So right now my car has the very radical MS4 cam. I have talked to EPS about a much more fuel efficient cam with good spring longevity and Geoff specced out a 222/230 114 +2 LSA cam. I am loosely considering nitrous in the future and I was wondering how this cam would perform on the spray? It wont influence the specs I ask for but I figured it would be nice to know anyway.


Provided I were to get a kit I would be utterly paranoid to use it and definitely wouldn't spray anything larger than a 100 shot- probably even smaller because I simply wouldn't have the funds to replace my engine should something go wrong. What I do have the funds for and am potentially willing to spend for is to do a kit right with ALL of the safety features. But since I am also completely new to nitrous, I would want one that had the least chance for something to go wrong and/or the least day to day maintenance. So is my choice wet or dry? With a dry kit, how often do I need to check my MAF? With wet, how can I completely minimize the possibility of a nitrous backfire? I would gladly go direct port but I've heard it is a waste for the small amount I would be spraying. Is this true? Could I use my stock Ls6 intake?

Finally, is there anyone who has routinely sprayed their same set up for 30-50k miles? Yes nitrous does get a bad rap for people not having it set up properly but every time I try to find a thread of someone who has consistently sprayed their setup over the life of the car, I just get threads about nitrous use on a high mileage car which is not the same thing. I'd love consistent proof that there are people out there spraying away for tens of thousands of miles with absolutely no issue.

 

That cam will be just fine with nitrous. A single nozzle wet kit with the right plugs, enough fuel, and some timing pulled and you're good to go.

The cam that EPS spec'd would be great for nitrous. With a dry nitrous system, you're going to have to compensate by adding fuel through the injectors. Depending on the mods you already have done to the car, your injectors may not be able to keep up with much. Also, you'd have to switch between tunes for nitrous and N/A driving which can sometimes become a hassle. Personally, I'd recommend the following:

Nitrous Outlet wet plate system w/10lb bottle
Purge
Heated bracket
Bottle gauge
NOS Mini progressive controller
Lingenfelter LNC2000
Fuel pressure safety switch
NGK BR7EF plugs

 

What about a window switch? I neglected to state the car is an M6. It also has 36 lbs injectors so I imagine that's enough fuel.

How about how to avoid a nitrous backfire? Are they very rare? Are there some kits more prone to it than others? Ill post the rest of the cars specs in a bit.

Edit- parts are as follows:

TSP Magic Stick 4 Cam 239/242 .649"/609" 111 LSA
GM LS6 Race Heads- 61.9cc, 250cc Intake, 85cc exhaust
Yella Terra Rockers 1.7:1 Ratio
PRC Dual Valve Springs w/Titanium Retainers. Previous owner says the springs only have 300 miles on them.
Thunder Racing Hardened Pushrods 7.4"
GM CTS-V Race lifters (GM 88958689)
ARP Rod and Main bolts
Powerband Underdrive Pulley
BBK 80mm Throttle Body
36# injectors
Ported MAF
Jet Hot 1 7/8" Longtube Headers
4.10s

 

Definitely would pick up a window switch. Especially with an M6. 190$ well spent that could potentially save your motor.

Definitely go with a window switch. Typically a backfire will occur because the car is lean, over timed or sprayed at too low of an rpm.That setup will EAT on a 200 shot! Just make sure you have enough fuel supply!

 

i'll jump in. about to put a proton kit on my m6 ls1 gto.
i have ms3 cam
ai 241 / 219cc heads
42lb green tops
92 / 92 intake combo with fuel rails
twin disc clutch

was thinking about changing up the cam, but if the powers that
be think the ms3 cam would work well in the upper rpm ranges
with spray, i may keep it in there.

 

The MS3 cam does very well with nitrous. Just do a search and you'll see

 

i've searched around a bit on ls1gto, and wasn't much info, but looks like on here a few folks have done it with good results. should be fun

 

Just for reference back when I was running my LS6 intake and a 100 shot I gained approximately 108 rwhp with a cam almost identical to the MS3

 

sweet. im at 440 wheel, so a 100 shot should put me right over 500 wheel.

 

Yes probably more like 540

 

ill need to start saving for my solid axle swap @ 540 lol

 

Actually my buddy makes 600 rwhp on his 06 Goat with the stock IRS, and is doing just fine, but he doesn't track the car much

 

right - track digs will kill the rear end on these things. i plan on doing
a sra swap in it one of these days anyway, so i'm not worried about
breaking anything.

 

How much am I looking at for a properly installed wet kit with all of the safety features? I doubt I would ever trust myself to do the install myself.

 

If you're talking a brand new kit will all the basic bells and whistles then you're probably going to be in the $1200 range give or take a few. Install might be around $500 or so I'm guessing

 

That is a pretty good estimate. Also depends on how far you go with accessories if you go with an entry level system or all out.

Thanks,
Garrett

 

Doesn't the NOS mini have a built in window switch?
