Hey all this is my first post. I just got my AFE intake in today for my 2011 6.7. im still waiting on my afe exhaust, afe egr delete, and my spartan tuner with the warhammer tune.
There is a reason everyone goes with H&S. Everybody who dynos with Spartan, gets dissappointed. And you can't beat the customer service!I went with spartan simply because everyone goes with h&s and i like to be different. Also im interested to see what kind of perfomance numbers spartan will make in my 6.7. i here it makes more horespower but i havent yet seen any torque numbers. Yes my egr delete is made by AFE says the guy at XDP.
I have always wondered if the rear end gears give different numbers. Do you know what identical trucks but let's say 3.33 vs 4.10 gears would do?I run Spartan and can tell you my truck made 36HP more than H&S and 200FT/LBS more torque vs an H&S 6.7 on the same dyno.....here is my dyno graph I posted.
It my personal opinion that a shorter gear IE (4.10) will make more torque on the dyno but most people will tell you gears won't and don't effect dyno numbers. I can tell from person experience it did on my 6.0L...went from 3.73's to 4.30's and picked up 60 or so ft/lbs of torque. That is all the proof I have. Bigger tires I also feel will effect dyno numbers. Hopefully someone with more experience/knowledge can respond.I have always wondered if the rear end gears give different numbers.
