O.k so im going to be running a few 1/4 mile trips tonight. they have 100, 110, 116, and 125 octane race fuel there.... im going to be running a 65 shot of nitrous. should i use race fuel? my technician is saying it would help. i just dont want to ruin anyhting. please help!

 

Make sure whatever you run is UNLEADED
I would think 100 would be plenty

 

whatever u use, show us time slips tomorrow. haha.

 

If anything i dont think i would go higher then the 110, but id still b a lil worried bout the 110. 100 would prob. b the safest thing. Cuz out of all the forums bout cobalts dragin, they all seem to use either the 93..normal or the 100. And they are gettn n the mid to low 13's + other mods. One as low as high 12's. Hope this helps u out some. And yes post the slips.

 

honestly, i would use 93. if you're dead set on using race gas, don't go over 100. 100 may even hurt your performance depending on your mods.

 

I wouldn't go over 100 octane... and make damn sure it is unleaded... leaded gas will really **** your system up.

 

bah... how about you go ***** in on this one... go 125, I want to see what happens... ;0

 

as stated.. i would run pump gas.. if your gonna do it no matter what then get 100.. you dont need that cold of gas.. gonna mess something up if you do...

personally.. just go grab you some 93 and get an Octane booster to bump the points up by a couple.. probably get your aorund 96-97 octane

wont be much to see...

 

I assume there wouldn't be unless it was done over a long duration... but with nitrous I assume anything is possible... if the car shot puppies out the exhaust while using nitrous it wouldn't surprise me a bit.

 

c125 is way to cold.. there would be plenty to watch.. but your gonna be watching something you dont want to see..... they use that in nitro coupe/top fulies

 

im not set on doing anything. if it is going to help i would do it. but why pay more if its not going to help? thanks for all the info

one question, are the mid 13's with nitrous?

 

what are your mods? you can hit mid 13's with stg II + good driving

 

my mods are in my garage. theres alot. i want 12.5

 

You can only really burn 100 octane effectively. The 109 won't burn completely, and will be a waste, though a good safety factor. Stay unleaded or it could destroy your O2 sensors really quick.

 

I'd get to the track and just throw a gallon or two of the 100 on top of the fuel you've already got in the tank... will give you 96 octane or so... that'll do fine.

You won't see any huge gains off of going with a higher octane unless you have a way to tune the car specificly for it.

 

no chance with your mods, being realistic. maybe low to mid 13's at best.

 

dont run leaded fuel through your stock motor, the leaded fuels will dry out your valve guide seals and can cause engine failure.

 

I have H.p Tuners. - lol, i dont know how to tune though.

hum, without n2o people are running low 13's with my mods acording to the official list. unless im reading it wrong.

 

im assuming your running slicks yes?
the mods in your sig should get you low 13's i think.

maybe 12s with slicks and some really good driving.

 

That would be the statement that determines 12's, 13's, or being towed home.

 

i have nothing done to my car that would make my car need to be tuned. im sure it would help. but i dont have 60 lb. injectors or a really small pully or anything.
B.T.W- thanks for all the info!

 

minimum of 110
have a cat?

 

yeah. i have a cat

I guess the way i see it, the nitrous needs to be as cool as possible until spark. will this effect the nitrous in a negitive way?

 

If you have slicks and are not used to them yet, call the tow truck ahead of time. Last time I ran on slicks I had to wait 3 hours for the tow truck. :-( I was used to them in the street, but when I got to the track they gripped so hard that I broke an axle right off at the wheel, and that left the car dead on the track.

PSYKOSTEVO <---- Singlehandly responsible for more broken axles than the rest of the cobalts in my state combined

 

nope, just softer tires. not slicks. i'v been racing with slicks for a cupple years, just never on the cobalt.
