Its possible. Not Likely with an 85 shot, but a bigger shot might help you take down the LS1.... But you will need a LOT of mods to keep traction, and a better fuel setup.

i beat a 2000 ss with my nx kit. so i tihnk it's possible, i can remember if i was spray a 75 or a 100 shot...but i did win.

**Boehlke** · 03-24-2003, 09:55 AM

I'd say it's definately possible to take the LS1. I also took a '99 SS spraying a 75 shot. With his setup and the SLP rockers it shouldn't be too difficult, just watch your traction like AZ3.8Camaro said. The 5175 kit should be enough for yah, just use your head when you install it. Don't take any short cuts.

**John_D.** · 03-24-2003, 09:59 AM

Your 200hp compared to a 320hp LS1 is a shortage of about 120hp... The 85 shot will fall short unless you win simply on reaction time or don't spin as much as the other guy. A 120 shot is needed to get the hp levels close to the same.

But... The 85 shot is a whole lot safer than the 120 shot. You need to iron out any issues with an 85, and then, maybe... think about a 120.

I have a 120 with bigger fuel injectors and have a heck of a time with tuning. Fuel delivery may be a problem too, consider a walbro pump or a kenne-bell boost-a-pump.

Another possibility is convert the 85 dry to wet later. Or just start out wet in the first place.

well.. this is some ghetto math right here.. but here it goes.. 200 rwhp +85 ish -> 285 ish..

now.. thats pretty dam close.. that and this guy is a tard.. like he dosent know how to launch for jack yet.. that and i will get to see his dyno later.. he is comming with me when i get the post rocker arm one done..

So.. is the bottem line watch your A/F ratio? becuase then.. in theory.. I install the kit.. i start real low, like 50 shot low.. and then monitor it with auto tap.. and as long as the ratio stays good I shuld be allright?

Here is a good question.. what shuld I be looking for in a/f what is nominal?

thanks so far.. i think i may just need to give this a try..

**malloynx#2** · 03-24-2003, 11:25 AM

i would say go with a wet kit over the dry. you can spraying a 100 shot with the top-notch stock fuel system...also wet kit is going to give more torque, which will be really helpful again the ls1..

**Tiago** · 03-24-2003, 11:51 AM

sorry to say you wont beat that ls1 unless he just plain can't drive.

If you want to bet on driver mistake, then go for it.

You're thinking along the right lines. 285'ish is not competitive with 320 hp though. LT1 maybe, LS1 no.

The kit will come with an 85hp jet to start with (and no other jets). You are probably good with that as a starting point. I would log the a/f ratios and watch it right off the bat and see if it holds where it needs to be.

Autotap will show you o2 sensor voltage, not actual a/f ratio. James (12sec) will say dyno it with a wideband o2 sensor which is more accurate. If you autotap it, shoot for .89-.91 o2 voltages.

Oh boy.

<blockquote>quote:<hr>I have been looking into nitrous for a while now.. and I think the time has come.. and its for ALL the wrong reasons..<hr></blockquote>
Are there right and wrong reasons? You want to go faster, is there any other option? Well, actually, once I considered setting up the fuel solenoid as a flame thrower when it spreayed gas 30' across my yard.

<blockquote>quote:<hr>Basicly.. I gota represent on a buddy with an ls1.. to make a long story short..<hr></blockquote>
With just boltons, they are dynoing over 330RWHP, remember that.

<blockquote>quote:<hr>I am thinking that a dry shot is the best option.. i like the NOS-5175 kit.. its proven and seems like a good base to start..

Now.. lets say.. i get the kit..
Plan A: kidnap james.. make him install it "the right way"..
Plan B: ask a whole bunch of questions..

I dont think james likes plan A...

so here it is..

I dont think I will (ahem) "win" with anything less then an 85 dry shot.. my fiends car is a stock ls1 w/exhaust.. so will an 85 do it?
<hr></blockquote>
Lets say with your mods you are seeing a generous 170RWHP, an 85 shot could net you about 80(based on what james got from his 5175 dry kit at the wheels vs shot size). That still leaves you with well over 50 HP difference, not to mention torque. You also have to look at the powerbands of each car, the LS1 is a topend monster.

<blockquote>quote:<hr>that leads me to question two..
If i set this kit up right.. will it just be ready to go? or exactly what else shuld i do?
<hr></blockquote>
If you have to ask this, you migth as well start saving up to repair your car now. You have an M5, so a window switch will be absolutely necessary. FPSS, WOT switch(included I think), guages, higher octane fuel, etc.

<blockquote>quote:<hr>obviously change the plugs..
but what about pcm tuning, injectors, fuel pump?
<hr></blockquote>
PCM will be fine, injectors will be stressed with a dry shot, you will need your fuel pump to be in top-notch working condition.
<blockquote>quote:<hr>will it just bolt up and work? or am i setting myself up for a huge disaster?
<hr></blockquote>
If you have to ask questions like this, you need to research or you will be in trouble. Oviously, you will learn the most about the mechanics of the system during the install, but you need to learn all the effects and guidlines you need to follow beforehand. Search for terms like "missing a shift" "running lean" "injector lockup" "timing retard" "cold plug" "rpm". Just search!

<blockquote>quote:<hr>I dunno.. part of my says.. bad idea.. but the other says.. i wanna spray..

see mods below.. FYI i am probably putting down about 200 rwhp now (after rocker install)..

Let me know what you all think..

~Billy<hr></blockquote>

Probably? Please......Hit a dyno up, and be ready for a little dissapointment.

**AllTheGoodNamesAreGone** · 03-24-2003, 12:51 PM

Well.. I dont think he will dyno 320 rwhp.. so i think i will be closer then yall think..

Which o2 sensor shuld i scan? i am assuming one of the pre-cat sensors?

I wonder what that nos monkey james thinks

What did it dyno at before the rocker arms? The rockers are proven for 10HP.

James will probably tell you to do a search and hit a wide band dyno for a/f.

There is something wrong with me.. and only NOS will fix it..
