I find my car uncomfortably fast with the 75 shot. If I could take a guess I could run high 10's with this if I could hook.

The last time I had that kind of speed rush was when I did 165 on my built motorcycle. Dyno in less than a week!

If you have suspension and chassis rigidity issues okay. But I doubt that's the problem and it's probably you're not use to it as of yet. Give it some time and you'll be reaching for the 100 HP jets or more soon enough. Good luck with it.

I have a pretty good suspension set up. I am just not used to it. Just not quite a 850 hp badass yet ha.

This is my current tune. But it was for 93 octane and a massive sea level difference. Plus it's ridiculously fat, so fat that I fouled plugs and car wouldn't even turn over.

I only have 91 available.

I am going to send it to Vortech on Monday. I was able to pull 465 RWHP and 395 TQ from a boosted only tune. Supercharger impeller began to get too much play and my charger started to sound like a can full of marbles.

Nitrous dyno should be within 2 weeks.

Also, I am wondering if it would be plausible and safe to run a 100 shot? Thoughts?

Nice! Still excited to see your results. I am a little lazy to go back and read from the beginning, but you are running a wet shot correct? If you have enough fuel for your setup prior to nitrous shot, you SHOULD be okay to run the 100 as long as you have supporting mods to with hold the power. Plummer will hopefully chime in with his experience with running nitrous + boost

I am running a 255 LPH in tank and a 166 LPH in line pump with 42 # injectors. Yes, it's a wet shot.

This is what I have to start, any other items anyone would recommend? I plan on running a 50 or 75 shot.

I have 1996 Cobra 4V with a Vortech blower. I am new to n20.
I am running this window switch :

Its quite a bit cheaper and it gets the job done. wiring it up is super easy. I have not had a problem with this window switch any time I have been spraying

yea after I posted that I realized it was kind of an old post. How you like your set up?

I can't seem to feel the 75 shot. Going to try a dyno pull and see if it needs to be adjusted.

make sure your bottle pressure is adequate. You should really be able to feel a 75 shot on a pretty high boosted car

I figured out why the nitrous felt weak...

Turns out for whatever reason the Zex NMU didn't seem to like the voltage reading at wide open throttle, I was only getting a half shot randomly. So I changed the settings on the NMU (nitrous management unit) to shoot nitrous at 3/4 throttle. And BAM, that 100 shot feels monstrous now!

Pretty excited. I am putting the smaller pulley and methanol on tomorrow. Then FINALLY I promise I will have the dyno numbers.
