Cobra Jet vs. Boss IM Comparisons

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.

Haha, very true.

In my opinion, what an owner needs to do is sit back and think about the end goal of what they want from their car and how they will use it primarily. Everyone has a different idea what they want from their car from being a monster at the track, from a roll on the high way, autocross or just a fun all around street car. I think what a lot of owners seem to forget is that when you typically mod a car to be strong in one area you are giving something up in another. But as long as the owner is happy with it is what matters.

Myself, I'd like an all around strong performing street car that is fun as hell to drive. Strong power, good handling for my country backroad driving that I do love so much and some occasional drag racing/pull with friends. I know that focusing on the handling more I will have to sacrifice some of the launching ability of my car and I'm okay with that. My days of spending every weekend at the track chasing magical ET numbers are over for me. While it will never be the fastest track car here, it will certainly be very fun to drive.

Exactly. I've had my days at the track 10 years ago when I lived there every weekend. I could careless now. Sure i'll go every now and then but I'm not going to try to break records and shit. Hence why I haven't bought another set of wheels and slicks. My car is a fast fun street car and that's what I wanted.

You're arguing against kdanner and wbt... And excuse my complete assholeness but its coming from you who completely shit talked about how fast your NA s197 is/would be. I'd bet as much as you want that kdanner or wbt stock would destroy you. So I take what they say or BruceH and learn from it.

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

I am using a stock GT500 TB which probably has less surface area than the stock 80mm unit. Shaun is just guessing.

IMO the gains over the Boss come from a more efficient upper plenum design specifically where it meets with the runners.

So how much HP did your car make on a dyno and what times did it run at the track on the same night I ran my car?

It already happened. See above.

We are sharing our experience with you guys and I think we have proven what works and what doesn't. Both of us have had 3+ years of experience at the track with these cars and spent a lot of time and money developing our combinations. We both have spent much longer than that doing this sport. We don't know everything and I have yet to meet anyone who does. It's a constant learning curve.

I understand what we do doesn't apply to everyone's needs and there are some who will disagree or want to argue. If some of you want to spend money on stuff that doesn't work that's fine. If some of you want to use dyno numbers as gospel that is fine. I think Jeff's car is a perfect example where it put down good numbers on a dyno but can't get down the track. He built the house before the foundation and now he is stuck trying to figure out how to put a foundation under it.

For those wondering about comparing results between the stock intake and Boss intake. Similar conditions, different days at the track, same mods minus the intake change.

Stock intake:


Boss intake:


Like I posted in the sticky, there are gains to be had using the Boss intake. It doesn't really make more peak HP vs. the stock intake however from ~6,800 to 7,700+ it makes the same power (unless you are using an AED tune). The advantage to this when drag racing is you are making peak power longer resulting in better times.

The CJ intake has a similar power curve as the Boss but is a more efficient design which results in more TQ/HP. Is it worth spending ~$1K for the needed parts vs. ~$450 for the Boss? As mentioned, it depends on your goals.

So the thread has now come full circle. We saw this on the dyno charts. So what was all the back and forth banter for lol?

I want to have a fun car to drive and I have it. And I'm not arguing with anyone. I really haven't read shit what they've said in this post except for when he said I was full of bullshit about what I said which what I said is true. At the track who cares about midrange gains when you are at 6k or above the whole time you're racing.

With you on the bottle maybe. I am not a street racer but a couple of months ago I offered to meet you and line up at Ennis. I showed, ran 10's, and you never bothered to introduce yourself and take that offer up. The way I see it is you spent a lot of money on an 11 sec. car. History isn't on your side when making claims.

Like I mentioned in this post:

....I need more data before saying it is worth spending the extra $1K on a CJ setup. I'll update the sticky as we capture more info. Someone else's dyno numbers don't provide me the data I need.

There's no point of arguing with you about your car and my car on the streets. One you know everything and anything about these coyotes (ok) and two you don't street race. Prime example my car is faster then what it appears at the track, I race a person in this group and we ran the same time and mph at the track. But we did a 30 roll starting in 2nd gear in mexico and I walked him like he was standing still. It wasn't even a close race. But I expected that since I make 100 rwhp then he does. So if we did ever race on the streets I don't think your car has a chance against mine. Sorry that's my opinion so take it with a grain of salt.

Maybe to you. Maybe to other people they have already decided it is or isn't worth it just based on this. Assigning a dollar value to horsepower is on an individual and case-by-case scenario. So even when you draw your own conclusion, other people might not feel the same as you.

That's fine and I respect that. But as you already stated, the CJ makes more power than the Boss. I really don't understand what the problem is here lol.

Here's the thing. They live at the track and only care about what happens at the track. I really could careless what my car does. I always wanted a black/black 6 spd 500 rwhp NA and big shot of nitrous. Guess what i have it. And I highly doubt their bolt on car would beat my car on the hwy.

That's a damn gd post. I don't live my life a qtr at a time. I'm not chasing a magic time slip.
