gth522 How much MPG did you lose?
02-19-2014 04:32 PM
PieFace you would also feel the extra power with the auto on the highway in passing or cruising.

and of course anytime you put it to the floor.

Its subtle under 3k rpm but its defiantly still there.

spinlock I love a big herd of thundering ponies under my hood as much as the next guy but I also love my 10A hood and I don't want to see bulges from pistons and valves poking through the hood when I unleash the fury of the herd. There are other vehicles much better suited than the JK of that.

According to the power curves published at the beginning of this thread the gains below 3000 rpm where most law abiding citizens usually operate are pretty mundane. Which means that if you have an auto the only practical situation where the extra ponies will show up is in passing situations in top gear unless you are in the habit of drag racing from from light to light. The few times I have come even close to redlining my Jeep off road was pulling out another Jeep that was stuck so that negates much value there.

I don't expect the instantaneous torque of an electric motor or even the low end of a diesel engine but I also would prefer not operate in the red zone of my tach. Setting spool up and whining noise aside, what am I missing here that has everyone so excited. Please enlighten me so I can be as excited and start saving my pennies for a purchase.


P.S. I like the lecture and animation on combustion engines but it is missing the forced air induction system which is the whole topic of this thread.

Put the SuperCharger on (UNTESTED) at about 10k miles.

RIPP my truck to develop the system map for manual trans jeeps. This means Dyno pass after Dyno pass as they played out every situation you could possibly be in on the road.

Then drove non stop cross country. There is no way your going to be harder on your truck.

Im at about 17k miles, I drive like a car thief, and there is no tick.

Yes I think for the most part if you are one of the unfortunate ones with the head issue it would have happened with or without this mod.

ADee1 Cool mod. Anyone concerned about bringing on the Pentastar tick with this mod in a quiet 2012 that hasn't displayed the problem? Just wondering a bit.

Here's my opinion, high end......in lower gear. Sounds crazy, I know, your brain thinks you want low end because its a jeep, but I was climbing nearly straight up in Moab, in first, 4lo, and where others goosed the throttle, I'd ease the rpm up and she would slowly crawl. Made it look easy.

Spots offroad where you think you need momentum, with the sc you don't. It continues to build power, just steadily climbing.

Goosing the throttle is all of our enemy. It's how thing break.

PieFace Hey all

I just coiled over at rock krawler. My sc is turning 37s now.

The power is still there. I'm considering gears, I've got stock 4.10s

UselessPickles When are you going to get your jeep back on a dyno so we can get a nice full torque curve starting from low RPMs showing the results of the latest tune?

Look at the RPMs. this is on 37 inch KM2s and 4.10 gearing. Ungodly fast.

I slowed down to take the picture.
and Rockin to Hair Nation awesome.

Testing lauching a car I put together from a shell. Built engine, plumbing, suspension, wiring, and some fabrication. Had a turbo in it in 1998 and made 430hp and 470tq to the tire then but it was a street car. In the video its making 730hp and about 900tq on a small shot of spray, to the tire. On a friend's car, I have installed 3 different superchargers in one day on a dyno session to see which made the most power. All vortecs, a XX trim, XXX trim and a Z trim. I if I remeber correctly the XXX made around 1100hp. That was about 12 years ago though. Carry on.

A meticulous discussion can lead increased understanding for those that care. Those that don't care about the details and don't care about increasing their knowledge/understanding are free skim over the details and abstain from trying to participate with unsubstantiated claims. The discussion degrades when someone tries to argue against the details without caring about reading/understanding the details, and with no interest in testing/improving their understanding/knowledge.

When the intake valve opens, and as the piston in that cylinder is traveling downward, it does indeed SUCK air into the cylinder. It's call VACUUM, and this happens on the INTAKE stroke. (#1 in below image)

The intake valve then closes. The piston travels upward on the COMPRESSION stroke (#2 in below image). The spark plug fires, shoving the piston down with immense force. The air/fuel mixter ignites, quite literally exploding. This is the POWER stroke created by an internal combustion engine and it's where all our awesome torque and horsepower are made (#3 in below image).

The piston then begins moving upward, the exhaust valve opens, and all the spent gas is pushed out to the header, completing the EXHAUST stroke (#4 in below image). As the piston reaches near top dead center and begins to pass on to the next down stroke, the intake valve opens again and the cycle repeats.

These four "strokes" are why this type of engine is called a four-stroke.



So for you to say that there's no "sucking" (which directly implies that no vacuum is created) is horribly incorrect.

And YES, adding boost to an engine makes it do less work, so long as the components can withstand the additional power being created.

Don't believe it?

Try inhaling through a straw. Then put an airhose in your mouth and push the button. Which one took less work for your lungs to inflate? Sure, this is an oversimplification, but if this doesn't help you understand the concept, nothing will.

And to say that a turbocharger puts less stress on an engine? I'd love to hear your rationale behind that. The exhaust drives the turbine in a turbo, so the engine is having to work harder to push the exhaust out because instead of free-flowing into a pipe (the headers), it how has to shove the exhaust past the equivalent of fan blades.

A supercharger is belt-driven, just like an alternator, a/c, or any other power-based accessory. There is parasitic loss as it does consume a few horsepower to actually spin the pulley on the supercharger, but to say it's tougher on an engine? Bollocks.

Please know what you're talking about before acting like you're an engine expert.

I'm not one either, but I did stay at a Holiday Inn Express once upon a time.
I don't feel like reading all that, but I know this. Even if I disagreed, I would never get into an argument with someone serious enough to post a GIF.
