Cobra Jet vs. Boss IM Comparisons

[BLK2012GT]

Does it really matter if you lose or gain mid range power when you're racing you're above 6k rpms all the time?

If you read the whole thing shaun at aed says intake s are basically the same and believes the few extra hp come from the bigger throttle body and cai. I see this being true.the cobra jet tb is larger than our 80mm tb. Is it worth the money I personally dont think so. But drag racers want every little hp. I think its awesome intake but not worth the extra money

Very fair assessment. What size throttlebody is on the JC? I didn't notice. Guessing 120mm?

Id like to see results with a blower.

Ya i'd be interested to see how the CJ manifold stacks up against stock IM numbers and where it picks up power. The Boss manifold has shown time and again to lose power down range of 6500 rpms and only pick back up and add some from 6500+. Looks like the CJ manifold does the same with picking up more power at a lower power band but I'm interested where it will start making more power over the stock IM and how long / how much will it make over stock. Comparing it to just the boss IM isn't a great / full comparison to what can be had performance wise with the CJ manifold.

With that said I wonder if TS's Ported Boss Manifold can go toe to toe with a CJ manifold.

Couldn't we just compare the dyno chart with someone's dyno here of there bolt on dyno with a stock GT manifold? Plenty of people here have the same basic mods as the guy with the CJM.

Comparing 2 cars with similar mods isn't the best method. Using the same car, same day, same temps, same dyno, same atmospheric conditions would control the variations the best. I was just curious if TS essentially accomplished what the CJ IM did with a boss IM porting. Seems the CJ manifold and Boss manifold ported by TS find power sooner the same way.

Id bet gd money its identical to stock to boss swap with a lil more up top at a higher rpm. No thanks.

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.

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

I would agree with that if it were nothing more than a dedicated track car. I think most of us use them more as an all around street car. i like the twisty backroads as well as drag racing so the low to midrange matters to me. I personally dont think that a street car with no low/midrange is a lot of fun on the street. It really comes down to how the owner plans to use their car.

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

True but the "real racer guys who know everything about everything" says the only way to know what the improvements are is at the track so what's the point of the mid range gain or lost if you are racing it.
