New power numbers

[BigM460]

Well........
Very happy with the new numbers!!!
637.21rwhp and 538.59rwtq! That was with nothing on the supercharger.
Made 627whp with the air filter and pipe on it. Not bad! The suprise was the inlet I got hurt power. Only 611hp.

Fuel system ran very well too. Highest demand was 39 or 78%.

Good day! :banana:

[MOTOWN]

Sounds good! you need the elbow i have , and a bigger filter , i made the same numbers with the filter as without.

[justbob]

NICE!!!!!!!!

[martyo]

Nice numbers!!!

Jefff and I were discussing it this evening.

[chief455]

zoom-zoom! just adding headers and exhaust was the change?

Do tell? Have to admit that I am amazed at the power these things can make!

[BigM460]

Yep! 87whp and 46wtq gain! Amazing! :D

[BigM460]

NICE!!!!!!!!

Thank you!

[RacerX]

Very nice! Good to see my modded FPDMs working well! :D
(self serving pat on the back here)
Now if Marty would start getting these from me... ;)

No doubt! I'll give ya an atta boy pat on the back! ;)

Congrats! Great numbers. Did you also change your inlet pipe since the last dyno?

How was it driving this beast?

Never got on it on the trip home. 5 o'clock rush hour traffic. Think Jeff mainly safened it up, if that's a word.
Hero pulls were with nothing on the supercharger. Inlet tube and filter cost 10hp. I'm happy with that. Should be capable of making more power out on the road with moving air through the charge cooler also. Gotta say it really amazes me the power these things can make.. Love it!

Oh you can update your centi power thread for my car. :D

Damn! It's a shame I never re-dynoed after my S.W. treatment.. Curious now, oh well.

Keep those ears open for detonation.
Nice numbers

What new motor did you install/build?

Thank you! Thanks for the help on the pumps too.


What new motor did you install/build?

Same engine and all. Finally installed Stainless Works headers and made a 3" exhaust system.

Your close by if not real close to Mr. C Wright---no wonder he has been indicating the itch to get more power---now I think I know why...neighborhood is getting a bit to much power --LOL--carry on---anf BTW--Great Numbers!!!

He should be well into the mid to high 700hp range now. He's the one that talked me into buying the headers! He was off by only 7hp of what it made!:cool4: He said it should make 630hp. Lucky guess? IDK?
Thanks

Chris, what about a velocity stack? :D

How much boost and is that with a return less system?

Just didn't work. IDK. With it on, it's kinda close to the radiator. Maybe 2.5 inches. Maybe just not enough space, plus probably pulling hotter air more directly from the radiator.


[QUOTE=Mike M;1433102]How much boost and is that with a return less system?

18-20psi range. Yes returnless. 2 Aeromotive 340's, 2 of Bill's (racerx) fpdm's, and the Vortech fuel pump booster. Nice and safe amounts of fuel! :D So happy about that.

[sailsmen]

My IAT's were always higher at the Track than the Dyno.

Don't forget the air filter has a purpose.

Great HP numbers!

Now get some great track numbers.:)

[Jeronimojc]

Updated THE MARAUDER CENTRIFUGAL PULLEY /BOOST COMBO THREAD (http://www.mercurymarauder.net/forums/showthread.php?p=1398135#post1 398135) with your info.

Could you confirm your fuel system setup and RPM at max HP?

I imagine you did some driving this weekend. How does she run?

Thanks!

Fuel system is the same as stated earlier in this post. 2 Aeromotive 340's, 2 racerx fpdm's, Vortech bap. Max HP is at about 6300rpm.

Haven't gotten after it since retune. The belt started chirping and such, so I've ordered a new one. Didn't make much noise this morning headed to work though. Taking easy to make sure it's just the belt and not a pulley.

[Jeronimojc]

Were these numbers in a Mustang Dyno or a Dyno Jet? Just trying to get a feel for things. I hear there is a significant difference between the two.

Dyno Jet

[Jeronimojc]

Bummer. I was hoping to use your numbers before the header install as a good point of reference for what to expect, but the speed shop that will be tuning my MM has a Mustang dyno.

Do you know if timing was left the same during this last tuning session?

Looks to be the same. Keep in mind, I have a 03 cobra reman with just 8.5:1 compression. You have 10:1 don't you? Would think that would call for a significant difference in timing.

The great thing about a Mustang Dyno is they aim to please, just tell them what HP/TQ will please you and you will get it!

Nice numbers :bows:

Now go get a speeding ticket :D

If I may ask, what changes were made to yield the great hp and torque: engine rebuild, new engine?

Actually, I was wondering if adding headers permits more timing. My thought was that adding headers increases flow and reduces compression, but I don't really understand this stuff yet.

BTW, my engine is 9.6:1 CR

He added headers. He already had other work done, including a SC. See post #23 and clink the link.

I suppose the same can be said of any dyno. It all comes down to the character of the person running it.

The beauty of a Mustang Dyno is the operator can set it up to do anything, 1/4 mile run, etc.
It is also the downside, name a figure you want, 1,336TQ and like Sgt Mac u got it. Conversely.

DynoJet 240 there is nothing an operator can do except SAE or Standard.
The sole reason DynoJet was created was due to exaggerated claims by MC after market performance parts.

"Mustang Dynamometers are unique. All Mustang Dynamometers are loading dynamometers designed to duplicate real world operating conditions. Our patented control system uses eddy current power absorbers to load a vehicle exactly the way it would be loaded on the street...."

"Q:
We ran a test for my car at 3500lbs, which is the approximate weight of the vehicle with me in it + 1/2 a tank of gas. Should we have used the curb weight instead?


A:
The weight entered should equal the weight of the car as you wish it to be simulated, it's that simple. Curb weight is used only when there is absolutely no info on the car. In some cases you may want to add a driver weight, fuel, etc. to the curb weight for better accuracy. Its up to you."
http://www.mustangdyne.com/portable.htm



DynoJet
"This Model 224xLC can perform load tests including step, sweep and loaded roll-on. Closed loop load testing is also available by targeting engine RPM, speed or percentage of load. A simple click of the mouse or keyboard can turn the 224xlc from an eddy current dynamometer back into an inertia only dynamometer or vice versa. The torque cell calibration routine takes less than a minute to perform."
http://www.dynojet.com/automotive_dyno/default.aspx"

"Typically, people tend to look at a dyno numbers as they do an time slip from a race track. That's not what it does, here's a link to a primer on all the styles. It's got a lot of pages, but the real 411 is easy to extract.

http://www.mustangdyne.com/ChassisDy...ng-article.htm

I agree, the DynoJet is the accepted industry standard. It operates on measuring the movement of a 3400 pound drum, or roller if you will, and the computer does the rest. It's best feature is it's popularity. The machines are precisely built and carefully installed, with the latest in refinements in AFR measurment and user training. It's also available in a trailer mounted portable version for trucking to meets. Some might say if it's not a DynoJet, it's not a dyno. That's up to you.

I don't think it's the most accurate test available, but it's close enough for what you need to learn about your particular car. Like running the quarter mile, no car will produce duplicate figures in back to back pulls. But, the differences will be minor, I would suggest you do three pulls and average your numbers. Again, it's the machine of choice and I think because of it's reliability. As a diagnostic tool, a DynoJet in Dallas will give you the same 411 as one in Chicago. It is S.A.E. corrected.

The eddy current style is probably the oldest technology in use today, and is marketed by Mustang. Here is where I have to disagree with Warpath. My first dyno experience on the MM was a Mustang, and it reported 363 RWHP, and 1336.6 RWTQ (remember, that thre pulls averaged). Oh really...From just 4:10s and a chip? I cannot support the Mustang because of it's lack of S.A.E. correction and AFR data. It does not S.A.E. correct, and your 411 is useless.

Both the Mustang and DynoJet take measurements from rollers or drums, and IMHO, tires, suspension, and stretching tie down straps have a lot to do with skewing the facts. I prefer the DynaPack 5000 dyno, which is probably in the "water brake" style mentioned above, though in more "up to date" technology.

The DynaPack removes the question of tires, suspension and tie down stretch from the measuring by side-stepping these distractors. The DynaPack attaches directly to the powered axles, you can read up more here, and there are pics in the photo section.

http://www.grdperformance.com/dyno.aspx

I've had a dozen or more dynos on my first MM while building her, all of them on the Dynapack 5000 and it performed quite consistently. I was able to duplicate pulls and not have to average my data. In fact, I was able to come back the next day and get data within 1.0 of the day before. My max power came in at 275.4 RWHP and 301.6 RWTQ.

I had one more dyno test after this, on a DynoJet for my Team Ford power tune. Before the tune, my numbers dropped to 261.1 RWHP and 283.2 RWTQ. That a significant difference between the DynoJet and DynaPack and it serves to show what loss can occur from tires, suspension and tie-down straps. After my tune, the numbers came back to 271.7 RWHP and 293.7 RWTQ.

In light of how well my MM performed, I wasn't disappointed by lower numbers, they are just numbers. The real 411 is in the graphs and charts. At 1900 RPM into the pull, I was pushing 233 pounds of torque to the ground. By 2500 RPM, torque rose to 275 pounds. That is one azz kicking hole shot for a 4200 pound beast, eh?

That's what you need to know from a dyno test and why it's a great diagnostic tool, and not a high performance poker game.

Just my .02c, from my personal experience." SergntMac

I am sure you are right. It is relatively easy to manipulate numbers with a Mustang dyno. But I am pretty sure a Dynojet can also be manipulated. IMO it all comes down to whom you are dealing with.

Which is why we let the biggest character in our shop run the dyno! :P
