Talking More Power??

Hey guys just wanted to know of a good way to get a little more power. Since I put the lift on I have been runing a little slugish, so i just want to make it a little smoother..Thanks again guys

More Power:

K & N cold air intake: $300 and can be installed in about 2 hours. adds a HUGE amount of power...totally noticable- louder and better gas mileage.

performance exhuast: pretty much needed for the K & N and getting just a performance exhuast helps a little bit.


These are my two favorite ways just to pimp out a ride for more power with the most bang for your buck!


By the Way, I checked out your photobucket pictures...is your jeep a black sahara? If so what year? i have some questions for you if it is. I love how the new lift and tires look and want to see what you have!

waste of money. regear your axles to get the power back

The two words that you use "slugish and smoother" has me wondering something totally different from the previous answers to your original post.If you added different tires along with your lift then maybe it feels slower and that would be correct. Regearing will fix that.

x2

regearing is the way to go.
don´t waste money on things like intakes. installing a "this sticker adds 50 HP" sticker is way cheaper and the practical effect is the same.

IMO 35s are too big for a 4cyl. the highest possible gears (4.88) are too low for that.
did you enforce your axles for the 35s? or do you want to wait until they´re damaged until you install some stronger ones?

then you may want to look into a super 35 if you don't want to deal with fitting a 8.8. You will end up with a locker too with the super 35. If you want you could also truss the d35.

why is cold air intake and performance exhaust a waste of time? I was thinking of doing just that until I read some you think it is a waste?

Unless you get results from a certified - dyno run (by a 3rd party), then I'd believe it. You'll get some improvement (minimal) in throttle response but hp gains... no going to happen.

So if I am planning on pulling a trailer (5,000 pds, occasionally) would you suggest gearing or something else?

Jrzymilitial, your power loss caused by installing those 35" tires is NOT going to be fixed or even improved in the least by an aftermarket air intake system. The only way to fix that, really, is by regearing your axles to a ratio that raises the engine RPMs back up to where they were originally. Actually the RPMs need to be just a tad higher than originally to truly compensate for everything your bigger tires and suspension lift has done to reduce your engine's performance.

The engine has a harder time turning the 35" tires because they are heavier, have more rolling resistance, and they have substantially more leverage against your drivetrain due to their bigger diameter. Like using a 6" lever against something, then using a 12" lever against that same object... the bigger tire has more leverage against the engine. Not only that, but the taller tires and taller suspension lift makes the Jeep sit up higher in the windstream for more wind resistance... and with bigger tires meaning your engine is turning over at lower RPMs at the same speeds, it's not putting out the same HP at the same speeds either.

The only way to effectively restore your lost power is to regear both of your axles. If your transmission is a 5-speed, regearing to 4.88 will do the trick. That's also what I regeared to for my 5-speed and 35" tires and the power was back... like magic. It's about a $1200 job but that will actually do something, whereas spending $300 for some aftermarket air intake won't do anything but transfer $300 out of your wallet.

And just so everyone knows, those aftermarket air intakes...at BEST... only produce mild gains at wide-open-throttle and at near redline engine RPMs. The TJ's air intake was actually designed to be very non-restrictive so you won't see the gains with an aftermarket air intake system like you will with some high-performance cars that have restrictive air intakes that were actually designed to be restrictive... like the Mustang 5.0L and Camaro Z-28.

And Tray, what are you going to be pulling that 5,000 lb. trailer with? At most, a Jeep Wrangler is only rated to tow 2,000 lbs.

I would suggest a bigger truck. Like Jerry said 5000lb is way too much for a Wrangler.

I'm not big on intakes or exhaust except for some cool noise, however JP did test a wide variety of intakes and dynoed each one with some shocking results. All the power came in the top end, but then again that's exactly what us 4 banger owners need. It'll rocket from a stop on flat grade, but get it on the highway and it doesn't have anything.

I'll see if I can dig up the article.
