Ok thanks! Are you running a ati damper 8 rib? I was running around 9.5psi on the 2.8" blower pulley but when I did the cam it dropped to 8psi. Where did you get the 2.7"? 2.8" was the smallest I found but that's a 6 rib never looked into 8 rib yet. Thanks

 

my 8 rib is a left coast 32 kit. he has the 2.7 pullies.

my damper is just a power bond. looks like stock, but 10% larger. its cheap.

 

Where do I buy these left coast 32 kits?

 

Just wanted to give an update. I got the innovators west 8 rib set up with a 2.7" blower pulley and a 10% overdrive crank pulley, made an intake tube to run a cold air and added meth. I now need a fuel pump and bigger injectors they are maxed out and dropping fuel preassure pretty bad at wot. She put down 598/592 much better! Tuner said I'll be well over 600 when I get a fuel pump and injectors!

 

I bought a TVS1900 for my 12 6.2l. It came with pink 42lb @58psi injectors. WAY to SMALL. My stock 52lb injectors were at 99%idc. I was at 8psi. You should be using meth at 8psi. I had same setup as you but stock cam on 285/50/20. 436hp 435tq

 

Mine came with black injectors. I didn't have them bench tested but the tuner said they were bigger than stock from the data logs and thinks they are 65lbers but I have no clue. I guess the drivetrain on these trucks eat up a lot of power or the tvs1900 is just too small and inefficient for the 6.2. It made ok numbers but was expecting more

 

Did you ever upgrade the pump/injectors and redyno?

 

No I didn't. It's safe where it's at. The trans in #1 on the list. It's still a stock 6l80e with a stall converter. It's doing better than the shop that I got it tuned at thought. They said it'll need a trans before winter but it's still kickin haha

 

How many lbs of boost are you at now? I'm sure it runs real strong with that much power.

 

It's right around 11psi. And ya it runs great I love it. But always want more!
