First off.. the 1/4 mile will NOT LIE..

Ok, then lets be d1cks and say he only made about 340hp on a mustang dyno then. I understand that its the same tune, but most people get "dyno'd" on a dyno jet and therefore numbers normally are higher. Here is just a little video of my proving you guys wrong

hell without cams i made over 330whp/330lbs tq on buschurs dyno. I am told its a 23%/25% difference in power of a dynojet. that being said i would have made about 412+- whp on a dynojet. That does sound a little more realistic considering i did have traps to run 11's in the quarter mile in a full weight evo (12.1 @117mph)

What mods were on my car when i did them 1/4 mile runs.

Header back exhaust, intake, mbc, tune. (and a nice boost leak that nate found about a 3 days after my runs)



If you like, i will have nate print me out some graphs of his car, or have bryce bring them to the next meet.

If you are comparing these numbers to denny's numbers its an unfair comparison. Denny intentionally ask for a more drivable tune and did not want something extremely aggressive for his daily commutes. I am sure he can explain to you better what i mean..

 

LOL - The only thing worse than saying what your numbers would have been on another dyno is saying it for someone else - you know better than to start that **** in here. You think I'm gonna let you get away with that?

I was at 420hp & 450tq at Wyotech, and it went 12.0 @ 115 w/ a missed 3rd and a 1.9 60', and I think I was shifting at the wrong points...I still don't think the dynos are 10% off - I've been on both, tuned by the same person, and I've asked about mine and other cars that have been on both. It's not a matter of showing a video of dyno A and dyno B - it's a matter of being tuned on both specific dynos in question.

 

So you made 420/450 and ran a 12.0 @ 115. My question is how did i run a 12.1 @117 (2mph) just for arguments reasons, and only make 330whp/330 tq.

MPH are a true test really. More than ET's in my personal opinion. Just by going full throttle, you will reach a average MPH every time vs a time of 12.0 or 11.7 or 12.5... if that means anything I am about to ramble a who bunch so get on your **** kicker boots and get ready lol
there has to be a difference. I am just arguing that there is. Yes the car makes only so much power. But which dyno you put it on will tell you different things.

Cars that make it into mag's for car and drive motor trend etc etc all use a central dyno. The dynojet. Which kinda stinks, and they all do flywheel HP. which is even worse. thats what an evo makes 286 hp stock but on a mustang dyno makes if lucky a whole 206-215 whp. and 8's buschur has dyno'd under 200 whp (195-196)

Here is a little write up i have been reading over the past few weeks. as well as many others with calculations that show how it actually works. quite interesting.



I knew you wouldnt let me get out alive but ehre is some techincal data for the kids who can read in here



Chassis dynos use one of two basic means to test engines. One is inertial loading, where a large mass of known inertia is accelerated by the test vehicle. This is a simple, but somewhat limited method for testing. The other method, used by Dynapack, involves a load control mechanism that places an operator controlled load on the engine using electrical (eddy current) or hydraulic (fluid pressure) systems. The advantage of a load control type dyno is the ability to simulate a wider variety of real world situations on the dyno. Additionally, because operating conditions can be fixed, hp changes are far easier to measure.

The final difference between a Dynapack and virtually all other chassis dynos on the market today is that the Dynapack eliminates the tire to "road" interface. By using a special hub adaptor that replaces the wheel and tire, the Dynapack eliminates wheel slip, alignment losses, tire inflation/wear issues and more. However, by eliminating the large mass (and attendant inertia) of the wheel and tire combination, the Dynapack does tend to read higher than comparable "roller" dynos.


There are two primary differences between the Dynojet and the Dynapack. The first is very clear when you see them. The Dynapack requires removing the drive wheels and tires from the test vehicle. The second is that the load time (the time it takes to accelerate the test vehicle over a specific rpm range) is operator controlled (and fixed if so desired) on the Dynapack. On the Dynojet, load time is controlled by the amount of hp produced, and by the gear ratio chosen by the operator. We will address both of these in our calculations. (all calcs will be done in metric terms and we will convert to more commonly used hp and lbs-ft at the end)


This is why we recommend people use a rough percentage adjustment to estimate flywheel hp on the Dynojet versus a rough fixed adjustment on the Dynapack. In our experience, a manual transmission FWD car will lose 20-25 hp to the hubs on the Dynapack. A RWD car will lose 25-30 hp and an AWD car about 35-40 hp (the FWD case has been verified on an engine dyno). In contrast, losses on the Dynojet will be in the 12-14% range for FWD and 14-16% for RWD (opinions vary).

 

I have always like the older 5.0 mustangs. Hope you stick around, and make your rounds on the forum whenever you get time still...

I think all fathers/mothers make sacrifices at one point and time. I imagine i will do the same in teh future.. Just the perks of being a dad right? keep in touch.

Ps, stay away from the bmw's they are pretty looking.. thats about it.

 

You're trying to argue your Mustang numbers now...I was there the same day...we put down the same 315whp on the same tune by Al. You threw in some higher octane gas and upped the boost to get your 330. I fail to see the point there? FYI - My 315whp on Buschur's Mustang Al tune made 342whp on the Dynapack

I am arguing that Bryce's car will not produce 425/440 on Wyotech's Dynojet just because it made 400/400 on the Dynapack. My guess - he will be able to run high 11's...seems about right for those numbers on that dyno.

Also, your cut'n'paste backs your argument how?? It says right there "(opinions vary)" - so that's not exactly scientific proof.

 

I really dont see the point in any of the dispute .

Both of you already know that there is only one way to prove HP . Trap Speeds period.

I know of a specific car that has been between both the dynapack and mustang. And when you look at his power numbers from one to another and then back to the other. With even boost levels being the same nothing really added up. I am not going into the specifics of it on here but we can discuss sometime. As it is very odd to say the least.

Bottom line Dyno's are nothing but a tuning tool. So my suggestion is somebody gotta get bryce to the track and get him to put down some traps. That will tell the tale if his car got what it takes

 

This is my contribution of being a tool at this topic.

Last year my car makes 420whp and 337 lb.ft. mustang = 11.3-11.4 ish @ 122mph
Denny's Green powered Evo makes 420whp and 450 lb.ft. dynojet = 12.0@113mph.

So which one is correct dont know. All I know is I dont recall losing many races with the lesser TQ. and equal HP car!!!!

 

That was exactly my original point...I don't understand the reasoning of throwing out that his car would probably make 425/440 on the Dynojet. He made it sound like "OMG - it would have made so much more on a Dynojet" as if it meant something, and my point is that the car/tune are what they are no matter what dyno it's on or what number someone says.

Neither of those dynos are proven to be as accurate for proving out their track times as a Mustang anyway...they are exactly what you said - ways to get tuned.

 

I won't argue with either thing...

You won, and you're a tool

 

 

I am not here to argue. Lets all just meet at the track

 

What is this, an argument and I wasn't invited?

 

So.... when will your car be on the road and ready to go with the 35R?

 

Does anyone know where i could score a diagram of the EVAP system. I know it is under the driver side rear quarter panel. Ever since my car got hit, it is throwing a P0455 (large evap leak) when the gas tank is slightly above half full. I searched but didnt really have any luck finding anything....
