Sup guys,

Anyone know how the stock clutch holds up to say a 75-100 shot of nitrous??? I know my clutch in the civic needed to be replaced before I finished the first bottle. Some cars do better than others with bigger mods. Anyone had good luck with the stock clutch when sprayin???

Thanks.

 

From what ive gathered a Z with JUST 1 step colder plugs can handle a 125 wet shot with no problems. Clutch shouldnt be an issue.

 

I don't know how much the stock clutch is good for but I can tell you that I wouldn't count on it for long. I think the torque may be a little too much for the stock clutch. May work for a short time, but I doubt very long at all. In addition, if you are not progressive spraying, you will introduce the load on the drivetrain in a very sudden manner which will cause even more issues with the stock clutch.

The stock clutch will hold it, but the question is, for how long? I personally upgraded to the JWT clutch and flywheel as a safeguard after putting my Z on a dyno and seeing how much a 75 shot really did. Now I spray anywhere between 50 and 150 with nothing more than a laptop adjustment

 

i have had no problems yet, stock clutch and a 125 shot, its actually a 130 shot to the wheels according to the guy at NX. i have launched on the track once so far with slicks and nitrous. i spun a lot so i will let you know in a week or two how it holds up when i get to go back to the track more, as far as the street goes though. no problems as of yet....

 

That is some good info. Also, what step colder are you running on the 125 shot? I have gone as far as 1 step for a 100 shot, but am a little nervous with 1 step and anything higher. Spray a 125 on the 1 steps once and it was sick! Pick up a little noise on the knock sensor with my SAFC II but nothing high.

 

Jeremy, do you notice a little sliding of the clutch when you hit 3rd or 4th on the spray?

 

Good to hear. Did you retard timing on the Z? I used 1 step colder NGKs and retarded the timing 2 degrees on the civic. The compression on the Z is significantly higher than my civic which makes me wonder if they retard the timing a little more. 10.3:1 VS 9.2:1

 

How do you guys hook up the laptop to the car's ecu? Just curious. And what software would you use? I'm good with computers but intermediate as far as mechanical skills with cars. Still learning though.

 

Actually there is a totally seperate control unit that taps into the OEM ECU and nitrous system. That control unit is called the Nitrous Express Maximizer. It pulls tach, trottle position, and 02 sensor (you can use narrow or wideband systems) from the OEM ECU.

The Maximizer pulses the nitrous and fuel selinoids at a frequency which is based on the brand of selinoids used. This pulsating is what controls the amount of nitrous and fuel that passes throught the seliniods, followed by the jets, then into the motor.

Let's say that you have the 100 shot jets installed in the fogger and you had a Maximizer. You can tell it to only spray any percentage from 0 to 100% of what that jet size is. So if you set it at 50%, you would spray roughly a 50 shot. Or if you had the 150 jets in, 50% would be roughly a 75 shot. I was apprehensive about this systems ability to effectively control the shot, but my concerns were put to rest when I applied changes on the dyno.

There are a ton of automated safety features built into it as well. Do some research. If you are going nitrous, this setup is the safest and best way to go. Not to mention the fact that it is great to be able to change shots on the fly without having to stop to change out jets.

I have had no problems with the stock clutch while spraying. I'm using 1 step colder plugs with a 100 shot.

mayhem: What are the jet sizes you are using?

 

sorry havent replied in a while....

andrew no slipping at all on the clutch in any gear...

true i am using a 53 N20 and a 28 fuel...

12 many just one step colder.... 6

old school you cant retard the timing on the Z unless you hook it up to the consult II which can only do it -2 degrees across the board, or get a piggyback computer (utec, EMU)

 

I have been running N2O with high boost for awhile with no issues.. Of course now I have an APS ST and I am getting a built engine but that's part of the disease.

 

I'm running stock clutch w/ 100shot NOS. The clutch started slipping last week and a new one is on order.

 

Just out of curiousity, how many miles on that clutch and how many miles since the nitrous install?

 

To be honest I dont use NOS often, only used it 4 times since I installed it. My car has a total of 11K miles, last 2k miles w/ NOS.

The thing is that huge tourqe when using NOS and flooring the car kills the clutch faster.

 

what about on a titlon clutch and flywheel...how do u think that will hold up??

 

i would hope so, or i would get my money back and get an ACT...

 

Ive got the tilton combo too and plan on going with a 125 wet shot. Assuming that everything is installed correctly and is working fine the torque specs on the tilton clutch should be able to hold it.

 

Pretty good read. I think Im going N2O. Seems that is cheaper than Turbo or SC which leaves extra money for the proper upgraded needed so the car can handel the N2O with minimal problems. I had N2O on my old Cavalier Convertible. Ran a 14.0 at 101 in the quarter on a 100 shot with just colder plugs, injectors and stage 3 clutch. What times are you guys running with a 75-100 shot?

 

bepends on your Z, but 12s at over 110 mph should be no problem on a more or less stock car.
