When will Jeep

Or what modifications would allow my 6 cly Jeep to get 280 hp, 270 lb-ft, and >18 MPG?

Thanks

Brian Foster did pass the time by typing:

Your looking for a gain of 100hp and 50 ft.lbs Pick your poison of Stroked, blown, and intercooled with a 50 shot of nitrous.

However the >18 only applies in cruise and idle. :)

If your after a bit more power then go with a bored out throttle body, tuned exhaust headers, and a cat-back. Stay away from the TB spacers.

Well, I don't know my HP, but my mileage is at 23 highway and 1st will light up my 33" BFG muds way too easy, 2nd will top 52 mph or so turning

4400 rpm, 3rd pulls hard to 75 mph, 4th buries the speedometer and I have no freakin urge to find out how fast 5th goes.... It will climb sand pit walls in 3rd low, get too steep and it just digs holes, it won't stall....

I have been thinking on modifying it or the one I have sitting in the garage, but can't figure out why?

Brian Foster proclaimed:

That should be in the range of a transplant from the Crossfire SRT6, or if aftermarket is OK, a gift certificate from Hesco, Clifford, or JRE in your stocking.

Right after they become aerodynamic, which means they look like a Crossfire and are about as suitable for offroad.

Actually for the cost I would probably build a stroker first. Not that you can't stroke the 4.0 to 4.7 and keep the blower.

My biggest problem is they stopped selling 93 octane fuel in this area. There are only three stations and a couple of race-fuel vendors left. All they have is 91 and I have to mix for 92 to avoid pinging at full demand on the highway. (the price we pay for our toys)

The local hot-rodders have already zoned in on those stations and the local station I use told me he has have never sold so much fuel in all the days he's been operating and will probably be expanding the 93 to a second pump.

Keep in mind that supercharging increases lower end power. That's fine for getting on the highway or off-roading but not as good as turbos for passing. At any rate, a Jeep isn't a race car. More power just means you can get in trouble faster. :)

When was the last factory V-8 SWB Jeep?

I always heard "There's no replacement for displacement".

"There's no substitute for inches" is more general. :^)

Why? If it works do not break it.

I'm pretty sure the guy that sold me my XJ with the 4.0 said it was 377 hp and 1,650 lb-ft torque at 1200 rpm.

I tried that. 2 speeding tickets so far, that is definitely the down side :(

It's not the size of the weapon, It's the fury of the attack.
