my first dyno run

Hasser · 05-16-2018, 06:26 AM

got my first Dyno run in today.

Hasser · 05-16-2018, 06:31 AM

Here are the graphs.

Currently running a fab speed sports cat and BMS jb1 tuning box.
Air intake is the M2 lower air box with pipercross filter
Exhaust is supersprint front and mid pipes with the M2 stock muffler.

Runs were done in 4th gear in sport plus with the valve open on the exhaust.

Car is a 03/2014 6MT with 17600 miles.

The JB box only gives peak extra 27bhp. Not as much as I thought.

But to get 369 bhp is what I was hoping to get as to match the M2 power.

I know there is a lot of discussion and variables with Dynos. But any opinions welcome.

I'm so jealous of those sea level power numbers. Altitudes a bitch.

Are those adjusted (ie flywheel estimates) or wheel horsepower?

Isn't it 15% loss FWD, 20% RWD, ~25% AWD?

That's my next move. Been reading a lot about that.
Need new fmic and charge pipe first I think.

Great info, thanks for sharing it - I so love these new turbo motors with that torque curve (or rather 'table') from almost idle on up.
