HP Gains???

Hi guys. I am wondering what you have done to your 3.0s to get more low end HP. Im not worried about top end. I just want to be able to get on it when i need quick increase in my wheel speed, mainly for offroad. Im just curious if maybe a slightly, SLIGHTLY larger cam might be feasable, maybe roller rockers, or any other suggestions y'all have. So, shoot!

I hear you on that, a L/S with 4.10's would set me off perfectly!

intakes do not help (it has been proved with data) on a stock engine. ESPECIALLY on the low end where the OP wants help.

adjusting to a more powerful afr mixture, or advancing timing will make a difference.

the intake can be changed at the same time, but there is no benefit from that - your head does not breath enough to make the intake a restriction.

like I said, it has been proven with data that it makes no difference.

well you cant compete with actual data.

and ya i dont think exhaust helps that much, but def sounds waaayyy better. and it makes your truck faster because you always drive faster

Your talking about re-gearing. Trading top speed for acceleration. It won't affect engine power or engine torque but will make you accelerate faster. The negative side is you will have a lower top speed and cruise at higher RPM.

The cruise at a higher RPM is correct. Top speed is irrelevant. The speed limiter will kick in way before the rev limiter and more than likely before drag takes effect.

Your not reading it like I was thinking when I wrote it. top-speed (in each gear) will be affected. So before where you could go 50mph in 3rd, now you will only be able to go 45mph ( just a numerical example)

Basically you shrink the speeds that each gear can safety get too.

what exactly does replacing the 7.5 with the 8.8 do? how does it affect performance w/o taking gear differences into consideration?

the 8.8 is super strong far superior to the 7.5. it can take the abuse and heat better. From what Ive been reading and hearing its as close to a 9in rear as anyone can get. The 8.8 can be found just about on anything so they are abundant. it wont affect performance it is just stronger and will hold up better under stresses.
