ive got a 2000 with the ms4 cam ported 243heads. fast 92mm , ls2 tb, long tubes ,fast 36lb flow matched injectors, prc dual valve springs,no cats, bassani X pipe,vera ram, 01+ 5pim maf, and for all intensive purposes its a rocket ship, but it does have 80k on it and i will be putting in a stroked ls2 in the future. so im back and forth on the idea of having just a little more at the flip of a switch. my main thing is do i even have the option with my setup or would i just end up slinging it all apart?

 

Performance mods do add stress to internal components. Adding a little shot could last for a long time if tuned properly, but it could also force you into your 402 a little earlier which might not be such a bad thing.

 

Your running a setup identical to mine. cam and all. It is indeed pretty fast.

I just added a 100 wet shot the other day. It definately made a good difference and I dont even have my bottle heater, bottle pressure was way low.

I plan to get a tune and up the shot higher. I mainly did 100 to test the system and have it installed. I did it on stock TR5 plugs, pulled over checked the plugs, and they were perfect. I since added TR6(1 step colder) to be on the safe side.

The Safe limit ends at 600rwhp no matter what way you slice it, boost, spray with these bottom ends Ive been on the nitrous forum at ls1tech. Theres some guys that are running heads and cam and a 200 shot at arround 750hp is the record for the stock bottom end.

they are renegades though and not scared of what could happen.


My personal plan is a 150-175shot(race day only) With proper tuning-timing to do the 175, and I dont plan on doing it allot to keep longativity.

Theres a guy named mark murillo that has a black c5 z06, Heads cam 175 shot on stock bottom end running 9's So the potential is there if you chose to stop modding with after you add spray.

If 100shot fits your fancy, Its pretty safe and should last you a long time, and you should be able to squeeze it out of your stock fuel system, though id add a fuel pressure safety switch just incase.

My personal setup will have a 255lph fuel pump, Racetronix hotwire harness,Bigger inecjors (not an necessity with a wet kit but im getting some anyhow)a Fjo progressive controller, and a good bottle warmer and tune

 

I would verify your fuel system is up to snuff. If it makes you feel more comfortable, I personally have installed nitrous kits on higher mileage motors than yours with great success. We generally do a leak down on the higher mileage cars to verify the condition of the rings. Let me know if you have any questions. Thanks.

Lots of guys spray high mileage motors.. like over 100k mi. motors.
Stick with a 100 shot.
Go wet if you don't want to mess with your injectors. (although dry is safer IMO)
tune (or wideband monitoring) is pretty essential.

If anything did go wrong, it would have gone wrong anyway.. just a little later than it did.

 

I'll admit Im not expert on the matter ( and frankly a "noob" on these forums ), but ive been around at least 5 good buddies cars all on spray. 3 or 4 had them professionally installed, and when they asked the experts their, all of them said to not go beyond a 125 shot. Disregarding possible danger, unless your vette can hold up to that much more power at the flywheel, i would suggest an adjustible 75-125 wet shot.

This is a kit recommended for an LS1 (u got an ls1?)

About the other buddy that installed a 200 shot on his '98 Z28 (had exhaust,heads,intake,lowered). It was fun hitting mid-11s on the quarter, but those engines arnt meant to take that and hes had to replace his clutch, flywheel and un-install his kit he had spent a good installing

and trust me...125 shot makes a BIG difference...i like to think of it as a second engine

 

I would not be afraid to spray this car what so ever. Vettekidc5 gave the best advice, the ceiling for the stock bottom is about 600/650 and that is with a spot on tune and a good fuel system.

I have sprayed the crap out of my 100% stock LS6, over 300 1/4 mile passes, at upto 250rwhp shot. I finally bent a rod and broke a ring land with a 285rwhp shot on the dyno, but still won the dyno trophy for sprayed cars, lol. Multi staging is the answer.

Here's a link from the C6 section, though applies equally to the C5. I think you can garner much insight from this thread. The key to a nice size shot is to break up the torque a little bit. The sprayed high HP motors that actually live a long life are for the most part multi staged to control the torque on the botton end at lower rpms. Let me know if I can help in any way.

Must agree with Robert56@RNS I have 58,000 miles on my 2001 Coupe. Many of them 1/4 mile at a time.
I currently have a 150 wet shot using the NOS plate. I have only run a few dozen passes with the nitrous but I notice nothing out of the ordinary with the motor. Runs great and feels great.
This is being done with the STOCK fuel system.

 

your established LSx tuner said what?...................

 

Robert,

I pm'd you a couple weeks ago to get some help with a nitrous setup/some advice and was wondering if you could shoot me one back...the Z is begging for a bottle

 

I am so sorry, I have as of yet not figured out a good way to stay on top of my pms/e-mails. Right now looking at my in box there are 89 of them. I will see if I can find yours and reply promptly. Once again, very sorry as my Vette buddies form this forum are my priority.
Robert

 

I have a 100 shot on my wife's C5 and there's no issues even with 112K on the clock.

 

yeah man the LS1 eats that nos up like no other

 

I have a twin bottle dual stage system I just pulled off my car with a 2 stage window switch. If your interested PM me

 

nice!!!
