100 shot of love juice
 

i'm thinking of bumping up the shot with the aid of the smt-6.

i've read that you can add and run a 5th fuel injector with the smt-6. so my question is where would the 5th injector run into? also should you still run the kit wet at that point or switch over to a dry system?

why would you need a 5th injector with a wet kit? just switch the fuel jets to what is required

Whoa never go from a wet to a dry when going bigger. Just change out the fuel solenoids. Wet kits are really only thing they should've made unless you have the ability to adjust your fuel.

you might need a better fuel pump if anything and a few dyno runs to get good more accurate jet sizes. also you might want to start out at 75 and a do a progression to see the results as you continue to add more n20 and fuel. if you go to zex.com and look at the jet chart it shows how to configure for and increase of 10hp evrytime. i belive it 2 fuel and 4 n2o every 10hp.

I ran 100 shot for 6 months on my 2.2 didnt have a problem only thing i did was that my gas jet was for a 110 shot just to run a little safer

you could probably get away with it, might want to run a progressive controller though so it didn't hit so hard at one point...that is whats going to break stuff if it does.

agreed. 75shot is preaty violent when it engages. I would imagine 100shot would put you in ur place

i didn't post it but i do plan on running a controller for the n2o. i'm concerned as to whether or not the stock fuel system will still supply enough fuel to keep from running lean.

ionNinja are you saying the stock system without the smt-6 will be alright with the 100 shot w/ controller of course? oh and i plan on adding a second 10lb tank for more spray, more stable output pressure and lastly i feel two tanks in the trunk look better then one.

Nice first post. why would you runa higher jet of fuel our systems already run rich and our fuel pumps probably wouldn't be able to support it.

you probably wouldn't need a 2nd bottle. a line pressure adjuster would be fine. more weight.

i thought of the weight issue however i do want the option of running both tanks just for the option of extra spray for those special occassions when you just gotta show your ass.

I think your over compensating for the spray. There is no need for a 5th injector as the nitrous jet acts as this. The stock fuel delivery system will be able to handle a 100shot no problem. The car runs rich as it is, it will be fine. Just make sure to run 91+ octane and colder spark plugs. If you have access to a Sunoco, then get fuel there, Ultra 94 is the best fuel around

if you were concerned about fuel with a 100 shot you would be looking at a fuel pump not an extra injector as you already have a source for providing fuel. but you should be fine...

I have 2 bottles and brackets for my car to mount a second bottle but I'm lazy. One is just for storage though since I didn't wanna have to run a separate bottle heater. I don't know if more than one bottle is gonna provide extra performance for you though as it still all has to fit through that n2o jet at the end.

It really wouldn't. I would just give constant presure for longer then a 1 bottle set up. Ur right, you can only pump so much nitrous through the jets.

i figured the extra bottle wouldn't pump more. i really want to make sure i got as much juice as i want when i'm having fun. i just want to keep the fuel right. i don't like the idea of blowing a second motor.

before you ask it was pre-nitrous and only had 24,000 miles give or take at the time.

fuel wise ur safe at 100shot. but IMO that is the limit. If you were to shoot 110 and above, I would strongly recomend upgrading the fuel and maybe look into upgrading some internals as you would be getting close to the 250hp engine limit

valves would be the only thing i would say that you need for sure. All other components shoudl be able to handle a 100shot.

damn man, i have no real input but you ever run it at a track? any times at all?? thats wicked never heard of anyone really on any street car runnin 100 shot

I agree but I would wanna take some extra percautions at 250hp mark as our connecting rods snap simotaniously, which would cause a severe engine faliure.

The GM EcoTec 2.2 engine build book states the highest safest shot you can run in our motors is 75. I wouldn't exceed that.

the build book states that a 75shot is the safe for a nitrous shot but during testing they actually did a progressive shot up to 125shot i believe and thats when the rods gave in. so a 100shot is a capably, just not recommended. also it dependes on the saftey measures you take with this shot. perfect air/fuel ratios, no detonation, good fuel and n2o supply. for a shot that large a progressive shot is almost necesary becasue that 1st input of n2o is a tourqe monster and somethign will bend from a 100shot instantly. so i would do like a 65-75shot then a 25-35shot.

In actuallity they tested our motors up to a 300 shot of nitrous. Thats when the motor took a poo. This is of course in a labratory condition. Perfect settings and environment. IN THOERY our motors can take a 200 shot of nitrous if exicuted perfectly.

300?! where'd you read that? not doubting you i just think i only read a 150shot. your talking about the 2.2l ecotec right?

I am. I read it in a tuner mag back in '05. Lord knows where the mag is now though. It was an article about the EcoTec motor and what GM didn't put into it's build book for the car.

Another neat fact is that 40% of what we have in our motors is the same in the 1200hp dragster from GM. Nifty.

intresting.

indeed
