I'm about to install a wet kit on my car but was wondering about the fuel. I h ave the perrin hiflow fuel rail, walboro 255lph fuel pump, pte 680cc injectors and tuning with TUrboxs Utec how much of a shot would I be able to spray.. I have never dealt with n2o before looking for input... My other supporting mods is 3 in tbe, intake, HKS EVC V boostcontroller, comp cams 280/280

 

no one knows??

 

well .. as far as i know .. from a few guys on here .. a 50 shot would be on the safe side and of course it would be nice to either put it on the dyno or a wideband to see what your AFR is ..

and i think N20 is kinda taboo on here .. alot of guys run it .. but no one talks about it LOL

 

My plan was to have a map set for nitrous along with pump and race gas maps..

 

I spray 100 shot on mine and I love it. Best mod yet. You should be fine with your mods. Since you are putting on a wet kit you do not have to worry about fuel since it adds it. The only thing I would worry about is your timing maps.

 

as long as you get your tune to run safe ... i think 50 shot would be nice

 

appreciate the replies. I wanted to do 75 shot is that too much??

 

this really bothers me, because i'm having trouble finding info on it. I've seen people run it... its cheap, easy, helps spool the turbo, and cools the intake charge. So why doesnt anyone talk about it.

 

You should be fine as long as you are going to have it tuned for nitrous. But the problem is everyone is scared to tune nitrous on anything. It can be a safe mod when used in moderation and you have a big enough fuel pump to support it.

 

LOL .. its just like banging a fat chick .. they do the same and something offers more than regulars .. but no one ever talks about it LOL

but on a serious note .. i've done research on it as well and found nothing, so the best bet is to talk to tuners if you're not tuning it yourself ......

 

I was going to have a direct port system installed with a 100 shot on the meth/93 map and a bigger shot on a C-16 map. You do need a seperate map for each setting. I talked to Martin at AMS about it.

I'm going to wait and see how it runs without nitrous first.

This was on a built motor so if I were you I would call a good shop like AMS or Buschur and I'm sure they will give you HONEST answers to your questions. Their not going to sell you something that will hurt your engine.

Good luck

 

I am a long time user of juice. There are a ton of variables that you don't learn about until you actually run the squeeze for a bit. I will list a few:

1. Its too easy to add a bigger jet. You may slap on a 50 shot and your car will love it. It may run perfect. Then you slap on a 75 shot and man oh man the car just rips and everything is in tune. Eventually you will build a false sense of security and try to add that 100 shot. This may actually work a few times but have one hickup with anything spark, fuel, knock, and WHAM!
2. The bottle is not instantly up to operating pressure. Even on 70 degree days a full bottle will need to be heated using a heater. That being said on 90 degree days the bottle may be over pressurized and you'll have to wait for it to cool down before spraying. When I say use the heater sometimes it takes 30-45 minutes to get a half full bottle up too 950PSI. In summary unless you open the bottle everytime you leave the house (and heat it) you wont be prepared for a drag race. You cannot just open the bottle on 1st ave and be ready to lay waste at 2nd ave.
3. Unless you own your own filling station and purchase a mother bottle from a gas/chem company you will probably get raped on the price you pay for nitrous. Around here I get charged $4.50/LB and a $5 hookup fee. I dropped the cash on purchased my own filling station. This dropped the price down to about $2.90/LB. Depending upon your location your prices may vary.
4. It's too easy to add a bigger shot
5. There is additional added fear that a part may fail and the motor may say goodbye. If your fuel solinoid takes a crap during a pass bad things could happen. Sure there are many safety items you can buy to prevent some issues but it is likely sooner or later something not soo good will happen. Bad things have happened to me. I actually melted a valve when I picked up a tank of bad gas. Apparently in some states they have enthanol "enhanced" fuel. This fuel was a poor choice to run with juice. I definately would recommend running race gas with laughing gas. I also had a nitrous backfire. I believe my bottle pressure wasn't quite where it needed to be (might have been cold) and when I went to spray I blew then entire intake side off the motor. The explosion was so massive it bent my throttle body blade. Motor was fine but I shat myself when it happend. I've also missed a shift and went WOT while on the juice since there was no load on the motor I didn't notice any fallout but if I had actually done a 1-2-3-2 shift and dumped the clutch there would have been pieces and parts everywhere.
6. It's too easy to add a bigger shot
7. You have to prep your car for juice. On a turbo car you WILL need to pull timing and if you are running bleeding edge boost you'll have to back it down because nitrous will cause it to creep. Prepping your car also means running the correct spark plugs and odds are your clutch will not appreciate it at all. If you are serious about keeping your motor healthy you'll have to check your plugs after each session of spraying. Reading plus is about the best way to determine how the motor is responding. In the end its very cheap power IF you run a big shot, but with all the cons that come with it it may just be BETTER to upgrade something else, get a little less power, but have it all the time.

 

I have an upgraded clutch ACT 2900

 

Which is just about the weakest clutch upgrade available.

 

your gonna need more than an upgraded clutch if you plan on running a 100 shot of nitrous. the only way i would use nitrous on an evo would be if i was using a big turbo that spooled up late,and then i would just use a 35-50 shot just to spool up faster. there are too many cons with NO2 too justify the use of it in my opinion. you can take the money and put it to better use without the worries associated with the use of NO2,good luck
