You do know im not talking about a 2j I have 7mgte

 

 

I agree with most of what you say here (and said after), but there are lots of times where you want more power but not more throttle. Sometimes you need to get a little extra juice to get up over a rock (most of my reference in this is for rock crawling, FYI) but you dont want to be building power because you dont want to fly over once you get to the top. With an SC at part throttle you can build boost and power pretty easily without giving a lot more gas and inch your way up, and its linear power unlike a turbo (roots blower, not centrifugal) so you know exactly what youre going to get. In a turbo, unless you have it tuned very specifically to your needs, a little more gas can build boost quickly and give you more juice than you want. Theres not going to ever be agreement, just my 0.02

 

With all your turbo school I would think you could understand how all the blow off valves and wastegates, along with the necessary piping wouldnt make for the most ideal off-road rig. having rocks, mud and dirt kicking it sure to get in some places it shouldnt! ANd like Lolzabee said, the turbo needs to spool up, where as a blower is always making boost, even a centri will have a few lbs above idle. You could run a S/C setup with a recirculating bypass valve. I think some PD blower have internal bypasses?

When your offroad your rolling pretty slow with very lil RPMS, and when you need power half the time its already after you get stuck! You need it now and need it steady so you can creep over the obstacle.

 

Yep. I know your not talking about the much better 2jz-gte motor.

When your all rock crawling, you in 4hi or 4low?

Should be 4 low. And I know you aren't really just idling over rocks.

With the right wastegate and EBC you can have a setup that is at full boost by 1100 rpm. And it will keep it at your desired boost level on a very linear scale. Just get a big enough wastegate to not bottleneck flow. That'll prevent any sudden surge of power causing loss of control.

 

So, say your at a point in the trail where you need more power. So with the EBC you bump up the boost a bit. You got the power.

Need less in the next section? Drop the psi a tad.

If you want that kind of versatility from a s'charger you'll be swappin pullys all day.

 

If you're at full boost by 1100 rpm and part throttle you're going to be completely off the compressor map by 2000 rpm...

It's very simple, you CAN do it with a turbo, but it will be much easier with a blower. Less piping, less tuning, less hassle in general. I won't argue that turbos don't belong on jeeps or trucks, cause it's not true, but they don't belong for MY application.

 

I agree. A turbo making full boost at 1100 rpm with part throttle isn't going to be dry beneficial. I was using it as an example, more aiming at the fact that you can have a setup to spool at~ 500 rpm above idle.

To be honest id rather it hit at 1500-1800, but im doing this for an auto, so my outlook my differ from yours.

Anyway, using a dual wastegate setup it wont matter how.soon the Turbo hits. You can reach your desired boost level, then stay at that exact boost level til redline. Why? Because the EBC tells the wastegate that you've got all the boost needed, so no more. You'll stay right at your desired boost level, no compressor overrun, aka boost creep.

Im not saying this is right for everyone. Im just saying a turbo is more versatile than any s'charger, and certainly more versatile than anyone here gives them credit for.

 

I agree with everyone everyone knows there's a way to run everything on everything just some are easier than other

 

And more versatile.

Oh, and some allow for better gas mileage. Unlike the s'charger.

But this isn't a turbo vs. S'charger thread.

 

My eye ***** hurt

 

>implying the 4.0 needs any more power than it has unless your racing.

 

the 4.0 has pretty low power, dont kid yourself. 3.0L nissan engines (the NA engines obviously, not turbo) made the same HP and only 20 ft. lbs less in 1996 than the 1996 jeep 4.0. Its an archaic engine design that doesnt do much for maximizing power. Pushrod engine, etc. blah blah. Basically, the engine in my 2002 maxima makes 15 more FT lbs and 63 more HP at the wheels than my jeep makes at the crank. And before you ask, yes it does make more tq than my jeep at 2k RPM...at the wheels

I love my jeep, but efficiency of this engine is lacking. It lasts a long time though! Though not as long as most import engines of its time do

/americancarcompaniesrodeagoodthingwaytoolong rant

 

Yeah...welll...beat the Jeep 4.0s reliability!!!

But seriously, it goes get the job done.

 

Let me see your Maxima towing 5,000 lbs.
