Such a great event, thank you to Brian for coming out and tuning our cars and even staying after to help troubleshoot some! Thank you to Jerryl too for coordinating the event, i truly wish we can do this again in the future with more attendees.
The dyno itself wasn't reading HP, torque, or RPMs accurately, so unfortunately we didn't get any accurate numbers there. Luckily, i have XFI on my car so i took it as a place to make safe hits and work on the tune to make sure:
1. The targets set for timing and a/f are as close to actual
2. The car was mechanically sound elsewhere, and through the use of our butt dyno determine if i can raise the boost or if i would be maxed out based the limitations of my combo.
We made a total of only 4 hits on my car, and Brian was able to determine the its ready to hit the track. All of the hits on the dyno were at 25-26 psi. We tried turning it up on the last two hits, however with an internal wastegate it looks like the hole i have for the puck is too large.
The Butt dyno says about 620hp to the wheels, and if you factor 20% drivetrain loss that's 775 at the fly wheel. But since we used the butt dyno, and are unsure of actual drivetrain losses, those numbers aren't 100% accurate. I do trust Brian though, and if he says it's around 620 to the wheels then given the amount of cars he's tuned in the past i'll put money on the fact it's close to that.
I was having all sorts of issues with my car so i wasn't sure if i was even going to be able to dyno it. This morning i kept blowing my ignition fuses, luckily i figured that one out pretty quick but then my Alky Control kit wasn't getting any power! Scratched my head for hours, traced essentially the entire wiring harness for the kit and found nothing. My original dyno time was 11:45 AM, and we were finding these issues at 11 while being 40 minutes away still. So i called Jerryl, and luckily i was able to switch with the guy who was supposed to go at 5:15. So that gave me time to fix the issues, which wound up being the loose CAT 5 (?) connection under the dash for the alky control. It's the old school telephone cord one. Plugged those two connections to each other and alky kit worked fine.
