^ either full cooling mods (dual pass, new HE, optB/stu mod) and meth, or if you lacking one of the above, compensate by running a more conservative tune

 

2.8, how much timming are you going to run? sounds like your going to be runnign a setup close to mine. what plugs are you going to run? what are you going to gap them at?

 

i voted 2.8 and feel good about it

 

hey i think i met you guys... was your car the one with the idle issue, and your buddy had the 2.2 turbo? i had the black TC, good meetin you guys... hows everything runnin?

 

So. What were the results?

 

Truth. I'm going through this right now.

 

^^^^^^^^^^^^^ X2

 

yea that was them are you on SEE?

 

I have 2.8/60 injectors. Love it, even tho my tune isnt finished I love it. Personally i wouldnt find a difference between 2.7 and 2.8, its .1 of an inch...not that much in difference. That being said, 2.8 is border line for needing cooling mods. I ran 2.8/60 during the summer with no cooling mods at all and the car ran fine. Just recently installed meth and h/e and changed the tune a tiny bit, not alot but i got timing moved up i think 4* with no knock. But since you dont have much cooling mods right now id say 2.8 is the best bet.

 

2.6" pulley, 60's, 2step colder plugs and ZZP Front mount heat exchanger are installed!

290HP and boosting 20-22PSI (the boost gauge just bury's itself)

 

Told you to go with the 2.6 .

 

You're running a 2.6 and only a front mount?

I must know your IAT2's....

 

Hell be fine.

 

i'm curious because i want 290hp

i was under the impression that without duel pass, meth, option b, all that goodness your **** blows up quickly.

however, when results speak... i ignore everyone else.

 

.. Exactly.

 

people just became very overly paranoid of running smaller pulleys without all cooling mods. you just need to compensate for it in your tune...and not do too many back to back pulls at once

 

Hm. That gets me reconsidering my performance plans for the year... Considering my car is a DD with the couple times a year track day, back to back passes are no concern to me. I just like to have a semi-speedy car.

I still want to know the temps though

 

I am tuned by 06black the best tuner to ever come across any cobalt. 06Black himself ran a 2.5 for years without anycooling mods what so ever just to give you an idea of how paranoid people are with cooling mods. However it isn't a bad idea to have the cooling mods just because you would rather be safe then sorry but like 06Black always says you don't need them if you have a good tune.

I also have the 2step colder plugs.
