Hey guys,
I finally had a chance to spend more time on the dyno with my 2014 FBO GTR. I put 3 hours of dyno time doing the pump gas tune and another 2.5 into the E85 tune, so I can safely say nothing else is left on the table. This time around, I was testing some prototype fuel injectors. These are spray targeted to minimize the amount of fuel that impinges on the intake port walls. The reasoning is that as the fuel evaporates off the intake port, it occupies more volume, thus reducing the amount of air you can pack into the cylinder. It seems to be good for some additional power. I'm not done testing, but I wanted to know the art of the possible, so to speak. What is the highest dyno anyone's seen for a bolt-on only, no turbos, no wastegates, no engine internals, non-NISMO GTR?
Here's where I'm at right now: 676.29WHP / 621.87WTQ.
This is on a Dynojet with Standard Correction, dynoed in 5th gear, stock wheels and MPSS tires. The car made 497.8 / 449 stock with a catless mid pipe before, for comparison. Yes, all dynos read differently, and Dynojets tend to read on the higher end of the scale (thus me being OK with letting TQ creep up into the 620ft-lbs range for this run), but that's why I'm providing the stock dyno for a basis of understanding how much higher it reads. Assuming the mid pipe was good for zero additional HP before, we're looking at a gain of 178.5hp and 173tq.
Oh yeah, it also made 500foot pounds of torque at 2400RPM!
The setup is as follows:
Cobb 3" intakes
AMS Street intercooler
AMS Cat-less Downpipes
Fabworx Catted, Resonated Midpipe
Fabworx 4" exhaust
330LPH fuel pumps
I'm running Michelin Pilot Super Sports (285 all around). I had a chance to take it down the drag strip four times, but it spun so much that the car kept going into limp mode. Finally, I turned the wastegate duty cycle down by 5% globally and then down to 60% in 1st gear. It still spun all 1st and most of 2nd but managed a 10.67 @ 138.17mph with a 1.82 60'. It's got an easy 140+ mile-an-hour trap in it if I can get it to run full boost without uncontrollable traction loss.
Cheers!
