So we pieced together a homemade manual boost controller to up the boost, .8 bar was just too slow. We decided to go to 1 bar. We tuned to .82 lambda. Well the car still felt slow
So we decided it was time to race against my Nissan. We all figure with its power it is a high 11 second car, so a pretty good benchmark. We did a roll from 20 in second gear. To both Ben and my surprise the BMW just pulls and pulls on the Nissan. We did it again and the result was the same. So we decided to get the Nissan spooled a bit more and rolled from 40. BMW still pulls, especially pas 100 MPH where it just stays in the power band. BMW is planted at speed and quiet. We did a pull the other day for tuning in 5th gear up to 140 without realizing it, felt like 80.
So its really messing with us because its so well behaved and just feels slow. I guess its a good tune and very smooth power delivery because even with 205 series tires traction in second isn't an issue. The Nissan was dyno'ed at like 340whp so we estimate maybe 360hp? from the BMW.
Waiting on ARP Head studs. Going to 1.4 bar.
