<![CDATA[87 BUick GN, LS1 turbo video]]>heres a little something i taped tonight, i was bored. This really showcases the sound i was looking for with the 4" single pipe. the first run it spun into 2nd extremely hard, and i wasnt expecting it, so it went right into drive. This thing is seriously bitchin though, and i want anyone that watches it to please leave a comment. some specs
87 GN
pulled frame, boxed, stainless brake lines, 1/2" alum fuel line
every bushing on the car is new polyurethane
sandblasted and POR-15 frame and underbody
new fuel tank and walbro 255, (have a 2nd intank, havent installed)
6.0L LQ4, 9.4:1 compression
Lunati 224/224 112 .560 lift. had it from previous build
Moly pushrods
headers by me, 1 3/4 primaries and 3" collectors, Temporary 2.5" crossover (temp because i wanted it done and just used pie cuts, rebuilding this winter)
Pro Products Typhoon intake
Pro Products FPR
65# mototrons
HP Tuners 2-bar speed density
Borg Warner S400 turbo, 74mm
Powerstroke Intercooler (installing this winter)
4" downpipe, full 4" single exhaust, over axle with 2 Dynomax 4" race bullets, one after downpipe, one in front of axle
4L80E
stock truck converter

As of now, i went a 12.65@121 at the street legal this spring on 255/60-15 firestones. Also was only running wastegate boost, got 3psi in first, 6 in 2nd and 9 in drive. Never got above 70% throttle till drive as it would blow the tires off, also left off idle, 2.1 60'.

LOVE that sound though, plus arent these turbos the loudest damn thing ever? you should hear it in the car.
BTW, new timeslip coming this weekend, great track prep (brainerd) and now on 275/50-15 BFG drag radials
