Is it safe to run a 2.79 pulley on a gm stage 2 tune, if not whats the smallest you could use on a stage 2 tune safely

 

i personally always though it was 2.9 that was the smallest u could go on regular stage 2 tune..thats what i was gonna do to lean out my car when i slap on my stage 2

 

hmmm

 

from what i have heard and been told, u don't really wanna go lower than 2.9

 

a friend of mine has a 2.8 on a stage 2 tune......so i guess thats not good

 

some people run 2.8's w/ stage 2 no problem, but the damage may happen depends most likely on what cooling mods you might have and how hard you drive your car. I prefer 2.9" i don't have the guts to go lower unless i get a custom tune and injectors.

 

yea its a friend of mine all he has is the airbox mod and he drives the **** out of it

 

Yeah, thats probably a bad idea, at least getting an exhaust may allow for some breathing room. With just intake mods all you get is heat and pressure build up from the supercharger.

 

so to be safe with a 2.8 and stage 2 tune what cooling mods would u recomend

 

anyone else...........is it a good or bad idea to run a 2.8 on a stage 2 tune?

 

you should be fine with just stage 2 and a 2.8 no cooling i have a buddy thats ran that for 2 years or so no problems..if anything shift at 6500rpms cause of your idc

 

a guy i know that has it says that stage 2 runs to rich and that the 2.8 evens it out nicely........this is a question for anamolous to answer!!!!!!!!!!!

 

Can you run a 2.8" with 42's? Sure
Will performance over 6000rpm be lacking with that combo? Yes

Want a 2.8" You WANT 60's or 50's

 

so the finaly question is.......if i want to run a 2.8 on a stage 2 tune i would have to get a custom tune? or should i just individually but injectors 60's etc...then custom tune

 

can you tune a 2.8 and 42s with hptuners to make it work?

 

so pretty much you got a buy things individually to make it fast

 

It can be done, and with proper tuning it can be made better.....with tuning and meth it can be made safe.

but just running 2.8 on the stage 2 setup is not what i would call safe.
its not OMG gonna blow up in weeks dangerous....but its not a setup i would suggest running for any long period of time.

 

what about a cobra h/e instead of meth?

 

60's, 2.7", HPT = Enjoy

 

the meth is making it safe by supplying the fuel (meth) that the injectors cant keep up with.

its not the cooling properties that makes a 2.8 pully doable....

hence a H/E will do nothing for the IDC problem

 

Meth is a bunch better than the cobra h/e...hell if I had hp tuners and some tuning knowledge I would go with meth, cobra h/e, and the intercooler plate...though I am just going to go with the last two since I have neither the knowledge or the software haha.

Edit: please do not go any lower than a 2.9" on stage 2 and if must only go down to 2.85 max.

 

its all just confusing because on cobaltaddiction they have that 2.79" pulley for sale and it says that it runs better on stage 2 soooooooooooo

 

IDC's with 42's and a 2.8" are bad.

 

Deffintly would not trust that...of course they want to sale the product and i mean of course a smaller pulley equals more boosst...though I say it will run it too lean and make everything hotter which is not good on #4 piston at all.

I would recommend cooling mods for anything below a stage 2 pulley which is the reason I took my 2.9" pulley off my car was I realized that I needed those cooling mods to optimize the pulley. Especially during the summer.

 

in their defence, for a good while, 2.8 was the golden mod.
everyone and their mother was running it on the S2 tune.
before people started realising the IDC issue....

alot of people have run it successfully with no issues....

but that doesnt mean its "safe"
