Cobra Jet vs. Boss IM Comparisons

[kdanner]

You guys need to quit looking at/asking for dyno numbers and start looking at on track results. We don't race dynos. 180 MPH for me, and plenty of you saw wbt run tens from the very first pass with the manifold on the car in August on a track most of you guys say is no good. Those are real world results of what that manifold can do.

You're above 6000 all the time huh? So, you shift your car as follows:

1-2 9000 RPM
2-3 8700 RPM
3-4 7700 RPM

Because that's the minimum RPM you're going to be making those shifts at to keep it above 6000. Either that or you're full of bullshit, again.

Again, the short bus forum, his BS isn't put up with anywhere else. Shaun is the guy who couldn't make his own car run better with a Boss intake. Why would anyone listen to him?

Jesus, he was say when your racing in the 1/4 or whatever that most of the time the car is above 6k rpm. Which is true. Look out we got a badass over here. Most dyno's show minimal gains with a boss in fact almost all. For a daily its pretty damn hard to beat the stock coyote IM. The difference even in the 1/4 is even minimal. Before you say "on the dyno who cares" Show me a bolt on car that made a significantly faster pass with the boss vs the Oem.

I understand. People dont like forum. Heck there alot of bs on this forum. All I was stating is what I read on the link. No reason to get butt hurt over stating something. I dont believe half of stuff I read on forum cause most time people are full of it. Now I dont think there is a big difference between the to intakes. But its also a drag intake. Boss is designed for road racing. Hence BOSS intake. So the cobra jet intake will be better than boss for drag racing.

Actually this forum is great compared to most.

I don't know how you have determined one is for road racing and the other is for drag racing when the runner length is identical, and the runner volume is nearly identical. Put CJ on a Boss302S/R and it will certainly lap quicker than it will with the Boss manifold. The Boss had some compromises made for factory assembly, it has plenty of firewall clearance so the assembly workers can install the engine from the bottom like every other Mustang. The CJ removes these compromises. It also removes the cost compromise of re-purposing the original GT throttle body.

I've owned the CJ manifold for 6 months, I had the Boss 302 engine before you could even buy a Boss 302 Mustang, I don't rely on someone else to do any of the work or even tuning, I have actual experience and real results, I'm not just making things up as I go based on what some wannabe tooner with a pack full of nutswingers on SVTP tells people. And BTW Shaun's power curves suck, look how they fall off above 6500. These cars can absolutely flatline from 6500 until the PCM quits, he's missing a bunch up top.

Yup I'm full of bullshit again. Fucking asshole maybe if you learn how to read correctly you might understand what I was saying.

This...the AED koolaid drunk on this site is unreal. Typical SVTPERFORMANCE homers.

For 1 most of use don't live at the track so we are looking for something easily tangible as a measure to go by if the investment in an expensive manifold is worth it or not.

2. Say all you want about dyno numbers yes, they don't equal a translation to track results but if you take a car already setup with a boss manifold rip that off on the same day with the same dyno in the same relative atmospheric conditions / temperatures and you see a consistent number difference with a new setup I think its pretty easy to say now you have some form of evidence to make a decision if it's worth it or not.

3. The Boss manifold has a consistent dyno proven history of the numbers falling hard under ~6500 rpms. That's been proven consistent on many comparisons on many dyno's on many cars. Obviously the results will vary but all are consistent with what to expect.

The guy on SVT Performance was essentially trying to show the comparison.

Unless your are making a serious amount of more power say like 30+ or more I think you can expect to see track results given you are a excellent consistent driver, which again most of us are not so its harder for us to use the track results as a medium for comparison.

I agree, you are 100% correct.

I understand your point to a degree. Yes a manifold will perform differently with the car not moving as opposed to being on a track with ambient air being forced to the induction system. However, a dyno, for the time being, is the best method of comparing the two parts.

Trying to compare that on a track is going to be unimaginably more difficult. I would say do this same dyno, then on the same day put the car with both intakes on an automatic(to reduce driver error) and see what happens.

+1! This guy understand the point of this thread.
