Default SRT + Nitrous.

Seeking Nitrous Guru help here. I don't own an SRT anymore, however I do run nitrous on my Vette.

However, I am only mildly informed about all aspects of nitrous, and had a few N20 related questions.

First off, concerning SRTs, what is approximately the highest shot you could run on a Stock motor SRT, also a built motor SRT. With this added power what comes with it?

Would you need an independent fuel system? Permanent Race Gas? Boost relation?

I have plenty of questions, but I may save those for later. Thanks in advance.

I believe the highest shot to run on a stock srt before problems start to arise is 100 shot, but on a modified motor I've seen more than 180 shot being used on a srt. As far as fuel system with most base nitrous kits, on a stock srt its easy to dyno tune it using the fuel jet that comes with the kit to make sure everything is fine, but for the most part nitrous supplies its own fuel so it's cool. When you start to run a bigger nitrous jet then you start looking into a return line or possibly injectors, but the mane thing "from what I understand" is that you should tune your srt first before adding the nitrous, but just make sure its a safe tune to where you have some room for play. For the most part nitrous bumps up your boost usually by 2-4lbs, but this is from what I've researched when I was going to run the juice

^^^pretty much word for word that i wanted to say...i mean if you have a motor like the DCR solid block motor..they are spraying a 400 shot. lol thats also a 7sec srt-4...but yea 100 is as high as i've heard...i mean im sure you could do some 125's for a lil while with a soid fuel pump and the voltage mod. as long as you have the properly sized jets..should be ok. i've heard of stock srt's with few bolt-ons running like 18psi ( before spray ) making like 475hp and a lil over 500 ft-lbs. on a 100 shot which is STUPID AWESOME!! LOL so yea..

N2MB made some posts about his stock turbo nitrous setup, it was pretty impressive from what I read.

stock motor non direct port 75-100 has been done rather successfully.

if the motor is built it would really be a question of "how" built and built for "what". big turbo+nitrous, stocker+nitrous etc...

and fuel is really a matter of choice. jay ran a 100 shot stock as stock fuel gets and made over 400/400 wheel. personally I run 255/rewire and made a return line for my set-up.

I keep hearing of the nitrous causing something to melt in the SRT-4 engine bay. Any truth to this?

On a built Motor Neon Marine sprayed a 200whp shot. that was direct port. He sold the car before he got it all sorted out. I don't think the car ever got to the track on the DP set up.

On a stock motor with a single fogger I personally would not run more than 75whp, but that's because I don't have the tuning knowledge and as you all know the more power you are making, leaves a smaller margin for error. Who knows, now that my car is not a DD, perhaps I'll jet a 100, put in some race gas and see what happens. hopefully N2MB will chime in and tell us what he did when he sprayed 100.

I've read anything more than a 100 hp shot with a single fogger you run into distribution problems i can't say for sure... i'm also sure someone has run more than that....Way back in the day before i went direct port fogger on the stang i used to run a 175 shot using the exact same NX fogger i'm using on the srt... but 75 hp is as far as i'm going on this car.

Ddog did a bit of impromptu testing on or IM's with a cigar. when I get home I'll search for the post and put up the link. It is also my understanding that the updraft IM cyl 1 gets more nitrous than 4. as you up it, you are adding even more to cyl 1. I don't know that as fact, just what I've read.

He never got the kit jetter for 200 but did spray a 150 that wasnt hitting very hard due to leeks in the nitrous system. I helped with the car and know the guy, the worst part is he sold it as is an got a mustang.

I dont blame him... I hate my neon. It was a daily driver that I bought and started modifying, I sold my Camaro shortly after... My next purchase is a terminator.

terminators can be made fast but they do have their flaws, the engine is not one nor the 20+yr old chassis it rides on thats proven itself over the years but the rear suspension/some drivetrain components will keep your wallet pretty busy
