Hmmm. Maybe I am used to the bigger superchargers or turbochargers adding 22ish hp per psi. I am not sure if 18 is good on the 1900 honestly.

 

I just weighed my 2010 ZQ8 Crew Cab at Englishtown this past week. With almost a full tank of gas, Undercover Ultra tonneau cover, bed rug, and baby seat, it weighed 4360, so without me it would be 4170. Of course I don't have those big tires which do weigh much more than my low profiles. Just a FYI for the difference in Colorado/Canyon setups/model weight.

 

dang, that is a good difference. i think i need to trim some fat! lol

 

I think my Colly 5.3 3LT-ZQ8 2 door ext cab was 4050lbs on the metal yard
scale.

 

At what power level do these v8 colorados start breaking the stock transfercase and front diff in 4x4?

 

Impreasive, i wish they would come out with a v8 version on the new body style would be slick *** truck.
