my mods are in my sig. how safe is it to run a 2.7 pulley? i would like do run it but don't know if its worth the risk. or if it is a risk? thanks.

you should be fine...you have both 60lb injectors and a methanol injection...your good to go

ur good to go bro. but a h/e is not a bad idea sometime in the future

ifknrock09

i was looking into a heat exchanger. i will more than likely do that here pretty soon. just need get a list of what all i will need. then start rounding it up.

Stick with the 2.8.

h/e dual pass and ur golden bro

a 2.8 is the most efficient on our superchargers but you can go to a 2.7 with meth injection no problem...a 2.6 is even sufficient with meth alone...however a h/e would be a nice compliment

LopsidedJester

yeah, i wouldn't go past 2.8 IMO, 2.7 will produce more heat, with meth injection it may help a lot to cool, but you're still going to reduce the life of your supercharger that much more. Plus i've also heard about rotor growth on the smaller pulleys, where the rotors spin so fast with so much heat that the tolerance lessens and they scrap eachother causing the coating to come off and the supercharger to become even less efficient.

i've heard that to jester tho i havent heard alot of it...i'd say the stock blowers are holding up well so far....and i'm sure there are alot of ppl out there on 2.6 and 2.7 pulleys an arent having any problems to date

ifknrock09

i think that i am gonna buy one and hold on to it and get a heat exchanger too.

yeah man, cool the car down first. then heat it up

Am I the only one that noticed this thread is in the wrong forum!?!? How the hell does this qualify as "ADVANCED performance"!?!? Seriously, this forum was made to get away from the pollution of threads like this that could be avoided by simply using the search button!

I'm sure 2.7 is fine, but why drop 1 size pulley.. how much power do you expect to gain.. I don't know the numbers thats why i'm asking

Moved to tech 2.0 this is not advanced

DONT DO IT!! YOU WILL BLOW UP YOUR CAR!! YOU WILL SEND A ROD THROUGH YOUR HOOD! FOR THE LOVE OF GOD, DONT RUN THE 2.7!!! IT'S THE DEVIL!!!

restonSS

haha i was like wtf???

G85 SS

You're good but I don't think you will see any gains from it.

restonSS

you will see gains or everyone would be at a 2.8 and not a 2.7. with the meth you are fine, but i def. recommend getting a h/e. both of them offer great cooling; dont waste your money on the dual pass. ive heard it doesnt do much at all

ralliartist

na, the dual pass works great with the extra h/e. The dual pass by itself is not too much of a gain.

restonSS

i stand corrected

theneelster

+2 lbs of boost maybe 5hp? But you have to tune for it...err...you should tune for it.

ifknrock09

look out for the hardass. i love how opinionated people are.

but as for running a 2.7. i am ordering one in a week or two. it won't go on for a while though. i am gonna save up for a few weeks and buy a dual pass. plus i need a wideband so that when i get retuned it'll be perfect.

ralliartist

don't take it personally, it is a pain in the ass to install so that's why most don't do it. And the ones who have done it, I have no idea why they don't add a second h/e.

restonSS

when i took off my supercharger i saw the stock one. it seemed pretty easy to get at IF you take off the supercharger. Once you know how to, it takes mayb 10 minutes to take off the supercharger.

Red Rocket SS

I have had mine for a year now, no problems. I did notice when i ported my blower, that some of the coating was coming off. My brother has a 3" at the time and some of his coating was coming off to. So, i dont know what that means to you.
