Ryan's car was a pleasure to tune; not so much fun regarding the axles though. The passenger axle was pretty "stuck". We wrestled it out, and replaced both axle boots, with a fresh re-grease.
Our dyno is setup SAE; ie, 0% correction. The car will make less power at 115deg ambient temp, so why correct it to read higher? There are too many variables and chances for "callouts" using correction, so we decided to set the dyno to SAE when we installed it March 20th. We had a Super V on there yesterday that made 127WHP. That same motor Engine-dyno'd at 162WHP. Do the math, the dyno is reading low, and we are OK with that.
Back to Blodi's car...
The tune was very solid from the get-go. I touched very little in regards to AFR, as it was setup very conservative at 12.5:1 under 5psi, tapering down to 11.5:1 at full 9.7psi. The timing was too conservative, and I don't blame the previous tuner. His usual cars blow ring lands at anything much over 10deg of timing. After adding 10 degrees of timing to his tune, Ryans car picked up almost 40WHP, even with the slipping stock clutch.
Installed the RPS, and it picked up another 9WHP, for a final 431WHP.
As far as torque down low, that's what the car liked. I tried more timing, it lost power down low. This is why a dyno is a necessary tuning tool, and why we made the investment of getting one in-house. We are able to actually "see" the tuning changes.
That's all for now. Blodi has a few small remaining issues that he opted to repair himself, as we are headed down today to pick up a certain Carbon Fiber NSX to prepare for a certain race, and it's the only chance we have to head south again for a week.

1st gear is basically useless even at half throttle......New tires are next.
