I'll keep you updated.

So far, baseline with tune is 285hp/284tq

btw, we finished up that 383 with the tvs1900 but we need more boost! Smallest charger pulley and largest crank pulley is only giving us 10psi. (i'm open for suggestions)

The pic of the tahoe is not showing up

 

Wow, that's a big crimp at the elbow...good argument for the front inlet.

Is that a 5.3L/LM7? That is an excellent base motor to add boost to. Can't wait to see your results!

 

Looks noticeably larger than my 112. Looks like the same yr. as my Tahoe.
What other supporting mods does it have now?
I'm anxious for results too.

 

so is it a 383 or a 5.3 engine?

 

Ya, a 5.3L, '07 Tahoe.
6-8psi, custom cam

It's a TVS1900

 

um........how bout a centrifugal?
