I just picked up a MP112HH from npb4me and have some options. (BTW Dustin hooked me up with a great system) Anyways I wanted to find out what are the limits of the 5.3. It's my daily driver but I want to get the best results without sacrificing the reliability of the motor. I have been searching the forum and found some great info here but wouldn’t mind some opinions to point me in the right direction.

 

Radix @ 8psi, 5.3, GT2-3 cam, 90MM tb, good dyno tune and long tubes is good for low 13's at 104 in the crew cab your truck will run forever.

 

Didn't you lose one cylinder in yours? Or was yours pushed further than that?

 

Lost cyl 7 with the turbo and pushing 12 psi.

 

Welcome to the forum and welcome to another Ca member too. What are the limits of the 5.3 or what can you do and not stress too much? Lol, Brian you don't think I'm at the limit yet do ya?

 

naaa...there is 20 or 30 hp left in that motor !

 

Ohh ok it was after you switched. I didn't remember when it was

 

10-4. Now we are going to see what the TVS1900 will do on a forged 5.7L

 

will the tvs behave more like the 112/122hh where for a given max psi, they don't boost as well in the low end compare to the regular radix 112?

 

I will have that data soon.....More than likely after SEMA.
