I think either my kit isn't hitting right or a 150 shot just isn't all cracked up to what I thought it'd be. For those who have Stock C5 Z06's... And sprayed a 150 hit, .62N, did you feel a MAJOR difference or no? Because I thought it would hit hard and to be honest, I pulled 6 degrees on the window of spray 3200-6300, I have and I feel it would be faster with just putting the timing BACK in. I'm pretty frustrated and expected more. When it hits should I feel a MAJOR jerk of it or is this all it has to offer?

Thanks,

I've dynoed a lot of LSX Cars with 150shot gained 130-150rwhp 130+rwtq all the time if you didnt feel that something is wrong for sure...

Bottle pressure? Major Jerk are you sure its not running extremely rich? what was A/R ratio on the nitrous?

torkmonstr

what kit are you using wet or dry? either way it should make a big difference. I have the NX kit on 150 setting and I leave my timing factory. The factory has the timing retarded as is, so removing even more just hurts performance.

u should feel a 150 shot.
6 degrees is alot for just 150
what kit do you have and whats the jet sizes.
I would make sure everything is good pull 2-4 degrees and make sure u have good bottle pressure 1000+ and hit it again

What they said.... 2-4 degrees of timing pulled at maximum.

The smallest shot I ever ran on a ls1 was 60, and I still felt that. Make sure both solenoids are working while the car is off.

I am thinking regardless of the timing or the jetting, you should feel something (either bogging or extra power) when you are supposed to be spraying. This makes me think it is the solenoids, wiring, or switches.

What kit are you running

Make sure you have the right F jet for the 62N
it´s probably recomended 35-38 from seller althought it may be too rich like that but it should be save.

and have a right nitrouspressure, 1000-1100psi if you donæt have the right psi or to rich blend you will not get the 150 rwhp as you hoped for.

-6 degree is smart thing to start whith for the 150 shots i would even go -8 degree at first while you are fine tuning the AFR

i ran 35F jet whith a 78N jet @62psi
seller recomended 46N but it was way too rich 10AFR

could also have glogged lines or a bad solinoid

good luck

You'll feel it once you get it working properly.

It's a HSW wet kit. I was running a 34F for the 62N, but switched over to a 31F. Also running an FJO Progressive controller. I tested the solenoids and they work just fine and spray good. But apparently the controller is giving me issues. It turns green when I'm in the set window switch and WOT but it doesn't hit >_>. Also on BR7's. But I'm gonna probably reset it to 4 degrees pulled, since torkmonstr has a great point.

Thank you so much for the responses! I'll let you guys know if I get it worked out!

Hope you get it worked out. It's quite the kick when it hits.

Pulling 6 degrees of timing and running the BR7's is the proper setup for a 150 shot. The timing setting (-6 degrees) and the plugs are not causing you a performance issue,but they will help you maintain a reasonable safety cushion once you work out the nitrous activation problem.

You never did state what your bottle pressure was when the system was supposedly activated...low bottle pressure makes for a poor nitrous hit. I run between 950/1000 psi when on the juice.

Milan

Switch to E85 and forget pulling timing...then you will feel it for sure.

molten vett

Once its working right he'll feel it for sure anyway. When nitrous hits it doesn't have to build up its 150hp right now!
Also check the settings on your fjo and make sure no gears are locked out.

Let us know how this is wired so we can help you.

Did you use the rising or falling TPS wire when you wired it?

FuglyHippo

Figured it out! Used the wrong RPM wire for the controller. And I'm liking the 150 shot! It comes in hard! And sorry for not answering you before, but I was running it at 950 psi. I plan on pulling only 4 degrees instead of the 6 degrees. I'll be reading plugs on Sunday.

What do you guys think about running a 31F with the 62N jet? I think I'm gonna throw either a 33 or 32 in there. But I know the reccomended jetting is always too fat.

Thanks for the responses!

With nitrous, too much fuel can hurt your motor just as quickly as not enough.

Glad you finally felt it.

98vettedave

Getting the system to activate always makes a big difference in performance. Running more timing with nitrous doesn't necessarily mean you'll produce more power. Ive tried -4* vs -6* of timing and it didn't make a squat of difference at the strip. The -6* did make the setup a little safer though...it's your call...have fun.

As previously stated by another...running rich on nitrous can also be detrimental to the engine. Having a good tune prior to running the 1320' is always a good idea!

FuglyHippo

Thanks guys! Nitrous is becoming extremely simple for me now! It had me pretty scared before, but now I'm pretty comfortable. Taking the car to the track Sunday to read plugs.

Thanks again!

Glad you got it worked out. But dont get to comfortable with it are you may get a blown motor...

HvyHitr

Get a bottle heater, the pressure is a bit low. If you plan on tracking the car get a purge on there too. Nitrous burps off the line can be ugly. I used to run a c4 with a two stage on it and it was a blast, 100/150. Just be safe with it.

FuglyHippo

If I blow the motor, I'll just get a forged shortblock. I'm not sweating it.

Thanks for the help guys!
