I am subscribing in the hope of getting numbers. Your kit looks great, and this is what I want for mine when I get back from Germany.

 

Wanting power numbers or times for reference with your truck?

 

Both if possible. I already have the approval from the wife on it, plus it would make a great addition.

 

For reference:

60' = 1.911
1/8 = 8.262 @ 85.81
1/4 = 12.896 @ 105.19

Basically the same truck as yours, but without the stall and running 8 PSI which you likely will not get with the stock whipple pulley and the longtubes that you have. I was only seeing 6 PSI with the stock kit and 1-7/8" headers.

 

Got under it today, and found what looks like a stock stall. At any rate, 12.8 is great! You could easily slam on some street cars with that!

 

Well...I was planning on updating this thread this morning with some 1/4 mile numbers but mother nature had other plans yesterday evening. My Dad and I drove 2 hours to the track only to turn around and come home because it was pouring down rain. Oh well, I am going to attempt again next Friday.

 

It's Friday all day... I look forward to it. I hate precipitation, it's useless other than watering plants. Here in DFW it hardly ever rains, and if it does, you saw it coming. I feel for you.

 

My prospect list just keeps growing lol. Thanks for all the info on the whipple. I will be putting funds together to do this ASAP. Me being 2WD will make traction a thing of the past I'm sure

 

I just ordered my whipple kit. Should be here the early part of next week and installed shortly after that. Ill let you know what kind of power my 08 sierra denali puts down once it is installed.

 

Is there any reason that most are going with the 2.3l blowers instead of 2.9l? I know the 2.9l will make more hp but does it really raise the powerband enough to where the 2.3 is that much better for a 6.2l truck?
