What are you running now?

I would run a 6x.013", but that's me. Seems to be the cat's meow. (depends on the setup of course)

Have you done a little research seeing what other people are running with compound setups like yours?

i have yet to put the compounds on and the p pump right now i am just running the 62mm with a s/o vp with 150 horse 8 hole injectors and i dont know what it is but i got some seriously lag from it. i have more then enough fuel and when it does spool it takes off like a rocket but it deffinetly isnt performing at its peak efficiency. any way i searched and could only find people running a stock turbo over the s475. they seem to run 7x12 i think i can go a little bigger but dont want to be to big.

What are the specs on the exhaust side of that 62mm charger?

Check out "Tyler's Build Thread." Should be on page 1 right here in the performance parts discussion.

He's running a 62/65/.70 over 75/83/1.1 with 7x.013"'s.

Honestly its been so long I can't even remember the exhaust side but it is something like that. As far that thread thank you for telling me about it that is a pretty bang on turbo setup as me. So 7x0.13 I believe is 300 horse? It will be no problem for my pump to keep up to those just want to make sure it will spool both ok. Also in that thread with that setup not even tuned yet that guy was still getting a little over 18 mpg pretty impressive.

I'd try your 150's before you drop a bunch of money on new injectors. I'm running 7x10's (125hp) with mine, and I seem to have plenty of fuel to get the compounds spooled. You can always change to something bigger if you don't think you have enough later.
