So...I'm done trying to find dyno results. I've come to the conclusion that either I suck at finding them, or they don't exist. Before I get to the question, let me state that I AM NOT planning on turbo'ing my ride. At least for now, if I end up with the money to blow in the future then yes. But as of now I cant afford that. I plan on doing N/A build completely.

Now onto the cams. Worth it? Gains? Does it eliminate VVT-I? (VVTI has something to do with the cam profiles itself, correct?) From what I've seen VVT-I is similar (NOT THE SAME) to vtec, except that fat cam profile is in effect all the time, and then at 3kRPM everything switches to that fat cam. This is off something from a toyota site. As far as I'm concerned I've seen a lot of bs go around about this, but this is my knowledge on VVT-I. IF. IF. IF im wrong, and someone is right. Please have a legit, knowledgeable answer on this. (And no, this isnt a VVT-I vs VTEC thread)

My concern is that VVT-I will now go away if I replace cams. I get the general idea of how vvt-i works but I dont know what will happen if I screw with the cams. So anyone with experience on replacing cams in there VVTI engine please help me out. I dont want to blow 500 something bucks on cams that I will not be happy with. I need to know the gains and what I will lose if I go through with this.

So to make it easy.

Cams. (N/A Cams)
Gains.
Dyno? Link to such charts?
VVT-I and how does it react to the cams
How is the pull with the cams.

Will I lose any gains?
What negatives will take place if I do this. (If any)

Thanks guy in advance!

PS... dont go in vtec. we all know how that bs works.

 

dezod might be the people to contact but they might be gone this week for sema

 

Did you call Brian crower and ask them about it?

 

jimmy john has them in their build thread.

 

I can ask. But what will they tell me? Like most manufacturers, I will expect a big number from them. This is why I haven't taken the time to do that. I'm surprised that no one has actually done a before/after dyno test of these cams. They have been out for some time now...I'll be extremely shocked if I'm the first to do so. :?

If anyone can let me know it be great. If no one can answer I guess I'll take the time to do this. Take my car, get it dynod. Put the cams in, get it dynod again. Meh. I will call BC and ask about how VVTI will work after install. I just can't trust any of these people. They WANT you to buy it. I trust people that aren't affiliated with these companies and give charts to back up their word.

Please...Anyone that has installed these? No one?

Don't forget to get a tune before you dyno the car with new cams!

Understandable to want to hear from someone who isn't trying to sell you something.

 

VVTI will work fine after install. Youll put the VVTI cam gear on the new cam. BTW, VVTI does not have a variable cam profile, it only modifies the cam angle (advance/retard). It helps with efficiency mainly. In fact, you could probably gain a bit by going to a static adjustable cam gear, than dialing in the cam advance on a dyno. (unfortunately I dont think anyone makes a adjustable cam gear for our car)

 

As already stated, you'd still have VVTI with the BC cams and VVTI only changes the intake cam timing, not exhaust. I'd expect roughly +5 whp/wtq from BC cams without any head work. Not exactly a big bang for the buck but that's what you get with a N/A build after you get past the basic IHE. Not worth it IMO unless you're a die-hard N/A builder and cost per hp doesn't matter to you.

 

You don't have money to go turbo and want power. Do you understand BC Cams are not at all cheap. And to add to it, you'd want to tune the car at the cost of a standalone AND a tuning session. If your main reason for cams is not spending money, you need to do more research. Even so, expect to gain 15-20 whp with cams and a tune, and at the price it's not really worth it. I know for a fact there are a few decent threads of n/a "builds" and BC cams. But once again, the big reason many don't run them is going turbo is cheaper, especially if you buy used.

Also, if you can't trust calling a vendor or maker, then how do you expect to trust the parts in the motor? I feel you are either not looking hard enough or want someone to make up your mind.

 

I completely understand his perspective about wanting input from someone OTHER than the person trying to sell him a product. He Isn't questioning the build quality, just the impact the parts will have from a performance aspect.


A 270 cam is fairly intense (this is their stage 2 Turbo/NA cam) for dd'ing. Either of their cams require upgraded springs/retainers which allow you to (suppsoedly) safely rev to 7k. I am not sure if there is any real performance benefit from this, as I haven't seen a dyno with these cams to see if they are still making power past 6500rpm.

IE:If I'm thinking about buying a new mustang, I won't go ask the dealer if they are great, I'll go ask the guys who bought them, and have been running them for a year or so.

 

Come on niece spicy that last comment wasn't necesary. He isn't disputing the quality of the product he is saying he don't want the manufacturer to tell him estimated power gains he wants to see real world power gains.

BC has done dynos of all their cams. People buy intakes and such because of Dyno's produced by the makers. Why should this be any different?

 

you're ignoring his point he has made. you came in here to state your opinion ignoring what he said. i know a forum is used to share knowlege but it is not your place to attack everyone's opinion you see. be a little more conservative in your statments and you will get on a lot fewer peoples nerves.

the man said for the most part he wants to see real world application not the numbers you see produce by the manufacture. if that was the go by my old injen cold air intake would of really given my tC 15hp like injen's dyno says it does.

also if you could provide BC's cam dyno that they have? i can't seem to find it on their site.

Paul has gotten 186WHP with a cam, I/H/E and the APRX1.

Sorry I dont have dynos to prove it. But Paul is a trusted source.

 

So you trust that an cai will increase hp and trq by 12? As well as exhaust? As the header claim 10-15ish. These guys say so...So my car must be at 190 then right? >.> please. i wish...BOLT ON 50 HP!!!!! hahahahaha. No, give me personal dyno charts...are you serious man?

I've done my research. so, no. They will most likely give me a big number. Ain't calling.

turb run around...4k-5k?

Ive dropped 500 in my car. I have cai (injen), exhaust(hks), header(DME). 1k after cams. got a tuner for free. can get dyno for free. so that cost is insignificant to me...

Im going to gut it tuned asap.

You tried a little to hard there.

But, thanks all for the feedback.

 

Also you need to think that the number provided to you are not whp gains but hp to the crank, So your set on us having 160WHP stock, no tc's stock have like 130ish whp, so if you think about making 300whp with a turbo and tune you have gain 170whp on a stock motor. Go f/i there is no point in sticking with n/a unless you wanna spend 10k or more, i got my turbo for 2k and it does its job, get the fact im running this on a tc with 106k miles on it and I have no problems. Save your money, i had i/h/e but looking back i regret not putting that towards a turbo honestly. Think about it, talk to people on here there not your enemies. Instead of telling them what you read or what you heard, take a moment and hear people out, the people telling you to go turbo know this from experience and people telling you an good n/a build will be double the cost of turbos ARE RIGHT. people have been on this forum since it started and have been through a lot more than you. I'm still newish on the forum and i learned everything from it form just reading, it brought me from a stock used tc to a boosted FUN daily driver. Im done now lol.

 

Keeame what "tuner" do you have?

 

not always true my dude. my old set up is up for sale for 1900.

 

Do it, and post some results up here. I would love to see what cams can do to an I/H/E 2azfe with a good tune.

 

That's roughly $3000 for 36whp. A used $3000 turbo kit will easily gain 100whp and most sell for less than that.

Since independent dyno testing has shown that IHE adds roughly 20whp that leaves 16whp for the cams and X1. So about $1000 in IHE costs $50 per whp. The cams and X1 (DIY tune) cost $2400 so that's $150 per whp.

Yikes! This is why I personally recommend to stop N/A builds at IHE. It starts costing a small fortune after that. Even a new $5000 turbo kit only costs $50 per whp for a very conservative 250whp net or $33 per whp for a realistic 300whp. You just can't beat da boost!
