What would be the best way to increase horsepower in my jeep. I have ordered gibson exhaust, superchips programmer, airaid intake and throttle spacer. I have a 07 Rubi 4door lifted on 35s and 5.13s. What else would i need? Id like to get it up to 300 hp without any major changes.

 

300 hp without any major changes... [snicker]

 

You won't even see 300whp with a supercharger.

You bought the wrong vehicle to try to make fast.

 

No, but seriously!!! This has been the question every since the JK has been released...
All the items you list will help, but will not give you what you are looking for!
I have done everything on you're list and my jeep has improved, but I don't have 300 ponies!!!!!!
Do you're self a favor and sell the Airaid spacer! they are junk!!! and make a God awful whistling noise!!!!!
I took mine out and put on an AEM cold air intake and got better response and better gas mileage....

Yep, you can't get there from here without adding boost, be it N2O, Supercharger or Turbo. The only other way to do it would be to twist the motor at 7k or so and that would require a bunch of parts that simply aren't there and it's doubtful there is even a market for chasing after a mini van motor with the serious kind of parts your talking about that it would take to pull it off.

That said, I do think you can get into the 230 range at the flywheel with off the shelf parts. Intake, exhaust, programmer upgrades cover most of it and you can get most of the way there for less than $700. The only additional bolt on part would be headers and they are by far the least cost efficient and find their best use when third party coated for heat reduction. Still a ton of cash with minimal gains.

The only other item I can think of that would give you more power to the rear wheels would be an underdrive damper. Doesn't increase hp, but would decrease the amount that you are spinning accessories. I'm not aware of one that's out there, but I'm sure there is and it could potentially buy you an additional 6 or 7hp at the rear wheels.

 

I was searching for anything that can play with the electric stuff in the JK , such as racing coils or MSD, but unfortunately didn't find anything

but

I've read that HESCO is going to release a stroker for the JK in the near future .. we will wait and see

 

Hemi swap, that is the only way your gonna get that kinda H.P. That being said, a Hemi is a waste of $ IMO.
The $ you spend on a hemi could go to regearing, tires and all sorts of mods to make it one helluva Jeep. A jeep just doesn't need 300+ H.P. unless you plan on gutting it and making it a mud bog racer.
300 H.P., I don't think so, but with the right gearing selection to go with your tire size you should be pleased with the Jeeps performance.
Have a great day, I think I'll go have a beer now.

 

Ditto on the beer and x2 for gears. Best mod you can do for power to ground.

 

Yes, he should be fine with his JEEPS performance with the 5.13's and the tires. If he wants more Umpphhh on the trail, go lower than 5.13's.
It is a jeep, if he wants to boost his pleasure for raw H.P. then he needs to get something that gives you that feeling, say an old muscle car or even a new one.
I guess I'm different, I'm never in a hurry in my Jeep and it is geared for what I need (for now).
No offence was taken on your comment. He has just been givin' his options, now it is up to him to realize what he needs, a jeep with a hemi or supercharger? He may just need to have a Jeep that is capable of offroading and a car or truck that has the H.P. he needs to satisfy THAT craving.
