well as of now im runnin a 75 wet shot and im really happy with the off the line part but after bout 70-80mph its not pullin as hard as i thought it should. anyone think a 100 shot would hurt my lil 2.2? now i know hack is gonna say go for it since he's runnin a 90 shot now but im lookin for other opinions too.

 

do you have money to re-build ?

 

I would try to stay content with the 75 shot if I were you.

 

na not really.. thats why im hesitant to up the jets right now..

 

i think ill be fine with 100 shot , all im going to say is watch your rockers and make sure you have the correct jets , remember the cobalt runs way rich till redline then it starts leaning out. know your car, get it dynoed and dont LET PEOPLE DRIVE YOUR CAR

 

yeah thats what i figured i should do but i didnt think it would hurt to get some opinions on it.. dont get me wrong it pulls like hell from a dig wit the 75shot now..

i think i may try it out once to see how it does but i just dont wanna take a bigger chance of blowin it up. i just got n2o to hold me over till the first of the year then imma order a ss/tc.

anyways thanks for the fast input guys..

 

Do you have the 2.4 manifold? I bet that would help higher up with the nitrous added on top of that.

 

you know thats one thing i havent got so far.. man i can't believe i've forgot about it.. thats the nest thing on my list then.. that'll make it a full bolt-on motor too. thanks for bringin that up man..

 

You got it.

I imagine that the extra kick from the 75 shot will really shine with the 2.4 manifold in the upper RPMS.

 

yeah that would help out alot. i guess i'll be orderin one next week then..

 

been there done that, wasnt to great of a feeling.nitrous is to addicting for me, i needed something that was consistant.....

 

But you let your friend drive.

 

lol it is addictive huh? every time i spray i feel like a crack head tryin to get just one more bump...

 

the only thing i would be starting to worry about is your fuel system. if it can keep up with the demands. i know your running a wet set up but still. your fuel pump still has to play catch up.

 

A good rule of thumb is 20hp shot per cylinder. 4x20=80 shot. Thats about the highest you should go

 

i've thought about the fuel demand for a bigger shot. top end right now dont seem to put out to well on the 75 shot im runnin now for some reason. im sure it has somethin to do with the way the fuel cuts back to keep it from pullin hard at higher speeds though. anyone think a tune from terifca would help that problem for the top end pull? when i say top end im not talkin bout tryin to spray to go way over 100mph either. im talkin bout when im sprayin from the 60 to 100 range.

 

its recomended by most niitro companiesthat you do no more then 20HP per cyl on a stock motor. Im only going to be doin 50 shot on my G5 GT 2.4L. And its getting tuned by a laptop setup, no dynos around here unfortunately. But they said if i use it without the tune i will blow the engine even on a small shot because the rpms on the window switch are not setup and the air fuel ratio needs to be setup with the nitro .

 

 

also a 2.4TB with a tune would keep your car going hella strong above 4k RPMS

 

are you running nitro or nitrous? they are different.

 

lol nitro huh..? must be playin wit a RC car.. im runnin a 75 shot now and havent blown the motor yet. hell hackabuse is runnin a 90 shot and has been doin so for a while now and hasnt blown his either.. a tune is not needed to run nitrous.

 

ur right...but caution is. Rollermandan (i think) blew his intake mani apart when he had a nitrous hiccup...

 

That was the result of a malfunction though.

If you got a wideband and a progressive controller (try dynotune) you should have no problem.

 

o hell yea caution should always be used when sprayin..

hey hack how does your car pull after you get around the 70mph mark when you spray?

 

Mine pulls great until i hit 3rd gear around 75 then it kinda dies down a little bit
