that graph looks like me drawing on paint.

 

or my 2yr old neice....but thats about the same thing...

 

not my fault she copied me.

 

How much whp was the merc and m3 ??? Anyone plz

 

e55 was 350hp and m3 i think was around 440hp?

 

that's all the e55 PUT DOWN?? what was the torque like on the E?

 

not too sure. jeremys got the numbers. but ya the loss was pretty big and he said something about leaking boost so idk. those mb autos have a lot of drivetrain loss relatively speaking.

 

Are the dyno jets usually under rated or over rated when they show HP and TQ numbers?

I think they run conservative.

 

i think they run accurate...

 

Are they pretty accurate? Im not sure, i have heard so many things about so many dynos i dont know. Just asking

Well compared to a mustang dyno and any other, they are rated higher. Its the preferred dyno to show off your numbers.

 

really i heard just the opposite

 

yeah i think the mustang is the one to show off numbers....dynojet is the more accurate one from iv seen

as a bit of facts to go with it....an '03-'04 will show about ~230 give or take on a DynoJet which falls in line with an average 17% loss from crank

 

No sir, Mustang Dyno read 11 or 12% lower than the Dynojet.

Take my car for example, when originally tuned @ Japtrix on their mustang dyno I made 385rwhp. Went on a dynojet made 435rwhp. Lets do the math, 385 + 12% (46.2) = 431, so factoring conditions and all thats about right.

As an aside, the dyno operator can adjust the MD to read the same as the DynoJet. I know a few tuners who only go by a Mustang Dyno as a indicator of "real HP".
