I'm looking into buying a stage kit, but I am reading so much about not getting a crazy small pulley ( <2.8). I have not seen a stage kit yet that comes with any cooling mods. Does this mean that you really don't need cooling, or that the kits simply DO NOT come with the cooling mods? What's the safest, smallest pulley to run without having to do anything "crazy" with my engine?

Thanks,
Nick

 

I think 2.8 is the smallest you should go without cooling mods...I believe cobalt addiction has a stage kit with the dual plate included also.

 

Alot of weather you need cooling mods has to do with your other supporting mods and how you drive, along with the actual weather where you live. If your not romping it hard all the time, it is temperate to cool, and you have something like a full free flowing exhaust, you can easily get away with a 2.8" pulley. If you run it up to redline all the time, drive really hard, the weather is hot as *****, and you don't have any flow mods, then with just the stage 2 pulley you'll get heatsoak.

 

Do not run a 2.8 without cooling mods like meth... I have a 2.85 and it was pushing the limits without any kind aof cooling!

 

do a dual pass. U dont really need it for the 2.8", but it can only help.

 

I would say 2.9" is the smallest you should go without some form of additional cooling. These things just make too much heat once you get past 15 lbs. Heck... I've heard some say that the stock HE system isn't even good enough for stage 2.

 

Guys... sorry to tell you the dual pass didn't really do much to warrant the cost! Meth injection is much much better for the money!

 

All i have to say is that GM sells the dual pass with their stage 3 kit for a reason and thats a 2.99" pulley, but i'm sure they're just bein.g on the safe side. I know you can get away with a 2.9 and a 2.8, but like infinityZen expained, it depends on how you drive

 

depends where you live, and how you drive.

pully has far less to do with the need for cooling mods than both of the above factors.

 

nice info guys a kunamatada

 

Stock pully size = get cooling mods

I still have the stock pully and have a cobra h/e sitting in my garage ready to go on. I want to do the supporting mods first, so I will make sure the car runs cool before giving it more stress.

 

So whos the chicken **** person who neg repped me for my post! Look... when we had our dyno day here in KC a month or so ago, in 100 degree heat, we have a full GM Stage 3 car, and with the dual pass wasn't running any cooler than I was, or anyone else for that matter with no cooling mods, meth injection seems to help the most of any cooling mods I have seen and for less than 200 bucks it's a bargain as well!

 

i have logs to prove mdubs post being accurate.

if needed, i can go log the car again, vs his car, or a stage 2 car.

you can get over 250 fwhp out of the stage 2 pulley

 

that makes him a chicken **** cuz he neg repped you?

 

No because "he" didnt' say who "he" was.... that is why chicken **** was introduced!

I always put my name after every rep positive or negative!

 

im stage 2, and have seen nothing but ambient IAT's using HPtuners around town or at the track at WOT. probably why i hang with my buddy's intense stage 4 car

 

For sure... watch out Hatrick you'll get neg repp'd in here because people don't like the truth... And just tyring to give some advice so people don't spend money on parts that are really unneccessary.... But it's okay!

 

living up in the great white north as i do (Michigan) i have gotten away with a 2.8 pulley. but some kind of cooling mod is definitely next on my list.

 

relax man

 

Oh, I am fine! Don't have to tell me to relax.... I am as happy as a clam! But if people don't like adivice they shouldn't ask for it!

 

mmmmmm i love me some neg rep. if my buddy wasnt deployed right now he would say the same thing so could really care less. i would love to run some cooling mods and a 2.85 though... but i think i want the NAAAAAWSSSSSSss more

youve been around since '05 you should know thats the general mood around here

 

True I know!

 

+ rep for havin common sense....

 

Damn Stu your car with a 50 or 75 shot would be insane.

 

i know this! if only i had the DR's still, id be hitting up that 10.50 class!
