Wassup!
I made it out to Test N Tune last night and had a few runs on my new setup. Yes, I'm playing with an EVO 3 turbo on my DSM. I also converted to E85 when I changed my turbo setup. The learning curve has been quick and very enlightening! My best time was 11.233@ 127.736 mph while granny shifting each gear. I'm very happy with the MPH, it shows the potential in the car. I guess that's not bad for my first time out on this turbo setup. Next I have to work on the shifting and get a little more seat time to adjust to this small turbo. My datalogs show a few other areas that can be improved, so I have some ideas for my next track day.
I also had a chance to put the car on a Mustang Dyno to dial in the tune the day before. I'm glad I did because I made the best power and torque when I removed 2 degrees of timing! I was suprised that power held up through high rpm as good as it did, especially since boost dropped off steadily from 5500rpm/30psi down to 7500/20psi. I'm sure the wastegate is blowing open, it's a 34mm flapper. I prefer the small wastegate for high boost, but I got this turbo used for $200 so I'm not complaining. My best dyno run was 408 AWHP, but the torque was erratic, so I worked on the entire powerband and finalized the tune with a few less hp and more torque across the rpm range.
Here's the dyno and timeslip. Sorry it's hard to read, I think somebody needs to change the ink cartridge.
402AWHP between 6350 to 7200rpm / 375 TQ@ 4100rpm
In case it's not clear, the timeslip reads
Reaction .068
60' 1.578
1/8th 7.236 @ 96.021mph
ET 11.233
MPH 127.736
