Hey are those headers made for the 3.7L v6 as well... I mean obviously they'd be different but does that guy/company make them for the V6??

 

troymoto25, nice results!

 

I wish i hadn't seen those.

 

those look nice and clean...but yeah man uhm...its only 187 at the wheels? i mean stock don't we have like 186 at the wheels and like 230 at the crank?

 

Very nice results. I guess headers might become my next mod.

 

V6 or only V8???

 

Ok here is my engine mods and results. First my truck is an 05 club cab SLT 4x4 with the 4.7L V8 and 3.55 LSD rear.Average mpg 12.5 to 13mpg I do all city type driving and drive easy. All gas mileage numbers are hand calculated.
First mod was airaid intake kit. Noticed a littlebetter throttle response not much in the way of mpg increase.
Second was a Gibson Dual Sport exhaust system. Noticed a small increase in throttle response and not any mpg increase.
Third mod was a flex-a-lite black magic electric fan. This was the best mod so far. I noticed a good increase in throttle response and an increase in mpg. Averaged 15 to 15.4mpg.
The last mod was the Fastman 68.5mm throttle body. This really increased throttle response but my mpg dropped slightly to 14.2 mpg. Just today though I got 15.2 mpg.
So to sum up the best 2 mods for power increase is the electric fan and the throttle body. The fan showed the best mpg increase.
I may add a set of headers down the road and am wondering if Switching to 3.92 gears would help with the mpg. My goal is more power and better gas mileage.

 

Hey I don't remember does the Fastman TB add any Hp or just Tq... I remember hearing or reading that it only adds to Tq but I can't see how it would add to one and not the other...

 

from what the guy told me its supposed to add 10hp/10tq

 

So i read through this and saw some supercharger talk. Is there a blower for these trucks?? and it seems that there is now tuning options and cams.

Does anyone know if this will transition to the 08s?
