Truck was spinning pretty bad. You can see in the video out the back of the shop everything disappears....

Was hoping for a little more on the bottle. The N/A numbers are awesome, I could not be happier.

N/A 12.94@107.51 MPH 1.85 60'
Progressive 125Shot: 11.56@121 MPH 1.65 60'

 

great #'s there. how hard was it to put the 5.3 in the s-10??

 

Nice numbers. Definetly sounds mean,
Would like to see some more videos of it idling and drive by's if possible.

 

freaking sweet, great work man

 

Why such a small cam for a larger stall. I would think you could utilize atleast a 228 duration cam with your light weight and big stall speed. Never the less nice numbers man. One of the things that you can attribute to the low spray numbers is the relative low lift of your cam, I have noticed that on a few low lift cam dynos when the engine was sprayed. Are you experiecning heat soak with the BBK manifold some have had problems with it.

 

The cam was chosen for fuel Milage and durability. The truck was built to be driven and does a lot of road trips. I would love to run a larger duration high lift cam but i would sacrafrice fuel economy.

As far as the BBK and heat soak... I would think it has some effect on the performance but I chose the aluminum intake so in the event of a nitrous backfire it does not shatter. I would think its robbing a few HP but thats a sacrafice i am willing to make for the peice of mind that it provides.

I didn't dyno before the intake swap but this exact setup with a stock LS1 TB and Manifold did 104mph in the 1/4 after the intake and TB swap its running 107.5mph

 

Well it seems it made quite a difference. I understand on the fuel economy thing I figure this was a "toy" type deal.

 

Its a toy for sure, But I make regular 300 mile road trips in it.

Knocks down 29mpg at 70mph with this setp
27MPG with the A/C on

 

I dont like s-10's, but this one is sweet, I wouldnt mind having that for sure!!

with that mph is should be atleast a mid 12 sec truck n/a...

 

That was sick! Nice truck!
