I don't know of a multiplier for converting.

I have about 6 dyno sheets from the other local Dynojet shop now. They vary in the amount they are off actually. The lower the HP is on the car that dyno'd there the closer our dyno is. The higher, the further off. I would guess it is a percentage. It looks like on average it's about 11%.

Al's car would typically dyno 650-660 whp they way it was setup this weekend. Here he only dyno'd 580. That is pretty close, that would make it 643.8 whp. Looking at it that way it makes sense, seems like from all the sheets I have it is about 11% less.

Very interesting actually. I had a MD owner come to me this weekend and ask if we re-calibrated our dyno when it was delivered. I told him no. He said that his roll weight was 3333.75 on his when he got it but when they went throught the calibration it went up to 3600 lbs. Now that I do the math that is just about 11%, close 3699.63. With that change the numbers would be the same.

It is odd to me that two machines of this mass could have the exact same roll weight, actually it is impossible. I wonder if the 3333.75 is a default number that is just used. I am going to let the machine run through it's calibration and see what comes up, it meaures it's weight somehow and uses that as the calculation.

I will post more after I do the test.

Funny stuff. Started a new dyno thread and wanted to go back and review some of the testing I did in this one. Some where around page 3-4 I said I will NEVER get an AWD Dyno and that a dyno is a horrible investment, anyone thinking they will buy one and make money using it is nuts! haha Now I have a new building to house our new AWD dyno and the dyno pays for itself everyday it is here! How things change

The Dynojet numbers are high for sure. From the data I posted here over a year ago, comparing it to what I am reading on our AWD MD dyno looks like about an 18% loss running on this dyno over the 2wd Dynojet.

I am looking for gains in power for this next round of testing. Just hope the gains stays consistent.

Check out the new thread.

Someone mentioned 3625lbs being listed as the Evo weight used. Your lower readings may be attributed to that as 3300lbs is used industrywide. Weighed in at Moroso on the MR (heavier version) with driver 3375lbs. I would assume the lighter GSR would be correct at +/- 3300lbs. FYI.

 

WEIGHTS (RS - Evolution VIII - MR Edition)
GVWR (lbs/kg) 4222 / 1915 - 4222 / 1915 - 4222 / 1915
Curb Weight (lbs/kg) 3219 / 1460 - 3263 / 1480 - 3285 / 1490

 

The weights industry wide, atleast with Mustang Dyno users, shouldn't be 3300#'s as that isn't what they supply. You get a huge "look up chart" as a database when you get the dyno software. The weight in there is 3625 and HP at 50 mph is 15.1.

We were dyno'ing a 1G AWD today using the supplied input weights, we then switched the weight and HP @ 50 mph to what another MD shop used. The weight was about 200 pounds less and the HP @ 50 was 2-3 hp less, the HP actually dropped but only by about 4-5 whp.

Do me a favor if you can Dave. I have looked at a few other charts on MD. Can you try weight 3350, HP @ 50, 13.0 and also 3300lbs, HP @ 50 11.8. Part of the problem is from the best of my knowledge yes, there is a huge lookup table but no, Lancer Evolution is not listed on there. Only regular lancer with different aerodynamic qualities as the Evo. Maybe since your dyno is brand spanking new, they have added a lookup specific to the Evo VIII by now. MD also flew in to set up the local dynos.

 

Nevermind Dave... I found this:

 

Yup, an average car will have a HP load at 50 mph of 13.0, but an AWD car has more drive train losses than your average car, and thus uses more HP to travel 50 mph than your average car. That is why we don't get 30+ mpg out of our 2.0 liter engine

Still can't help but wonder the back to back differences in these settings and why MD would calibrate BR's with a weight of 3625lbs when Evo's don't weigh that much.

 

I don't know, but what kind of person would do a WOT run on a cold engine?

 

What the hell are you talking about?

nothing, wrong section.

"Now I have a new building to house our new AWD dyno and the dyno pays for itself everyday it is here! How things change"

Are you talking about in terms of using it as a tool for tuning w/o having to mess w/ 2wd (extra labor) or people just wanting to have their car dynoed?

 

I was about to ask the same thing .

 

I have learned that when it comes to all things 4G63 David Buschur knows more than most and is hardly ever wrong

here is what he had to say in another thread

 

Not sure why Tim @ MD would write what he wrote, maybe that was before the newest software was released.

Anyway, my charts go to 2005. The dyno is not calibrated for an EVO, the EVO is in the "Lookup tables". Listed as 3625 and HP at 50 mph is 15.1.

I have tried 3300 and 13, it dropped the HP by about 4 whp.

Bottom line is this. I probably have one of the only MD's that nobody dicked with to try to get to read higher. I could care less about the number. I want a dyno that gives an accurate tune and this one is dead on the money.

VERY pleased with the tunes coming off this dyno.
