Guess what Im going to have first time dyno on my 2006 silverado 5.3 on 94k mileage on it. Going to dyno this Saturday morning. I wonder how much hp will be. Im running 275/45/20 wheel/tires on it. I still have stock 17" wheel not feel like to change it. Or Should I? I have few mods on my truck

ALL most stock motor, gear, tranny. I wonder how much hp would be. I always running 93ontace gasoline on it.

 

I'd say ~275-285 rwhp depending on dyno and weather and a few other things.

 

Okay. I will post dyno and the video this Saturday.

 

Should I leave 20" alone or change my factory 17" for dyno?

 

just leave the 20's on. and I'm guessing 265hp

 

To compare 17" to 20" how much lost hp?

 

260 hp 280 ft lbs of torque. Just a guess

 

Why take them off? Its just going to skew your results if you daily drive with 20s.

 

Just like pulling weight at the track, you want to run the best you can.

Just like locking the converter on the dyno, better results.

 

Which gear need to be lock up for good result dyno?
