N/A Horsepower

Understood but they have similar characteristics so there's nothing to suggest the CJ would act much different. Again if you can get it to fit with the hood closed.

lower motor mounts is all that's needed. 3/4 of an inch. A new or modified cold air intake as well. I honestly don't see how it won't help given the heads flow much better so I see the manifold doing well.

Not exactly a weekend warrior job to lower the engine like a manifold swap is.

But again check the 3rd link I posted which is the AM test on the Boss manifold. Lost almost 23hp/23 ft lbs a the peak loss at 5300 RPM. It ONLY made gains above 6,000 RPM and let the 5.0 rev out more instead of dropping off power at 6700 RPM.

It wont make any usable hp for a daily driver other than on a dyno number on a piece of paper. Idk why people are so obsessed what paper says to spend that kind of money on the setup- $1500+lowering the motor, whatever that will cost.

There's no reason to believe the CJ will act much differently. They are similar manifolds with the CJ having more duration of the exhaust cam is all. The lift is essentially the same on the Boss, CJ and 2015 GT OEM.

Motor mount is a very easy quick job on this car.
You also must not know much about the boss as it's known to lose a lot of low end tq while the cj loses none. They are both made to gain up top and the cj gains all over. You can not compare them at all. Do some research before condemning something based off false comparisons.

Proper tuning makes a big difference here. Getting the cam timing perfect along with a/f and ignition can remove a lot of those low/midrange losses. It won't match the midrange of the stock intake exactly, but for a car that's going to see high RPM's the extra powerband makes it well worth it.

I've been DD'ing my Boss intake for a few years now and it's very exciting on the street.

Nice answer, I know everything and you know nothing. Really proved your point there.

Take a poll of how many people can lower a motor and you'll see 5-10 out of 1,000 on this forum. Whether I can do it is irrelevant, which I can.

Of course, but it looks like AM used Lund to tune it in their test and still had those issues with losses. Im not saying sacrificing mid range for high is a bad thing, but to the topic of the thread just to make a number on a dyno isn't the right way to build out a car.

The test showed that the stock manifold was 436.7hp at 6400RPM and with the Boss 440.72 at 7,400 RPM. Only a max gain of 4hp; but it definitely added to the curve in the upper RPM range.

Nice edit of your post so you don't continue to look like you don't know the subject. You are in the wrong post. The OP is asking about NA power , with a NA build comes making power all over including up high. If the OP wanted 600+ hp he wouldn't be asking about NA. Another thing to think about is who tuned that test boss, bama.... We can come back and continue this once the actual intake manifold in question is properly tested instead of assuming it's trash. Plenty of people with 11-14 have made incredible gains with it. It's the same engine just better breathing. The cj almost doubles the intake cfm.

I completely agree here, a friend got his cj on and tuned from rev auto the other day, it's downright Nasty and as his woman put it violent now.

It's your word against mine but all you have is an old test when the car was new and tuning wasn't perfected yet. Fact is the cj and boss aren't that similar in how they affect the powerband.

Where did you or I discuss you, your car, or money at all? You laid out a hypothetical setup ("would no doubt" is hypothetical) and VAGUELY MENTIONED A 2014 WHICH IS A DIFFERENT ENGINE HAVING NOTHING TO DO WITH THE LINKED AM TEST WHICH WAS A 2015 AND BOSS INTAKE.

Your post is right here:

Intake, headers,CJ and tune on e85 will no doubt be around 500 sae.
The 2014s with same mods are making 480s . We have better heads and cams to start so I see it being at or just under 500.

Are you hallucinating here about something that was allegedly said which wasn't?

I never said it was my money but you are saying it's not worth it. I've been in a cj manifold car on the street and it's got very usable power from low rpm to 7500 rpm. I'm trying to point that out. You say it's not street able but it is.

Guys, enough with the personal jabs. Stay on topic or you will be given a break from this thread.

2014 is not a dif engine in the sense that it's going to make less hp. So we can say that given that it should be better.

Again putting words in my mouth that were never said. Quote where I said streetable. I said USABLE hp in the power band in a non-race application; unless you drive around the side roads at 7,000 RPM regularly. Two totally different concepts.

No one said that. If the 2015 OEM manifold now made up 30-40-50-60-75%, whatever number, of the of the ground to the CJ/Boss on the old coyote vs stock, then is upgrading the manifold for 2 grand on the redesigned 2015 still worth it? That's the real question here. NOT what the 2014 did on the older Coyote.

 

[Blk2015GT]

Take a poll on this forum on how many people can tie their shoes and it'll be much lower than that.

Well of course. To suggest something so complex as lowering the motor on new mounts (maintaining all of the connecting and alignment with the trans and driveshaft is "so easy a caveman can do it" like it's changing a spare tire is simply mind boggling.
