JB4

BMWhoarder · 08-17-2014, 05:01 AM

just wanted to share my dyno results from the other week.
Car is completely stock (n54) with a JB4, was running on map 5 with a 50/50 mix of e85/ BP 98 at the time.

Pretty happy with the result. I did unfortunately hit a cut just after 5k rpm on my earlier runs so not sure if there was anything left it in. Have since put the backend flash on which apparently should help. Not going to get back on the dyno for a while though.

Next mods are and inline 255 to help handle the e85, followed by (probably) a bastuck quad exhaust. will see what funds i have left in the kitty after the house is finished.

Nice result.
Happen to do a baseline run on map 0?

Excellent result. What are you doing about cooling?

That's seems a bit high for a stock car with only JB4

Our E88 managed 263kW on map 5 with E40 and only DCIs. Definitely doable but only good for about 1 run before the heat soak.

Currently? Nothing. Given i live in Canberra and we see a maximum of 14 degrees for a significant portion of the year, IATs aren't too bad.

Might look into a bigger FMIC down the track, but i'm also not planning on doing much more to the car after the listed mods, given it's my daily driver and i'm more focused on directing my funds towards the house now.

Good result. Would've been a nicer graph and log if done in fourth gear.

the run was done in 4th
