The shop where I take my cars and such wanted to get a basline dyno on my Evo while it was still stock... so they said they'd do it for free. Why the hell not, eh?

Here is the Mustang graph. Not too bad. The torque is definetly there; I am pretty happy with that. But the car is choked in the higher rmps: boost falls from ~ 22lbs to 19lbs and the intake/ exhaust just don't breathe well enough.

I am pretty happy with the stock numbers, though

 

Great job, great idea, and great luck on getting a free baseline dyno. The good thing is that now you know their MD reads like a Dynojet from the beginning, so there won't be any crazy arguments after later dynos when modded. You actually put down more torque on that MD than I did on a Dynojet, but I put down 10 more whp. Our numbers were basically opposite, but either way, you're looking good.

The boost taper isn't from being "choked" up or anything, though. That's just natural for the stock turbo, and your ECU is controlling boost through the BCS, which makes it taper. The real boost is 20.3 peak tapering to 17.3, though, just fyi. Also, the majority of the power loss up top is due to the factory tune dropping to AFRs below 10 after 6000 rpm. That's why tuning gives us such huge gains even when stock.

 

Not to start a controversy the numbers are kind of high for a stock 05 on a MD, that is how much a stock 05 does on a Dynojet. Great numbers anyway.

 

We won't have a controversy I don't think. That's the beauty of a baseline. His car is probably making the exact power than an 05 is supposed to make, and the dyno is just setup similar to the one at CFT in Orlando. Since we know from the beginning, it won't be an issue I don't think.

 

It's irrelevant whether or not it's reading high.

That's why he got a baseline.

That's why it's so important to try and stick to the same dyno when tuning/modding etc...

(weather conditions taken into consideration of course)

People get stuck on trying to compare dyno numbers. You can't. It's apples and oranges...

I hope not sick of this the MD vs Dynojet crap.

Dynojets are inertia based dynos. When doing sweep runs, there isn't much fudging/tweaking that can be done to change the results. Therefore they are usually very "honest."

Load based dynos require lots of time to calibrate properly and need to be constantly adjusted for different types of vehicles. The idea is to simulate your vehicle driving down the road (load) where most of your EVOs spend their time. Lots of datalogging needs to be done on the road to determine how to properly set-up the parameters for the dyno. And again, each vehicle is different.
Therefore there is a lot of variability with load based dynos depending on the amount of time invested in their set-up for each vehicle.

BTW ... My 2005 boost peaks at 21 and drops down to 19.


Talon Those are some nice numbers.

Interesting.

 

IMO, this Dynojet vs. MD vs dyno XXX stuff makes NO sense. HP is HP. It is an agreed upon scientific meaure of power/force. All 4WD dynos should read the same HP on the same 4WD car, with a VERY small margin of error. Otherwise, we are not talking about HP on both, we're measuring different measures of power.

 

Looks like you need a tune, that curve is very jagged. Nice to see what my 03' will be at after I install the 10.5 housing.

 

Well, sorry, but that's not how it works unfortunately.

 

You got way more power than mee -- any mods u didnt mention

 

Nice numbers...thanks for the post...Even though I have a TBE, I plan to put the stock parts back on and then dyno the car.
