2.5 pulley? advice needed.
hey ive got a 07 ss sc with ottp stage two, whichincludes the 2.8 smoothflow pulley. i didnt wanna drop sizes any more than that cuz i didnt have any cooling mods. but im buying a meth injection kit, and im considering the 2.5 pulley. think it will make the supercharger spin to fast and damage bearings and what not? i want my car to last a while, but i wanna squeeze a few more ponies out before i go broke on the TVS.
oh and if i put the 2.5 on it, will it run right so i can take it to the tuning shop?

Idk man, alot of member run the 2.5", but reliability will be a factor. You should have cooling mods on now with that 2.8", and you cannot rely on just meth injection for cooling with a 2.5". and yes retune because it would be beneficial to run e85 or bigger injectors.

People have run 2.5" for awhile with no cooling mods and gotten away with it. Depends on how hard you push it and how often... Just don't do back to back pulls without a bunch of cooling mods.
I'd recommend all of the cooling mods such as dual (or better single) pass, aftermarket H/E, option B, etc. Meth will help but it isn't absolutely necessary depending on how the setup runs. I'd certain recommend an Interceptor also to monitor the IAT2's. A retune will be necessary as the blower will be moving a lot more air earlier. Porting the blower can also help a little.
I never had a problem with running a 2.6-2.7 on my dual pass, zzp s3 w/ option b, ported blower.
Just be careful...

Lol. 2.5 pulleys are good for a short time. Uneducated? Lol. I know an handfull of people who ran these with all the cooling mods and they regret it. Also running 42lb injectors on an 2.5 is just simply retarded, unless you want the car to run for a short time but lile the rest of us here we like reliabilty, and want it to run for an good amount of time and 2.5 isn't the way to go. So can anyone on here say they ran the 2.5 and it ran for more than an year please chime in. And you gtfo

Then you don't have the *****
Troyss you are a ******* troll. Have YOU ran a 2.5? ****, I ran a 2.5 on my car, only a dual h/e setup and ran it FINE for a year. No methanol, stock header, 2.5" catback. 13.2@108. Sold that blower tho and never shaved the new one down to do a 2.5 so I stopped at 2.6
I tuned a 2.5 pulley car and it is still running fine. Going on 2 years now. No issues other than clutch. Dyno'd 289hp/251tq

Man these threads get ugly FAST. Im gonna agree with Snakes709's statement. With 80s, e85, all the cooling mods you can throw at it. You can see some pretty sick numbers with a 2.5. Enough of all the negative bullshit in all these threads like this.

I was on a 2.6 with no cooling mods for over a year. No problems. Just don't drive like an idiot on the street. At the track if you don't hot lap the car... and keep the rpms up while staging your IAT2's will stay cooler. But i seriously wouldn't recommend it lol
Do as I say not as i do
