubles with proper AFR corection for 75 shot on the dyno because the ECU automatically pushed the throttle after shot, so I had to test it directly on the streets.

I dont understand how you guys are having problems with your clutches? I never had one single problem with my oem clutch on my 350z while spraying a 150 shot. It was just traction was the biggest issue i could only spray in second gear. I had no window switch just a wot switch and a arming switch. I know for a fact that a 370z can handle a 150 shot all day with a proper tune.

What brackets did you use to have the bottle hold on to the brace bar like that?
