The weather cleared for a near-perfect 60F day so I headed out to the opening day at Woodburn Dragstrip.
I found a 3" slice in the inner sidewall on one of my tires while checking everything the night before so I took the 17" BBS wheels from Evo and put them on the Talon.
The goal was to make some shakedown passes at low boost and low timing on pump to see how it shifts, converter, etc. It's a 50 mile drive so I didn't want to break anything by getting greedy before going back to E85.
I also finally weighted the heavy pig: it came in at a svelte 3600lbs with driver and a half tank of gas!
First pass of the day was a 12.9 @ 110mph at 16psi and 9* of timing on a half tank of 92 and 2 gallons of VP110 (2.0s 60ft!). I had some persistent knock of about .4-1.1* through third gear so I took some timing out and richened it up a little.
The 60fts were terrible all day, it was lazy on spool and I was launching at 4000rpm with 12-15psi. Again, it was just to get some seat time and make sure everything was mechanically sound. I also have a pre-wastegate exhaust leak from the O2 housing (which is getting sent back to MAP this week).
Best pass of the day was a 12.701 @ 110mph with a blistering 1.9s 60ft (might as well be FWD with how soft its launching!). Average boost over the run is about 17psi, with 4* of timing for most of the run ramping up to 8-9*. It shifts out of first at 6500rpm and 7000rpm into 3rd and is trapping around 7100rpm (might need bigger tires when back on e85...).
Also, coolant temps were a little too high for pump, but I still have my winter 195F thermostat in so most passes started around 200F and ended around 206F, but were as high as 213F.
All-in-all I am more than happy with how it went, it was a fun stress-free, problem-free day on the track with my Talon, can't get much better than that.
The log is attached from the 12.7 run, check out that timing curve!
