Reading a lot of posts on here about 42lb injectors not working with pulley smaller than 2.8 why. Also bought the stage III kit from cobalt addiction if this is a bad combination why would they sell it that way?

thanks for the info in advance

pushing the limits of the injectors...u gonna run real lean and with out the proper octane fuel u looking at and ugly situation

 

when you say proper octane you mean 93 it would it have to be higher

 

When your forcing that much air into the motor the injectors can't deliver enough fuel to keep a safe air to fuel ratio...... Boom . Thats my understanding anyways , i could be wrong .

 

thats exactly right

 

just buy some 60's, a real tune and a 2.7. oh and cooling mods. you'll be golden

 

get 60s they work awesome
i had 45s with my 2.8 and i was only pushing like 180whp

 

wow that sucks lol

 

i hope your lieing....

but get some 60;s and a 2.7 and a tuneee yoo

 

i installed my 60s and got a tune, now im at 237whp and 227 torque

 

what other mods do you have?

 

2.8 pulley 60lbs injectors and a tune

 

lol so u had 40's on a 2.8 and got 180whp?? i imagine them dyno people laughing at you...

aslong as its fixed now..

 

thats awfully low for 60's 2.7 and a tune

 

i bought it like that
i didnt relize it till i saw that the injectors were green
the guy that had it b4 me must have been stuipd to have that set up

 

Me 2, I just ran on the Dyno with 42.5 & a 2.8 with 244 hp & 231 wtq, Sounds like you got a really bad tune!
My A/F mixture on 3 runs was 11.60, 11.44, 11.40
My timing advancement is 16.5
0 KR
IAT's were 90 degress & temp outside was 87

My tune is very conservative!

 

Good numbers and AFR but what was your IDC at?

 

im very curios as too what those #s were as well

 

hmm someethings wrong there if ur pusihng that low of numbers on 60's and a 2.7 hmm wow

 

You need 60lb injectors

 

i need them too then im gonan drop to 2.6
