* Compression: 145/145/150/152


The D15B7 is officially rated at 102bhp, brake(crank) horsepower. By the time you get through the friction losses of the drivetrain and all that, others have estimated you end up with about ~85hp with the B7 engine. I couldn't find any dynos of an untouched B7, usually they have I/H/E and all that, so I didn't really know.

Who dyno's a stock B7 anyways?

I'm not sure how much the Colorado elevation would affect the power, or the miles, but the conditions were right and we had a dyno day here so I'm adding this to the internet's archives for anybody trying to expand their knowledge on now-known B7 data! Shabam!


The blue run was a little cold, so that's why the red ran better. Also I'm assuming from the early blue area that there's a significant power drop between 3300 and 4500 RPM's for the B7. Apparently D-Series.com member Jeremy85 noticed this mid-range drop too in a thread where Transzex/Mista Bone points out with before/after dyno's, tuning will take care of it. Ahh that Mista Bone

this is a great dyno sheet and info to show us little guys with the same motor where were really are starting. Thanks!

You got it man!
I'm a little guy too, hah

Perfect for testing. Thanks!

what is the compression of your cylinders? HAve you tested ?

cute lol. But seriously good info. I'm sure mine was pushin waaaay less than that by the time i pulled it lol

I have! Assuming this information is correct for the D15B7, my results:
#1 - 145
#2 - 145
#3 - 150
#4 - 152
Between 135-185 is considered healthy.
The gauge I used is probably 25 years old, so it might be reading low.
I'm going to get a new gauge soon and test again when I change my plugs.

The plugs look pretty good as well, although probably quite old.

right on! makes me wonder what I am pushing on my lil stock motor, seeing as how i have 299k and my compression was between 170-185 woohoo
