I am going to be installing the 60 lb injectors gmpp perfromance cat back,intercooler dual pass mod cooler plugs and eventully a header.My question is this. Is there much differnce between running the 2.5" pulley and the 2.6" or will it be overspinning the supercharger? Is any one running the 2.5. This is my daily driver any recomendations.
Thanks,Chris

 

I've been running the 2.5" for months with no issues. It's only "overspinning" the blower for a brief couple of seconds, about ~6500rpms. It's not enough to cause damage, or atleast hasn't yet. There's a nice torque gain going with the 2.5" over the 2.6", however the 2.5" does create more heat. Make sure the car gets a good custom tune either way.

 

Agreed.

 

For a daily driver I would say go with the 2.6. just my 2cents

 

I have the 2.5 with tune and no problems as well.

 

I am running 2.6 now will go to a 2.5 once I get more cooling moods, and headgasket/studs

 

im about to go to a 2.5 with a tune from tag, im just really worried about it being a daily driver and making the 5 hour trip to wisconsin from STL about once a month

 

Do 2.6...2.5 won't gain that much more hp unless you have a lot of cooling upgrades on your car. I have a 2.5 with no cooling upgardes and she's still holding up STRONG! (besides my broken actuator lol)

 

the torque off the 2.5 would be a nice gain, i dont do it only because im not down with shaving the snout.

p.s. memphis your headlights are SICK... i wish someone would have made some for the rl

 

lol thanks, that pic in my sig was taken 6:20 in the a.m. right before work lol...it's what I do before work, take pictures....i get bored
