brenspeed posted a dyno in their cam thread, there's some good info in there to give you an idea of the gains you can expect. I'm planning on cams when I build my motor, mainly for the cool sound I'll be doing all the labor myself, save some money.

the $1,600 that jwharton mentioned is actually pretty good if you ask me. figure with intake and a tune they're saying about 40whp gains. that's WAY more hp for the money than long tubes and exhaust which everyone does for relatively small gains. figure $1,600 for 40whp is $40 per horsepower. my Kenne Bell kit works out to $31.50 per horsepower so the cams are the probably the best bang for your buck in terms of HP per dollar without going boost.

 

I can only dream of such power!

 

Wait wait wait... 40whp gain WITH the intake and tune turns out to be only about 10whp from the cams alone correct?
Say you already have CAI and a tune...
Why spend so much money on cams then if they only get ya 10hp?
Or is it saying it adds an additional 40whp on top of what you have with an intake and tune?

 

So you are giving a CAI/Tune only a 15hp gain max?
I find that on the LOW side don't you?

 

Before I had long tubes (only a CAI and tune) I put down 291 rwhp and 304 rwtq on a Dynojet. After headers, cams, delete plates, and UDPs I hope to be at around 350 rwhp and 350 rwtq.

Here's how my cost breakdown goes:

Parts:

Cams & Limiters: $650 (used from Boozshey) normally $844 from Brenspeed (cams - $659, limiters - $185)
Under Drive Pulleys - $200
CMCV Delete Plates - $150
Valve Covers - $250

Total Parts: $1,250 (used) / $1,444 (new)

Install:

Cams: $600
CMCV delete plates: $80 (I know I could do this myself, but I don't wanna bother since they are tearing into the engine anyways, let them have at it)
Under Drive Pulleys: Free (since pulleys have to come off anyway)

Total Install: $680

Total Parts, Install, and Dyno: $1,250+$680+$300 = $2,230

Take out cam covers and under drive pulleys and the cost comes to $1,780.

Given the amount of swing that people pay for other mods (rear end gears come to my mind), $180 is not that big of a difference. Granted, he will get a guest house, but I'll be in my own comfy bed!

Oddysey, your's may be faster, but mine will sound meaner!!!

 

Take a look at this article. It's about everything you need to know about CAIs.

http://www.mustang50magazine.com/tec...ons/index.html

Stock: 261 rwhp, 282 rwtq
JLT intake/tune: 288.9 rwhp, 303.5 rwtq (+27.9 rwhp/+21.5 rwtq)

My CAI/tune is 291 rwhp, 304 rwtq so my gains were ~27-29 rwhp, ~20-22 rwtq

I'm hope for 350 rwhp, 350 rwtq which would mean +60 rwhp, +50 rwtq.

I don't think that those numbers are too unreasonable, but I won't be heartbroken if it comes out to be less than that.

 

What I am trying to get to is this.

I have a CAI/tune 91oct from Brenspeed.

I was wondering if I added cams alone how much hp gain am I looking at
on TOP of the CAI/tune I have now? (meaning hp not added together)

 

You are correct That is why a built 4.6 or 5.4 isn't off my radar

Blacksmoke - I put down v6 increase numbers, GT are 5-10 more HP gain, so like Jasper said, around 20ish.

 

I'd call Brenspeed and ask them. since nobody has these cams yet nobody will be able to answer your question

 

there's a little problem with your math there friend

288.9whp - 271whp = 17.9whp gain
303.5trq - 289trq = 14.5trq gain

still a good gain for just an intake and tune but not quite 28hp

I'd be curious one day to see someone dyno the intake alone, then the intake with the tune. then we could see what power is gained with the intake vs intake and tune. it wouldn't be that hard to do, just install the intake, dyno the car, then load the tune and dyno it again
