So its been a crazy 24 hours for me. I have been trying to meet up with my friend who tunes my car but its been very difficult because he is getting married in 3 weeks and doing all the last minute stuff. So last night he tells me that we can spend some time later at night street tuning it.
I meet up with him about 9:45pm, spend about a half hour in his driveway just checking my sensor values and feedback via the laptop and AEM EMS datalog. We confirm everything is working right and head to the highway service road. FUCK. They are re-paving the highway so ALL the traffic is diverted to the service road. So now we are just driving around at normal highway speeds checking everything and tuning small areas of the map to make it drive better at part throttle and in varying traffic conditions. So my friend spends about 15 minutes doing that and says, "Lets turn her loose" So we search and finally find an empty 3/4 mile or so of service road and do some 3rd gear pulls, we do a total of about 4 or 5 pulls, spending about 30 minutes doing actual tuning adjustments. We call it a night and go home. Im asking him how he feels about the car and this is what he says "This thing is making ALOT of power for the amount of tuning and boost thats into it. The car feels stronger than I thought it would, I wouldnt be surprised if your making in the high 300's if not low 400's at the wheels"
Next morning (today) i've got it in my head that I need to dyno this car just to get a baseline and see where its at. So I make a few calls and I am given a short 30-45 minute dyno slot just to do a few baseline pulls to see where im at.
DynoDynamics Dyno normal 1.15 CF (No smoke and mirrors manipulating #'s in the software to make the readings higher, I asked to see all the variables before hand, plus I know and trust these guys I have been doing business with them for about 5 years)
First pull (no dyno sheet or video) 440whp, 442wtq, 21psi, 93 octane pump gas, 11.8 AFR, 11.5 degrees of max timing. WOW WOW WOW. The car makes 440whp on its first pull ever with this setup. The AFR is a little lean for his liking, especially since its about 75 degrees out, but at night around here its about 60 degrees, my tuner was concerned it would go too lean if it was colder. So he adds some more fuel to the map.
Second pull, 432whp, 430wtq, same boost, same gas, same timing, AFR around 11.3 and stays nice and flat all the way thru.
3rd pull, 432whp, 432wtq, same everything as 2nd pull.
The car needs new plugs, the spark is unstable above 6000rpms and the spark is being blown out completely at 7000rpms. The plugs were also gapped a little too high around .028, they should be around .023 to avoid blowing out. Next week she will get RalliArt plug wires and new plugs, gapped correctly : )
All in all, I am very happy with the results, for the amount of time spent tuning, the amount of boost, the extremely safe AFR and timing and the car runs and drives well and its fun again to drive. I am also at a disadvantage still using the HKS 272 cams since their performance has been far surpassed by the newer cams from GSC and Kelford. GSC is going to be releasing a 2.4/EVO head specific lift/duration cam in the near future, im going to hold out until its available. With better cams, more boost and a little timing, this thing can easily do 500+ on pump gas. For me, im OK with the current power for now and will push it higher on race gas (to keep it safe) in the very near future. Vids and graph are below. Graph is cut short because it got all crazy with the spark issues. The spool is a little slow also since we arent running much timing, once we spend a few hours really tuning the car over again im sure 20psi will be reached around 3900 or so, now its about 4300 or so.
