Thanks for the kind responses guys!
This past Sunday, Sky made the trip to the big north to install and dyno test our headers. Sky's 05 NSX has the SOS supercharger on top of a Driving Ambition intercooler and 3.5 liter stroker motor.
We strapped the car down to the local Mustang dyno and it made 476.8WHP and 380.9WTQ. Sky was dissappointed because the car made over 550WHP on another dyno. I explained that every dyno reads differently and that this dyno in particular is a "heartbreaker".
We then loaded the car back into the trailer and headed back to the shop to install the headers and adapter pipes. The install was very straightforward and after a small adjustment to the rear adapter pipe, we were set for the dyno again.
Sky's NSX picked up 15.5WHP and 9.6WHP over the headers that were installed on the car!
The car picked up bucket loads of torque under 4500RPM and it's easily noticeable on the street. When punching the throttle in 2nd gear with the baseline numbers, the car was relatively "stable". With the LoveFab headers installed, 2nd gear easily spins the tires(TCS off) accompanied by strong acceleration throughout the RPM band.
One interesting thing to note is that supercharger boost
decreased by as much as 1.2 psi. This is due removing the "bottleneck" of "standard" NSX headers which allows the engine to injest and expel air more efficiently. I'm now very curious to see how a 2.5" collector would perform with a supercharged car....another time.
There were a few spots in the fuel map that could have used some fine tuning but unforunately, we lost the rear 02 sensor functionality, and it was getting late as Sky still had an 8 hour drive to get home. We rushed back to the shop to replace the sensor so that Sky could safely return home.
Overall we are very happy with how the headers have performed throughout the last 17 months! They have shown gains in every situation for which they were designed and have improved horsepower and torque with several different applications.
We have several orders on the bench but are more than happy to accept more!
