Need more power

[07suburban2500]

Hey guys,

I'm looking for recommendations on mods that will add more power to my truck. I'm sick of getting passed on the highway by teslas and the like.

I don't care at all about mpg, I'm averaging about 12mpg right now, 8mpg city and about 14mpg highway.

My main goal is to make the truck faster. I still need it to be reliable as most of my driving is on the highway on long trips, but outside of that I am game for anything.

Don't get me wrong, it has a ton of power now and it's fast for sure, but I want more.

Currently it has 6.0 with the 4l80e and 4.10 gears in the rear.

Any suggestions on where I should start?

Start with a good time from someone like Blackbear Performance @BlackBearPerf for the most bang for the buck. More HP, better throttle response and quicker shifting. That alone makes a big difference. After that the cost per HP goes up. Cam, long tube headers for middle of the road cost then heads or forced induction like a supercharger if you really feel like spending $$$.

Wanna race with Teslas? Why are you driving a big ol' truck? Sell it and get a smaller, lighter vehicle meant for speed.

If you want to make significantly more speed in your current vehicle, follow RocketMan's advice, which ain't cheap but is highly effective.

Define faster.

Top speed or off the line???

The 4:10 gears you have now are good for low end power to get you off the line faster but suck for top speed and fuel mileage on the highway.

A gear swap to a 3:73 or 3:42 would give you more top speed and fuel economy on the highway at the loss of some off the line.

3:08s would probably be to much in the other direction.

Magnacharger, long tubes, free flowing exhaust, less restrictive intake, mild camshaft and a tune to tied it all in together and she'll be a 600+ horsepower rocket. Maybe even a slightly higher stall converter too! Swap over to L96 injectors, not sure if the pumps are different.

With 600 RWHP and a race weight of 6,700 pounds, she'd run 12.70s @ 105 mph in the 1/4 mile.

sounds like a jet taking off.

Holy shit, that top video was pure sex

How would a setup like that do on a long road trip?

Right now from a stop if I really get on it the tires will roast until I let off!

On the freeway if I'm doing 70 and I step on it to pass someone, there is no lag and no drop in rpm, you just hear the engine get louder and it starts to Go!

It's a lot of fun to drive as it is right now and it's definitely fast and tons of power.

BUT...i still get left in the dust by all these cars on the highway and I don't like it!
