Re: 300 NA horse power a myth?

I looked into cams for my 2v they claim around 30 hp with stock heads. Not sure what numbers a 2v would get ported and polished heads. These cams also needed valve spring and retainer upgrades. I don't even think the advertised 30 hp is rwhp if that's the case I'd be looking at 25 rwhp give or take.

No **** *******, of course it has ported heads. Did you think he wanted to get there with untouched heads? Now who's the dumb****?

You seriously want a dyno sheet, so actual track times and mph doesn't do it for you, ok.

Oh and the 83 hp, that was 298 on a dynojet and 381 on a mustang dyno, so dyno for dyno it's easy to say it was more than 83 hp gain.

How about a track vid showing 115 MPH?

I'll see if powerhouse has the sheets

The key to remember it is about component matching.
Dynos are nice to dial in a tune but they don't tell the whole story. Whether you ever get to a track or not you won't be happy with your street car is you have too much cam, or too much exhaust, yes, you can have too much exhaust. What about your final drive ratio? What about your converter? Your ignition, does your intake match the cams?

Don't just buy parts and put them expecting the advertised gains. Do your homework before you spend another dime.

The first question you need to ask yourself is, what do I want out of this car?

Once you have an honest answer to your own question you will be much happier.

Youre officially the dumbass. The op said 300hp without going with a power adder or going into the engine. porting the heads consists of tearing into the engine. Way to read you dumbass. So you can go ahead and apologize now that youre agreeing with me on that one.


I dont care about times. I want to see a before and after with just the head and cam swap. Youre one dumbass noob. And so now youre claiming a 90+rwhp gain with just the heads and cams, since the mustang dyno reads lower than a dynojet

This was the original question. Learn to read before you talk ****.

You don't care about times, really? You would rather a dyno sheet than actual results. And I'm the noob, LOL

Im not gonna talk crap anymore as it is just a waste of time. I agreed with the op and you didnt pay attention to the original post. So that argument was for nothing and you should apologize.

Back to youre situation. Did you up the boost after the heads and cams? I can understand then. But not if it was just a simple swap.

Re: 300 NA horse power a myth?

The first Dyno is with just a canned Diablo tune 197
The second (Excessive sheet) is after I took off the Procharger and had the car tuned for N/A 269 (I know, I said 270, oops)

Now since I don't currently have a Powerhouse Dyno sheet you'll have to use your imagination - if I got 72 HP N/A it shouldn't be a strech even for a rocket scientist like you to see gaining 83 HP woth a blower. The blower of course takes advantage of the freer breathing heads, in case you didn't know.

Now I want to take a moment to apologize to the OP for jacking his thread. I usually don't engage in these kinds of pissing contests, but I am sick of people that don't know what they are talking about spreading misinformation. Good luck on whatever you decide to do with your car.

Re: 300 NA horse power a myth?

I ran a 13.64 @ 101 with a ground pounding 246 rwhp.

Actually, that confirms what I said, 13.64 @ 99 in a heavier equals more power.

Re: 300 NA horse power a myth?

So all you had was a crappy tune and dual exhaust on the first graph. on the second graph was with the heads and cams correct? did you have stock cai, pulley, manifolds, and mid-pipe still?

Re: 300 NA horse power a myth?

I put my car on the scale and came up with 3485 lbs. I also have 4:10's with a 1.8 60ft.
Should I remove my spare tire and jack? Or does that little weight matter?

Well every bit matters. Im not sure how much the spare tire and jack weigh. But I believe its a tenth for every 100pounds or so. You could also look at removing your back seat. All of those together add up to a good amount.

Re: 300 NA horse power a myth?

13.81, 2005 4.0 auto, 3526lbs, at the buckeye brawl 2 in Norwalk Ohio, bolt ons only, currently running 12.62 with a vortech and a best of 11.76 with 12psi and 100 shot.

No dyno tuning at all. Ever. Currently I use emailed tunes from VMP with no data logging.

the 3.8 six may not be able to do it, but the 4.0 can.

Dyno tuning can get the best out of what you have, but if you have the wrong combination what difference does it make?

ranebowsixx claims are correct, seen it, watched the various builds and I gotta say he is not the noob. We may have low posts, but this is not the only forum on the net.

You could achieve your goal, it would take a lot of hard work and money.
I had the goal of running 13's n/a using bold ons only, it took me 2 years, but I did it on pump gas.

Im not arguing times here. The only thing I disagreed with is an 83rwhp gain from heads and cams alone. At any rate, I really dont care about arguing over v6 mustangs anymore so good luck to you and that motor lasting much longer.
