Based on what you guys have seen with the mods on our trucks what type of hp and tq numbers do you guys think I'm laying down? After I have the ASP crank and alt. pulleys also the fans installed what numbers do you think it will raise up to?

 

Here is my dyno graph with similar mods... KN gen2, ASP, HPP3, Hamm Headers, true dual Magnaflows w/xpipe, e-fans, free mods. So I am guessing you will be in the area of 280 hp and 300 tq.

 

Ya, i bet thats very similiar to your hp/tq gmc5.3
which is pretty good, b/c your runnin SS power(345 at the flywheel) in a single cab. After the pully and fan install, you possibly could be gettin near 360hp, but im not sure how it all works together. If you get that power to the pavement, i bet you could run some descent 14 quarter mile times

 

I would say 250 HP no more than 260 tq no idea.

 

I use Penzoil Syn I doubt it that my truck would go that long. Why? just because I am on this board. Lead Foot is our name.
