Oh damn. Yeah this is pretty far behind.
Well to catch up, we spent a considerable amount of time chasing some boost leaks and ultimately an odd exhaust restriction limiting the boost at 20psi and causing things to be rather laggy. Also discovered during our testing that cylinder 3 had low compression due to some valve seat issues. Most likely from the old engine when the piston melted. I had the head gone through and rebuilt with a 3 angle valve job and some Manley single springs from my buddies over at Force Engineering. Also put a set of HKS 264/272 cams and oldschool AEM gears from a friend while things were apart.
Back to the lag and boost issue. We were seeing full boost around 4800rpms and couldn't get more than 20psi out of it. Tried different wastegate springs, countless boost tests, vacuum routing, even blocking the wastegate off completely and nothing. We were ready to junk the Tim's Turbos .63 housing in favor of a Bullseye .70 when I discovered something ironic while checking the car over the weekend before shootout. The crappy 2.5" temporary exhaust that I had made by a local muffler shop to mate to my 3" downpipe the previous season had a 2" diameter resonator flared to fit a 2.5" pipe!!! I had an 18" long restrictor in my exhaust! I yanked the 2.5" setup off, backed the boost controller all the way down, and tried an open downpipe pull. I couldn't keep it under 30psi with the 20psi spring in the wastegate. Lesson here: Don't cheap out on exhaust. Go big or go home. -Literally.
I quick ordered a section of 3" & a turn down and we made a new exhaust dumped before the fuel tank under the car two days before Shootout. The car made it there and back great and I did an easy shakedown pass while there for shits and giggles. Didn't try heating the tires or launching it but just rolling it out off the line on junk drag radials I ran a 13.9 @ 120 with a 2.4 60'. It's easily a mid 120s car right now and gets awful squirly in 4th unless the tires are good and hot. 1st-3rd is a joke.
We've since had some fun picking on some local vettes and such. Never got around to making a serious attempt at the track. I did dyno it a couple weeks ago at the Force Engineering dyno day. Made 424/395 at 25psi with a "safe" street tune and very little timing. My 1050s are at something like 115% idc so i'm thinking some 1650s and 30psi should be good for a solid 470-480whp with some actual dyno tuning.
Lets see if the video works

Plans for next season:
Weld the diff
Probaby an unsprung 6 puck disk while the trans is out
24.5" slicks
Galant knuckles with 2 piston front brakes
Custom rear coil springs. I'm thinking 300lb qa1
FIC 1650 and more boost
10an crankcase vents
And a couple current engine bay pics
