So i finally got around to putting the new pulley on. I have had just the stage 1 kit for a while now. Holy crap I was impressed. Got on the freeway this morning and dropped it in 2nd and punched it, its crazy how much faster it boosts now with the new pulley. Feels like its pulling harder now and the whine is even louder. I love it! Just had to share haha

 

try a 2.7 2.5 is insane!

 

congrats

 

Nice!

I also want a 2.9!

 

I want to go with a smaller pulley but i need injectors and want to get rid of TM first.

 

Im going to a 2.8" when I get he money...I cant wait!

 

42# and a 2.9" should be fine with the occasional 7k sprint. On the TM side, I had a scanner on mine the other day to measure my iat2s because I added a cobra h/e and it said I had 13% torque reduced.

 

Nice man, glad you like it.

 

hello 2.80 pulley here and it just make you wonder why gm dint do this car stage2 from the factory to start with!

 

I would have to disagree with Mike on the 2.5

That will end up in a blown engine

I have said that since the concept of the stg kits. GM did this car all wrong and then milked the consumer for more money.

 

2.7" and smaller pulley's should have 60's with proper cooling mods done first.

IMO exhaust should be done first before even thinking about a pulley.

 

Frank 2.5 works fine. It's all in the tune. I went to 2.7 cause I don't need that crazy of a car.

 

I would say 2.9 +exhaust

2.8 + exhaust and 60# + tune

2.7 and under - new manifold + exhaust + 60# + tune + H/E

 

All right a newb question. What is TM and why do you want it off? I keep seeing it mentioned and have searched to be unsuccessful.

 

Waylin told me someone blew their car to **** with the 2.5 and a good tune. I guess my faith in this car isn't all that high.

 

i cant wait to do my 60# injectors and my 2.7 pulley

 

2.8 on stock injectors and a stock tune is not a very good idea. I suggest you research a bit more before you go along with that plan.

without cooling mods yah car might run super lean in the desert if we are refering to Waylin22.

 

yep good ol waylin

tryin to hot rod in 110* heat

For my cooling mod I have a fire extinquisher that I occasionally spray on my engine

 

Torque Management. You want it off because it reduces the torque a bit.

 

More like A lot

 

tm ftl!

 

Torque Management

why off I'll leave that to someone els



edit: Never mind

 

As in reducing boost???

 

^^ No, TM reduces torque. If you remove TM it gives you all your torque with out the PCM taking it away. Boost is not changed.
