It's Done!!!!!
PHOBIA had its date with the rollers yesterday. Dave worked his magic and here are the results as promised. ;)
This first graph is the overlay. The blue lines are the power and torque with the GT35, on a 100LL avgas, no catalytic converter and 20psi.
The red lines are the new GT3076, on 98, with a new exhaust including a 3 inch metal cored cat and 20psi (1.4bar)
Yeah, you can see it too hey, it makes a smidge more top end, but significantly more torque, and actually where it's needed!
I am ecstatic with the results, my first drive showed just how big the improvement was through the seat of your pants.
Here are the AFR, pretty good considering there are 8 injectors that require staging all run by a primitive Delco computer, full credit to Dave.
Obviously, at 20psi, this was a pretty conservative tune compared to the 25-28psi the motor has run in the past. But, I have come to the realization that it's not going to win anything for outright power, so I just want a nice package that I can actually do some klms in now.
Yep, I’m buzzing and can’t wait to get out and enjoy it.
