EPL K24/18G Dyno Results From Today
For those of you that like to decipher and analyze dynos, I have some interesting comparisons from today's dyno session with Tony at EPL.
Dyno #1: Previous extremely hot weather dyno vs. today's cooler weather with Speedtech 75mm Y-Pipe and dual snorkel air box added...shows what weather can do to a dyno. We picked up about 30HP and 350 RPM's of earlier spool. This was either due to weather, Speedtech 75mm Y-pipe, Vivid Air box or all combined (my instinct says a combination of all).
Next are two race gas runs at 1.25 and 1.27 bar. This is as high as we went with boost because the car made 610 AW Torque, which Tony felt was the safe limit for torque. Actually we did attempt a 1.35 bar run, but hit the TB shutdown at 1.35 bar. We saw 620 torque before the shut down and decided to leave the 1.35 bar TB shutdown in place and only run up to 1.3 bar on race fuel to stay around 600 AWT, as a safety measure.
Next is a view of the pump gas run compared to the race gas runs:
Here is pump gas and race gas, both at pump boost of 1.1 bar:
Next is the summary of the stats from the 1.27 bar race gas pull:
549.6 AWHP / 610.1 AWT
This one is interesting. How weather pump gas vs. cool weather pump gas (Y-Pipe/airbox added) vs. 1.27 bar race gas (Y-Pipe/airbox added):
And here is another really interesting one - a stock K16 car vs. K24/18G car (same temp/same dyno/ different days). For those of you wondering about the perceived lag of a K24 based turbo - Here it is in documented form... by 3400 RPM's it looks like it's game over for the OEM K16.
A few other notes:
1) We did not develop a separate race file, as the car made more power on race fuel with the current pump file, than it did with an advanced timing race file we tried. So one file does all for me.
2) The car was still increasing in power at 6,800 RPM's, where Tony shuts down the dyno, but the rev limiter is set for 7150 RPM's. Tony is certain the car would have dynoed higher numbers had we revved it up a bit more, but he does not like to go over 6800 with these cars on the dyno.

Wow, great results and diligent testing methodology. I've been putting off doing injectors, but I may just have to suck it up. Congrats guys!

Tony,
Thanks for the time spent on the car yesterday.
The car ran really strong on the highway. I only went a couple of exits with the race gas and it was tough to give it a good pull, due to traffic. Later on when the road opened up, the mix of race gas and 93 pump seemed to burn real well and the car ran great! We had a really nice ride home.

Great results guys! I've been extremely impressed at how well EPL software reacts to changes in temperature and gas quality. It's not very typical for a tune to be so versatile and tolerant to widely changing variables...I am once again impressed.

Would upgrading injectors be worth it on the 16/16G kit? If so what kind of improvements?
