TTS Rotrex Supercharger C38-92 Build Thread
The Plan:
Stock Like. No crazy vibrations from after market motors mounts and no crazy exhaust drone.
The Build Begins:
2003 AP1 S2K 135K miles.
Ferrea beehive springs and titanium retainers.
Stock exhaust.
Stock 4.10 Differential.
The Supporting Cast.
AEM EMS Series 2 ECU
AEM 30-4100 Wideband
Hondata 4Bar Map sensor
AEM Fuel Rail + AEM Fuel pressure regulator
Injector Dynamic 1300cc Injectors
ACT Heavy Duty Pressure Plate + Competition Clutch Segmented Ceramic Disc
Defi 60mm Boost Gauge
GM Flex Fuel sensor
AEM 320L E85 Fuel Pump.
The Teaser.
The Plate.
Day1&2
Installed AEM fuel Rail, ID1300 Fuel injectors, AEM 320L Fuel pump and GM Flex fuel.
GM Flex Fuel with harness. $80 something shipped. The flex sensor in between the return fuel line. The hose line is a bit small for the flex sensor. Trick is to screw in a bolt to stretch and enlarge the fuel line to fit the metal hose. Then use fuel injector hose clamps secure the line.
Day3:
Crank pulley. Funny the instructions were for right hand drive cars. Wonder how much forward movement the engine will make. Awfully close to the steering rack.
Forgot about the lower left bottom screw that goes into the timing cover. For the life of me, I can't get the screw and spacer to fit into the timing cover. The steering rack is in the way. Must be another right hand drive situation. Will go back and remove the plate and try again.
Day 5
Thanks for the tip 06S2k07Si and RainH8R. Loosen the passenger engine mount and jacked up the engine. Took less than 5 minutes to complete the task. Saved me a couple hours to fiddle with the supercharger plate
Mounted the intercooler and pipes. The air con dryer moved and lines bent back. Looks nothing like the instructions. Took extra precaution and ground the bottom of the middle bracket to create more room for the intercooler pipe back there.
Had to bend the AC lines out of the way to fit the charge intake pipe. The Forge blow off valve is huge. Closing the hood is a challenge. Had to bend the hood latch stand slightly away from the blow off valve.
One thing I don't like. No brackets to secure the intercooler pipes to the throttle body. The pipes flex too much and will cause problems in the future. Zipped tie the intercooler clamps to frame to secure it a little more. May need to fabricate custom brackets to secure the intercooler pipes.
Log:
Day1: Installed injectors and fuel rail. Installed Nvidia straight pipe and Wideband O2 sensor.
Day2: Installed fuel pump.
Day3: Semi Mounted the supercharger.
Day4: Rest
Day5: Mounted the intercooler and pipes.

Car was sputtering up in the 7K rpm and whp was flatten out in the high rpms. Idle was lumpy and all over the place. Changed to ID1000 injectors and still had the same problem. Found out one of the coil was bad. These coils probably had 115K miles on them. Replaced it by process of elimination and the car idled like stock and pulled strong to redline.
Put about 1000miles on her so far. No major issues. Still tweaking the tune. Everything is holding up. Leaning out up top. The fuel pump is still on the stock harness. Will rewire a relay to see if I can get something out of the AEM320L E85 pump before switching to a bigger pump. Injector duty is at 100%.
The graph below is on E85, ~10K rpm @ 20psi with 20ignition timing up top. Knock volts are between 2-3 volts @ 8-9k rpm.
This is on stock exhaust with a test pipe. The first run is in red. Added more fuel on the second run (blue line).

Will be street tuned by me. It should be an easy tuning process as I already mapped out my other S2K with the PTuning kit on flex fuel.
This will be my second S2K and looking to sacrifice some power for a comfortable daily drive. Other than that, I'll see what the difference between a turbocharger and supercharger is all about.
