1986 supercharged c4 possibly making a trade with this guy just wanting to see how much its really worth. its a 1986 c4
Last dyno I had (with a seriously lacking tune) yielded 390 rwhp and 543 rwtq. Assuming a 19% drivetrain loss (given the 9.5" converter), that puts it around 480 chp and 670 ctq. I can tell you this, it's a neck snapper on the throttle!
looking for $10,500
Here's the goods:
Engine:
1986E Silver Metallic Coupe
140,000 chasis miles, engine and transmission have ~4,100 miles
Rebuilt 7,000 original mile 1986E shortblock
AFR 195 65cc Eliminator heads
9.42:1 static compression ratio
TPIS Big Mouth intake base with SLP large tube runners and ported plenum
BBK 58mm TB
42# FMS fuel injectors
224/234 @.050, .465/.488 114lsa supercharger cam
Blowerworks L98 supercharger kit with Vortech V2-SQ compressor
Blowerworks Gen II Water/alcohol injection with boost controlled activation
Dual Walbro 255lph fuel pump (1 inline, 1 in-tank)
New Thin Film RTD Sensor similiar to the LS1/LS7 etc. MAF sensor from Blowerworks
MSD 6A
New .bin file with injector pulsewidth cap fix
New Ostrich 2.0
Plug-n-play tuning capability with TunerproRT
New water pump installed on rebuild
1.6 roller rockers
Holley AFPR
Pulleyed at 3", but boost restricted to 10lbs via and inlet restrictor (otherwise she'll push 12 psi at 5,700 rpm)
New engine has only been run on Amsoil
Driveline:
Custom built Pete K 700r4 with hardened input sleeve (I had a list of all the tricks he built it, but I can't seem to find it)
9.5" 2,500 rpm stall converter
D36 2.59 rear end (have a set of 3.07's, but no 3-series carrier)
Exhaust:
TPIS long tube headers with SLP mufflers and Dynomax y-pipe
New converter plus hollow Raymond Tech cat
Miscellaneous:
New power brake booster
New rotors and pads
1990 ZR-1 Wheels (not perfect, but stripped and cleaned) with 285/40 and 315/35 Goodyear GS-C's
Swapped 1986 Medium Gray sport seats, non-functional (have original cloth seats), drive side bolster has some wear
Just replaced all carpet, painted trim, and installed sound suppression material less than 400 miles ago
New center console and shift boot
A-pillar mounted boost and A/F ratio guages
Newly installed rebuilt instrument cluster
A/C converted to 134
Paint shows some flaking in small places on the urethanes, front and rear. The finish isn't perfect, and definitely was repainted before I bought the car. I'd give it a 6 out of 10.
Bose stereo and tape player function normally....just can't hear it much over the exhaust!
Cruise control and A/C function normally
