GMPP intake vs Ls6 intake for turbo
I love my setup, but would like another 150-200hp. So, id like to change my cam, and my intake setup. I have a GMPP carb style intake laying around... ive also got a lingenfelter GT11 cam, but i think its going to be too small.
My questions is would it be worth it to switch to the carb style intake with my setup? What kind of cam should I be looking at to match it?
I heard the ls9 cam was pretty nice. The biggest thing is I dont want a big lopey cam, Id like to keep driveability over an extra 10-20hp.
Any input is appreciated!
IMO stick the gt11 in it, and something like an st80 (what zombie was running IIRC) and you'll be set. you'll want springs with a decent amount of seat pressure too, ~145lbs or better, if you dont already. i'd really take a look at zombies thread if you really wanna make the most of this rear mount setup...
Going with a larger turbo would mean Id come into boost later? Id rather, at this time, do a cam ($200-350) versus a new turbo ($1000)... if I could get the same results. Yes I understand I could get much more with the turbo, but i like to see what this setup could do maxed out before changing anything big. Eventually id like to do a 408 and turbo upgrade, just not yet.
I dont think the GT11 will get me there, as its pretty similar to the LS6. Anyone have an opinion on a cam? ls9?
A cam change won't net miraculous HP gains.
Modular Turbo is selling units for $650-700 to get you where you need to be. Obviously you will need a retune and probably larger injectors/fuel pump to deal with it.
Since you are in Vegas you should look into running e85 or e98 ethanol.
