This is not very interesting because most of it is marketing hype and is highly speculative and opinionated.

If you need a JK to go fast in a straight line, my sister, Prudence, said that you also need to be able to pull close to 1g on the skid pad and stop it quickly as well.

Her answer is to forget the engine hang on's, rebuilds and swaps. Just get a '92 RT/10, pull the body and interior, and hang the appropriate JK stuff in their place.

The reason for mating up the JK with the RT/10 is that they have just about the same wheelbase. You may need to do some custom fab work to make it street legal but it will put an end to who can come up with the most ridiculous dyno printouts.

And, as Prudence says, "Be safe". Don't make it go if you can't make it stop (and corner as well).

I just pop a cap into the tire of anyone trying to race me, then it doesn't matter what they are driving or how fast they can go....

I just got back from the future after installing a K&N in my JK. What did I miss?

3.8L engine

First thing is, the results of all the mod's you did sure sound "too good to be true" if they were attainable. If those were in fact true, everybody and their brother would be buying and praising the lord for all those hp and torque gains claimed. Now with that being said, we are talking about a Jeep, here, which I don't know about you guy's but my speedo only says 100mph, which I personnally don't belive I'll ever come close to hitting. I bought my 2011 Rubicon not to go fast, but to go anywhere I damm well please. Everyone I've know that has owned a Jeep has always told me that "There not going to get there first, and they might get there last, but you can rest assured that they well get there"

I myself have installed a K&N CAI, which will definetly help the engine breath better,but thats about it. I still wish that it would go faster but its not and thats that. The only way to increase the HP and Torque is to go out and buy you a Hemi V8 and install it, then you will have enough power to blow most of everyone's Jeeps doors off in this forum.

Dyno results?

If this wasn't put on a dyno at a local shop and tested before and after each mod was added how did you determine you gained 27hp?

This is a serious question and not meant to annoy. What other way is there to determine that you truly had any gains in HP and torque?

I'll chime in to support the OP.
I put a Unichip piggyback, cold air intake and dynomax catback exhaust system in my JK recently and it really does make a considerable difference in power.

Even in Economy mode on 87 octane it pulls harder in every gear. With 92 octane on "sport" mode it feels like a different motor and it's easy to over rev as the RPM's come up too fast to shift at WOT. Actual HP gains? No idea but it is obvious behind the wheel. Accelerating to pass in 6th gear on the highway is something I've never experienced.

That said I'm taking it all out and going back to stock. I'll just sell the intake, exhaust and chip togetehr in hopes of recovering some of my investment.

For me personally the HP gains don't outweigh the exhaust drone and intake howl. Some might like thier Jeep to sound low and loud, I don't. It was an experiment, it works as claimed but not my style. I have a loud as hell 71 Z28 already.
I Stock power with 4:10 gears is good enough for me. I've always liked how quiet the Jk is, especially with the top off.

Heh Heh, just regearit to the proper differential ratio and thats it-

Expensive though, but if you complain about throttle response/power/mileage-and you won't do a regear, or buy a new one--

Sell the jeep !
