I have a stock 454 BBC with 2 bolt mains backed with a Turbo 400 trans. Would it hold up to a spray bar-plate nitrous system with a 50 to 100 HP shot?
I have a 6-71 supercharged 454 ci engine with dual Holley 750 cfm cabs, RPM heads, etc. Are there NOs systems manufactured for dual carb setups such as this and if so, do you recommend using such a system? If so, which system would you recommend? Thanks.
If you decide to use NOS dont do somethng stupid like most ricers do, Replace your stock pistons and headers, get a highend intercooler (dont be cheap here, perferably one with a emergency liquid Co2 sprayer) and minimize your exhaust backpressure.
Depends on jets... if you're under 50 HP increase, you can get by with the stock parts as long as they're in good shape. Intercooler? You mean for the forced induction engines... ;)
most common case is on forced induction's, though not so bad when used on turbo's pulsed for anti-lag. But in general i personaly would not suggest using this on MOST stock vehicals, primarly those econo in nature. Most stock cast pistons and rings dont like the additional heat and dont respond well to thermal expansion, even more on the aluminium variaity. It can be done safely but theres no real room for error when it comes to regulator CFM.
Yeah, many use it for spool-up to avoid the turbo-lag, even though you should only use it at 3000 RPM and above. You're partly right... Many cars are eco and are set up to handle the stock specs only. Still, a lot of car brands build solid cars that can handle a tune-up... which includes nitrous oxide. BMW M50 engines as an example, can handle alot of tuning. Don't get gready with HP, 'cause one day you want bigger jets and end up blowing up your engine! Oops, that expensive! ;)
@danthemanzizzle You wouldn't want to try and run nitrous continuously.
Nitrous systems are designed to engage ONLY at Wide Open Throttle. If the nitrous is added at any other time, with an average nitrous injection system, you run a high risk of damage to your engine because of a bad mixture of fuel/air at lower RPMs.
There are higher-end systems that ramp up nitrous over an advance curve (progressive system) but they are still designed only for drag racing, not continuous street driving
I built my own Nitrous system back in the mid 70s when information was scarce or just wrong. It was a trial and error using aircraft components. The car was a homebuilt Hillclimb Formula Libre.
On a rolling road dyno I could not get results because the car would just break into wheelspin when the nitrous was triggered. The car propelled me to an Australian National championship win in the 70's. FYI, Nitrous contains a higher % of O2 than air, and its the O2 and extra fuel that gives the power
Ahi, I am not being critical of this video, I am just adding that it is far more complicated than a 45 second video can cover. Its a great little video.
This little clip is only part of a much more in-depth, hour-long video.
If you're familiar with BoxWrench videos, you'll know that we take pride in "over-simplifying" potentially complex engine building subjects and making the content look better than anything offered in the market.
...plus it's just fun to watch... if you're into this kind of stuff that is.
I am into this kind of stuff. I use 10lbs of nitrous a week in my daily driver. The system suffers from wear and tear, causing various intermitent problems that are very hard to diagnose. I spend as much time as I can learning about nitrous systems, if you have a 1 hour video I'd love to see it.
How do I see/get the video?
BTW, my car is a 540 powered 69 Camaro that runs a 250hp shot of NOS on top of the 680HP engine. 930hp total. Check out my videos.
well thats a good build and judging by your motor having 680 hp out of a 540 all motor thats impressive. I wana know your actual #'s on the bottle though, as we both know you cant just add the shot rating and N/A hp to get a total number. Throw that thing on the dyno i wana know what itd do
Zu, i have no plans to put my engine on a dyno. Some things in life should not be measured so you can say what you want without lying. But I will run it down the quarter. Soon.
Hey man, this is only a tiny little video, you should buy the DVD, I have "Basic Engine Building" from these guys and just compelted my first complete rebuild after studying these guys' DVD...and its really good man, you can't judge by this little clip on YouTube, its only for promotion.
Actually no... Nitrous is pretty simple to install. The only complicated part is the electronics. Well, a dry-kit is a bit more complicated because you have to add fuel-pressure from the stock fuelsystem. Not the right amount of fuel, and you'll run lean which means... "boom".
A bit easier with the wet, since you can keep the fuel-pressure at it's stock setting, and just spray fuel directly with the nitrous.
Chrom, I respect your comments and opinion. However, I have been using 10 pounds of nitrous a week for 3 years now in my daily driver. Installing a new kit that still works in your car is easy, but wait until it no longer works and you have to try to fix it!
Easy questions for you: You're at a light, some guy wants to race - how do you know if you have enough or any nitrous left? Why purge? When have you purged enough? When do you purge again?
First of all, I'll weigh the bottle everytime before I go for a drive, so I know if there's enough for whenever I may need it.
Purge to get immediate respons, when activating nitrous. One to two seconds of purging is enough. Purge again after the car has been off for a 12-24 hours.
I dont wanna come off as a rude but i wanna answer the questions....1)You check your pressure guage thats mounted on your guage pod(in a perfect world) 2) you purge because if you have air in the nitrous line the car will bog when you first inject the nitrous 3) i would guess when the purge comes out white?? 4) I guess you purge again after every run...thats what i would do...
excess air doesnt cause them to run hot, so if I have my pump set to maximum and it smokes at full power I could just squirt NOS in and the smoking will stop and I will have extra go, or I could use metanol and nos?

@meangene1000 yes, NOS makes kits that can be installed onto engines that use blowers.
They also have a specific kit for Weiand 6-71 blowers on Big Block Chevy...

@ot2kloon Single Dry Fogger or Single Wet Fogger kit.
Do the reasearch and/or check out the rest of our videos to see why.
This video here is for an engine that has a carburetor...
Watch our 'What is NOS?' clip to learn the difference between the Dry and Wet kits.

i will like to know how to install a nos system to my nissan Se-r 2003, i have some concerns:
*would it harm any interior part of my motor
* would it harm my mass air flow
an if not how do i install it? thanks
sonofabitch1986 1 year ago
have a look at our BoxWrench channel here on youtube and search for the Single Dry Fogger or Single Wet Fogger NOS intro clips.
Either of those are the kits you may want to consider installing.
Both styles of nozzle will install downstream of your MAF so there is no risk of it damaging the sensor.
