Last April:
Yesterday:
We'd made a few changes (Exhaust, Tune/tuner, Boost controller) from our initial build. Went to the track twice in Dec. since the above times were posted in June, and ran 11.74. Came away satisfied, but not real pleased.
Truth is, the stooopid HKS EVC-S controller manual is
indecipherable and led them to stop 'tuning' because it was boosting off the charts. I did some searching, found out how poorly translated the default settings were, and we changed them. (The distributor was clueless.)
I asked to return to the dyno to verify. Now, John Visconti (V-Tune) made numerous changes to the map and was able to achieve these numbers with relatively safe AFR's (Relative is a keyword. AFR's aren't the only thing to be cautious about at this level.) 12-13 lbs boost. 93oct (w/10% ethanol here in the NE)
Also glad to see the ARK Grip exhaust is WELL up to the job, and quieter. They tell me they tried to run it in 3rd and it poured smoke off the tires--low reading. Just too much!
Anyway, what you see is a pull in full-out KILL mode--suitable for a track run in April or March. 11.5's here I come....
Fortunately the EVC-S has a second programmable mode, and that lower number is how it came into the shop, and how I'm driving it around.
Yup: Stock block.
Haters gonna hate! Drove away after a lot of abuse, and it was purring like a stocker. These are good engines!
We'll be ready in March for a track day at the strip.
