View Full Version : Nitrous System
I am considering having a RM Racing NOS installed. Has anyone had one installed and your opinion on it.
I have the 70 HP shot. It's a fun toy and gives you the same power as the common turbo/super charger setups... But it's not "always there" like those setups. You have to open the main tank valve if you plan to use it, then turn it on and hit the button to activate it, and the tank is empty in a couple dozen shots (more or less depending how long you use it each time). Of course it's also a lot cheaper than either the turbo or supercharger. And if you're not using it you don't even know you have it.
Does NOS effect engine life?
A small shot like 70 HP on an NSX isn't going to hurt anything as long as your engine is in good shape to start with.
how fast can a 70 shot nos NSX go?
Just curious, where do you fill your tank up, how long does it last, and how much is each fill?
It knocks about a second off your 1/4 mile.
How long a tank lasts depends how you use it. A typical 10lb tank will do around two dozen 1/4 mile runs and refills typically cost $25 give or take. Most major speed shops can do refills.
LUD,
Could you post (or private me) the details on your NOS setup and where I may pick one up..

The only part about Nitrous that really scares me is the Solenoids going bad. There have been incidents when the fuel solenoid went bad, so no extra fuel was being provided to the engine, while still spraying the Nitrous.
Lud, do you have wet or dry setup?

i love mine cars never been beat yet but i'm sure it will one day
i had my dry kit on my 96' nsx for 2 years and never had any problems with engine wear and i now i have it on my other nsx for about 1 years and still having fun.
it's sweet to beat an 12 second car and see the look on there face :-)

Wow, talk about an old thread. I had the RM 70 HP dry kit, but I have long since sold that NSX and bought a different one!

Wow someone must have used the search feature without reading the date. At least they searched http://www.nsxprime.com/ubb/biggrin.gif
Even Brad has since sold his nitrous kit.

yes, it now resides on my car.with lots of mods to the kit setup.
and I am manufacturing the original design with all the same parts and it will be a exact clone if wanted by the buyer.but will have other options available.this is happening.but am reluctent to post to much on it until it is READY to ship.and I believe the price will turn some heads.the kit that ships will be no beta kit.it will be the tried and true rm design that has a proven track record of safety.which is hard to say about most dry kits. it will be targeted to those that cannot afford a s/c turbo but want reliable and safe nitrous.therefore the kit will retain the orginal 70 shot. an upgrade kit will be available (larger shot) but must include extra safety features and recommendations for fuel system enhancements

Hey 5inchfatlip is running 150 shot direct port. I have to tell you...nothing and I mean nothing comes close to it. None of the turbos or twin turbos, or supercharged ones come close.

Hey Tuan! Welcome to the forum. I'll be purchasing an NSX soon, and this is a great online community for NSX enthusiasts. Oh, and don't worry, I'll be hanging on to the C5 as well http://www.nsxprime.com/ubb/biggrin.gif

150 Shot Direct Port http://www.nsxprime.com/ubb/eek.gif Wow...you are a brave man to run that kind of shot on an NSX. Do you have a built motor? Details http://www.nsxprime.com/ubb/smile.gif

I would be willing to check the accuracy of that statement with my single turbo, coming up north anytime soon?

Hey Gerry-
I'm not coming up north anytime, you coming down south?? =)
I've seen and read alot about your setup and would love a ride sometime. I've also seen some videos but its real hard to compare, and seen your dyno sheets as well, very impressive.
Me and Hopeful have ridden in just about every setup out there, SC, Turbos, and they done "feel" as fast but maybe they are, but I havent really felt anything like it.
I also dont know exactly how your turbo "kicks" in, if its linear or right at full throttle, when mine kicks its all of a sudden making it pretty crazy.

I just might take a special trip down south to one of the meetings at NSX Modified, would you be able to make one if given notice?
if this event takes place i hope there will be video coverage as well as statements from both parties as i am not the only one interested.

Hell, I'd make a trip down to HB just to see this. =) As far as I knew, 100 shot was just about the safe limit for a stock block. 150 is asking for trouble unless some extra work has been done. Gerry should bring the slicks. I wanna see Leo's car hit it, haven't had a chance to see it run yet.

Gerry- that would be great if you were able to come down, just let me know a couple weeks in advance if the opportunity pops up..
There arent many places in Huntington Beach where we can make a good run, too many cops also, we would have to go to another place...it would kinda be obvious if we had all kinds of NSX's following us =)
If you dont mind, private me an email, I'd like to talk to you about your setup and internals...thanks..

Slicks? the car runs mid 11's with street tires @ 126mph babying the launch.

Woo hoo!!! I want a ride in Gerry's car. That car is very very nice. As for 5inchfatlip's car, it's all taken care of, top and I believe bottom as well. My understanding is it also is a high-11 second car smoking tires in both 1st and 2nd. Now if only we could get some good launches from both cars. Then I guess we would quit hearing the "NSX vs (whatever car you want to put in here)" debate.
Wow this would be a very nice battle to watch http://www.nsxprime.com/ubb/smile.gif I remember seeing Gerry do a 11.9 a year ago Sacramento Raceway. It was a pretty sweet lookin ride.

Lets make it a shootout and meet in the middle!
My NSX also has NOS as a power adder, but this car hasn’t been to the strip yet.
Have you ever dyno'ed with the turbo?
Sounds like a fast setup.
I would like to point out to everyone reading, that an engine is only as strong as it’s weakest link. If it’s going to break at a specific HP, it doesn’t matter which power adder is used to get to that HP level. One might derive the maximum HP by viewing this news group for the maximum HP with any power adder, like the new Bosch SC.
I would also like to point out that the peak HP isn’t the only key to good ET’s, (besides traction, and shifting). If a turbo NSX is making 450 hp, but ramps from 100 hp at 3000 rpm.
Vs. a NOS NSX that only makes 400 hp (or even 450), but ramps from 250 hp at 3000 rpm, The NOS has the advantage, with the higher average HP.
Also believe it or not… (If you have the right suspension/hook) the higher low-end torque/hp will keep the tires loaded better for faster 0 to 60 ft times.

I had a 150 shot, and with BFGoodrich drag radials ran a 10.90 at 126. I have driven Gerry's car and it felt faster than mine did. IMO I think his car would run mid 10's with slicks. I hope it is taped so I can see the results.

10.90’s… Damn! What size slick? Suspension? Other mods?
My intention was to put slicks on my stock rims, Adjustable shocks, disconnect the sway bars, and weight if needed.
10.90’s… Damn, I get near 25 miles to the gallon, and drive it every day.

255 50 16 BF Goodrich Drag radials with the rear sway bar disconnected. Have you done any internal engine mods? If not running a 150 shot is kind of in the gray area. I would be careful. I had an adjustable fuel pressure regulator to boost the fuel pressure to 50 at idle and 75 in VTEC. I kicked in the NOS at about 4500 in 1st gear and left it on until the end of the quarter mile. They threw me off the track after only one run because I don't have a roll cage. I am going to be running a Twin turbo with a 100 shot of NOS, maybe even back to a 150. I am going to see how much hp the car can handle. I am getting all the internal engine mods done right now. Hope to have it back soon. Will let you know how it feels running 12 lbs of boost with the NOS also. Do you have a direct port?

Damn, 150 shot on stock internals? What type of setup do you have, and who did the install. 10.9, Very impressive!

It was on stock internals, thus is why it is at Gerry's shop getting rebuilt. 150 on stock internals was too much. I had a local shop called Westminster Speed do the install. I got the bottle warmer, remote opener, full throttle switch and fuel pressure cut off switch. If you go that high you need to have all the safety features. I would not recommend anything over 125 on stock internals. Badcarma is very knowledgable on NOS. If you have any questions I would ask him. I raised the fuel pressure so I could hit the nitrous at lower RPM's. I felt comfortable using it as low as 3000RPM's.

The higher pressure for lower RPM is good information; I have been trouble shooting that problem for a while. I assumed my problem was timing related. Andrew at Real Time Racing told me that the only weak links in your stock engine, are the pistons and most important the main caps. The pistons I’m sure your already changing, for the turbo, But the main caps he had to make him self.
