That book is THE BEST book I have EVER bought !!!!!....I've read and re-read it many times !!!

 

You will get more power to the wheels through a 4l65e and a 4l60e then through the big ole 4l80e. That is where you are losing the power but gaining the reliability.

 

another fact I did not know.

the LS6 camshaft on the way it was made.
the diameter on the lobes is cut smaller to give the camshaft a higher lift and needing a longer push rod, ( aka sewing machine effect with shorter rods).
when switching to the LS6 camshaft the LS6 push rods need to be used as well in order to get the full lift out of the cam.

so for thouse of you guy that have the sewing machine effect going on, you are not getting all of the power from your cam.

i saw this sitting on the shelf at walden books with a buy 2 for the price of one.
i did not grab another book so i paied full price for it,
all this time i have been looking for the LQ9 and to find out from this book that the 6.0 i am looking for to supercharge is the LQ4



had to add this,
to increase performance to the stock truck air box, cut 3 1" inch holes in the bottom of the air box to increase air flow, unless you are going to try and cross a river, or drive fast on flooded streets then do not do it

 

The Denali has a different exhaust then a 2500HD.

 

Interesting... Well, then it looks like it's time for me to crank up the boost!!

 

I think the difference in the 25 h.p. rating is all in tuning and as already said exhaust setup.

 

I think I will save my $15 and do research on LS1 Tech.

 

Weedo, one of the main reasons that you seen higher hp numbers then a regular 6.0 in the 2500's is that the 2500's have the 4L80E. The 80E robs much more power then the 65E that we have in our Denalis. Exhaust and tunning are the only engine differences between the two. I imagine that stock for stock your yukon denali would dyno higher then my sierra denali, I say this becuase they put Dana 60's rears in the Sierra's where as the yukon has a 8.5 I believe.

 

I bought the Will Handzel book awhile ago-lots of info-all I need is to win a lottery..

 

Aren't factory HP ratings determined at the flywheel? In any case, the higher static compression ratio of the LQ9 (along with premium fuel) is the biggest reason for the 25 hp increase over the lower compression LQ4. If you're planning to increase cylinder pressure by turbo/supercharging, the LQ4's lower static compression ratio makes it a better choice when compared to the LQ9.

Beyond that, what sort of drivetrain/exhaust you connect the engine to determines how much power is left to move the vehicle.
