Jakee's 4.0 SOHC Build up discussion and motivation thread

[Jakee]

I figure headers will give you around 6HP min. In my opinion there worth it. Just not the biggest bang for the buck.

 

[Jakee]

I hope to top spindlecone's 210 N/A ST.

Don't get me wrong here, I'm not giving up, just a little more of a challenge than I anticipated.

No matter what trash I've talked in the past, spindle does have some high numbers for a bold-on type modded 4.0 SOHC. That's exactly why I picked him to gauge off. I'm trying to get caught up with you guys and it shouldn't be to much longer.

As it was told to me, you don't race a dyno. And my opinion is you don't need a dyno to tell you you're slow. I know ROUGHLY where I started from. .

While you may not be "racing the dyno", there is this little thing called "the scientific method". This requires proof: chasis dyno, engine dyno, road dyno, 1/4mile, 1/8th mole, 60', 0-60mph, data-logs, something! Of which you have some possible 0-60 runs.

My point being; if you don't know where you started (in the scientific method "ROUGHLY" translates to: "I have no clue"), how will you know what you have accomplished? Just trying to send you down the right path....

I WILL be keeping an eye on this thread, if there are no results, there is always the comedic value.

The more the marrier,My goal was to get OEM V8, 2 valve power, done that.
And jakee, headers on your engine will get you 3 H.P.
And don't forget, you guys are starting out with 205 crank, I started with 210

I have a goal, dyno'ing is not going to get me the goal. The mods have been proven over and over and over again. Do the same thing to replicate what they've done but do more. Change a few things (Using common sense only) for a better combination. Do you see my point? If all else fails, shove a leaf blower in your intake and dyno. Post the dyno and don't tell anyone what you did?

Roughly = plus or minus 5 HP for me.

Spindle - RPMoutlet.com Go to the 4.0 mustang section and look at the combinations once they add the headers. You'll see where I got 6 HP from.


Okay, once I get to the tuning stage then yes, a dyno would be a lot better than a stop watch. There WILL be some results.

After that I'm supercharging.

You may only get 3 or whatever HP stock (which I completely disagree with). When the engine is modded and you get maximum bolt ons available then I think you will definately see more than the 3 you state. MMFF has been steadily seeing around 10whp on the 05-06 Mustangs (v-6) with JBA headers. I also believe the point of peak hp is overly emphasized. OK you may see 3 peak hp only (for example) but what about through the entire rpm range? I will take 3 hp peak and 10whp average anyday over 15peak and none down in the usable rpm range.

I keep returning to this thread hopping to see some results/date; when is something going to happen?

 

[Fredness]

Do you see my point?

I can, but only because I know it's there. When you comb your hair that way, no one else will notice, I swear...

J/K

Seriously, I see what you are saying, but as I said, when you have to decide what is the best/worst mod, how will you know? I understand that $75 seems like a big drop in the bucket, but it's money well spent for a baseline! You are not only getting the REAL numbers that you are putting to the rollers (NOT the street), but you get to know your dyno operator, how they do things, how the set up works, what you need to prepare for next time and silly things like that.

That being said, I'll do like aldive and just keep checking in...

 

[Jakee]

I know my tuner and I know what he's capable of. The data is right in front of your eyes you just don't know it. hehehe

Sorry Aldive. I'm trying.

 

[Jakee]

Okay guys - Because SO many of you are just dying to see where I started from here's what I've did. I've called Houston performance. They've told me that I could come in, do the base line (To see where I started from) remove the old intake and put the custom mac setup on again and make a few more pulls. All this for the 75$. This time I'm for real. You guys want it so I'll give it. The week of OCT 2 is my plans.

Now the tread will have a baseline and the improvement DOCUMENTED for the custom MAC set-up. I hope that satisfies all you knuckle heads out there. (just kidding)

I still think this is ridiculous but hey. This site has given me some good advice so maybe this will help someone.

It will; it will help YOU.

I look foward to the data.

 

[JDraper]

Jakee, you will be amazed at how much you can learn from a good dyno session. I've probably got 60 pulls on my Mach over several sessions, and I learn more about the car and what makes it "GO" every time.

One of the big things you learn from a dyno session is what your A/F ratio is across the power band. If you start modifying your vehicle without knowing how the mods have affected your motor, you can easily blow the motor up. For example: Adding a CAI and a cat-back to many vehicles will alter the a/f to the point that the MAF can't compensate for it, and the vehicle will run lean, which leads to burned pistons and blown motors. During a dyno tune, you can add fuel to the fuel tables to compensate and bring the A/F ratio back in line.

 

[Jakee]

Just put the Gibson Cat back on. I like the way it sounds. Not to loud but has a nice rumble to it. I did some more 0-60 runs and now average around 7.8.

Rocket5979 - You might want to hurry up with your motor, i'm gaining on you. Just have around 5 more seconds to shave off.

Now I have to figure out how I'm gonna do a baseline?

 

[DOZIER]

Just to chime in here. JDraper got my brain turning. I have a Gibson Cat-back, and a Volant cold air intake. I told the guys at Hypnotic Illusions that I had that stuff when they ordered my SCT excalibrator 2. I also told Doug when I ordered it. I met him the week after I ordered it at a car show in Birmingham. So that means that they compensated with the running lean in the tune that I set up right? I don't have anything to worry about with my truck tuned with the SCT product do I? I don't want to "blow my engine up."

Jake, I don't know what your concerned with... Your truck is already faster than mine RIGHT NOW! I think I might be able to push it to about a 90 second ET.

You are fine. Not much of anything is changed in the tune after installing a CAI or exhaust. The MAS is meant to monitor and account for airflow. Whether that is high or low it still will be accounted for by the MAS. Even with a CAI increased airflow will still be metered by the stock MAS. After installing CAI and exhaust it is usually more of a precautionary measure to check A/F than anything else. Don't be worried.

I wouldn't worry with a tune that Doug made for you.

Good luck .....

Jakee, you should wait till after the baseline run to add performance goodies ( the cat back ).

Yeah - I got home and had a big box sitting on my steps. Guess I was like a kid in a candy store. The temptation just got to me. I drove it to work today to get more of a feel for it. I've noticed there's really no "Power band" anymore. It's pretty equal now and that's what I wanted. Before I'd step on the gas, the car would go and when hit a certain RPM would come alive. That's all gone now and thats good. Just have to learn again how to lunch this thing. I'm spinning again.

Anyways, I can work around it, i'm sure. Didn't take nothing to install and would be faster to go back the other way. I'll just be doing a lot of sweeting for a baseline and improvement dyno. I already know there's an improvment, just not exactly sure how much of a improvment.

You know, I agree with JAH when he said that average horsepower is better than peak. I want to make sure what I do does have a benifit on the street and not just on the dyno. Will find out soon.

Rocket - You'd still probably beat me.
