698 rwhp now

[TurboTA3.8]

We've been tuning the TTA a bit more today. Still having wastegate spring issues until the new one arrives.. Running max boost of 23.2psi, we will be running 32-35 with the new spring.

Guess the air fuel ratio went up a tad

Hard to get regulated boost on the rollers. I watched Cal's car at it was all over the place. FWIW his stage motor made 676 RWHP on a superflow at 24 PSI = 730-740 on a dynojet at 12:1 AFR without an IC on alky.

At 37 PSI he ran 8.58 at 162. So your numbers for the boost looking good.

Ya guys with the stage motors...

Congrats..

What are you using for engine management?

Have you tried going to 12.0-12.2 on your air fuel ratio? If it has a wide band, it should be able to be set and do that automatically?

Intake temps hovering in the 150-160's?

fast managment

its at 11.3

Curious, I guess your MAT sensor is installed in your intake... what temps were you seeing during your pull?

Are you keeping it at 11.3 to be safe? Or its just how it ended up?

Thx
